Last Tuesday, we had our official "Grand Opening" for the new Tucson Executive Briefing Center!
We sent out fancy invitations to all the IBM executives who supported this center, local dignitaries from the Tucson and State of Arizona level, and all of the IBM employees on the Tucson campus.
Since our new center is significantly cozier (5700 square feet versus our previous 15,000 square feet), we split the day into two separate events. The first for the IBM executives and local VIPs, and the second for the rest of the IBM employees on campus.
Of course, there is no free lunch. The day started out with a series of speeches. My manager, Doug Davies, was the master of ceremonies to introduce each speaker.
Alistair Symon, IBM Vice President of Enterprise Storage, explained how important storage affects everyone's lives. If you use an ATM machine to withdraw money, for example, you are most probably using IBM System Storage behind the scenes. Nearly all of the IBM disk and tape storage products are designed here in Tucson.
Bruce Wright (shown here) directs the University of Arizona's Office of University Research Parks, serves as CEO of the UA Tech Park, and the founder and president of the Arizona Center for Innovation. Bruce said a few words on how please he was that IBM decided to reverse its July 2011 decision to leave Tucson. The UofA owns all the property, renting back four of the eleven buildings back to IBM, so is effectively our landlord. Next year will mark the 20th anniversary of IBM's sale of the technology park to the University.
Tucson Councilwoman Shirley Scott talked about the improtance of high-paying jobs to the local economy. While IBMers in Tucson are paid less than our counterparts in San Jose, Austin, Raleigh or Poughkeepsie, we are certainly [paid more than the average Tucsonan], thus helping to raise the standard of living here.
Dr. Michael Varney, president and CEO of the local Tucson Metropolitan Chamber of Commerce, praised IBM for its strong reputation in ethics and diversity.
My new second-line manager, Karl Duvalsaint, and my new third-line manager, Doug Dreyer, emphasized the importance of co-locating Briefing Centers in sites that have Research and Development activity. It is important for clients to interact directly with developers, and it is also good for developers to understand directly from clients their needs, preferences and requirements. Worldwide, the IBM Systems and Technology Group has only twelve Executive Briefing Centers, and the Tucson EBC is one of them.
This is not to say that IBM does not have centers in other locations. Our newest client center in Singapore is a shining example. Of course, if they want experts to speak to clients there, they need to be flown in. Doug Dreyer mentioned that IBM plans to launch six such centers in Africa as well.
Next was the ribbon cutting. From left to right, Lee Olguin (our Gunny Sargeant), Tucson Councilwoman Shirley Scott, UofA's Bruce Wright, IBM VP of Program Management Calline Sanchez, My second-line manager Karl Duvalsaint, IBM VP Allistair Simon, my first-line manager Doug Davies, Tucson Chamber of Commerce President Dr. Michael Varney, and my third-line manager Doug Dreyer. We had a member of the local high school band do the drum roll.
Once the ribbon was cut, the IBM Executves and local VIPs were brought in to see the new facility, which has two large rooms, one common dining area, an 800-square foot green data center to showcase our products, our own set of restrooms, a galley to stage up the food and beverage service, and two smaller rooms for private conversations or conference calls. A local high school band provided live music throughout the day.
Wrapping up my coverage of the 2013 IT Security and Storage Expo in Belgium, I noticed some interesting things in the other booths.
The EMC booth had a whiteboard so that clients could do some one-on-one collaboration. All of their cocktail waitresses were wearing sharp pin-stripe coats with matching mini-skirts.
Another booth had a "virtual graffiti wall". Using a "digital spraycan", you could write on the wall. I am not sure what connection this had with anything the company had to offer, but perhaps they also wanted to collaborate with attendees on solutions. In either case, it was very cool, and brought a lot of traffic.
(FTC Disclosure: I work for IBM. I was not paid to mention any of the other companies, their products or people on this blog post. Mentioning other companies is not to be considered an endorsement of any kind.)
There were some interesting costumes. Leila from [Aerohive] wearing a "bee costume" complete with black wings. Hans from STS in a bright orange business suit. (Orange is the national color of Belgium). Sophie from Fortinet handed out champagne. The plastic glassware were cones that snapped onto her tray, but they had no flat bottom to rest your glass down, so you had to hold it the entire time until you finished drinking it. The Homer Simpson sticker eating the Apple logo shows the Belgians have a sense of humor!
The NetApp booth had a huge banner claiming that "Data OnTap" was the #1 storage OS. Obviously Windows, AIX, Solaris and Linux aren't consider "storage Operating Systems" per se. Is NetApp claiming they outsell FreeNAS, the only other storage OS that I can think of?
While IBM and I.R.I.S-ICT easily won the "Best Looking Big Booth" award, I have to give the "Best Looking Small Booth" award to my friends at Hitachi Data Systems. Like EMC, the Hitachi team did not have any equipment on the floor, but they made use of their tiny space by having a Japanese theme, with cocktail waitresses in kimonos.
Continuing my coverage of the IT Security and Storage Expo in Brussels, Belgium, we had a nice reception Wednesday evening.
Clara handed out Ceasar Chicken salads. Joelle handed out small rolled up pieces of duck.
Ilsa is an IBM expert in System x, VMware and the PureSystems family on hand to help with the demos and any client questions. I.R.I.S.-ICT employee Ans is only in her 20's, but is recognized as one of Belgium's leading experts in System z mainframe. I used to be the lead architect for DFSMS on z/OS, so we had plenty to talk about.
Of course, the best time for the press to ask for interviews is during the reception, where everyone is relaxed and ready to speak. I am "media-trained" which allows me to speak to the press about IBM matters. I do a lot of these interviews either over the phone, or on camera.
I took a picture to capture the typical setup. Mandy on the left is asking me questions, while camera operator Lisa focuses on my body language. The trick is to spend 80 percent of the time focused on your interviewer, and then 20 percent looking into the camera for strategic pauses. If Mandy decides to use any of the footage, she will be sending me the YouTube video link!
Hans and Sophie from Veeam stopped by the IBM booth to say hello. (See 2010 Aug 27 blog post comparing Veeam to Tivoli Storage Manager). These two DJ's kept the IBM and I.R.I.S-ICT booth hopping.
Belgium is a small country, and many of the IT storage people know each other. This made for quite the party! Our group closed up the booth around 8:30pm and we went over to join their friends at Arrow and Huawei. Here is Maiva from Huawei.
Continuing my coverage of the IT Security and Storage Expo in Brussels, Belgium, we had some great storage solutions on display at the IBM and I.R.I.S-ICT booth.
Here my IBM colleague Tom Provost is showing the front of the "Smarter Office" solution. The second photo gives the view from behind. While I always explained the solution from the front of the box, many of the more technical attendees at this conference wanted to inspect the ports in the back.
This sound-isolated 11U solution combines the following:
The [IBM Storwize V3700] with 300GB small-form-factor (SFF) drives provides shared storage for the servers.
Two [IBM System x3550 M4 servers] that can run VMware, Hyper-V or Linux KVM server hypervisor software for your Windows and/or Linux applications. These are two socket servers that can have up to 16 x86 cores each.
A Juniper EX2200 switch to network the servers and storage together.
A Local Console Manager (LCM) with rackable keyboard, video, and mouse.
In this next example, the IBM team combined a BladeCenter S chassis that can hold six blade servers, with a Storwize V7000 Unified which offers FCP, iSCSI, FCoE, NFS, CIFS, HTTPS, SCP and FTP block and file protocols.
If those configurations are too small for your needs, consider the Flex System chassis or full PureFlex system frame. The rack-mountable 10U chassis can hold the Flex System V7000 and 10 compute notes. The PureFlex frame can hold up to four of these chasses.
IBM and I.R.I.S-ICT also had an IBM XIV Gen3 and a TS3500 Tape library on display.
Continuing my coverage of the IT Security and Storage Expo in Brussels, Belgium, here is my post on the presentations I gave during the week.
There were four presentations each day. Of the five rooms, I was assigned one room in which to give all of my presentations, room 3. My room was quite large, with sixty seats.
It is a good idea for public speakers to understand Dutch, French, German and English in Belgium. In recognition of the fact that Belgians are multi-lingual, I started each session with "Goede Middag, Bon Jour and Good Afternoon!" and ended each with "Dank U, Merci and Thank you for attending!"

The sessions were all half-hour slots. The only presentation that I had a challenge getting down to 30 minutes was my session on "New Generation of Storage Tiering" in which I was asked to cover Easy Tier sub-LUN automated tiering, Server-to-Storage cooperative caching, Texas Memory Systems, hierarchical storage Management (HSM), Active Cloud Engine, and SmartCloud Storage!
Helping me out were three local IBM interns. From left to right: Joelle, Clara and Bryan. I hadn't noticed that there were only short breaks between sessions, all of this time consumed with one-on-one discussions with clients, so the interns were kind enough to fetch me snacks and drinks.
Joelle and Bryan speak Dutch, which is similar to the local Flemish language. Clara speaks French, which came in handy for translations.
I would like to thank my room monitors: Jolijn, Ella and Chloe. All three are local college students hired by the conference for the two days to scan name badges and count bodies in seats.
(I had to ask Jolijn to write her name on a piece of paper because it is Dutch and I had no clue how to spell it for this blog post.)
While it might appear that room 3 was "The Tony Pearson Show -- all Tony, all the time!" there were actually worthwhile sessions in the other rooms. Fellow blogger Jon Toigo [known for his DrunkenData blog] presented "Storage Infrastruggle 2013 -- Containing Storage Costs without Sacrificing Access, Protection or Management". My IBM colleague Ron Riffe presented a vendor-neutral look at Storage Hypervisors.
If the attendees wanted copies of my presentations, they were directed to get their name badge scanned at the IBM and I.R.I.S-ICT booth, all the way at the other end of the hall, and my presentations would be emailed to them.
(For those who have missed it, you can find all five of my presentations uploaded to the [IBM Expert Network] on Slideshare.)
Finally, I would like to thank my IBM colleagues who helped me develop and review my presentations: Brigitte Van Den Eynde, Joe Hayward, Jeff Jonas, Tom Deutsch, Chris Saul, Marisol Diaz, Iliana Garcia, Harley Puckett, Jack Arnold, and Steve McKinney.
The Belgium IT Security and Storage Expo was a great success!
(I am back to the USA in Portland, Oregon this week, so these posts relate to last week.)
However, that wasn't to say I didn't encounter a few challenges during my week in Belgium. The first was getting to the venue. The Belgium Expo is a large complex of buildings to the north of the city. The local IBM team suggested I go to the facility a day in advance so that I would be able to see where it was and how to get there.
I was staying in the center of town, in Place Rogier section. I had many transportation options:
Take a taxi. It was raining this week, so finding a taxi was difficult.
Take the bus. The Bus #260 goes directly from my hotel to the Belgium Expo, but only goes once an hour.
Take the metro. The metro operates frequently, and the Haysel stop is right in front of the Belgium Expo complex.
Upon arrival to the building complex, I was unsure of which building I needed to be in. Standing in front of the beautiful Building 5, I found this legend that provided the answer: Building 8. In front of Building 12 was a map that showed where Building 8 was located on the campus.
For this event, IBM joined forces with IBM Business Partner I.R.I.S-ICT to have a fabulous booth, with plenty of experts and equipment demos. As is often the case, the team had to work late into the night to get all the equipment set up, all the podiums and counters constructed, and the demos fully operational.
Apparently, I was not the only one to have troubles finding the place, so I did not feel alone. Some with cars drove around the complex several times before figuring out which parking lot to park in. Others parked at the first spot they found, and still ended up walking as much as I did.
For future reference, If you plan to attend any event at the Belgium Expo, either (a) ask for more explicit directions, and (b) plan to do lots of walking!
Well, I am back safely from my trip last week to Chicago, and now I am writing this in Madrid, Spain, on my way to Brussels, Belgium for the IT Storage Expo.
For those who have asked how the construction on the new Tucson EBC is going, here are a few pictures I took on Friday. As you can see, it is coming along nicely. The official grand opening will be April 2.
Did you miss IBM Pulse 2013 this week? I wasn't there either, having scheduled visits with clients in Washington DC this week, only to have those meetings cancelled due to the [U.S. sequestration cuts].
Fortunately, there are plenty of videos and materials to review from the event. Here's a [12-minute video] interview between Laura DuBois, Program VP of Storage for industry analyst firm [IDC], and fellow IBM executive Steve "Woj" Wojtowecz, VP of Tivoli Storage and Networking Software.
(Update: Apparently, IBM had not secured re-distribution rights from IDC to post this video prior to my blog post. IBM now has full permission to distribute. My apologies for any inconvenience last week.)
The two discuss client opportunities and requirements for storage clouds and compute clouds. Client cloud storage requirements include backup and archive clouds, file storage clouds, and storage that supports compute cloud environments.
Here are some upcoming events related to IBM Storage!
If you sell IBM and/or Oracle solutions, please join me for IBM Oracle Virtual University 2013!
A few weeks ago, I recorded a session on IBM Storage: Overview, Positioning and How to Sell that will be available on demand starting tomorrow, February 26th, at the IBM Oracle Virtual University 2013.
It's one of 65 new sessions that will help IBM to surround Oracle applications with IBM infrastructure, services and industry solutions. Oracle software, after all, runs best on IBM hardware. Other highlights of Oracle Virtual University include a live executive State of the Alliance session with Q&A, Oracle keynote, updates by Oracle product managers, sessions on PureSystems, Selling IBM into an Oracle environment, Cloud, and much more.
There will be live technical teams on hand throughout launch day to answer your questions in real time, so I hope you can carve out 30 minutes or more on February 26th to take advantage of these available resources.
After helping launch the first Pulse back in 2008, I have sadly not been back since. Last year, I was invited to attend as a last-minute replacement for another speaker, but I was busy [having emergency surgery].
This year's [Pulse 2013] conference looks amazing. It will be held in Las Vegas, Nevada. Guest Speaker Payton Manning, NFL 4-time MVP football player, and Carrie Underwood, 6-time Grammy award winner, join IBM's Software Group executives and experts on how IBM Tivoli can help optimize your IT infrastructure.
Sadly, once again, I will not be there at Pulse. This time, I will be on the East Coast visiting clients instead, but my on-premise correspondent, Tom Rauchut, has informed me that he will be there. Hopefully, he will provide me something to write about.
Later in March, I will be in Brussels, Belgium for the Storage Expo. This is held March 20-21, at the Brussels-Expo venue. I will be presenting several topics each day, as well as visit clients in the area. This event comes on behalf of IBM Belgium in association with IBM Business Partner IRIS-ICT.
If you plan to participate in any of these events, let me know!
Sadly, only 70 percent of doctors in the United States use Electronic Medical Record [EMR] systems. My own Primary Care Physician has made the switch, and told me he how much he loves having ready access to the information he needs. EMR systems reduce costs, help manage risk, and improve healthcare outcomes. It is no surprise that the U.S. government has taken a [stick-and-carrot approach] to encourage doctors to use them.
A frequent topic at the Tucson Executive Briefing Center where I work is how to make the most use of IT for healthcare and life sciences. For much of 2011 and 2012, I was also one of the technical advocates assigned to Wellpoint Insurance, in support of their adoption of IBM Watson technology for healthcare.
Recently, I spoke with Jarrett Potts, my long-time friend and former IBM colleague, who now works as Director of Strategic Marketing over at STORServer. If you have never heard of STORServer, it is a company that makes purpose-built backup appliances.
What is a Backup Appliance? It is an integrated solution of hardware and software that serves a single purpose: backup and recovery. STORServer Enterprise Backup Appliance (EBA) combines IBM's high-end x86 M4 server, IBM disk and tape storage, and IBM Tivoli Storage Manager (TSM) backup software.
(Fun Fact: The 2012 IBM year-end financial results were announced last month. IBM not only continues its #1 lead in servers overall, but has the #1 marketshare for high-end x86 servers, market-leading disk and tape storage hardware, and market leading backup software.)
To determine the appropriate size of your backup appliance, the folks at STORServer help you every step of the way. They figure out the number of TB you will backup every day, and even help configure all of the TSM server parameters to achieve the policies that make the most sense for your organization.
The appliance can backup every type of data, from databases and Virtual Machines (VMs) to documents, spreadsheets, and other unstructured data.
Are you then left with a solution too complicated to run yourself? No. The STORServer Console is an easy-to-use GUI for ongoing monitoring and maintenance. Plus, your friends at STORServer are only a phone call away in case you have any questions.
(FTC Disclosure: I work for IBM, and STORSever is an approved IBM Business Partner that uses IBM hardware and software to build their solution. I have no financial interest in STORServer, and was not paid by STORServer to mention their company or products on my blog. This post may be considered a celebrity endorsement of STORServer and its Enterprise Backup Appliances.)
Perhaps my readers feel that I am a bit biased in describing a TSM-based solution, and you want a second opinion. No worries, I understand. In the latest 165-page [2012 DCIG Backup Appliance Buyer's Guide], the STORServer models ranked very high. Here is an excerpt:
"Nowhere is this demand for purpose built appliances more evident than in the rise of purpose
built backup appliances (PBBAs) over the last few years and their anticipated growth rate
going forward. A recent market analysis performed by IDC found that worldwide PBBA revenue totaled $2.4 billion in 2011 which was a 42.4 percent increase over the prior year.
This scoring came into play in preparing this Buyer's Guide
as the STORServer EBA 3100 model scored so highly
overall that it fell outside of the two (2) standard deviations
that DCIG generally uses as a guideline for inclusion and
exclusion of products.
The reason DCIG included this model in this Buyer's Guide
whereas in other situations it might not is that DCIG is
unaware of any other backup appliance(s) from any other
providers that come close to matching the EBA 3100's
software and hardware attributes. As such, DCIG felt it
would be doing STORServer specifically and the market
generally a disservice by not highlighting in this Buyer's
Guide that such a backup appliance existed and was
generally available for purchase."
Backup Appliance Models
STORServer EBA 3100
Symantec NetBackup 5220 Backup Appliance
STORServer EBA 2100
STORServer EBA 1100
STORServer EBA 800
Symantec Backup Exec 3600 Appliance
The STORServer is ideal for small and medium-sized business (SMB), but can scale quite large to handle business growth. If you are currently unhappy with your current backup environment, and feel now is the time to look around for a better way of taking backups, you won't go wrong choosing a solution based on IBM's market-leading server and storage hardware with Tivoli Storage Manager software.
Well, it was Tuesday again, and we had quite a lot of announcements here at IBM this week!
Over 1,800 clients attended the [Live February 5 webcast]! The announcements were all part of IBM's SmartCloud Storage portfolio. Here are the highlights:
STN7800 Real-time Compression Appliance
Back in October 2010, IBM announced the acquisition of Storwize, Inc., renaming its NAS-compression units to the IBM Real-time Compression appliances. Some folks were confused, so I had a blog post [IBM Storwize Product Name Decoder Ring].
IBM initially offered two models:
The [STN6500 model] had 16 Ethernet ports 1GbE (16x1GbE) and a pair of four-core processors.
The [STN6800 model] had either eight 10GbE ports (8x10GbE), or four 10GbE plus eight 1GbE ports (4x10GbE+8x1GbE). It has a pair of six-core processors.
Now, IBM offers the [STN7800 model], which can replace either of the ones above, offering 16x1GbE, 8x10GbE, and 4x10GbE+8x1GBE port configurations. It has a pair of eight-core processors to handle more robust Cloud Storage environments. See [Announcement Letter 113-012] for more details.
New XIV Gen3 model 214
With its awesome support for VMware, the XIV is often chosen for Cloud storage. The new XIV model 214 now offers up to a dozen 10GbE ports, or you can stay with the 22 1GbE ports available on previous models. These can be used for iSCSI host attachment and/or IP-based replication.
IBM strives to make each new model of every storage device more energy efficient than the last.
The new XIV model is no exception. The original XIV, introduced in 2008, consumed 8.4 kVA fully loaded. The XIV Gen 3 model 114 consumed 7.0 kVA. This new model 214 consumes only 5.9 kVA!
It has been almost three years since my now infamous post [Double Drive Failure Debunked: XIV Two Years Later]. Back then, the XIV offered only 1TB and 2TB drives, with rebuild time for 1TB drive of less than 30 minutes, and for 2TB less than 60 minutes.
The new XIV Gen3 software 11.2 release, available for both the 114 and 214 models, can now rebuild a 2TB drive in less than 26 minutes, and a 3TB drive in less than 39 minutes. There is also support specific to Windows Server 2012 including thin provisioning, MSCS, VSS, and Hyper-V. See [Announcement Letter 113-013] for more details.
SmartCloud Storage Access
IBM is the first major storage vendor to offer a product of this kind, so understanding it may be a bit difficult.
The concept is simple. Rather than having end-users having to ask IT every time they need some storage space, IBM created a self-service portal that frees up the IT department to work on more important transformational projects.
This is basically what people can do with "Public Cloud" storage service providers, so basically IBM is now giving you the capability with your "Private Cloud" storage deployment.
Here is the sequence of events. End users point their favorite web browser to the self-service portal, and login using their credentials stored in your Active Directory or LDAP server database.
Once validated, the end-user now can request new storage space, expanding their existing space, or returning the space to the IT department. For new storage requests, users can have a choice of storage classes, -- such as Gold, Silver and Bronze-- defined in the Tivoli Storage Productivity Center (TPC), either stand-alone or in the SmartCloud Virtual Storage Center.
But wait! Do you want to give every end-user a blank check to provision their own storage? Most IT staff are horrified at the thought.
Knowing this, IBM has included an option to put in an approval process, based on the end-user and the amount of capacity requested. The approver can be the cloud administrator, or someone delegated for approvals, known as an environment owner.
For some users, policies may restrict the storage classes as well. For example, Fred can only have Silver or Bronze, but not Gold.
Once the approval is obtained, TPC then issues the appropriate commands to the appropriate SONAS or Storwize V7000 Unified device. SmartCloud Storage Access can do this for thousands of storage devices across dozens of geographically dispersed locations.
Before, the Cloud Admin had to configure storage pools of managed disks, define file systems, dole out file sets to hundreds or thousands of users with hard quotas, and then configure shares based on the protocols required, like CIFS, NFS, HTTPS, etc.
With SmartCloud Storage Access, the Cloud admin still defines the pools and file systems, but then lets the self-service capability of the software to create the file sets, set the quotas and configure shares with the appropriate protocols. This greatly reduces the work on the IT staff, and greatly improves the turn-around time for end-user requests to get exactly what they want, when they need it.
The next time you withdraw money from an ATM machine, fill up your gas tank at the self-service gas station, then serve your own salad at the salad bar and fill up your own soft drink at the fast food restaurant, you will realize and appreciate that SmartCloud Storage Access is a brilliant move for the IT staff.
Cloud administrators, environment owners, and end-users can all use SmartCloud Storage Access to monitor and report on storage usage.
(What does this have to do with Storage? When IBM got back into networking in a big way, they had to decide whether to combine it with one of the existing groups, or form its own group. IBM decided to merge networking with storage, which makes sense since the primary purpose of most networks is to access or transmit information stored somewhere else.)
Last April, the Wharton School and the Institute for the Future convened a one-day [After Broadband] workshop in San Francisco, California, that brought together a group of leading technologists, entrepreneurs, academics and policymakers to explore the future of broadband over the next decade.
Today is the last day of 2012, so it is only fitting to end the year looking forward to the future!
While I have been accused of being a historian, I consider myself a bit of a futurist. Since 2006, I have been blogging about the future of technology, including Cloud, Big Data, and the explosion of information. As a consultant for the IBM Executive Briefing Center, I present to clients IBM's future plans, strategies, and product roadmaps.
(Fellow blogger Mark Twomey on his Storagezilla blog has a humorous post titled [Stuff your Predictions], expressing his disdain for articles this time of year that predict what the next 12 months will bring. Don't worry, this is not one of those posts!)
What exactly is a futurist? Biologists study biology. Techologists study technology. But a person can't simply time-travel to the future, read the newspaper, make observations, take notes, and then go back in time to share his findings.
Here seem to be the key differences between Historians vs. Futurists:
There is only one past.
There are many possible futures.
Only six percent of humanity are alive today, so historians must study history through the writings, tools, and remains of those that have passed on.
Futurists study the past and the present, looking for patterns and trends.
Search for insight.
Search for foresight.
Framework to explain what happened and why.
Framework to express what is possible, probable, and perhaps even preferable.
A common framework for both is the concept of the various "Ages" that humanity has been through:
Around 200,000 years ago, in the middle of what archaeologists refer to as the [Paleolithic Era], man walked upright and used tools made of stone to hunt and gather food. Humans were nomadic and travelled in tribes to follow the herds of animals as they migrated season to season. The History Channel had a great eight-hour series called [Mankind: The Story of All of Us] that started here, and worked all the way up to modern times.
About 10,000 years ago, humans got tired of chasing after their meals, and settled down, growing their food instead. Grains like wheat, rice, and corn became staples of most diets around the world. Civilization evolved, and people traded what they grew or made in exchange for items they needed or wanted.
About 300 years ago, humans developed machines to help do things, and even to help build other machines. While farmers harnessed oxen to plow fields, and horses to speed up travel and communication, these were all based on muscle power.
Machines like the steam engine were powered by coal, petroleum, or natural gas. Today, one gallon of gasoline can do the work of 600 man-hours of human muscle power, or [move a ton of freight 400 miles].
Cities grew up with skyscrapers of steel, connected by trains, planes and automobiles. Communications with the telegraph, telephone, radio and television replaced sending message on horseback.
The forces that drove humanity to the Industrial age clashed with the culture and identity established during the Agricultural age. I highly recommend futurist Thomas Friedman's book [The Lexus and the Olive Tree] that covers these conflicts.
When exactly did the Information age begin? Did it start with Guttenberg's muscle-powered [Printing Press] in the year 1450, or the first punched card in 1725?
Futurist [Alvin Toffler] published his book The Third Wave in 1980. He coined the phrase "Third Wave" to describe the transition from the Industrial age to the Information age.
While IBM mainframes were processing information in the 1950's, many people associate the Information Age with the IBM Personal Computer (1981) or the World Wide Web (1991). Over 100 years ago, IBM started out in the Industrial age, with business machines like meat scales and cheese slicers. IBM led the charge into the Information Age, and continues that leadership today.
In any case, value went from atoms to bits. Computers and mobile devices transfer bits of data, information and ideas, from nearly anyplace on the planet to another, in seconds.
Ideas and content are now king, rather than land, buildings, machines and raw materials of the Industrial age. In 1975, less than 20 percent of a business assets were intangible. By 2005, over 80 percent is.
While the Industrial age was dominated by left-brain thinking, the Information Age requires the creativity of right-brain thinking. I highly recommend Daniel Pink's book, [A Whole New Mind] that covers this in detail.
"The future is already here -- it's just not very evenly distributed!" -- William Gibson (1993)
The problem with looking back through history as a series of "Ages" is that they really didn't start and end on specific days. The Agricultural age didn't end on a particular Sunday evening, with the Industrial age starting up the following Monday morning.
There are still people on the planet today in the Stone age. On my last visit to Kenya, I met a nomadic tribe that still lives this way. Huts were temporarily constructed from sticks and mud, and abandoned when it was time to move on.
A short-sighted charity built a one-room school house for them, hoping to convince the tribe that staying in one place for education was more important than hunting and gathering food in a nomadic lifestyle. Some stayed and starved.
In the United States, about 2 percent of Americans grow food for the rest of us, with enough left over to make ethanol and give food aid to other countries.
Sadly, the Standard American Diet continues to be foods mostly processed from wheat, rice and corn, even though our human genetic make-up has not yet evolved from a "Paleolithic" mix of [meats, nuts and berries].
There are still people on the planet today in the Industrial age. American schools are still geared to teach children for Industrial age jobs, but still take "summer vacation" to work in the fields of the Agricultural age? Seth Godin's book [Stop Stealing Dreams] is a great read on what we should do about this.
Wrapping up my series on a [Laptop for Grandma], I finally have something that I think meets all of my requirements! Special thanks to Guidomar and the rest of my readers who sent in suggestions!
I could have called this series "The Good, the Bad, and the Ugly". The [Cloud-oriented choices] weren't bad per se, but expected persistent Internet connection. The [Low-RAM choices] were not ugly per se, but had limited application options. The ones below were good, in that they helped me decide what would be just right for grandma.
Linux Mint 9
One of my readers, Guidomar, suggested Linux Mint Xfce. At LinuxFest Northwest 2012, Bryan Lunduke indicated that [Linux Mint] is the fastest growing Linux in popularity. You can watch his 43-minute presentation of [Why Linux Sucks!] on YouTube.
The latest version is Mint 14, but that has grown so big it has to be installed on a DVD, as it will no longer fit on a 700MB CD-ROM. Since I don't have a DVD drive on this Thinkpad R31, I dropped down to the latest Gnome edition that did fit on a LiveCD, which was Mint 9.
(In retrospect, I could have used the [PLoP Boot Manager CD], and installed the latest Linux Mint 14 from USB memory stick! My concern was that if a distribution didn't fit on a CD-ROM, it was expecting a more modern computer overall, and thus would probably require more than 384MB or RAM as well.)
Linux Mint is actually a variant of Ubuntu, which means that it can tap into the thousands of applications already available. Mint 9 is based on Ubuntu 10.04 LTS.
One of the nice features of Linux Mint is that there are versions with full [Codecs] installed. A codec is a coder/decoder software routine that can convert a digital data stream or signal, such as for audio or video data. Many formats are proprietary, so codecs are generally not open source, and often not included in most Linux distros. They can be installed manually by the Linux administrator. Windows and Mac OS are commercially sold and don't have this problem, as Microsoft and Apple take care of all the licensing issues behind the scenes.
The installation went smooth. It would have gladly set up a dual-boot with Windows for me, but instead I opted to wipe the disk clean and install fresh for each Linux distribution I tried.
Running it was a different matter. The screen would go black and crash. There just wasn't enough memory.
Since [Peppermint OS] was partially based on Lubuntu, I thought I would give [Lubuntu 12.04] a try. The difference is that Peppermint OS is based on Xfce (as is Xubuntu), but Lubuntu claims to have a smaller memory footprint using Lightweight X11 Desktop Environment (LXDE). This version claims to run in 384MB, which is what I have on grandma's Thinkpad R31.
There are two installers. The main installer requires more than 512MB to run, so I used the alternate text-based Installer-only CD, which needs only 192MB.
The LXDE GUI is simple and straightforward. As with Peppermint OS, I did have to install the Codec plugins. However, the time-to-first-note was less than two minutes, so we can count this as a success!
Linux Mint 12 LXDE edition
Circling back to Linux Mint, I realized that my problem up above was chosing the wrong edition. Apparently, Linux Mint comes in various editions, the main edition I had selected was based on Gnome which requires at least 512MB of RAM.
Other editions are based on KDE, xFCE and LXDE. Linux Mint 9 LXDE requires only 192MB of RAM, and the newer Linux Mint 12 LXDE requires only 256MB. I choose the latter, and the install went pretty much the same as Mint and Lubuntu above.
The music player that comes pre-installed is called [Exaile], which supports playlists, audio CDs, and a variety of other modern features, so no reason to install Rhythmbox or anything else. Grandma can even rip her existing audio CDs to import her music into MP3 format. Time-to-first-note was about two minutes.
The best part: the OS only takes up about 4GB of disk, leaving about 15GB for MP3 music files!
Lubuntu and Linux Mint LXDE were similar, but I decided to go with the latter because I like that they do not force version upgrades. This is a philosophical difference. Ubuntu likes to keep everyone on the latest supported releases, so will often remind you its time to upgrade. Linux Mint prefers to take an if-it-aint-broke-don't-fix-it approach that will be less on-going maintenance for me.
A few finishing touches to make the system complete:
A nice wallpaper from [InterfaceLift]. This website has high-res photography that are just stunning.
Power management with screen-saver settings to a nice pink background with white snowflakes falling.
A small collection of her MP3 music pre-loaded so that she would have something to listen to while she learns how to rip CDs and copy over the rest of her music.
Icons on the main desktop for Exaile, My Computer, Home Directory, and the Welcome Screen.
Larger Font size, to make it easier to read.
Update settings that only look for levels "1" and "2". There are five levels, but "1" and "2" are considered the safest, tested versions. Also, an update is only done if it does not involve installing or removing other packages. This should offer some added stability.
I considered installing [ClamAV] for anti-virus protection, but since this laptop will not be connected to the Internet, I decided not to burn up CPU cycles. I also considered installing [Team Viewer] which would allow me remote access to her system if anything should every fail. However, since she does not have Wi-Fi at home, and lives only a few minutes across town, I decided to leave this off.
Once again, I want to thank all of my readers for their suggestions! I learned quite a lot on this journey, and am glad that I have something that I am proud to present to grandma: boots quickly enough, simple to use, and does not require on-going maintenance!
Continuing my series on a [Laptop for Grandma], I thought I would pursue some of the "low-RAM" operating system choices. Grandma's Thinkpad R31 has only 384MB of RAM.
All of the ones below are based on Linux. For those who aren't familiar with installing or running the Linux operating system, here are some helpful tips:
Most Linux distributors allow you to download an ISO file for free. These can be either (a) burned to a CD, (b) burned to a DVD, or (c) written to a USB memory stick.
The ISO can be either a "LiveCD/LiveDVD" version, an installation program, or a combination of the two. The "Live" version allows you to boot up and try out the operating system without modifying the contents of your hard drive. Windows and Mac OS users can try out Linux without impact to their existing environment. Some Linux distributions offer both a full LiveCD+Installer version, as well as an alternate text-based Installer-only version. The latter often requires less RAM to use.
When installing, it is best to have the laptop plugged in to an electrical outlet, and hard-wired to the internet in case it needs to download the latest drivers for your particular hardware.
A CD can hold only 700MB. Many of the newer Linux distributions exceed that, requiring a DVD or USB stick instead. If your laptop has an older optical drive, it may not be able to read DVD media. Some older optical drives can only read CD's, not burn them. In my case, I burned the CDs on another machine, and then used them on grandma's Thinkpad R31.
To avoid burning "a set of coasters" when trying out multiple choices, consider using rewriteable optical media, or the USB option. If you don't like it, you can re-use for something else.
The program [Unetbootin] can take most ISO files and write them to a bootable USB stick. On my Red Hat Enterprise Linux 6 laptop, I had to also install p7zip and p7zip-plugins first.
The BIOS on some older machines, like my grandma's Thinkpad R31, cannot boot from USB. The [PLoP Boot Manager] allows you to first boot from floppy or CD-ROM, and then allows you to boot from the USB. This worked great on my grandma's system. The PLoP Boot Manager is also available on the [Ultimate Boot CD].
While I am a big fan of SUSE, Red Hat, and Ubuntu, these all require more RAM than available on grandma's laptop. Here are some Low-RAM alternatives I tried:
Damn Small Linux 4.11 RC2
The Damn Small Linux [DSL] project was dormant since 2008, but has a fresh new release for 2012. This baby can run in as little 16MB or RAM! If you have 128MB of RAM or more, the OS can run entirely from RAM, providing much faster performance.
Of course, there are always trade-offs, and in this case, apps were chosen for their size and memory footprint, not necessarily for their user-friendliness and eye candy. For example, the xMMS plays MP3 music, but I did not find it as friendly as iTunes or Rhythmbox.
Boot time is fast. From hitting the power-on button to playing the first note of MP3 music was about 1 minute.
Installing DSL Linux on the hard drive converts it into a Debian distribution, which then allows more options for applications.
Next up was [MacPup]. The latest version is 529, based on Pupply Linux 5.2.60 Precise, compatible with Ubuntu 12.04 Precise Pangolin. While traditional Puppy Linux clutters the screen with apps, the MacPup tries to have the look-and-feel of the MacOS by having a launcher tray at the bottom center of the screen.
Both MacPup and Puppy Linux can run in very small amounts of RAM and disk space. Like DSL above, you can opt to run MacPup entirely in 128MB of RAM. Unfortunately, the trade-off is a lack of application choices.
Installation to the hard drive was quite involved, certainly not for the beginner. First, you have to use Gparted to partition the disk. I created a 19GB (sda1) for my files, and 700MB (sda5) for swap. I had troubles with "ext4" file system, so re-formatted to "ext3". Second, you have to copy the files over from the LiveCD using the "Puppy Universal Installer". Third, you have to set up the Bootloader. Grub didn't work, so I installed Grub4Dos instead.
The music app is called "Alsa Player", and I was able to drag the icon into the startup tray. time-to-first-note was just over 1 minute. Fast, but not as "simple-to-use" as I would like.
SliTaz 4.0 claims to be able to run in as little as 48MB of RAM and 100MB of disk space. Time-to-first-note was similar to MacPup, but I didn't care for the TazPanel for setup, and the TazPkg for installing a limited set of software packages. I could not get Wi-Fi working at all on SliTaz, and just gave up trying.
All three of these ran on grandma's Thinkpad R31, and all three could play MP3 music. However, I was concerned that they were not as simple to use as grandma would like, and I would be concerned the amount of time and effort I might have to spend if things go wrong.
I've gotten suggestions to upgrade the memory and disk storage, and how to fine-tune the Microsoft Windows XP operating system. Others suggested replacing the OS with Linux, and to use the Cloud to avoid some of the storage space limitations.
But first, I have to mention the latest in our series of "Enterprise Systems" videos. The first was being [Data Ready]. The second was being [Security Ready]. The now the third in the series: the 3-minute
[Cloud Ready] video.
So I decided to try different Cloud-oriented Operating Systems, to see if any would be a good fit. Here is what I found:
(FTC Disclosure: I work for IBM and own IBM stock. This blog post is not meant to endorse one OS over another. I have financial interests in, and/or have friends and family who work at some of the various companies mentioned in this post. Some of these companies also have business relationships with IBM.)
Jolicloud and Joli OS 1.2
I gave this OS a try. This is based on Linux, but with an interesting approach. First, you have to be on-line all the time, and this OS is designed for 15-25 year-olds who are on social media websites like Facebook. By having a Jolicloud account, you can access this from any browser on any system, or run the Joli OS operating system, or buy the already pre-installed Jolibook netbook computer.
The Joli OS 1.2 LiveCD ran fine on my T410 with 4GB or RAM, giving me a chance to check it out, but sadly did not run on grandma's Thinkpad R31 with 384MB of RAM. According to the [Jolicloud specifications], Joli OS should run in as little as 384MB of RAM and 2GB of disk storage space, but it didn't for me.
Google Chrome and Chromium OS Vanilla
Like the Jolibook, Google has come out with a $249 Chromebook laptop that runs their "Chrome OS". This is only available via OEM install on desginated hardware, but the open source version is available called Chromium OS. These are also based on Linux.
Rather than compiling from source, Hexxeh has made nightly builds available. You can download [Chromium OS Vanilla] zip file, unzip the image file, and copy it to a 4GB USB memory stick. The compressed image is about 300MB, but uncompressed about 2.5GB, so too big to fit on a CD. The image on the USB stick is actually two partitions, and cannot be run from DVD either.
If you don't have a 4GB USB stick handy, and want to see what all the fuss is about, just install the Google Chrome browser on your Windows or Linux system, and then maximize the browser window. That's it. That is basically what Chromium OS is all about.
Files can be stored locally, or out on your Google Drive. Documents can be edited using "Google Docs" in the Cloud. You can run in "off-line" mode, for example, read your Gmail notes when not connected to the Internet. Music and video files can be played using the "Files" app.
If you really need to get out of the browser, you can hit the right combination of keys to get to the "crosh" command line shell.
Like Joli OS, I was able to run this from my Thinkpad T410 with 4GB of RAM, but not on grandma's Thinkpad R31. It appears that Chromium requires at least 1GB of RAM to run properly.
Android for x86
While researching the Chromium OS, I found that there is an open source community porting [Android to the x86] platform. Android is based on Linux, and would allow your laptop or netbook to run very much like a smartphone or tablet. Most of the apps available to Android should work here as well.
Unfortunately, the project has focused only on selected hardware:
ASUS Eee PCs/Laptops
Viewsonic Viewpad 10
Dell Inspiron Mini Duo
Lenovo ThinkPad x61 Tablet
I tried running the Thinkpad x61 version on both my Thinkpad T410 and grandma's Thinkpad R31, but with no success.
Peppermint OS Three
Next up was Peppermint OS, which claims to be a blend of Linux Mint, Lubuntu, and Xfce, but with a "twist" of aspiring to be a Cloud-oriented OS.
Rather than traditional apps to write documents or maintain a calendar, this OS offers a "Single-Site Browser" (SSB) experience, where you can configure "apps" by pointing to their respective URL. For documents, launch GWoffice, the client for Google Docs. For calendar, launch Google Calendar.
Most Linux distros have both a number and a project name associated with them. For example, Ubuntu 10.04 LTS is known as "Lucid Lynx". The Peppermint OS team avoided this by just calling their latest version "Three" which serves as both its number and its name.
The browser is Chromium, similar to Google Chrome OS above, and uses the "DuckDuckGo" search engine. This is how the Peppermint OS folks make their money to defray the costs of this effort.
Peppermint OS claims to run in systems as little as 192MB or RAM, and only 4GB of disk space. The LiveCD ran well on both my Thinkpad T410, as well as grandma's Thinkpad R31. More importantly, when I installed on the hard drive, it ran well.
The music app "Guayadeque" that came pre-installed was awful. It couldn't play MP3 music out-of-the-box. I had to install the Codec plugins from various "ubuntu-restricted-extras" libraries. I also installed the music app "Rhythmbox", and that worked great. Time from power-on to first-note was less than 2 minutes! However, the problems with the Guayadeque gave me the impression this OS might not be ready for primetime.
I contacted grandma to ask if she has Wi-Fi in her home, and sure enough, she doesn't. Her PC upstairs is direct attached to the cable modem. So, while the Cloud suggestion was worthy of investigation, I will continue to pursue other options that do not require being connected. I certainly do not want to spend any time and effort getting Wi-Fi installed there.
Happy Winter Solstice everyone! The Mayan calendar flipped over yesterday, and everything continued as normal.
The next date to watch out for is ... drumroll please ... April 8, 2014. This is the date Microsoft has decided to [drop support for Windows XP].
While many large corporations are actively planning to get off Windows XP, there are still many homes and individuals that are running on this platform.
When [Windows XP] was introduced in 2001, it could support systems with as little as 64MB of RAM. Nowadays, the latest versions of Windows now requires a minimum of 1GB for 32-bit systems, with 2GB or 3GB recommended.
That leaves Windows XP users on older hardware few choices:
Continue to run Windows XP, but without support (and hope for the best)
Upgrade their hardware with more RAM (and possibly more disk space) needed to run a newer level of Windows
Install a different operating system like Linux
Put the hardware in the recycle bin, and buy a new computer
Here is a personal example. A long time ago, I gave my sister a Thinkpad R31 laptop so that she could work from home. When she got a newer one, she passed this down to her daughter for doing homework. When my neice got a newer one, she passed this old laptop to her grandma.
Grandma is fairly happy with her modern PC running Windows XP. She plays all kinds of games, scans photographs, sends emails, listens to music on iTunes, and even uses Skype to talk to relatives. Her problem is that this PC is located upstairs, in her bedroom, and she wanted something portable that she could play music downstairs when she is playing cards with her friends.
"Why not use the laptop you have?" I asked. Her response: "It runs very slow. Perhaps it has a virus. Can you fix that?" I was up for the challenge, so I agreed.
(The Challenge: Update the Thinkpad R31 so that grandma can simply turn it on, launch iTunes or similar application, and just press a "play" button to listen to her music. It will be plugged in to an electrical outlet wherever she takes it, and she already has her collection of MP3 music files. My hope is to have something that is (a) simple to use, (b) starts up quickly, and (c) will not require a lot of on-going maintenance issues.)
Here are the relevant specifications of the Thinkpad R31 laptop:
The system was pre-installed with Windows XP, but was terribly down-level. I updated to Windows XP SP3 level, downloaded the latest anti-virus signatures, and installed iTunes. A full scan found no viruses. All this software takes up 14GB, leaving less than 6GB for MP3 music files.
The time it took from hitting the "Power-on" button to hearing the first note of music was over 14 minutes! Unacceptable!
If you can suggest what my next steps should be, please comment below or send me an email!
Tomorrow, according to the [Mayan calendar], the end of the 5,125 year cycle rolls over, so it only makes sense to party like it's 1999!
Of course, if you were in the IT industry 13 years ago, you may remember similar hoopla around [Year 2000] when the Gregorian calendar rolled over from "99" to "00". Some of us were asked to work right up to the last day of 1999, and be on-call the first week of 2000, just in case! Tomorrow may prove to be more or less a repeat of that.
Fortunately, there was plenty of other reasons to celebrate these past few weeks.
Birthdays in December Party
The IBM Tucson employees and contractors of building 9070 got together for a combination party, celebrating both the end of 2012 and for three people with birthdays in December: my former manager Bill, my colleague Kris, and myself. Here is our birthday cake! Afterwards, we allVacation movie.
(Note: This was sponsored by my third-line manager, David Gelardi, who one way or another, is responsible for all the IBMers in this building. Thank you David! )
This will be the last year for us to do this, as we are planning to move over to join the employees of building 9032 next year!
IBM Club Event
The IBM Club had its final event at [Golf N' Stuff] family fun park. Over 700 IBM employees and their family members came to eat breakfast burritos and play miniature golf and other games. It had rained earlier in the morning, so the go-kart track was wet, and the staff were trying to dry with leaf blowers. The rest of the park was fully operational, and the weather cleared up nicely. Mo, Rafael and I played golf but the turf was still wet in a few spots. There were also video games, bumper boats, and batting cages.
IBM volunteers dressed up as fictional characters for the kids to take pictures with.
I was proud to be a member of the seven-person IBM Club board for 2012. When I was nominated, I didn't think I stood a chance to be elected, as I was running against five or six other well-qualified candidates, but somehow it happened. I am glad to have been part of the 19-year tradition of the IBM Club history.
(Note: I didn't campaign for this position, but many IBMers in Tucson knew that I had previously owned and managed Tucson Fun & Adventures that organized 15-25 events every month for hundreds of single adults in the Tucson area. This might have helped my chances for election a bit!)
Next year, the IBM Club transitions to the more-efficient "Club Central" model, which is both board-less and cash-less. Instead of a seven-person board organizing events that are fully-funded or partially-subsidized by IBM, events will now be organized by IBM volunteers who post the details on Facebook. All participants simply pay for the events they attend directly to the venue or facility involved.
While the National Aeronautics and Space Administration [NASA] has put out videos and press releases these past 10 days to assure us [there will be a 2013], this shouldn't stop anyone from having a good time! If you did anything special to celebrate the end of the Mayan Calendar, please comment below!
In my last blog post [Full Disk Encryption for Your Laptop] explained my decisions relating to Full-Disk Encryption (FDE) for my laptop. Wrapping up my week's theme of Full-Disk Encryption, I thought I would explain the steps involved to make it happen.
Last April, I switched from running Windows and Linux dual-boot, to one with Linux running as the primary operating system, and Windows running as a Linux KVM guest. I have Full Disk Encryption (FDE) implemented using Linux Unified Key Setup (LUKS).
Here were the steps involved for encrypting my Thinkpad T410:
Step 0: Backup my System
Long-time readers know how I feel about taking backups. In my blog post [Separating Programs from Data], I emphasized this by calling it "Step 0". I backed up my system three ways:
Backed up all of my documents and home user directory with IBM Tivoli Storage Manager.
Backed up all of my files, including programs, bookmarks and operating settings, to an external disk drive (I used rsync for this). If you have a lot of bookmarks on your browser, there are ways to dump these out to a file to load them back in the later step.
Backed up the entire hard drive using [Clonezilla].
Clonezilla allows me to do a "Bare Machine Recovery" of my laptop back to its original dual-boot state in less than an hour, in case I need to start all over again.
Step 1: Re-Partition the Drive
"Full Disk Encryption" is a slight misnomer. For external drives, like the Maxtor BlackArmor from Seagate (Thank you Allen!), there is a small unencrypted portion that contains the encryption/decryption software to access the rest of the drive. Internal boot drives for laptops work the same way. I created two partitions:
A small unencrypted partition (2 GB) to hold the Master Boot Record [MBR], Grand Unified Bootlloader [GRUB], and the /boot directory. Even though there is no sensitive information on this partition, it is still protected the "old way" with the hard-drive password in the BIOS.
The rest of the drive (318GB) will be one big encrypted Logical Volume Manager [LVM] container, often referred to as a "Physical Volume" in LVM terminology.
Having one big encrypted partition means I only have to enter my ridiculously-long encryption password once during boot-up.
Step 2: Create Logical Volumes in the LVM container
I create three logical volumes on the encrypted physical container: swap, slash (/) directory, and home (/home). Some might question the logic behind putting swap space on an encrypted container. In theory, swap could contain sensitive information after a system [hybernation]. I separated /home from slash(/) so that in the event I completely fill up my home directory, I can still boot up my system.
Step 3: Install Linux
Ideally, I would have lifted my Linux partition "as is" for the primary OS, and a Physical-to-Virtual [P2V] conversion of my Windows image for the guest VM. Ha! To get the encryption, it was a lot simpler to just install Linux from scratch, so I did that.
Step 4: Install Windows guest KVM image
The folks in our "Open Client for Linux" team made this step super-easy. Select Windows XP or Windows 7, and press the "Install" button. This is a fresh install of the Windows operating system onto a 30GB "raw" image file.
(Note: Since my Thinkpad T410 is Intel-based, I had to turn on the 'Intel (R) Virtualization Technology' option in the BIOS!)
There are only a few programs that I need to run on Windows, so I installed them here in this step.
Step 5: Set up File Sharing between Linux and Windows
In my dual-boot set up, I had a separate "D:" drive that I could access from either Windows or Linux, so that I would only have to store each file once. For this new configuration, all of my files will be in my home directory on Linux, and then shared to the Windows guest via CIFS protocol using [samba].
In theory, I can share any of my Linux directories using this approach, but I decide to only share my home directory. This way, any Windows viruses will not be able to touch my Linux operating system kernels, programs or settings. This makes for a more secure platform.
Step 6: Transfer all of my files back
Here I used the external drive from "Step 0" to bring my data back to my home directory. This was a good time to re-organize my directory folders and do some [Spring cleaning].
Step 7: Re-establish my backup routine
Previously in my dual-boot configuration, I was using the TSM backup/archive client on the Windows partition to backup my C: and D: drives. Occasionally I would tar a few of my Linux directories and storage the tarball on D: so that it got included in the backup process. With my new Linux-based system, I switched over to the Linux version of TSM client. I had to re-work the include/exclude list, as the files are different on Linux than Windows.
One of my problems with the dual-boot configuration was that I had to manually boot up in Windows to do the TSM backup, which was disruptive if I was using Linux. With this new scheme, I am always running Linux, and so can run the TSM client any time, 24x7. I made this even better by automatically scheduling the backup every Monday and Thursday at lunch time.
There is no Linux support for my Maxtor BlackArmor external USB drive, but it is simple enough to LUKS-encrypt any regular external USB drive, and rsync files over. In fact, I have a fully running (and encrypted) version of my Linux system that I can boot directly from a 32GB USB memory stick. It has everyting I need except Windows (the "raw" image file didn't fit.)
I can still use Clonezilla to make a "Bare Machine Recovery" version to restore from. However, with the LVM container encrypted, this renders the compression capability worthless, and so takes a lot longer and consumes over 300GB of space on my external disk drive.
Backing up my Windows guest VM is just a matter of copying the "raw" image file to another file for safe keeping. I do this monthly, and keep two previous generations in case I get hit with viruses or "Patch Tuesday" destroys my working Windows image. Each is 30GB in size, so it was a trade-off between the number of versions and the amount of space on my hard drive. TSM backup puts these onto a system far away, for added protection.
Step 8: Protect your Encryption setup
In addition to backing up your data, there are a few extra things to do for added protection:
Add a second passphrase. The first one is the ridiculously-long one you memorize faithfully to boot the system every morning. The second one is a ridiculously-longer one that you give to your boss or admin assistant in case you get hit by a bus. In the event that your boss or admin assistant leaves the company, you can easily disable this second passprhase without affecting your original.
Backup the crypt-header. This is the small section in front that contains your passphrases, so if it gets corrupted, you would not be able to access the rest of your data. Create a backup image file and store it on an encrypted USB memory stick or external drive.
If you are one of the lucky 70,000 IBM employees switching from Windows to Linux this year, Welcome!
Earlier this year, IBM mandated that every employee provided a laptop had to implement Full-Disk Encryption for their primary hard drive, and any other drive, internal or external, that contained sensitive information. An exception was granted to anyone who NEVER took their laptop out of the IBM building. At IBM Tucson, we have five buildings, so if you are in the habit of taking your laptop from one building to another, then encryption is required!
The need to secure the information on your laptop has existed ever since laptops were given to employees. In my blog post [Biggest Mistakes of 2006], I wrote the following:
"Laptops made the news this year in a variety of ways. #1 was exploding batteries, and #6 were the stolen laptops that exposed private personal information. Someone I know was listed in one of these stolen databases, so this last one hits close to home. Security is becoming a bigger issue now, and IBM was the first to deliver device-based encryption with the TS1120 enterprise tape drive."
Not surprisingly, IBM laptops are tracked and monitored. In my blog post [Using ILM to Save Trees], I wrote the following:
"Some assets might be declared a 'necessary evil' like laptops, but are tracked to the n'th degree to ensure they are not lost, stolen or taken out of the building. Other assets are declared "strategically important" but are readily discarded, or at least allowed to [walk out the door each evening]."
Unfortunately, dual-boot environments won't cut it for Full-Disk Encryption. For Windows users, IBM has chosen Pretty Good Privacy [PGP]. For Linux users, IBM has chosen Linux Unified Key Setup [LUKS]. PGP doesn't work with Linux, and LUKS doesn't work with Windows.
For those of us who may need access to both Operating Systems, we have to choose. Select one as the primary OS, and run the other as a guest virtual machine. I opted for Red Hat Enterprise Linux 6 as my primary, with LUKS encryption, and Linux KVM to run Windows as the guest.
I am not alone. While I chose the Linux method voluntarily, IBM has decided that 70,000 employees must also set up their systems this way, switching them from Windows to Linux by year end, but allowing them to run Windows as a KVM guest image if needed.
Let's take a look at the pros and cons:
LUKS allows for up to 8 passphrases, so you can give one to your boss, one to your admin assistant, and in the event they leave the company, you can disable their passphrase without impacting anyone else or having to memorize a new one. PGP on Windows supports only a single passphrase.
Linux is a rock-solid operating system. I found that Windows as a KVM guest runs better than running it natively in a dual-boot configuration.
Linux is more secure against viruses. Most viruses run only on Windows operating systems. The Windows guest is well isolated from the Linux operating system files. Recovering from an infected or corrupted Windows guest is merely re-cloning a new "raw" image file.
Linux has a vibrant community of support. I am very impressed that anytime I need help, I can find answers or assistance quickly from other Linux users. Linux is also supported by our help desk, although in my experience, not as well as the community offers.
Employees that work with multiple clients can have a separate Windows guest for each one, preventing any cross-contamination between systems.
Linux is different from Windows, and some learning curve may be required. Not everyone is happy with this change.
(I often joke that the only people who are comfortable with change are babies with soiled diapers and prisoners on death row!)
Implementation is a full re-install of Linux, followed by a fresh install of Windows.
Not all software required for our jobs at IBM runs on Linux, so a Windows guest VM is a necessity. If you thought Windows ran slowly on a fully-encrypted disk, imagine how much slower it runs as a VM guest with limited memory resources.
In theory, I could have tried the Windows/PGP method for a few weeks, then gone through the entire process to switch over to Linux/LUKS, and then draw my comparisons that way. Instead, I just chose the Linux/LUKS method, and am happy with my decision.
For the past three decades, IBM has offered security solutions to protect against unauthorized access. Let's take a look at three different approaches available today for the encryption of data.
Approach 1: Server-based
Server-based encryption has been around for a while. This can be implemented in the operating system itself, such as z/OS on the System z mainframe platform, or with an applicaiton, such as IBM Tivoli Storage Manager for backup and archive.
While this has the advantage that you can selectively encrypt individual files, data sets, or columns in databases, it has several drawbacks. First, you consume server resources to perform the encryption. Secondly, as I mention in the video above, if you only encrypt selected data, the data you forget to, or choose not to, encrypt may result in data exposure. Third, you have to manage your encryption keys on a server-by-server basis. Fourth, you need encryption capability in the operating system or application. And fifth, encrypting the data first will undermine any storage or network compression capability down-line.
Approach 2: Network-based
Network-based solutions perform the encryption between the server and the storage device. Last year, when I was in Auckland, New Zealand, I covered the IBM SAN32B-E4 switch in my presentation [Understanding IBM's Storage Encryption Options]. This switch receives data from the server, encrypts it, and sends it on down to the storage device.
This has several advantages over the server-based approach. First, we offload the server resources to the switch. Second, you can encrypt all the files on the volume. You can select which volumes get encrypted, so there is still the risk that you encrypt only some volumes, and not others, and accidently expose your data. Third, the SAN32B-E4 can centralized the encryption key management to the IBM Tivoli Key Lifecycle Manager (TKLM). This is also operating system and application agnostic. However, network-based encryption has the same problem of undermining any storage device compression capability, and often has a limit on the amount of data bandwidth it can process. The SAN32B-E4 can handle 48 GB/sec, with a turbo-mode option to double this to 96 GB/sec.
Approach 3: Device-based
Device-based solutions perform the encryption at the storage device itself. Back in 2006, IBM was the first to introduce this method on its [TS1120 tape drive]. Later, it was offered on Linear Tape Open (LTO-4) drives. IBM was also first to introduce Full Disk Encryption (FDE) on its IBM System Storage DS8000. See my blog post [1Q09 Disk Announcements] for details.
As with the network-based approach, the device-based method offloads server resources, allows you to encrypt all the files on each volume, can centrally manage all of your keys with TKLM, and is agnostic to operating system and application used. The device can compress the data first, then encrypt, resulting in fewer tape cartridges or less disk capacity consumed. IBM's device-based approach scales nicely. IBM has an encryption chip is placed in each tape drive or disk drive. No matter how many drives you have, you will have all the encryption horsepower you need to scale up.
Not all device-based solutions use an encryption chip per drive. Some of our competitors encrypt in the controller instead, which operates much like the network-based approach. As more and more disk drives are added to your storage system, the controller may get overwhelmed to perform the encryption.
The need for security grows every year. Enterprise Systems are Security-ready to protect your most mission critical application data.

I hope all of my American readers had a wonderful Thanksgiving holiday! The day after Thanksgiving is "Black Friday", the unofficial starting data for shopping for upcoming holiday presents and decorations. The Monday after that is now often referred to as "Cyber Monday", where many people purchase items on-line.
I thought this would be good time to promote my book series, Inside System Storage, Volumes I through V. These are available direct from my publisher, [Lulu], or from other on-line retailers.
The old adage "Never judge a book by its cover" often leads technical authors to select bland cover designs. I designed the cover art for the series to have a consistent look, but be unique enough to know each book is different. They all have a beige background with black text, three or four graphics representing the various storage themes du jour, and a color stripe spread diagonally across the spine.
Several readers have asked if there was any rhyme or reason for the color of each spine. One guessed it was based on the [electronic color code] used on resistors to mark their value. When I was getting my college degree in Electrical Engineering, the mnemonic "Better Be Right Or Your Great Big Venture Goes West" helped us remember the sequence: Black, Brown, Red, Orange, Yellow, Green, Blue, Violet, Grey and White.
I can assure everyone I was not that clever. Here, instead, is the story behind each color chosen:
Volume I: Green
I received a flyer from Barnes and Noble advertising various books on sale. One caught my eye, so I went to buy it, but forgot to bring the flyer with me. A young woman offered to help me find it, but I could not remember the title, nor the editor, but it had a green cover, and was a collection of the world's shortest stories, all exactly 55 words in length, all winners in some high school contest. She found the flyer, looked up the book, and directed me to the shelf. After several minutes of her scanning the shelf by author, I reached for it, saying, "Here it is, the green one. This shade of green will fit perfectly in my collection of green books!" As I stood in line, the young woman told her boss, "That guy buys green books!" The rest of the folks in line overheard her, and all started laughing at her gullibility.
Volume II: Orange
In late 2007, I was under NDA to review the acquisition of a company called XIV. I was disclosed on the innovative design of the storage system, so that I could blog about it when the announcement was formal. This box would have a distinctive orange stripe across the disks. The announcement launch was a big success. Since then, every time the storage sales team needed a boost in sales for the [IBM XIV Storage System], I would write another blog about the clever features and capabilities.
Volume III: Purple
In 1996, I joined a social club called "Mile High Adventures and Entertainment", headquartered in Denver, Colorado, with locations in Phoenix, Tucson, San Diego, Los Angeles and Portland, Oregon. It was a group for singles to meet each other through social activities and events. A year later, it colapsed under the weight of heavy radio advertising debt. The local staff bought out the membership list, and launched a new club, under the name Tucson Fun and Adventures. It was a big part of my social life.
However, as the owners dropped out, one to start a family, another to take care of her father after her mother passed away, I started 2009 as the majority owner. The economic recession took its toll. Members were not spending as much of their disposable income of fun and entertainment. We restructured the company, revamped the website, and adopted Purple as our official color. Our event coordinators all wore purple shirts, and carried purple clipboards. Despite this major transformation, I just did not have time to run this company while still working full-time at IBM, so I sold it at year end.
Volume IV: Blue
As I mentioned in my blog post [IBM Introduces a New Era of Computing], IBM launched [PureSystems], a new family of expert-integrated systems. Since Volume IV was going to publish shortly after this announcement, I decided on the color blue to match the new door covers on the racks they came in. In less than a year, IBM has already sold over 1,000 of these systems in over 40 different countries.
Volume V: Grey
Chosing a color to represent the IBM Watson computer proved quite a challenge. I finally decided on grey, to represent "grey matter", a phrase often used to refer to the human brain. I picked a shade of grey that complements the three graphics that represent last year's strategic storage marketing themes. My blog post [How to Build Your Own Watson Jr. in your Basement] continues to be one of my highest read posts.
If you were having trouble getting ideas for gifts this holiday season, hopefully, this post gave you five new ideas for your friends, family, coworkers and clients! They are all available in hardcover, paperback, and eBook (PDF) for viewing on desktops, laptops, tablets or smartphones.
Well, it's Tuesday again, and you know what that means! IBM announcements!
Today, I am in New York visiting clients. The weather is a lot nicer than I expected. Here is a picture of the Hudson River through some trees with leaves turning color. Something we don't see in Tucson! Our cactus and pine trees stay green year-round!
The announcements today center around the IBM PureSystems family of expert integrated systems. The PureFlex is based on Flex System components. The Flex System chassis is 10U high that hold 14 bays, consisting of 7 rows by 2 columns. Computer and Storage nodes fit in the front, and switches, fans and power supplies in the back. Here is a quick recap:
IBM Flex System Compute Nodes
The x220 Compute Node is a single-bay low-power 2-socket x86 server. The x440 Compute Node is a powerful double-bay (1 row, 2 columns). The p260 Compute Node is a single-bay server based on the latest POWER7+ CPU processor.
IBM Flex System Expansion Nodes
Do you remember those old movies where a motorcycle would have a sidecar that could hold another passenger, or extra cargo? IBM introduces "Expansion Nodes" for the x200 series single-bay Compute nodes. The idea here is that in a single column, you have one bay for the Compute node, and then on the side in the next bay (same column) you have an Expanions node. There are two choices:
Storage Expansion Node allows you to have eight additional drives
PCIe Expansion Node allows to to have four PCIe cards, which could include the SSD-based PCIe cards from IBM's recent acquisition, Texas Memory Systems.
There are times where one or two internal drives are just not enough storage for a single server, and these expanion nodes could just be the perfect solution for some use cases.
IBM Flex System V7000 Storage Node
I saved the best for last! The Flex System V7000 Storage Node is basically the IBM Storwize V7000 repackaged to fit into the Flex System chassis. This means that in the front of the chassis, the Flex System V7000 takes up four bays (2 rows by 2 columns). In the back of the chassis are the power supplies, fans and switches.
The new Flex System V7000 supports everything the Storwize V7000 does except the upgrade to "Unified" through file modules. For those who want to have Storwize V7000 Unified in their PureFlex systems, IBM will continue to offer the outside-the-chassis original Storwize V7000 that can have two file modules added for NFS, CIFS, HTTPS, FTP and SCP protocol support.
IBM Flex System Converged Network Switch
The Converged Network Switch provide Fibre Channel over Ethernet (FCoE) directly from the chassis. This eliminates the need for a separate "Top-of-Rack" switch, and allows the new Flex System V7000 Storage Node to externally virtualize FCoE-based disk arrays.
Patterns of Expertise for Infrastructure
The original patterns of expertise focused on the PureApplication Systems. Now IBM has added some for the Infrastructure on PureFlex systems.
IBM has sold over 1,000 Flex System and PureFlex systems, across 40 different countries around the world, since their introduction a few months ago in April! These latest enhancements will help solidify IBM's industry leadership,
Well, it's Tuesday again, and you know what that means! IBM Announcements!
Today also happens to be [Election Day] in the United States, and some have questioned IBM's logic of making major storage announcements on Election Day. During the campaigns, a major theme was to help Small and Medium size businesses, because these are the engines of economic growth and improved employment.
Hopefully, you all saw today's Launch Webcast on these announcements, but in case you missed it, waiting in line at the polling station to cast your vote, or caught without electricity or Internet access from [Superstorm Sandy], it is now available [On-Demand].
The 2U control enclosure can have up to four additional 2U expansion enclosures, for a maximum of 120 drives, or 180TB of raw disk capacity. Like the Storwize V7000, the Storwize V3700 supports a [large number of servers and operating systems.]
Many of the features you already know from the Storwize V7000 are carried forward:
1GbE iSCSI + 8GbFC
8GbFC, 10GbE iSCSI/FCoE, Statement of Direction for 6Gb SAS
8GB per canister
4GB per canister, upgradeable to 8GB
Up to 4 control enclosures in a clustered system, each with up to 9 expansion enclosures
Up to 4 expansion enclosures
Maximum Number of drives/TB
Up to 120 drives/180TB
RAID levels supported
GUI, CLI, SMI-S API
GUI, CLI, SMI-S API
Internal (included), external (optional)
Internal only (included)
Non-disruptive data migration
One-directional (migrate to Storwize V3700, included)
Statement of direction
Up to 256 targets (included)
Up to 64 targets (included) Statement of Direction for optional 2,040 targets
Metro Mirror and Global Mirror (optional)
Statement of Direction (optional)
The IBM Storwize V3700 is offered at attractive leasing options through IBM Global Financing.
IBM LTO-6 drives and midrange tape libraries
Last month, IBM's [Tape and Storage Hypervisor Announcements] included LTO-6 for the enterprise-class TS3500 tape library. Today, the LTO-6 support is complete with support for midrange tape drives and libraries.
There are two tape drive models. The TS2260 is based on the half-height drive, intended for occasional 9-to-5 usage. The TS2360 is based on the full-height drive, intended for 24x7 access. These drives can read LTO-4 and LTO-5 tape cartridge media, and can write LTO-5 cartridge media. The new LTO-6 tape cartridge media is expected to be available next month.
In addition to the IBM TS3500 Enterprise Tape Library, LTO-6 is now supported on all of the midrange tape libraries: TS2900, TS3100, TS3200 and TS3310.
IBM Linear Tape File System Library Edition V2.1.2
There are two levels of [Linear Tape File System], or LTFS for short. The first is the Single Drive Edition (LTFS-SDE), which allows you to attach an LTO-5, LTO-6 or TS1140 tape drive to a single workstation, and allow you to mount tape cartridges as easy as mounting USB memory sticks. This presents a full file system view that allows you to read, edit, create, and even drag-and-drop files to other file systems. The LTFS-SDE driver is available for Windows, Linux, and Mac OS.
The second is the Library Edition (LTFS-LE), which allows you to mount the entire tape library as a file system. Each tape cartridge in the library is presented as a subdirectory folder, that you can access like any file system on disk. This was only available for Linux systems, which could then export the files through NFS, FTP or HTTP protocols to other clients. Now, with release v2.1.2, LTFS-LE supports Windows servers, so that you can share the files with other clients through CIFS as well.
Wow! Since my last blog post on this, we have over 600 registrants!

New IBM PureData Systems help clients harness data for critical insights
Well it's Tuesday, and you know what that means! IBM Announcements! Actually, it is Wednesday, but I started writing this post yesterday, and had to do some additional research to finish.
This week, IBM introduced the newest member of the PureSystems family of expert integrated systems - IBM PureData System. The new systems are designed to help clients effectively harness the massive volume, variety and velocity of information being created every day. The result? They deliver critical insights to improve business results.
The new systems are available in three different models, each optimized specifically for different workloads.
PureData System for Transactions. Optimized for transactional processing workloads such as e-commerce and built to handle large volumes of transactions with flexibility, availability, scalability and integrity. Basically, this is IBM DB2 pureScale and InfoSphere Optim features running on Linux-x86 nodes. The system comes in small, medium and large tee-shirt sizes, and can support over 100 databases. If you have DB2 applications, these can work with PureData unchanged. If your applications are based on Oracle databases, these can work with minimal changes to use PureData systems.
PureData System for Analytics. Powered by Netezza technology, this data warehouse system features built-in database analytics to quickly explore and analyze large amounts of sturctured information. This is the beefed-up version of the Netezza TwinFin 1000. IBM DB2® Analytics Accelerator for z/OS® V3.1 (IDAA) supports both the new IBM PureData System for Analytics N1001 and existing IBM Netezza 1000 systems as accelerators.
PureData System for Operational Analytics. Capable of delivering actionable insights concurrently to more than 1,000 business operations, supporting real-time decision making for businesses. This is the follow-on product to the IBM Smart Analytics System 7700 based on POWER7 nodes. This uses IBM Storwize V7000 disk systems inside.
PureData System joins the PureSystems family which also includes the PureFlex System and PureApplication System, [both announced last April]. PureSystems provide built-in expertise, integration by design and simplification through the system lifecyle, helping businesses reduce complexity, accelerate value and improve IT economics.
In a related announcement, Andy Monshaw was recently named IBM General Manager, PureFlex. Some of you readers may remember that Andy Monshaw was previously the General Manager for IBM System Storage several years ago, and was my second line manager, and I am glad to welcome him back!
If you store your VMware bits on external SAN or NAS-based disk storage systems, this post is for you. The subject of the post, VM Volumes, is a potential storage management game changer!
Fellow blogger Stephen Foskett mentioned VM Volumes in his [Introducing VMware vSphere Storage Features] presentation at IBM Edge 2012 conference. His session on VMware's storage features included VMware APIs for Array Integration (VAAI), VMware Array Storage Awareness (VASA), vCenter plug-ins, and a new concept he called "vVol", now more formally known as VM Volumes. This post provides a follow-up to this, describing the VM Volumes concepts, architecture, and value proposition.
"VM Volumes" is a future architecture that VMware is developing in collaboration with IBM and other major storage system vendors. So far, very little information about VM Volumes has been released. At VMworld 2012 Barcelona, VMware highlights VM Volumes for the first time and IBM demonstrates VM Volumes with the IBM XIV Storage System (more about this demo below). VM Volumes is worth your attention -- when it becomes generally available, everyone using storage arrays will have to reconsider their storage management practices in a VMware environment -- no exaggeration!
But enough drama. What is this all about?
(Note: for the sake of clarity, this post refers to block storage only. However, the VM Volumes feature applies to NAS systems as well. Special thanks to Yossi Siles and the XIV development team for their help on this post!)
The VM Volumes concept is simple: VM disks are mapped directly to special volumes on a storage array system, as opposed to storing VMDK files on a vSphere datastore.
The following images illustrate the differences between the two storage management paradigms.
You may still be asking yourself: bottom line, how will I benefit from VM Volumes?
Well, take a VM snapshot for example. With VM Volumes, vSphere can simply offload the operation by invoking a hardware snapshot of the hardware volume. This has significant implications:
VM-Granularity: Only the right VMs are copied (with datastores, backing up or cloning individual-VM portions of hardware snapshot of a datastore would require more complex configuration, tools and work)
Hardware Offload: No ESXi server resources are consumed
XIV advantage: With XIV, snapshots consume no space upfront and are completed instantly.
Here's the first takeaway: With VM Volumes, advanced storage services (which cost a lot when you buy a storage array), will become available at an individual VM level. In a cloud world, this means that applications can be provisioned easily with advanced storage services, such as snapshots and mirroring.
Now, let's take a closer look at another relevant scenario where VM Volumes will make a lot of difference - provisioning an application with special mirroring requirements:
VM Volumes case: The application is ordered via the private cloud portal. The requestor checks a box requesting an asynchronous mirror. He changes the default RPO for his needs. When the request is submitted, the process wraps up automatically: Volumes are created on one of the storage arrays, configured with a mirror and RPO exactly as specified. A few minutes later, the requestor receives an automatic mail pointing to the application virtual machine.
Datastores case #1: As may be expected, a datastore that is mirrored with the special RPO does not exist. As a result, the automated workflow sets a pending status on the request, creates an urgent ticket to a VMware administrator and aborts. When the VMware admin handles that ticket, she re-assigns the ticket to the storage administrator, asking for a new volume which is mirrored with the special RPO, and mapped to the right ESXi cluster. The next day, the volume is created; the ticket is re-assigned to the storage admin, with the new LUN being pointed to. The VMware administrator follows and creates the datastore on top of it. Since the automated workflow was aborted, the admin re-assigns the ticket to the cloud administrator, who sometime later completes the application provisioning manually.
Datastores case #2: Luckily for the requestor, a datastore that is mirrored with the special RPO does exist. However, that particular datastore is consuming space from a high performance XIV Gen3 system with SSD caching, while the application does not require that level of performance, so the workflow requires a storage administrator approval. The approval is given to save time, but the storage administrator opens a ticket for himself to create a new volume on another array, as well as a follow-up ticket for the VMware admin to create a new datastore using the new volume and migrate the application to the other datastore. In this case, provisioning was relatively rapid, but required manual follow up, involving the two administrators.
Here's the second takeaway: With VM Volumes, management is simplified, and end-to-end automation is much more applicable. The reason is that there are no datastores. Datastores physically group VMs that may otherwise be totally unrelated, and require close coordination between storage and VMware administrators.
Now, the above mainly focuses on the VMware or cloud administrator perspective. How does VM Volumes impact storage management?
VM's are the new hosts: Today, storage administrators have visibility of physical hosts in their management environment. In a non-virtualized environment, this visibility is very helpful. The storage administrator knows exactly which applications in a data center are storage-provisioned or affected by storage management operations because the applications are running on well-known hosts. However, in virtualized environments the association of an application to a physical host is temporary. To keep at least the same level of visibility as in physical environments, VMs should become part of the storage management environment, like hosts. Hosts are still interesting, for example to manage physical storage mapping, but without VM visibility, storage administrators will know less about their operation than they are used to, or need to. VM Volumes enables such visibility, because volumes are provided to individual VMs. The XIV VM Volumes demonstration at VMworld Barcelona, although experimental, shows a view of VM volumes, in XIV's management GUI.
Here's a screenshot:
That's not all!
Storage Profiles and Storage Containers: A Storage Profile is a vSphere specification of a set of storage services. A storage profile can include properties like thin or thick provisioning, mirroring definition, snapshot policy, minimum IOPS, etc.
Storage administrators define a portfolio of supported storage services, maintained as a set of storage profiles, and published (via VASA integration) to vSphere.
VMware or cloud administrators define the required storage profiles for specific applications
VMware and storage administrators need to coordinate the typical storage requirements and the automatically-available storage services. When a request to provision an application is made, the associated storage profiles are matched against the published set of available storage profiles. The matching published profiles will be used to create volumes, which will be bound to the application VMs. All that will happen automatically.
Note that when a VM is created today, a datastore must be specified. With VM Volumes, a new management entity called Storage Container (also known as Capacity Pool) replaces the use of datastore as a management object. Each Storage Container exposes a subset of the available storage profiles, as appropriate. The storage container also has a capacity quota.
Here are some more takeaways:
New way to interface vSphere and storage management: Storage administrators structure and publish storage services to vSphere via storage profiles and storage containers.
Automated provisioning, out of the box: The provisioning process automatically matches application-required storage profiles against storage profiles available from the specified storage containers. There is no need to build custom scripts and custom processes to automate storage provisioning to applications
The XIV advantage:
XIV services are very simple to define and publish. The typical number of available storage profiles would be low. It would also be easy to define application storage profiles.
XIV provides consistent high performance, up to very high capacity utilization levels, without any maintenance. As a result, automated provisioning (which inherently implies less human attention) will not create an elevated risk of reduced performance.
Note: A storage vendor VASA provider is required to support VM Volumes, storage profiles, storage containers and automated provisioning. The IBM Storage VASA provider runs as a standalone service that needs to be deployed on a server.
To summarize the VM Volumes value proposition:
Streamline cloud operation by providing storage services at VM and application level, enabling end-to-end provisioning automation, and unifying VMware and storage administration around volumes and VMs.
Increase storage array ROI, improve vSphere scalability and response time, and reduce cloud provisioning lag, by offloading VM-level provisioning, failover, backup, storage migration, storage space recycling, monitoring, and more, to the storage array, using advanced storage operations such as mirroring and snapshots.
Simplify the adoption of VM Volumes using XIV, with smaller and simpler sets of storage profiles. Apply XIV's supreme fast cloning to individual VMs, and keep automation risks at bay with XIV's consistent high performance.
Until you can get your hands on a VM Volumes-capable environment, the VMware and IBM developer groups will be collaborating and working hard to realize this game-changing feature. The above information is definitely expected to trigger your questions or comments, and our development teams are eager to learn from them and respond. Enter your comments below, and I will try to answer them, and help shape the next post on this subject. There's much more to be told.
A lot was announced this week, so I decided to break it up into several separate posts. This is part 3 in my 3-part series, focusing on our Tivoli Storage products.
To read the rest of the series, see:
The latest release of FlashCopy Manager now supports NetApp and IBM N series storage devices. This provides application-aware snapshots, coordinated with applications like SAP, DB2 and Oracle.
FlashCopy Manager now integrates with Metro and Global Mirror capabilities, so that application-consistent copies are available at remote sites for disaster recovery, or to off-load the FlashCopy destination copy from disk to Tivoli Storage Manager storage pools.
Tivoli Storage Manager v6.4
IBM Tivoli Storage Manager is part of IBM's Unifed Recovery Management. Here are some highlights:
Enhanced Reporting. Cognos reporting to monitor backup and archive environments.
TSM for ERP. I remember when these were called "Tivoli Data Protection" modules. We still refer to them as "TDPs". The TSM for ERP provides backup capability for SAP environments, and this latest release adds support for in-memory SAP HANA databases.
TSM for Virtualization Environments IBM TSM is famous for its patented "Progressive Incremental Backup" which is far more efficient than full+incrementals or full+differentials. IBM now extends this method to VM images. With people consolidating more and more VMs onto fewer host servers, TSM-VE now offers multiple backup streams in parallel. TSM-VE can now take application-aware backups of Microsoft Exchange, SQL Server, and Active Directory running in VMs. TSM-VE will also support vApp and VM templates. If it takes you [a day and a half to build a VMware template], you would want to make sure all that work was backed up, right?
Enhanced Security. Complex password support and improved user authentication and management by integration with Lightweight Directory Access Protocol (LDAP)
A lot was announced yesterday, so I decided to break it up into several separate posts. This is part 2 in my 3-part series, focusing on: Storwize V7000 Unified, LTO-6 tape, and the SmartCloud Virtual Storage Center.
The Storwize V7000 Unified is a product that consists of a 2U-high Storwize V7000 control enclosure that provides block-based access, combined with two 2U-high File Modules that provide file-based NAS protocols: CIFS, NFS, HTTPS, SCP and FTP. The problem was that when it was introduced, it was based on Storwize V7000 v6.3, so when the Storwize V7000 v6.4 features were announced last June, they did not apply to the Storwize V7000 Unified.
That is all fixed now, so the Storwize V7000 Unified now supports the full v6.4 features, including Real-time Compression for both file and block-based access to primary data, and Fibre Channel over Ethernet (FCoE) for block access.
The two File Modules are no longer limited to a single Storwize V7000 control enclosure, you can now connect to up to four control enclosures clustered together. Combined with up to nine expansion enclosures for additional disk raises the total maximum to 960 drives.
If you don't already have an Active Directory or LDAP server, the Storwize V7000 Unified now offers an embedded LDAP server, for smaller deployments that want to reduce the number of servers they need to purchase for a complete solution.
Like the [IBM XIV Gen3 storage system], both the Storwize V7000 and V7000 Unified now also support the OpenStack Nova-volume interface.
Lastly, if you have a Storwize V7000 v6.4, you can upgrade it to a Storwize V7000 Unified by simply adding the two File Modules. This can be done in the field.
IBM LTO-6 for tape libraries and drives
IBM introduces the sixth generation of Linear Tape Open (LTO-6) drives, which can be used as stand-alone IBM TS1060 drives, or in IBM tape libraries. As with previous models of LTO, the LTO-6 can read two older generations (LTO-4 and LTO-5) tape media, and can write to previous generation (LTO-5) tape media. You can buy the LTO-6 drives now, and use the older media until LTO-6 tape cartridges are available (hopefully later this year!)
My friend, Brad Johns, from Brad Johns Consulting, has a great post on this [LTO-6 Announcement]. While you expect the new drives to be faster with a denser tape media format, the key advantage to the LTO-6 is that it improves the compression algorithm, from the previous 2:1 to the new 2.5:1 compression ratio:
Thus, with the improved compression, the LTO-6 is 40 percent faster, with double the tape cartridge density. This can reduce backup times by 30 percent, increase the amount of data that sits in your automated tape libraries, and reduce the courier costs sending tapes off-site.
IBM SmartCloud Virtual Storage Center v5.1
Last year, IBM coined the phrase "Storage Hypervisor" to refer to the underlying technology in the IBM SAN Volume Controller (SVC) and Storwize V7000 disk systems.
At the IBM Edge conference last June, my colleague Mike Griese presented [SmartCloud Virtual Storage Center]. Back then, it was a pilot program (beta test), and this week, IBM announces that it will be formally available as a product.
The idea was simple: take the basic storage hypervisor, and add the necessary software to make it a complete solution.
If all of your disk is currently virtualized behind IBM SAN Volume Controller (SVC), or you want to put all of your data behind SVC, then SmartCloud Virtual Storage Center is for you. Basically, for one per-TB price, you get all of the following:
The software features of SAN Volume Controller v6.4, including FlashCopy, Metro Mirror and Global Mirror.
The full advanced features of IBM Tivoli Storage Productivity Center v5.1, including the Storage Analytics Engine that does "Right-Tiering", recommending which LUNs should be moved entirely from one disk system to another, based on policies and access patterns.
IBM Tivoli Storage FlashCopy Manager v3.2 which manages FlashCopy with full coordination with applications, including Microsoft Exchange, SQL Server, DB2, Oracle, SAP, and VMware. This ensures that the FlashCopy destination copies are clean, eliminating the need to run backout or redo logs to correct any incomplete units of work.
If this combination sounds familiar, it was based on IBM's previous attempt called [Rapid Application Storage] which combined the Storwize V7000 with Tivoli Storage Productivity Center Midrange Edition and FlashCopy Manager.
The key difference is that SmartCloud VSC does not include the SVC hardware itself, you buy this separately. If you want Real-time Compression, that is charged separately for the subset of TB of the volumes that you select for compression.
Well it's Wednesday, and you know what that means... IBM Announcements.
(Normally, announcements are on Tuesdays, but we moved this one over to Wednesday to line up with our big launch event in Pinehurst, NC. )
A lot was announced today, so I decided to break it up into several separate posts. I will start with our Enterprise Systems: DS8870, TS7700 Release 3, and XIV Gen3.
Enterprise systems are the servers, storage and software at the core of an enterprise IT infrastructure. Enterprise systems enable a private cloud infrastructure at enterprise scale, with flexible service delivery models that provide dynamic efficiency for resource and workload management. They make sure critical data is always available across the enterprise, making it accessible in new ways so that actionable insights can be derived from advanced and operational analytics. They also provide ultimate security, ensuring the integrity of critical data while mitigating risk and providing assured compliance.
IBM System Storage DS8870® disk system
This new storage system is the next generation in IBM's DS8000 series, based on IBM's POWER7 chipset. Each CEC can have 2, 4, 8 or 16 cores. Like the DS8800, you can have a mix of 2.5-inch and 3.5-inch disk drives of different speeds and capacities, up to 1,536 drives in a four-frame configuration. The maximum cache is now 1TB usable. The combination of faster chipset and more cache can triple performance for some workloads!
All DS8870s ship standard with all Full Disk Encryption (FDE-capable) drives. The problem in the past was that people would buy DS8000 with non-FDE drives, and then later want to activate encryption, and discovered that they have to swap out their drives with those with the encryption chip built in. Now, all drives on the DS8870 will have the encryption chip. This also allows Easy Tier sub-volume automated tiering to move encrypted data between all media types.
Flash optimization with DS8000 Easy Tier can improve performance up to 3 times with 3% of data on solid-state storage. Easy Tier is easy to deploy and runs automatically.
Support of the American National Standards Institute's (ANSI) T10 Data Integrity Field (DIF) standard. This is a feature that the mainframe has had for years, and is now being extended to distributed operating systems. The concept is simple. When sending data between server and storage, generate a checksum at the source, and then validate the checksum at the target. When you write a block of data, the server generates the checksum, and the DS8870 validates the checksum on arrival. When you read the data back, the DS8870 generates the checksum, and the server validates it on arrival. This ensures that data was not corrupted in between. There is a great write-up on IBM developerWorks: [End-to-end data protection using T10 standard data integrity field].
Energy Efficient. The DS8870 consumes less energy than its predecessor, the DS8800. For example, a fully-configured four-frame DS8870 with 1,536 disk drives consumes only 23.2kW, compared to the same number of drives in a DS8800 consumed 26.3 kW. By comparison, the DS8700 with five frames and 1,024 drives consumed 29.2kW.
Support for new System z load balancing algorithm. System z Workload Manager now interacts with the DS8870 I/O Priority Manager to optimize designated Quality of Service (QoS) levels. We have also the fastest operational analytics solution with DB2 list Prefetch cache optimization with DS8870 High Performance FICON (zHPF) integration. This solution increases DB2 query performance up to 11 times with disk, and up to 60 times with solid-state drives (SSD). File scans are up to 30 percent faster using DS8870 zHPF support for sequential access methods (QSAM, BPAM, and BSAM).
VMware vStorage APIs for Array Integration (VAAI) support. Why should the IBM DS8800 series support VMware when IBM already offers great VMware support with SAN Volume Controller (SVC), Storwize V7000 and XIV storage sytsems? Good question. This was hotly debated between development and marketing. Several DS8000 customers have already added SVC to provide full VMware VAAI support. As a consultant, I am neither development nor marketing, but felt it necessary to weigh in on my opinion on this. The DS8000 is a consolidation platform. According to one analyst survey, 22 percent of companies run on a single disk platform, so for DS8000 to be the one, it needs to support VMware and exploit these special APIs.
Six Nines Availability. Critical enterprise systems need to deliver continuous data availability, or very close to it. IBM solutions can help deliver up to six “nines” of availability, or 99.9999 percent when combining DS8000 Metro Mirror and GDPS Hyperswap. That's less than 30 seconds of downtime per year.
The TS7700 Release 3 represents a refresh to our existing virtual tape libraries. These are mainframe-only, offered in two models: TS7720 is a disk-only device, and the TS7740 is a blended disk-and-tape solution.
Industry standard hardware encryption. This applies to user data stored on the TS7700 system cache (disk), and for data transferred between TS7700 systems. This is especially important for regulations, like Payment Card Industry Data Security Standard (PCI-DSS). In previous models, the data would not be encrypted until it was moved off disk and written to tape. Now, it is encrypted the minute in lands on the disk cache, and stays encrypted as it is replicated from one TS7700 to another in the grid.
Up to 4 Million logical volume capacity. This is twice the previous support.
More physical capacity for TS7720 systems. The maximum capacity for the disk-only model is raised from 440TB to 620TB, representing a 40 percent increase.
My latest book "Inside System Storage: Volume V" is now available!
I have published my fifth volume in my "Inside System Storage" series! Currently, it is only available in Paperback. My editor, Susan Pollard, is hoping to have the eBook and Hardcover versions ready for Cyber Monday. The foreword was written by my Dr. Sondra Ashmore.
You can order this, and all my other books, in all formats, directly from my [Author Spotlight] page. The paperback will also be available soon from other online booksellers, search for ISBN 978-1-300-26223-7.
Improved Scalability. A new Multi-system Manager (MSM) server reduces the operational complexity for large and multi-site XIV deployments. Previously, admins connected directly to XIV boxes. If you had 10 admins logged in, then every XIV box was managing 10 admin conversations. The new MSM acts as a go-between. The admins connect to the MSM, and the MSM connects to the XIV boxes. The MSM polls and caches the status of each XIV, greatly increasing the number of XIV boxes that an admin can manage.
Enhanced User Interface. A new Multi-system Manager server reduces the operational complexity for large and multi-site XIV deployments. We also added support for IPsec and US. Government (USGv6) certification for admistering the XIV over IPv6 networks. The XIV Mobile Dashboard app for iPhone and iPad is spiffed up. Finally, the GUI has been internationalized and translated to the Japanese language.
Enhanced Integration for Cloud. For OpenStack, XIV now offers a Nova-volume driver which provides persistent storage to OpenStack compute nodes. The Nova task force is now looking to move storage into its own project called Cinder. For VMware, XIV has full support for Site Recovery Manager (SRM) v4.1 and v5.0 releases. XIV now also supports the Microsoft System Center Virtual Machine Manager, which can manage Hyper-V, VMware and Citrix XenServer hypervisors.
Smaller entry point. The original XIV supported 1TB and 2TB drives, with the smallest offering being 27TB usable. When IBM introduced the XIV Gen3, the two choices were 2TB and 3TB disk drives. Unfortunately, this meant that the initial entry model was now 55TB in size, and each additional module would be more expensive as well. IBM is now going to offer 1TB support for XIV Gen3 for a lower price point, these are actually 2TB drives with half the capacity turned off.
The job is located in Tucson, Arizona, which is a great place to live! Tucson is the headquarters for IBM storage design and development, with the largest collection of engineers, software developers and testers. The IBM Tucson Executive Briefing Center is located on the [University of Arizona Science and Technology Park] campus that houses over 7,000 employees from 50 different companies.
What does the job entail?
Primarily, you will be developing, customizing and presenting Powerpoint presentations and live product demos. For some briefings, you will work with sales reps, IBM Business Partners, and clients to develop an agenda of topics to discuss. At times, the presentation may involve working to solve the client's problems, drawing on the whiteboard or flip charts to help capture the requirements and architect a solution.
Which products are we talking about?
The [IBM System Storage product line] includes solid-state drives (SSD), block and file-based disk systems, tape drives and libraries, storage virtualization, and storage management software.
Is there any opportunity for travel?
Most of the presentations will be performed in Tucson, either in person, by webcast or video conference call. Sometimes, this includes discussions over drinks, dinner or golfing. Occasionally, there will be travel to present at client locations, IBM branch offices, events or conferences. My manager estimates approximately 10 percent travel.
Is the pay based on a commission?
Absolutely not! We are consultants, not salespeople. To maintain our "trusted advisor" status, it is a flat salary, with possibility for year-end bonus based on how well our division does overall. This allows us to present and position all of the products fairly to the clients at briefings without bias. Our clients appreciate that! The job is considered pre-sales technical support.
Is training included?
Yes. Assuming you already have a strong background in storage hardware and software, and how these connect to SAN and LAN networks for a variety of operating systems like z/OS, AIX, Windows and Linux, there will be training for the latest updates and features of the IBM products throughout the year. Also, there will be professional training to build up your public speaking and meeting facilitation skills.
How do I apply?
If you are an American citizen, fluent in the English language, and have at least a Bachelor's Degree, go to the [IBM Employment website], look for "Storage Support Specialist" position using job code "STG-0524037" or "STG-0525309". IBM is committed to creating a diverse environment and is proud to be an equal opportunity employer. All qualified applicants will receive consideration for employment without regard to race, color, religion, gender, gender identity or expression, sexual orientation, national origin, genetics, disability, age, or veteran status.
Last year, the Austin Executive Briefing Center had a room full of experts to help customers learn about IBM hardware to run Oracle applications. This year, IBM is back in San Francisco, with subject matter experts representing Power Systems, System x servers, PureSystems, Storage and System z mainframes. If you are in San Francisco, consider taking 1-2 hours out of your schedule to speak to IBM experts. These are intended to answer the question: Why choose IBM for your Oracle (and other) workloads?
Event: IBM Mini-Briefings Location: San Francisco Marriott Marquis, 55 Fourth Street, very close to the Moscone Center Dates: Monday through Wednesday, October 1-3, 2012
Subject Matter Experts:
Pat O'Rourke, Austin Briefing Center, Power Systems
Dennis Wunder, Poughkeepsie Briefing Center, System z mainframes
Steve Loeschorn, Raleigh Briefing Center, System x servers
Curtis Neal, Tucson Briefing Center, Storage
IBM will also have a booth presence on the main Oracle OpenWorld showroom floor. Please stop by and visit my colleagues! To sign up for a Mini-Briefing at Oracle OpenWorld, for any or all of the topics above, visit the new [IBM STG Austin EBC] website.
Many thanks to the 186 people who registered for yesterday's webcast "Solving the Storage Capacity Crisis -- Tools and Practices for Effective Management!" We had some excellent questions posed during the live Q&A:
Do you recommend moving to a SAN before implementing the management techniques you described, or will these tactics work just as well on direct-attached storage?
How does data center tiering differ from hierarchical storage management?
How do you recommend decisions about data priority be made when there are multiple stakeholders competing for attention?
You didn't mention deduplication. Does that have much impact on capacity management?
When outsourcing to a storage service provider, do you have any recommendations of the merits of wholesale outsourcing vs. partial outsourcing?
What are the dangers of giving end-users the ability to manage their own storage? What kind of education should be put in place?
The webcast was recorded, so in case you missed it, or just want to hear it again, the recording is now available in the [On24 archives].
Now an avid reader of my blog has brought this to my attention. Apparently,
EMC has been showing customers a presentation
[Accelerating Storage Transformation with VMAX and VPLEX] with false and misleading comparison claims between IBM DS8000, HDS VSP and EMC VMAX 40K disk system performance.
(FTC Disclosure: This would be a good time to remind my readers that I work for IBM and own IBM stock. I do not endorse any of the EMC or HDS products mentioned in this post, and have no financial affiliation or investments directly with either EMC nor HDS. I am basing my information solely on the presentation posted on the internet and other sources publicly available, and not on any misrepresentations from EMC speakers at the various conferences where these charts might have been shown.)
The problem with misinformation is that it is not always obvious. The EMC presentation is quite pretty and professional-looking. It is the typical slick, attention-getting, low-content, over-simplified marketing puffery you have come to expect from EMC. There are two slides in particular that I have issue with.
This first graphic implies that IBM and HDS are nearly tied in performance, but that EMC VMAX 40K has nearly triple that bandwidth. Overall the slide has very little detail. That makes it difficult to determine what exactly is being claimed and whether a fair comparison is being made.
The title claims that VMAX 40K is "#1 in High Bandwidth Apps". Only three disk systems are shown so the claim appears to be relative to only the three systems. The wording "High Bandwidth Apps" is confusing considering the cited numbers are for disk systems and no application is identified. By comparison, IBM SONAS can drive up to 105 GB/sec sequential bandwidth, nearly double what EMC claims for its VMAX 40K, so EMC is certainly not even close to #1.
Is the workload random or sequential? That is not easy to determine. The use of "GB/s" along with the large block size of 128KB implies the I/O workload is sequential, which is great for some workloads like high performance computing, technical computing and video broadcasts. Random workloads, on the other hand, are usually measured in I/Os per second (IOPS) with a block size ranging 4KB to 64KB. (I am assuming the 128K blocks refers to 128KB block size, and not reading the same block of cache 128,000 times.)
The slide states "Maximum Sustainable RRH Bandwidth 128K Blocks". The acronym "RRH" is not defined; but I suspect this refers to "random read hits". For random workloads, 100 percent random read hits from cache represents one corner of the infamous "four corners" test. Real-world workloads have a mix of reads and writes, and a mix of cache hits and cache misses. It is also unclear whether the hits are from standard data cache or from internal buffers in adapters (perhaps accessing the same blocks repeatedly) or something else. So is this really for a random workload, or a sequential workload?
(The term "Hitachi Math" was coined by an EMC blogger precisely to slam Hitachi Data Systems for their blatant use of four-corners results, claiming that spouting ridiculously large, but equally unrealistic, 100 percent random read hit results don't provide any useful information. I agree. There are much better industry-standard benchmarks available, such as SPC-1 for random workloads, SPC-2 for sequential workloads, and even benchmarks for specific applications, that represent real-world IT environments. To shame HDS for their use of four-corners results, only for EMC themselves to use similar figures in their own presentation is truly hypocritical of them!)
The IBM system is identified as "DS8000". DS8000 is a generic family name that applies to multiple generations of systems first introduced in 2004. The specific model is not identified, but that is critical information. Is this a first generation DS8100, or the latest DS8800, or something in between?
The slide says "Full System Configs", but that is not defined and configuration details are not identified. Configuration details, also critical information in assessing system performance capabilities, are not specified. If the EMC box costs seven times more than IBM or HDS, would you really buy it to get 3x more performance? Is the EMC packed with the maximum amount of SSD? Were there any SSD in the IBM or HDS boxes to match?
The source of the claimed IBM DS8000 performance numbers is not identified. Did they run their own tests? While I cannot tell, the VMAX may have been configured with 64 Fibre Channel 8Gbps host connections. In that case each channel is theoretically capable of supporting about 800 MB/s at 100% channel utilization. Multiplying 64 x 800MB/s = 51.2GB/s, so did EMC just do the performance comparison on the back of a napkin, assuming there are no other bottlenecks in the system? Even then, I would not round up 51.2 to 52!
Response times were not identified. For random I/Os, response time is a very important metric. It is possible that the Symmetrix was operating with some resources at 100% utilization to get the highest GB/s result, but that would likely make I/O response times unacceptable for real-world random I/O workloads.
IBM and HDS have both published Storage Performance Council [SPC] industry-standard performance benchmarks. EMC has not published any SPC benchmarks for VMAX systems. If EMC is interested in providing customers with audited, detailed performance information along with detailed configuration information, all based on benchmarks designed to represent real-world workloads, EMC can always publish SPC benchmark results as IBM and other vendors have done. In past blog fights, EMC resorts to the excuse that SPC isn't perfect, but can they really argue that vague and unrealistic claims cited in its presentation are better?
The second graphic is so absurd, you would think it came directly from Larry Ellison at an Oracle OpenWorld keynote session. EMC is comparing a configuration with VMAX 40K plus an EMC VFCache host-side flash memory cache card to a configuration with an IBM and HDS disk system without host-side flash memory cache also configured. The comparison is clearly apples-to-oranges. Other disk system configuration details are also omitted.
FAST VP is EMC's name for its sub-volume drive tiering feature, comparable to IBM Easy Tier and Hitachi's Dynamic Tiering. The graph implies that IBM and HDS can only achieve a modest increment improvement from their sub-volume tiering. I beg to differ. I have seen various cases where a small amount of SSD on IBM DS8000 series can drastically improve performance 200 to 400 percent.
The "DBClassify" shown on the graph is a tool run as part of an EMC professional services offering called Database Performance Tiering Assessment, makes recommendations for storing various database objects on different drive tiers based on object usage and importance. Do you really need to pay for professional services? With IBM Easy Tier, you just turn it on, and it works. No analysis required, no tools, no professional services, and no additional charge!
VFCache is an optional product from EMC that currently has no integration whatsoever with VMAX. A fair comparison would have included a host-side flash memory cache (from any vendor) when the IBM or HDS storage system was configured. Or leave it out altogether and just focus on the sub-volume tiering comparison.
Keep in mind that EMC's VFCache supports only selected x86-based hosts. IBM has published a [Statement of Direction] indicating that it will also offer this for Power systems running AIX and Linux host-side flash memory cache integrated with DS8000 Easy Tier.
I feel EMC's claims about IBM DS8000 performance are vague and misleading. EMC appears to lack the kind of technical marketing integrity that IBM strives to attain.
Since EMC is not able or willing to publish fair and meaningful performance comparisons, it is up to me to set the record straight and point out EMC's failings in this matter.
Reminder: It's not to late to register for my Webcast "Solving the Storage Capacity Crisis" on Tuesday, September 25. See my blog post [Upcoming events in September] to register!
Can you believe it is September already? We have a number upcoming events that you might be interested in.
IBM Smarter Analytics by Design
Join the first of our 'Smarter Analytics by Design' virtual events to learn more from leading industry analyst IDC on how analytics can help you solve business challenges, and the capabilities you'll need to be successful in this ever-changing landscape. You'll also hear real case examples from AXTEL and Miami-Dade County and the results of their analytics approaches.
Webcast: IBM Smarter Analytics by Design Date: Thursday, September 13, 2012 Time: 1:00 pm ET / 12:00 pm CT / 10:00 am PT

The problems that used to keep storage managers awake at night -- power, cooling and physical footprint -- are being successfully addressed by technology, but a more vexing issue still remains: How to get more out of the limited supply of skilled storage management professionals.
Webcast: Solving the Storage Capacity Crisis Date: Tuesday, September 25, 2012 Time: 12:00 pm ET / 10:00 am CT / 09:00 am PT
Demand for storage capacity continues to grow far faster than the pool of people to manage it. With no end in sight to data growth, businesses need to apply technology and practices that distribute management responsibility to the people who need storage, and multiply the volumes of storage that skilled professionals can handle.
In this presentation, in this session, I will cover best practices and new tools that are enabling leaps in productivity, in three main areas:
IBM is bringing back and expanding its Mini Briefing program to Oracle OpenWorld.
What is a Mini-Briefing you might ask? It is a small, customized briefing by the Executive Briefing Centers, held nearby a related conference, allowing conference attendees to take 1-2 hours out of their schedule to speak to IBM experts. These are intended to answer the question: Why choose IBM for your Oracle (and other) workloads?
Event: IBM Mini-Briefings Location: San Francisco Marriott Marquis, 55 Fourth Street, very close to the Moscone Center Dates: Monday through Wednesday, October 1-3, 2012
Last year, the Austin Executive Briefing Center had a room full of experts to help customers learn about IBM hardware to run Oracle applications. This year, IBM is back in San Francisco, with subject matter experts representing Power Systems, System x servers, PureSystems, Storage and System z mainframes.

Of course, IBM will also have a booth presence on the main Oracle OpenWorld showroom floor. Sadly, I will not be there myself this year. Please stop by and visit my colleagues!
To sign up for a Mini-Briefing at Oracle OpenWorld, for any or all of the topics above, visit the new [IBM STG Austin EBC] website.
I hope you can participate in one or more of these events!
This month, I am pleased to announce the new [IBM STG Executive Briefing Center] website, representing a huge improvement over the previous website we had been using over the past two years. STG refers to IBM's Systems and Technology Group, the division that focuses on servers, storage, switches and the system software that makes them run. This new website is for the dozen STG EBCs that span the globe. The new website reminds me of this famous quote:
"Perfection is achieved, not when there is nothing left to add, but when there is nothing left to take away"
-- Antoine de Saint-Exupery
Let's take a quick look at what makes it so much better.
The previous website required registration. At every briefing, those of us who work in the EBCs had to pass around a sign-up sheet for email addresses from each attendee so that we could send them an invitation to register for the site. We would have a hard time reading people's handwriting, resulting in some emails coming back rejected.
Inspired by self-service gas stations, automated teller machines, and the many self-service portals of Cloud Computing, the new website has everything up-front, without registration. IBM Business Partners and sales representatives can easily request a briefing at any of the dozen briefing centers represented!
IBM-managed and IBM-hosted
We had a difficult time explaining to our attendees why our previous website was hosted on a lone machine and maintained by a third party. Think about it, IBM manages the data centers of over 400 clients. IBM has provided web hosting to the most mission critical workloads, with high levels of availability and reliability, and is recognized as one of the "Big 5" Cloud companies. I have done web design myself in my career, and we were terribly disappointed with the third party chosen to create and maintain our previous website, constantly having to point out errors in their HTML and CSS.
For the new website, IBM took back control. Staff from each EBC, myself included, came up with a simple page to bring the essence of each location to life. Special thanks to my colleage Hal Jennings, from the Austin EBC, for bringing this altogether!
Despite two years of manually registering attendees to use the previous website, Google Analytics showed that few people visited, and the few that did spent little time exploring the vast repository of content.
The new website is vastly simpler. The front page points to all twelve EBCs, and a single mouse click gets you to the location you are interested in, with all the details you need to make a decision to book a briefing, and the contact information to make it happen.
Elimination of Wasted and Duplicate Effort
In the previous website, we spent as much as 15 hours just to create, voice over, edit and produce a single 15-minute recorded presentation. Less than six percent of the previous website visitors watched more than five minutes of these videos, making us feel that most of our effort was wasted.
The EBC staff kept wasting their time, month after month, thanks to all-stick, no-carrot tactics that mandated minimums for contributions for more and more content that nobody was ever looking at. Even more disappointing was that much of our work duplicated the formal responsibilities of our IBM Marketing team. They weren't happy about this either, causing confusion between the roles of our two teams.
Finally, we said enough was enough! The new STG EBC website is a marvel in minimalism. If you want to see presentations, videos, expert profiles, or partake in on-going conversations, I welcome you to visit the [IBM Expert Network], the [IBM Storage YouTube Channel], and the [Storage Community] where they belong.
With all of the distractions this week, from the Republican National Convention in Florida, to the Tropical Storm Isaac that hit New Orleans on the 7th anniversary of Hurricane Katrina, I thought I would continue this week's theme on the IBM zEnterprise EC12.
Processing an insurance claim: $56 U.S. dollars (USD) with mainframes, versus $92 USD with distributed servers.
Processing a mobile subscriber: $18.26 USD with mainframes, versus $26.12 USD with distributed servers.
IT cost for an ATM machine: $572 USD with mainframes, versus $1021 USD with distributed servers.
In the whitepaper [Total Economic Impact of IBM System z], Forrester Research interviews the executives of five existing mainframe clients, and through in-depth analysis of their deployments, is able to present a "composite" company with an IT-staff of 4,500 employees. The result is impressive: deploying an IBM System z had an ROI of 199 percent. That is a payback period of less than five months!
A finish this post with a quick [6-minute Youtube video], featuring my colleage, Nick Sardino. Nick and I have worked together in the past at various conferences and conventions.
Well it's Tuesday again, and you know what that means! IBM Announcements!
For nearly 50 years, IBM has been leading the IT industry with its mainframe servers. Today, IBM announced its 12th generation mainframe in its [System z product family], the IBM zEnterprise EC12, or zEC12 for short. I joined IBM in 1986, and my first job was to work on DFHSM for the MVS operating system. The product is now known as DFSMShsm as part of the Data Facility Storage Management System, and the operating systems went through several name changes: MVS/ESA, OS/390, and lately z/OS. I was the lead architect for DFSMS up until 2001. I then switched to be part of the team that brought Linux to the mainframe. Both of these experiences come in handy as I deal with mainframe storage clients at the Tucson Executive Briefing Center.
Let's take a look at some recent developments over the past few years.
In the 9th and 10th generations (IBM System z9 and z10, respectively), IBM introduced the concept of a large "Enterprise Class", and a small "Business Class" to offer customer choice. These were referred to as the EC and BC models.
For the 12th generation, IBM kept the name "zEnterprise", but went back to the "EC" to refer to Enterprise Class. Rather than offer a separate "small" Business Class version, the zEC12 comes in 60 different sub-capacity levels. Many software vendors charge per core, or per [MIPS], so offering sub-capacity means that some portion of the processors are turned off, so the software license is lower. The top rating for the zEC12 is 78,000 MIPS. (I would have thought by now that we would have switched over to BIPS by now!)
If you currently have a z10 or z196, then it can be upgraded to zEC12. The zEC12 can attach to up to four zBX model 003 frames that can run AIX, Microsoft Windows and Linux-x86. If you currently have zBX model 002 frames, these can be upgraded to model 003.
The key enhancements reflect the three key initiatives:
Operational Analytics - Most analytics are done after-the-fact, but IBM zEnterprise can enable operational analytics in real-time, such as fraud detection while the person is using the credit card at a retail outlet, or online websites providing real-time suggestions for related products while the person is still adding items to their shopping card. Operational analytics provides not just the insight, but in a timely manner that makes it actionable. There is even work in place to [certify Hadoop on the mainframe].
Security and Resiliency - IBM is famous for having the most secure solutions. With industry-leading EAL5+ security rating, it beats out competitive offerings that are typically only EAL4 or lower. IBM has a Crypto Express4S card to provide tamper-proof co-processing for the system. IBM introduces the new "zAware" feature, which is like "Operational Analytics" pointed inward, evaluating all of the internal processes, error logs and traces, to determine if something needs to be fixed or optimized.
Cloud Agile - When people hear the phrase "Cloud Agile" they immeidately think of IBM System Storage, but servers can be Cloud Agile also, and the mainframe can run Linux and Java better, faster, and at a lower cost, than many competitve alternatives.
Earlier this week, Jon Erickson from Forrester Reserch, and Chris Saul from IBM, co-presented a webcast on the economic impact of using SAN Volume Controller for storage virtualization. The event was co-sponsored by IBM, InformationWeek, and UBM TechWeb, The Global Leader in Business Technology Media, a Division of UBM LLC. Jon spoke first, covering the cost savings and financial benefits of using SAN Volume Controller in your environment. His analysis shows a payback period of only 18 months!
Chris Saul (IBM) then covered the latest features introduced last June for SAN Volume Controller v6.4 release. Many of these features are available on older hardware models of SAN Volume Controller. One of the most exciting features is Real-time Compression.
If you missed the webcast, you can listen to the [Replay]. There is also a [whitepaper] if you prefer that format.
The Real-time Compression benefits can vary by the type of data compressed. Some data compresses only 20% savings. Other data compresses 80% or more. The best way to find out how much Compression would benefit your environment is to run the [IBM Comprestimator Tool] that runs against your own data!
If you are constantly battling out-of-space conditions, and would like to make extra room on your existing storage devices, your dreams have come true!
IBM has announced it has entered into a definitive agreement to acquire Texas Memory Systems, Inc. (TMS), a privately held Houston, Texas-based company with about 100 employees, that focuses on solid-state flash optimized systems and solutions, including the RamSan family of external rack-mounted storage, as well as PCIe cards for internal storage that fit inside servers.
I've mentioned Solid-State Drive storage quite a few times over the past few years in this blog, which included some great interactions with my friends over at Texas Memory Systems. Here's a quick look:
In my now infamous blog post [Hybrid, Solid State and the future of RAID], I resort to a deck of [Tarot cards] in an effort to fight [writer's block] responding to query about combining solid-state with spinning disk. In the original post, I poked fun at Texas Memory Systems having the slogan "World's Fastest Storage". Woody Hutsell, then VP of marketing for Texas Memory Systems, explained that the reason that TMS did not have faster benchmark results was because it did not have a million dollars to buy the fastest IBM UNIX server.
In my post [Good News and Bad News], I mentioned that Texas Memory Systems has an impressive SPC benchmark result. The Storage Performance Council [SPC] publishes the benchmarking industry standard by which all block-based storage devices are measured. It looks like the TMS performance test department finally got the million-dollar IBM server they needed for this.
My colleagues in marketing were not amused, afraid that mentioning small companies like TMS would give them a huge boost in marketing awareness, above and beyond what TMS could do on their own modest marketing budget, similar to the [Colbert Bump]. I could call it the Pearson Bump. If you first heard of Texas Memory Systems from my blog, or bought TMS products based on my discussion, please post a comment below!
IBM made history as the first major storage vendor to [break the 1 million IOPS barrier with Solid State Disk]. The project was known as "Quicksilver", and was able to demonstrate that a product like SAN Volume Controller with Solid-State Drives (SSD) can indeed provide a significant boost in performance to external disk arrays. The IBM 2145-CF8 and 2145-CG8 models allow up to four SSD in each node. I was asked not to blog the entire month of August, so that our upcoming September announcements would get more notice, but I couldn't resist covering Quicksilver. The original post had mentioned Texas Memory Systems, but were later removed to avoid the "Pearson Bump".
In my post [Day 2 IBM Storage University - Solutions Expo - TMS After-party], I mentioned that I attended the TMS after-party. Texas Memory Systems had just been qualified as Solid-State Drive (SSD) storage behind the IBM SAN Volume Controller, and the two products work extremely well together for IBM Easy Tier, the sub-volume automated tiering capability to optimize storage performance. I was able to catch up with my friend Erik Eyberg, and meet CEO and Founder Holly Frost.
Nearly half (43 percent) of IT decision makers say they have plans to use SSD technology in the future or are already using it in their datacenter. Solid-state can refer to both volatile Random Access Memory (RAM) and non-volatile Flash, and Texas Memory Systems has built solutions around both types. The survey question referred to non-volatile Flash Solid-State Drives (SSD) that do not require a battery to keep the data from fading away after the power goes out. Nearly all storage in the datacenter has volatile Random Access Memory (RAM).
Speeding delivery of data was the motivation behind 75 percent of respondents who plan to use or already use SSD technology. I would have thought this would have been 100 percent, but the other options included reduced energy consumption, and improved drive reliability, which are both also true with Solid-State Drives.
However, for those who were not using SSD today, the major factor was cost, according to 71 percent of respondents. On a Dollar-per-GB basis, Solid-State Drives continue to be anywhere from 10 to 25 times more expensive spinning disk. Last year's tsunami in Japan, and the floods in Thailand, have caused spinning disk prices to rise to cover component shortages, thereby shrinking the price gap between SSD and spinning disk.
Nearly half (48 percent) say they plan on increasing storage investments in the area of virtualization, cloud (26 percent) and flash memory/solid state (24 percent) and analytics (22 percent).
I am back from lovely Taipei. The IBM Top Gun class went well. Here are a few pictures of things I found interesting while I was there.
On the first day of class, I asked for some coffee. Our lovely class assistant, Ashley, brought me a cup with an interesting paper filter hanging on the edge. I have since learned that there are two drinks never to order in Taiwan: coffee and wine. If you enjoy either, you won't here. Instead, I drank the local "Taiwan Beer" and various types of tea.
Our class was on the 14th floor of the building, and there was this warning sign posted in the elevator. I have no idea what Chinese characters say, but we found the cartoon depictions of elevator dangers amusing. We interpreted the lower left corner to mean "Don't let your evil twin sister push you out of a moving elevator!"
I have to say that the variety of food was excellent. One night, we had dinner at a [Spanish Tapas] restaurant. The Spanish had a settlement on Taiwan island, known as Formosa back then, until driven out by the Dutch in 1642. We also had a traditional Chinese lunch, with dumplings, pickled cabbage, and "Lion's Head" soup.
From the classroom floor, we could see the Taipei 101 building, considered the third [tallest skyscraper in the world]. This wasn't here the last time I was in Taiwan.
On the last day, we were treated to some [Bubble tea], a specialty drink that originated in Taiwan in the 1980's. The straw was unusually thick, about twice as thick as a normal straw. We quickly figured out why. It was so that we could slurp up the brown floating things at the bottom. We didn't realize this until after the first sip. These floaties were actually Boba Tapioca pearls. The tea itself was delicious and sweet.
Special thanks to Joe Ebidia for managing the class, his assistant Ashley, and our local support team Justin and Stewart. I would also like to thank the staff at the Sherwood Hotel.
This week, I am in Taipei, teaching Top Gun class. There was concern that another typhoon would hit the island of Taiwan later this week, but it looks like it is now headed for Hong Kong instead.
Elsewhere in the world, there are several events going on next week, so I thought I would bring them to your attention.
ECTY - South Africa
Next week, Jerry Kluck, IBM Global Sales Executive for Storage Optimization and Integration Services, will be the keynote speaker at "Edge Comes to You" (ECTY) conference in South Africa. This is a one-day event, similar to the [ECTY event in Moscow, Russia] that I spoke at last June.
Here is the schedule for South Africa next week:
Monday, August 20, 2012 - Johannesburg
Wednesday, August 22, 2012 - Cape Town
(I have been to both Jo'burg and Cape Town back in 1994. A month after Apartheid had just ended, I was part of a small group of IBMers sent to re-establish IBM's business operations there. I would have liked to have attended the events next week, not just to hear Jerry speak, but also to see how much the country has changed over the past 18 years, but I could not get a work permit in time.)
If you are interested in attending either of these next week, contact your local IBM Business Partner or sales rep to attend.
Forrester's Total Economic Impact Study of Virtualized Storage
Virtualized storage can help organizations stretch their storage investment dollar and storage administration and management resources. Jon Erickson from Forrester Research will review the latest findings from IBM SAN Volume Control (SVC) users studied as part of the recently completed Forrester Total Economic Impact Study of IBM System Storage SAN Volume Controller.
Date: Tuesday, August 21, 2012
Time: 10:00 AM PDT / 1:00 PM EDT
Duration: 60 minutes
Among the findings, users were able to:
Avoid the capital cost of additional storage
Increase IT productivity
Provide greater end user data availability
The second presenter is Chris Saul, IBM Storage Virtualization Manager, who will explain how SVC can manage heterogeneous disk from a single point of control, autonomously manage tiered disk storage and can store up to five times as much data on your existing disk using IBM Real-time Compression.
Not all virtualization solutions are created equal! That's true for storage virtualization, like the SAN Volume Controller mentioned above, and it's true for server virtualization as well.
This webcast discusses the real-world impact on businesses that deploy IBM's PowerVM®
virtualization technology as compared to those using Oracle® VM for SPARC (OVM SPARC), Microsoft® Hyper-V, VMware® vSphere or other competing products.
Date: Wednesday, August 22, 2012
Time: 10:00 AM PDT / 1:00 PM EDT
Duration: 60 minutes
This webcast will include findings from a [Solitaire Interglobal] study of over 61,000 customer sites on the value of virtualization from a business perspective and how IBM's PowerVM provides real business value.
Other key discussion points that will be covered during this webcast include:
Behavioral characteristics of server virtualization technologies that were examined and analyzed from survey participant's environments
How IT colleagues were able to obtain a faster time-to-market for business initiatives when using IBM PowerVM
Why the learning curve time for PowerVM is as much as 2.58 times faster than for other offerings
Why VM reboot comparisons for PowerVM vs competitive platforms resulted in downtime of 5.5 times less than with other options
A TCO reduction of up to 71.4% for PowerVM compared to alternative options
This webcast will also feature an in-depth discussion on the IBM PowerVM solution from an IBM product expert who will share the unique virtualization features available when PowerVM is utilized within the IBM Power Systems™ environment.
Every year, I teach hundreds of sellers how to sell IBM storage products. I have been doing this since the late 1990s, and it is one task that has carried forward from one job to another as I transitioned through various roles from development, to marketing, to consulting.
This week, I am in the city of Taipei [Taipei] to teach Top Gun sales class, part of IBM's [Sales Training] curriculum. This is only my second time here on the island of Taiwan.
As you can see from this photo, Taipei is a large city with just row after row of buildings. The metropolitan area has about seven million people, and I saw lots of construction for more on my ride in from the airport.
The student body consists of IBM Business Partners and field sales reps eager to learn how to become better sellers. Typically, some of the students might have just been hired on, just finished IBM Sales School, a few might have transferred from selling other product lines, while others are established storage sellers looking for a refresher on the latest solutions and technologies.
I am part of the teach team comprised of seven instructors from different countries. Here is what the week entails for me:
Monday - I will present "Selling Scale-Out NAS Solutions" that covers the IBM SONAS appliance and gateway configurations, and be part of a panel discussion on Disk with several other experts.
Tuesday - I have two topics, "Selling Disk Virtualization Solutions" and "Selling Unified Storage Solutions", which cover the IBM SAN Volume Controller (SVC), Storwize V7000 and Storwize V7000 Unified products.
Wednesday - I will explain how to position and sell IBM products against the competition.
Thursday - I will present "Selling Infrastructure Management Solutions" and "Selling Unified Recovery Management Solutions", which focus on the IBM Tivoli Storage portfolio, including Tivoli Storage Productivity Center, Tivoli Storage Manager (TSM), and Tivoli Storage FlashCopy Manager (FCM). The day ends with the dreaded "Final Exam".
Friday - The students will present their "Team Value Workshop" presentations, and the class concludes with a formal graduation ceremony for the subset of students who pass. A few outstanding students will be honored with "Top Gun" status.
These are the solution areas I present most often as a consultant at the IBM Executive Briefing Center in Tucson, so I can provide real-life stories of different client situations to help illustrate my examples.
The weather here in Taipei calls for rain every day! I was able to take this photo on Sunday morning while it was still nice and clear, but later in the afternoon, we had quite the downpour. I am glad I brought my raincoat!
With all the announcements we had in June, it is easy for some of the more subtle enhancements to get overlooked. While I was at Orlando for the IBM Edge conference, I was able to blog about some of the key featured announcements. Then, later, when I got back from Orlando to Tucson, I was able to then blog about [More IBM Storage Announcements]. For IBM's Scale-Out Network Attach Storage (SONAS), I had simply:
"SONAS v1.3.2 adds support for management by the newly announced IBM Tivoli Storage Productivity Center v5.1 release. Also, IBM now officially supports Gateway configurations that have the storage nodes connected to XIV or Storwize V7000 disk systems. These gateway configurations offer new flexible choices and options for our ever-expanding set of clients."
In my defense, IBM numbers its software releasees with version.release.modification, so 1.3.2 is Version 1, Release 3, Modification 2. Generally, modification announcements don't get much attention. The big announcement for v1.3.0 of SONAS happened last October, see my blog post [October 2011 Announcements - Part I] or
the nice summary post [IBM Scale-out Network Attached Storage 1.3.0] from fellow blogger Roger Luethy.
Here is a diagram showing the three configurations of SONAS.
I have covered the SONAS Appliance model in depth in previous blogs, with options for fast and slow disk speeds, choice of RAID protection levels, a collection of enterprise-class software features provided at no additional charge, and interfaces to support a variety of third party backup and anti-virus checking software.
The basics haven't changed. The SONAS appliance consists of 2 to 32 interface nodes, 2 to 60 storage nodes, and up to 7,200 disk drives. The maximum configuration takes up 17 frames and holds 21.6PB of raw disk capacity, which is about 17PB usable space when RAID6 is configured. An interface nodes has one or two hex-core processors with up to 144GB of RAM to offer up to 3.5GB/sec performance each. This makes IBM SONAS the fastest performing and most scalable disk system in IBM's System Storage product line.
I thought I would go a bit deeper on the gateway models. These models support up to ten storage nodes, organized in pairs. The key difference is that instead of internal disk controllers, the storage nodes connect to external disk systems. There is enough space in the base SONAS rack to hold up to six interface nodes, or you can add a second rack if you need more interface nodes for increased performance.
SONAS with XIV gateway
XIV offers a clever approach to storage that allows for incredibly fast access to data on relatively slow 7200 RPM drives. By scattering data across all drives and taking advantage of parallel processing, rebuild times for a failed 3TB drive are less than 75 minutes. Compare that to typical rebuild times for 3TB drives that could take as much as 9-10 hours under active I/O loads!
In the configuration, each pair of storage nodes can connect to external SAN Fabric switches that then connect to one or two XIV storage systems. How simple is that? These can be the original XIV systems that support 1TB and 2TB drives, or the new XIV Gen3 systems that support 400GB Solid-state drives (SSD) and 3TB spinning disk drives. In both cases, you can acquire additional storage capacity as little as 12 drives at a time (one XIV module holds 12 drives).
The maximum configuration of ten XIV boxes could hold 1,800 drives. At 3TB drive per drive, that would be 2.4PB usable capacity.
The SONAS with XIV gateway does not require the XIV devices to be dedicated for SONAS purposes. Rather, you can assign some XIV storage space for the SONAS, and the rest is available for other servers. In this manner, SONAS just looks like another set of Linux-based servers to the XIV storage system. This in effect gives you "Unified Storage", with a full complement of NAS protocols from the SONAS side (NFS, CIFS, FTP, HTTPS, SCP) as well as block-based protocols directly from the XIV (FCP, iSCSI).
SONAS with Storwize V7000 gateway
The other gateway offering is the SONAS with Storwize V7000. Like the SONAS with XIV gateway model, you connect a pair of SONAS storage nodes to 1 or 2 Storwize V7000 disk systems. However, you do not need a SAN Fabric switch in between. You can instead connect the SONAS storage nodes directly to the Storwize V7000 control enclosures.
To acquire additional storage capacity, you can purchase a single drive at a time. That's right. Not 12 drives, or 60 drives, at a time, but one at a time. The Storwize V7000 supports a wide range of SSD, SAS and NL-SAS drives at different sizes, speeds and capacities. The drives can be configured into various RAID protection levels: RAID 0, 1, 3, 5, 6 and 10.
Each Storwize V7000 control enclosure can have up to nine expansion drawers. If you choose the 2.5-inch 24-bay models, you can have up to 480 drives per storage node pair, for a total of 2,400 drives. If you choose the 3.5-inch 12-bay models, you can have up to 240 drives per node pair, 1,200 drives total. At 3TB per drive, this could be 3.6PB of raw capacity. The usable PB would depend on which RAID level you selected. Of course, you don't have to limit yourself all to one size or the other. Feel free to mix 2.5-inch and 3.5-inch drawers to provide different storage pool capabilities.
All three SONAS configurations support Active Cloud Engine. This is a collection of features that differentiate SONAS from the other scale-out NAS wannabees in the marketplace:
Policy-driven Data Placement -- Different files can be directed to different storage pools. You no longer have to associate certain file systems to certain storage technologies.
High-speed Scan Engine -- SONAS can scan 10 million files per minute, per node. These scans can be used to drive data migration, backups, expirations, or replications, for example. It is over 100 times faster than traditional walk-the-directory-tree approaches employed by other NAS solutions.
Policy-driven Migration -- You can migrate files from one storage pool to another, based on age, days since last reference, size, and other criteria. The files can be moved from disk to disk, or move out of SONAS and stored on external media, such as tape or a virtual tape library. A lot of data stored on NAS systems is dormant, with little or no likelihood of being looked at again. Why waste money keeping that kind of data on expensive disk? With SONAS, you can move those files to tape can save lots of money. The files are stubbed in the SONAS file system, so that an access request to a file will automatically trigger a recall to fetch the data from tape back to the SONAS system.
Policy-driven Expiration -- SONAS can help you keep your system clean, by helping you decide what files should be deleted. This is especially useful for things like logs and traces that tend to just hang around until some deletes them manually.
WAN Caching -- This allows one SONAS to act as a "Cloud Storage Gateway" for another SONAS at a remote location connected by Wide Area Network (WAN). Let's say your main data center has a large SONAS repository of files, and a small branch office has a smaller SONAS. This allows all locations to have a "Global" view of the all the interconnected SONAS systems, with a high-speed user experience for local LAN-based access to the most recent and frequently used files.
If you want to learn more, see the [IBM SONAS landing page]. Next week, I will be across the Pacific Ocean in [Taipei], to teach IBM Top Gun class to sales reps and IBM Business Partners. "Selling SONAS" will be one of the topics I will be covering!
Next week we have two events related to Infrastructure for midsize businesses!
On Monday, August 6th, 1pm EDT, we have a TweetChat to cover "IT Infrastructure Improvements for Midsize Businesses." You can join at [http://tweetchat.com/room/expertsyschat] or simply tweet with hashtag: #ExpertSysChat
On Tuesday, August 7th, 12pm EDT, IBM's Midsize Insider is hosting me as a speaker for a Webcast: [Storage Management with IBM]. Midsize Insider is a valuable repository of expert content tailored for small-to-midsized business owners and IT decision makers.
Mark your calendars! Next month, IBM's Midsize Insider is hosting me as a speaker for a Webcast: [Storage Management with IBM], on August 7th, 12pm EDT. Midsize Insider is a valuable repository of expert content tailored for small-to-midsized business owners and IT decision makers.
The problems that used to keep storage managers awake at night -- power, cooling and physical footprint -- are being successfully addressed by technology, but a more vexing issue still remains: How to get more out of the limited supply of skilled storage management professionals.
Demand for storage capacity continues to grow far faster than the pool of people to manage it. With no end in sight to data growth, businesses need to apply technology and practices that distribute management responsibility to the people who need storage, and multiply the volumes of storage that skilled professionals can handle.
In this presentation, in this session, I will cover best practices and new tools that are enabling leaps in productivity, in three main areas:
Abandon the Craftsman Approach. Storage administrators need to discard some long-help myths about storage management and adopt new ways of thinking that enable them to handle significantly greater capacity.
Adopt software tools. Computers can now provide unprecedented guidance on storage optimization so that people don’t have to. Policy-based management, smart provisioning and automated tiering are among the innovations that are powering leaps in productivity.
Consider self-service portals. Companies are now exploring the self-service capabilities of private and public clouds. However, organizations need to adopt policies and limits in place to create an atmosphere of trust that enables efficient self-provisioning for storage.
Robert LeBlanc, IBM Senior Vice President for Middleware, gave a keynote presentation at the Red Hat Summit. Here is the [26-minute YouTube video]:
I am running Red Hat Enterprise Linux (RHEL) 6.2 as my primary laptop operating system. Most of IBM's products, like Lotus Notes for email, run natively on Linux for the desktop. I have a Windows XP running as a Linux KVM guest to run a few third-party software that we are still using.
Happy Fourth of July everyone! For my readers outside the U.S.A, this Wednesday marks America's [Independence Day]. Celebrations include parades during the day, and fireworks at night.
A long time ago, the IBM Tucson lab decided to close down the entire week, forcing everyone to take a week of their allotted vacation, so as to perform maintenance on the air conditioners and other equipment. Since then, many IBMers in Tucson have adopted this week as a good time to get out of town.
Most years, I head over to San Diego, California. This year, however, I will be taking a cruise on the Caribbean.
Can Structured Query Language [SQL] be considered a storage protocol?
Several months ago, I was asked to review a book on SQL, titled appropriately enough "The Complete Idiot's Guide to SQL", by Steven Holzner, Ph.D. As a published author myself, I get a lot of these requests, and I agreed in this case, given that SQL was invented by IBM, and is a good fundamental skill to have for Business Analytics and Database Management.
(FTC Disclosure: I work for IBM but was not part of the SQL development team. I was provided a copy of this book for free to review it. I was not paid to mention this book, nor told what to write. I do not know the author personally nor anyone that works for his publicist. All of my opinions of the book in this blog post are my own.)
Despite an agreed-upon standard for SQL, each relational database management system (RDBMS) has decided to customize it for their own purposes. First, SQL can be quite wordy, so some RDBMS have made certain keywords optional. Second, RDBMS offer extra features by adding keywords or programming language extentions, options or parameters above and beyond what the SQL standard calls for. Third, the SQL standard has changed over the years, and some RDBMS have opted to keep some backward compatibility with their prior releases. Fourth, some RDBMS want to discourage people from easily porting code from one RDBMS to another, known in the industry as vendor lock-in.
Throughout my career, I have managed various databases, including Informix, DB2, MySQL, and Microsoft SQL Server, so I am quite familiar with the differences in SQL and the problems and implications that arise.
Most authors who want to write about SQL typically make a choice between (a) stick to the SQL standard, and expect the reader to customize the examples to their particular DBMS; or (b) stick to a single RDBMS implemenation, and offer examples that may not work on other RDBMS.
I found the book "The Complete Idiot's Guide to SQL" covered the basics quite well, but with an odd twist. The basics include creating databases and tables, defining columns, inserting and deleting rows, updating fields, and performing queries or joins. The odd twist is that Steven does not make the typical choice above, but rather shows how the various DBMS are different than standard SQL syntax, with actual working examples for different RDBMS.
You might be thinking to yourself that only an idiot would work in a place that had to require knowledge of multiple RDBMS. The sad truth is that most of the medium and large companies I speak to have two or more in production. This is either through acquisitions, or in some cases, individual business units or departments implementing their own via the [Shadow IT].
(For those who want to learn SQL and try out the examples in this book, IBM offers a free version of DB2 called [DB2-C Express] that runs on Windows, Linux, Mac OS, and Solaris.)
Last week, while I was in Russia for the [Edge Comes to You] event, I was interviewed by a journalist from [Storage News] on various topics. One question stuck me as strange. He asked why I did not mention IBM's acquisition of Netezza in my keynote session about storage. I had to explain that Netezza was not in the IBM System Storage product line, it is in a different group, under Business Analytics, where it belongs.
While it is true that Netezza can store data, because it has storage components inside, the same could also be said about nearly every other piece of IT equipment, from servers with internal disk, to digital cameras, smart phones and portable music players. They can all be considered storage devices, but doing so would undermine what differentiates them from one another.
Which brings me back to my original question: Should we consider SQL to be a storage protocol? For the longest time, IT folks only considered block-based interfaces as storage protocols, then we added file-based interfaces like CIFS and NFS, and we also have object-based interfaces, such as IBM's Object Access Method (OAM) and the System Storage Archive Manager (SSAM) API. Could SQL interfaces be the next storage protocol?
Let me know what you think on this. Leave a comment below.
This week I am in Moscow, Russia for today's "Edge Comes to You" event. Although we had over 20 countries represented at the Edge2012 conference in Orlando, Florida earlier this month, IBM realizes that not everyone can travel to the United States. So, IBM has created the "Edge Comes to You" events where a condensed subset of the agenda is presented. Over the next four months, these events are planned in about two dozen other countries.
This is my first time in Russia, and the weather was very nice. With over 11 million people, Moscow is the 6th largest city in the world, and boasts having the largest community of billionaires. With this trip, I have now been to all five of the so-called BRICK countries (Brazil, Russia, India, China and Korea) in the past five years!
The venue was the [Info Space Transtvo Conference Center] not far from the Kremlin. While Barack Obama was making friends with Vladimir Putin this week at the G2012 Summit in Mexico, I was making friends with the lovely ladies at the check-in counter.
If it looks like some of the letters are backwards, that is not an illusion. The Russian language uses the [Cyrillic alphabet]. The backwards N ("И"), backwards R ("Я"), the number 3 ("З), and what looks like the big blue staple logo from Netapp ("П"), are actually all characters in this alphabet.
Having spent eight years in a fraternity during college, I found these not much different from the Greek alphabet. Once you learn how to pronounce each of the 33 characters, you can get by quite nicely in Moscow. I successfully navigated my way through Moscow's famous subway system, and ordered food on restaurant menus.
The conference coordinators were Tatiana Eltekova (left) and Natalia Grebenshchikova (right). Business is booming in Russia, and IBM just opened ten new branch offices throughout the country this month. So these two ladies in the marketing department have been quite busy lately.
I especially liked all the attention to detail. For example, the signage was crisp and clean, and the graphics all matched the Powerpoint charts of each presentation.
Moscow is close to the North pole, similar in latitude as Juneau, Alaska; Edinburgh, Scottland; Copenhagen, Denmark; and Stockholm, Sweden.
As a result, it is daylight for nearly 18 hours a day. The first part of the day, from 8:00am to 4:30pm, was "Technical Edge", a condensed version of the 4.5 day event in Orlando, Florida. I gave three of the five keynote presentations:
Game Change on a Smarter Planet: A New Era in IT, discussing Smarter Computing and Expert-Integrated systems, based on what Rod Adkins presented in Orlando.
A New Approach to Storage, explaining IBM Smarter Storage for Smarter Computing, IBM's new approach to the way storage is designed and deployed for our clients
IBM Watson: How it Works and What it Means for Society Beyond Winning Jeopardy! explaining how IBM Watson technologies are being used in Healthcare and Financial Services, based on what I presented in Orlando.
(Note: I do not speak Russian fluently enough to give a technical presentation, so I did then entire presentation in English, and had real-time translators convert to Russian for me. The audience wore headphones. However, I was able to sprinkly a few Russian phrases, such as "доброе утро", "Я не понимаю по-русский" and "спасибо".)
After the keynote sessions, I was interviewed by a journalist for [Storage News] magazine. The questions covered a variety of topics, from the implications of [Big Data analytics] to the future of storage devices that employ [Phase Change Memory]. I look forward to reading the article when it gets published!
The afternoon had break-out sessions in three separate rooms. Each room hosted seven topics, giving the attendees plenty to choose from for each time slot. I presented one of these break-out sessions, Big Data Cloud Storage Technology Comparison. The title was already printed in all the agendas, so we went with it, but I would have rather called it "Big Data Storage Options". In this session, I explained Hadoop, InfoSphere BigInsights, internal and external storage options.
I spent some time comparing Hadoop File System (HDFS) with IBM's own General Parallel File System (GPFS) which now offers Hadoop interfaces in a Shared-Nothing Cluster (SNC) configuration. IBM GPFS is about twice as fast as HDFS for typical workloads.
At the end of the Technical Edge event, there was a prize draw. Business cards were drawn at random, and three lucky attendees won a complete four-volume set of my book series "Inside System Storage"! Sadly, these got held up in customs, so we provided a "certificate" to redeem them for the books when they arrive to the IBM office.
The second part of the day, from 5:00pm to 8pm, was "Executive Edge", a condensed version of the 2 day event in Orlando, designed for CIOs and IT leaders. Having this event in the evening allowed busy executives to come over after they spend the day in the office. I presented IBM Storage Strategy in the Smarter Computing Era, similar to my presentation in Orlando.
Both events were well-attended. Despite fighting jet lag across 11 time zones, I managed to hang in there for the entire day. I got great feedback and comments from the attendees. I look forward to hearing how the other "Edge Comes to You" events fare in the other countries. I would like to thank Tatiana and Natalia for their excellent work organizing and running this event!
Well, it's Tuesday again, and you know what that means... IBM announcements!
Last week, IBM had a big storage launch of various products, with the June 4 announcements at the IBM Edge 2012 conference. I provided highlights in my post [IBM Edge Announcements]. As promised, here are the rest of the announcements.
SONAS v1.3.2 adds support for management by the newly announced IBM Tivoli Storage Productivity Center v5.1 release. Also, IBM now officially supports "Gateway configurations" that have the storage nodes connected to XIV or Storwize v7000 disk systems. These gateway configurations offer new flexible choices and options for our ever-expanding set of clients.
ProtecTIER appliances and gateways
IBM ProtecTIER line of data deduplication appliances and gateways add CIFS file system support. Rather than using OST or a VTL interface, you now have CIFS as a new option for host attach. Also, IBM introduces the new TS7620 Express model, with options for 5.4TB and 11TB in capacity, replacing the previous TS7610 entry level.
LTFS Storage Manager
The Linear Tape File System (LTFS) allows files to be stored on tape cartridges in a manner that allows them to be mounted as file systems, much like a USB memory stick. The new LTFS Storage Manager software allows you to manage a collection of files across a set of cartridges, moving files from one cartridge to another, consolidating valid data onto fewer cartridges, and removing files no longer needed. This is sometimes referred to as "lifecycle management".
Tape System Library Manager
When IBM first introduced the "shuttle" that allowed up to fifteen TS3500 tape libraries to be connected together into a single system, only HPSS customers could take advantage of this. Software was required to coordinate the movement of cartridges from one library to another. The new IBM Tape System Library Manager now offers an alternative to HPSS for coordinating this activity.
DS8000 v6.3 microcode
IBM now offers 400GB solid-state drives. IBM's market leading support for Full Disk Encryption (FDE) is now extended to cover all drive speeds, from the slowest 7200RPM NL-SAS drives up to the fastest solid-state. IBM Easy Tier extends its super-easy implementation to work across all three of these tiers including encryption.
IBM now offers implementation services for IBM XIV Gen3 storage system, and the N series models 3220 and 3240.
This week I am on the road visiting various clients. Next week, Moscow Russia for the "Edge Comes to You" event!
This week I am in Orlando, Florida for the IBM Edge conference. This is the last day, so it ends early for people who want to get home to their datacenters (er.. families) for the weekend.
How Real-Time Compression Can Maximize Storage Efficiency for Production Applications
This was a split session with two speakers. First, Ian Rimmer, Senior IT Engineer and Architect at iBurst, presented their experience with the IBM Real-Time Compression Appliance in front of NetApp NAS storage arrays. Second, Jerry Haigh, IBM offering manager for IBM System Storage, presented the new Real-Time compression feature announced this week on IBM SAN Volume Controller (SVC) and Storwize V7000.
iBurst is the #1 Wireless Telecom for South Africa. The also offer cable broadband and VOIP. They have 200 employees servicing 120,000 subscriber/households. They need to keep five years' worth of text files, and have chosen real-time compression of their NAS storage. This was before IBM acquired the Storwize company, as they have been using it for the past six years.
The monetary savings from compression was used to purchase Performance Accelerator Modules (PAM) cards for their NetApp NAS gear, which benefit from the compression (more data stored in SSD to improve performance).
For backup, they use NDMP with Symantec NetBackup that keeps data in its compressed form as it is written to tape. They have an IBM TS3100 library with LTO tape as the backup repository.
Jerry Haigh presented Real-Time compression for primary disk data. Unlike the competition, this is designed to be used with primary data, including databases, and does this real-time, not post-process. In some performance tests, DB2 compressed on 48 drives out-performed the same data uncompressed on 96 drives. In another test focused on VMware Vmark benchmark, the compressed data was able to be same or better performance as uncompressed. In a third test with SVC virtualizing XIV running Oracle ORION test, the Oracle databases compressed 50 to 64 percent, and had better performance.
For those who already have SVC or Storwize V7000, consider a 45-day trial to check out compression for yourself.
NAS File Systems: Access and Authentication
Mark Taylor, IBM Technical Specialist for SONAS, N series and Storwize V7000 Unified, presented the nuances of authentication and authorization for NAS file systems. The differences between these two are:
Authentication - Yes, you are who you are.
Authorization - Yes, you are permitted to do what you are trying to do
(Prior to working with SONAS, my only experience with access and authentication in NAS was setting up my LAN at home, which I have connecting my Mac, Linux and Windows machines. I have both N series and SONAS at the IBM Executive Briefing Center in Tucson, Arizona, so I know first-hand how complicated NAS access and authentication systems can be.
A few months ago, I taught "Intro to NAS" as one of my topics at the Top Gun class in Argentina and Brazil. Several of the students had mentioned they thought they knew NAS solutions but had not realized all the technical issues with access and authentication that I discussed in my presentation.)
Mark explained the differences between Windows NTFS-style System identifiers (SID), versus UNIX-style user and group identifiers (UID, GID). For NAS solutions that support both CIFS and NFS, there are four options:
Microsoft Active Director (AD) extended with Identity Management for UNIX, formerly known as Services for UNIX (SFU). AD servers normally store SID information, but the extensions add extra columns to hold UID/GID mappings.
AD with Network Information Service (NIS) server. The problem with this approach is that AD and NIS are separate databases, and you need to coordinate updates to them, and their backups.
Lightweight Directory Access Protocol (LDAP) with SAMBA extensions. LDAP holds UID/GID information, and the SAMBA extensions adds extra columns to hold SID mapping.
Local mapping. The dangerous part of local mapping is that the storage admin is also the security admin, and you may want different people doing these roles.
Of these four methods, Mark recommends the first and third as best practices for multi-protocol authentication.
SID-to-UID mapping, UID-to-SID mapping
SONAS and Storwize V7000
SID-to-UID/GID mapping, NFS v4 ACLs
NFS v4 ACLs
Mark then explained how NFS v4 ACLs work, basically an ordered collection of "Access Control Elements" or ACEs. Each ACE on the ACL may "allow" or "deny" the request. You want to avoid "Inheritance" as that can cause problems and unxpected results.
That's it folks. Next week, I am spending time with my research buddies at the Almaden Research Center near San Jose, California, and then it is off to Moscow, Russia to kick off a series of IBM events called "Edge Comes to You" (ECTY).
The ECTY conferences will be a smaller subset of the Edge conference here in Orlando, but offered in other countries for those who were unable to travel to the United States.
This week I am in Orlando, Florida for the IBM Edge conference. Thursday evening after all the other sessions, we had a Free-for-All, a Q&A panel across all storage topics, moderated by Scott Drummond. The conference officially ends at noon tomorrow, but for many, this is the last session, as people fly out Friday morning. Here are the questions and the panel responses during the session.
When will IBM unify their storage management between Mainframe z/OS and the distributed systems platforms?
IBM offers a Change and Configuration Management Data Base (CCMDB) for this purpose with appropriate collectors from z/OS and distributed systems, but hasn't sold well.
When will IBM devices have RESTful interfaces?
Both IBM Systems Director and IBM Tivoli Storage Productivity Center (TPC) offer RESTful APIs. IBM Systems Director can manage z/VM and Linux on System z, as well as Power Systems and x86 based distributed systems. Since October 2008, IBM's Project Zero introduced RESTful interfaces to PHP and Groovy software running on WebSphere sMash environments. We have not heard much about this since 2008.
Will IBM TPC support NPIV on Power Systems?
TPC 5.1 has toleration support for this, showing the first port connection discovered, but not all connections, and we expect to retrofit this toleration to TPC 4.2.2 Fixpack 2. Hopefully, we will have full support in a future release.
We would like TPC for Replication to run on Linux for System z. We do not run z/OS at the disaster recovery site location.
Submit an IBM Request for Enhancement [RFE] for this. We have TPC for Replication on z/OS, as well as the distributed systems version that runs on Windows, Linux and AIX.
We have enhancements we would like to see for XIV and SONAS also, can we use the RFE process for this also?
Yes, submit the requirements for our review.
We heard the Statement of Direction that there would be storage integrated into the PureSystems. What exactly does that mean?
The PureSystems family of expert-integrated systems is based on a new chassis that has a front part, a midplane, and a back-part. All IBM System Storage products that support x86 and Power Systems can work with PureSystems. However, IBM does not yet offer storage that fits in the front part of the PureFlex chassis, but the Statement of Direction indicates that we intend to offer that option. Until then, the IBM Storwize V7000 is the storage of choice that can be put into the PureSystems rack, but outside the individual chasses.
We see some features like Real-Time Compression being put into the SAN Volume Controller (SVC), and other features put into the back-end devices. How are we supposed to make sense of this?
IBM's new pilot program, the SmartCloud Virtual Storage Center, to bring these all together. In general, we have design teams of system architects that determine which features go in which products, and prioritize accordingly.
We heard the IBM Executives during the opening session indicate that IBM's strategy involves supporting Big Data, but I haven't seen any storage that supports native Hadoop interfaces. Did I miss something?
First, I want to emphasize that Big Data is more than just MapReduce workloads. IBM offers Streams and BigInsights software to handle text, as well as Business Intelligence and Data Warehouse solutions for structured data. IBM's General Parallel File System (GPFS) has a Shared-Nothing-Cluster (SNC) mode with Hadoop interfaces that runs twice as fast as Hadoop's native HDFS file system. The storage products we recommend for Big Data are the SONAS and the DCS3700 disk systems, as both are optimized for the sequential workloads Big Data represents.
Everytime we upgrade our SVC, we review the list for SDDPCM multi-pathing and see that we need to upgrade our back-end DS8000 microcode up to recommended levels. Can we get a list of combinations that work from other customers?
The advantage of storage hypervisors like SVC is that we can separate the multi-pathing driver from the back-end managed disk systems. You only need the SDDPCM to support the SVC, not the back-end devices. For the most part, SVC has not dropped support for any level of previously supported OS or multi-pathing software.
On SVC, when we migrate volumes (vDisks) from one storage pool to another, we would like to throttle this process during FlashCopy.
Yes, we had several requests like this, which is why we now recommend using Volume Mirorring to perform migrations. In fact the GUI wizard uses Volume Mirroring by default when migrations are performed. As for throttling, IBM has implemented "I/O Priority Manager" that offers Quality of Service classes for DS8000 and XIV Gen3, and might consider porting this to other products in our portfolio.
Sizing systems is an art. I just need to know if the DS8000 is running hot. Can we have the equivalent of "red lines" for our disk systems similar to automobile engines?
Storage Optimizer was added to TPC 4.2 to help in this area, identifying heat-maps for IBM DS8000, DS6000, DS5000, DS4000, SVC and Storwize V7000. We recommend you look at the performance violation reports.
How can we evaluate the characteristics of our workloads?
Yes, TPC can do this.
When we are replacing non-IBM storage with IBM, we don't have good tools to evaluate the non-IBM equipment. What is IBM doing for this?
IBM's Disk Magic modeling tool can take inputs from a variety of sources, including iostat from the servers themselves. You can also install a 90-day trial of TPC to help with this.
We really like EMC's "Grab" program, does IBM have one also?
Updating the Host Attachment Kit (HAK) for AIX is quite painful for the SVC. We prefer the method employed for the XIV.
Thanks for the feedback.
For SVC, we need to correlate disk with VMware and VIOS. Can we get vSCSI information on VIOS?
TPC 5.1 has this support, and we believe it has been retrofitted to TPC 4.2.2 Fixpack 2, coming out this month.
Currently, with SVC, when volumes are part of a Global Mirror (GM) session, we need to cancel GM, expand the source volume, expand the target volume, then restart GM. We would like this to be fully automated and non-disruptive.
Sounds like a great requirement to submit for the RFE process.
Can we get an RSS Feed for the RFE community.
Yes, you can subscribe to it. You can also set up "Watch Lists".
Thanks to all of the IBM experts on the panel for their participation at this event!
This week I am in Orlando, Florida for the IBM Edge conference. Here is a recap of Day 4 afternoon sessions which related to Cloud computing.
IBM SmartCloud Enterprise -- Object Storage
George Contino, IBM GTS Consultant for Cloud Storage Service Enablement, presented IBM's latest Object Storage offering, based on an alliance IBM formed with Nirvanix last October 2011, launched January 31, 2012. It is part of the IBM SmartCloud Enterprise system.
IBM currently has two datacenters for this now, Secaucus NJ and Frankfurt Germany, but will have five by end of 2012, and hopefully seven datacenters by nid-year 2013.
The storage is then divided in several layers:
Customer master account, assigned a 128-bit encryption key
Name spaces by department or LOB
User file objects
The objects are given random names, with the real customer-assigned file names stored elsewhere, to provide additional privacy through obfuscation. For added security, it uses Two-Factor Authentication, requiring the users to provide both the 128-bit encryption key and the password.
There are three ways to access data:
Proprietary API - An API is available on Windows and Linux. Symantec NetBackup, BackupExec and Commvault Simpana have already coded to the Nirvanix API to allow backups to be stored in the Nirvanix storage cloud. IBM InfoSphere Optim can archive data to the Nirvanix storage cloud.
CloudNAS - Nirvanix provides software that provides CIFS and NFS interfaces, that converts to the Nivranix API. IBM Tivoli Storage Manager can send backups and archives to the Nirvanix storage cloud using this approach.
Cloud Storage Gateway - Third parties have developed hardware that runs the CloudNAS software, or directly codes to the API, to provide standard interfaces to the local clients, and provides access to the Nirvanix storage cloud. Two examples were Panzura File System Controller and Twinstrata Cloud Array Gateway.
One of Nirvanix's partners is OxygenCloud, which allows mobile/laptop access to work files. This includes security checks on Active Directory or LDAP, AES-256 bit encryption and HTTPS protocol support. For example, if you had to give a bunch of PDF files to your clients outside your company, you could create a folder, and send out a URL link to the clients, and this link would be valid for the next 14 days for them to download the files.
How University of Wisconsin-Milwaukee (UWM) moved SAP to the Cloud
Maik Gasterstaedt, IBM Technical Enablement for SAP, Storage and Cloud solutions, presented this session on the deployment of an SAP cloud at UWM. Worldwide, SAP has established five University Competency Centers (UCC) to provide SAP cloud services to other universities, and UWM is one of these five UCC.
Basically, the UWM manages SAP instances that are then "rented out" to 107 other universities. An SAP instance represents a "sample company" that could be used in a course curriculum, for example, "Global Bikes, Inc.", "Fitter Snacker", or IDES. An SAP Client represents a fresh copy of the data for this sample company.
UWM charges each University per "SAP client" per semester. Suppose a professor will teach three classes on SAP. He can arrange the SAP clients depending on how much he is willing to spend.
Get one SAP Client to be shared across all three classes. All three classes would be using the same sample company.
Get an SAP Client for each class. Each class could be based on the same or different sample companies.
Get one or more SAP Clients for each class. In this case, for example, a class could get two or more sample companies.
The problem was that they were running on Sun servers approaching end-of-life. They decided to switch to IBM, running 43 SAP Instances on AIX with two Power750 servers, 7 SAP instances on Windows guests of VMware across two BladeCenter chassis using HS22 blades, XIV storage, backed up by Tivoli Storage Manager and Tivoli Storage FlashCopy Manager. They can run 50 SAP clients on each SAP instance. Each client could be rented out to different professors at different universities.
They started installation April 1, and the entire system was running in production by August 15, less than five months end-to-end.
The results were stunning. SAP instance provisioning used to take 5 days, now takes 12 hours. Backups that used to take an hour complets in about 30 seconds.
The conference is almost over folks! Just a few sessions tomorrow and then it is all done.
With my colleague, Mike Griese, presenting TPC 5.1 and the IBM SmartCloud Virtual Storage Center earlier this week, you might wonder what is left to say. Mike's session was intended more for clients who already have TPC deployed, but my session is more of an introductory session.
I was the original architect of the product back in 2000-2003, so have some insight into the history, motivations and design principles applied to each version of the product. It has evolved nicely over the years, and while I am no longer working full-time on the product, I am still very much involved, and am consulted by the current architects and product managers for direction and opinion going forward.
I presented an overview of the overall product as it stands today in its current v4.2.2 version, and gave a few highlights of what to expect in the upcoming TPC 5.1 announced this week.
Encryption and Key Management in the Cloud: The Top 6 Concerns to Ensure a Secure and Reliable Solution
This was a split session with two speakers. The first speaker was Richard Moulds, VP of Strategy and Marketing from Thales, and the second speaker was Gordon Arnold, IBM Senior Technical Staff Member (STSM) and Software Architect for Tivoli Security Management.
Richard presented security issues in the cloud. He is an author of several books, including "Key Management for Dummies" and "Data Protection and PCI Compliance for Dummies". Thales is a large French companay of 70,000 people nobody in the USA has heard of, but is a major company in the area of IT Security. He presented survey results about people's perceptions and attitudes towards encryption and security issues in the cloud.
The security threats in the Cloud were presented as the "Seven Deadly Sins":
Data loss and leakage, including data that is not deleted with resources are re-used for other purposes
Shared technologies, especially in Cloud environments that do not have robust multi-tenancy
Malicious insiders, such as administrators being bribed to provide access to sensitive data
Account or service hijacking, including those that pretend to be someone else, asking for password resets
Insecure APIs for applications and services, many of these APIs were developed quickly, recently, and perhaps without the robust review from a security perspective
Abuse of the Cloud, such as using the Cloud itself to crack passwords or break decryption passwords through parallel processing
Unknown risk profile, as few Cloud providers have certified security capabilities
Gordon Arnold (IBM) presented IBM's Encryption and Key management. IBM has two products: IBM Tiovli Key Lifecycle Manager (TKLM) and IBM Security Key Lifecycle Manager (SKLM). These are KMIP v1.0 compliant today. The OASIS group is currently reviewing KMIP v1.1 enhancements that includes some suggestions from IBM.
IBM's use of Key Encrypting Keys on disk and tape has proven to be quite useful. The only copy of the encryption key is on the media, and is then encrypted by an authorization key. If you need to defensibly delete the data for compliance reasons, you can simply destroy the encrption key.
At lunch, I spoke with Scott Laningham who was doing video interviews. For years, Scott was the #1 blogger on IBM developerWorks until I took over the title last year. We discussed working on a video in the future on this.
Earlier this year, I wrote a Web article titled [Data Footprint Reduction] which covered data deduplication and compression, and was asked to present this at IBM Edge. I have expanded it to include:
Space-Efficient Point-in-Time copies
After I presented the basic concepts, Sanjay Bhikot, a Unix and Storage admin at RICOH, presented his real-world experiences with data deduplication using the IBM ProtecTIER and real-time compression Beta experience using the SAN Volume Controller (SVC).
IBM Active Cloud Engine Implementation on IBM SONAS 1.3 and IBM Storwize V7000 Unified
John Sing (IBM) presented the latest enhancements in the v1.3.2 release of SONAS and Storwize V7000 Unified.
Introducing VMware vSphere Storage Features
Fellow blogger Stephen Foskett presented this session on VMware's storage features. This included VMware APIs for Array Integration (VAAI), VMware Array Storage Awareness (VASA), vCenter plug-ins, and a new concept he called "vVol" which de-multiplexes the "I/O Blender" that server hypervisors do by tagging individual requests to individual OS guests to provide added benefit. IBM is a leading reseller of VMware, so it makes sense that most of our storage meets all of Steve's requirements for recommendation.
IBM's Storage Strategy in the Smarter Computing Era
Last year, I presented this on the fourth day of the conference, and feedback we received from attendees was that this should have been presented sooner in the week, as it provides great context for the more detailed product presentations.
To address this concern, the IBM executives presented IBM strategy on Monday's keynote session, but allowed me to present this on Wednesday for several reasons:
You may have missed the keynote session. For example, you may not have arrived in time to hear the executives speak due to weather or mechanical problems causing travel delays.
You may have attended the keynote session, but want to hear it again. Maybe you were a bit hung-over, or just may have been overwhelmed with the size and scope of this event. I have read for strategic topics, audiences may have to hear the message five to seven times before they truly appreciate and understand it.
You may want to ask questions, and explore the implications in more detail. While keynote sessions can reach a broader audience, the communication is very much uni-directional. With break-out sessions with a few hundred people, the venue is more intimate and can afford opportunties for information exchange.
The title of this session rolls off the tongue nicely, much like "James and the Giant Peach", "Harold and the Purple Crayon", or "Charlie and the Chocolate Factory".
When people say they are interested in "Cloud Storage", what exactly do they mean. After discussions with hundreds of clients, IBM has worked out a "taxonomy" that identifies four distinct types of storage:
In this session, I presented how IBM SONAS addresses all four of these categories, as well as other IBM storage products that can address specific categories in the taxonomy.
In the evening, the attendees at IBM Edge joined the attendees from Innovate2012 (focused on IBM Rational products) at SeaWorld, with BBQ dinner, rides, Shamu the whale show, and a concert featuring Foreigner!
This week I am in Orlando, Florida for the IBM Edge conference. Tuesday afternoon we had a Birds-of-a-Feather (BOF) session to discuss social media. I was the moderator. We had two independent bloggers on the panel: [Jon Toigo] and [Steve Foskett]. We had several IBM social media experts, including Jack Arnold, Scott Drummond, Mary Hall, Nick Harris, and Rich Swain. Also joining us was Alex Hollingworth, social media expert from Emulex.
At the opening session, Deon Newman suggest we re-tweet him, isn't that plagiarism? What is your take on this?
The important thing is to give credit where it is due. Avoid screen scraping others and passing it off as your own. When you re-tweet someone, you give them credit for their original tweet. You are basically saying, "I could not have said it better myself!" With blogs, you can do the same by linking to other blog posts.
I am active in social media, but am having trouble getting the older colleagues in the IT department to participate. I want them to write down all the knowledge in their heads.
The best way to get employees to do anything new or different is to show them how it benefits them. For example, if the elders are tired of answering the same questions over and over, have them start an internal wiki, blog or knowledgebase to capture the answers to frequent questions. This will save them time, so they can see value for themselves. I suggest looking at IBM Lotus Connections which provides collaboration tools inside your firewall, accessible only to internal employees of the company.
How do we differentiate facts from opinions in our social media writings?
You can always be explicit, for example IMHO stands for "In my humble opinion". I find that blogs are 99 percent opinion, and 1 percent fact, so it is easier to point out the facts linking or citing sources, and let the rest of your writing be considered opinion.
I would like to find people on Linkedin to establish business relationships with the storage administrators, decision makers and influencers within the companies I want to sell to, how do I best do that?
Nobody likes cold calls. If you upgrade to a "Pro" account on LinkedIn, you can send 15 to 25 "Inmail" emails through their system to introduce yourself. Otherwise, consider finding someone in your network that knows them, and arrange for them to provide the mutual introduction for you.
How do I find people to follow related to the topics I am interested in, like storage?
There are tools like [Tweetadder] to help you find people to follow. Or, just search on certain hashtags, and add people you find that use them.
I am concerned about privacy? What can I do to protect my privacy?
Decide up front which topics are off-limits in your blog or other social media. For services like Facebook, check your privacy settings every 30 days. Several people have opted to create a special "Facebook Page" that represents their professional brand, so that the rest of Facebook can be used for friends and family.
I want to start a new blog, which service should I use?
Services like Blogger, Blogspt and TypePad are generally easy to set up. Wordpress is more advanced, but can be more complicated to set up.
I don't care for writing a blog, how can I set up a video blog, or vlog?
Consider creating a channel on YouTube. Another popular site is Vimeo. A "Pro" account of Vimeo provides added features.
I am new to Twitter, what tools should I look into?
I suggest you look at HootSuite. This lets you post to Twitter, Facebook and Linkedin. You can schedule when a tweet will be posted, so you can right them in advance and schedule them for a certain date and time. Also, if you have a blog, you can have Hootsuite send out tweets automatically with the titles and link to each blog post.
How much effort should we put in to Social Media?
As much or as little as you want. Don't force yourself to spend more time than you want. Typically, people spend 1-2 hours per day. Cut down how much you spend watching television to make up the difference. Set up "Google Alerts" that can send you emails when certain phrases appear anywhere. There are also social bookmarking tools like Instapaper, Delicious or Diigo that can save bookmarks in the cloud for things that you want to read, but don't have time to read now.
Which social media would be the best to get chicks.
Writing a technical blog with good quality content. Girls want to be with you. Guys want to be you.
How can I use social media to provide feedback about specific products?
IBM now has a [Reviews and Ratings] for its IBM System Storage products. Consider writing a review today!
Thanks to all of the panel for their help with this!
Well it's Tuesday again, and you know what that means... IBM announcements! Yesterday, at the IBM Edge conference here in Orlando, Florida, IBM announced its new apporach to storage, and a whole bunch of storage products, enhancements, and services. I will focus on some key ones here, and save the rest for next week.
IBM SAN Volume Controller (SVC) v6.4
The SVC is IBM's enterprise-class storage hypervisor. The latest software release, v6.4, can be installed on any SVC hardware, from the 2145-8F2 introduced back in 2005, to newer models like the 2145-CG8. Here are the key features:
Fibre Channel over Ethernet (FCoE) -- This is complete end-to-end support. For SVC units with 10GbE ports, these ports can be now be used for FCoE. This allows hosts to attach to SVC via FCoE, allows SVC node-to-node communication for clustering, and allows SVC to communicate to back-end devices via FCoE.
Real-Time Compression -- IBM ported over the patent Random Access Compression Engine (RACE) from the Real-Time Compression Appliances to SVC v6.4. This allows primary data, accessed via block-based protocols, to be compressed up to 80 percent. This feature is an extra priced feature by TB.
Non-Disruptive Volume move between I/O Groups -- If you don't already have SVC, you don't need to worry about this. For existing SVC customers, this allows volumes to be associated with two or more I/O groups, and that you can add or remove I/O groups non-disruptively. For example, if you want to move a volume from IOG1 to IOG2, then you add IOG2 to the list of I/O groups for the volume, let the multi-pathing software discover the additional paths, the remove IOG1, which then marks the previous IOG1 paths inactive. All this can be done while applications read and write data.
Dedicate FCP ports for Replication -- If you activate the two 10GbE Ethernet ports for FCoE, you can free up two FCP ports that you can dedicate for long-distance Metro Mirror or Global Mirror.
If you have SVC today, but are running an old release like v4.3 or v5.1, I recommennd you upgrade up to at least v6.2.05 release now. This release has been out for a year and is very stable, and serves as a great platform for a later upgrade to SVC v6.4.
IBM Storwize V7000 v6.4
The Storwize V7000 is IBM's midrange storage hypervisor. The latest software release, v6.4, can be installed on existing block-only Storwize V7000 units in the field. The Storwize V7000 v6.4 gets all the features listed above, as well as the following:
Four-way clustering -- Previously, you could cluster two Storwize V7000 controller enclosures together (4 canisters total). To cluster three or four controllers required an RPQ. Now, IBM supports up to four Storwize V7000 controller enclosures (8 canisters) without an RPQ.
Direct Fibre Channel attach -- A lot of people are using Storwize V7000 inside single-rack configurations, so it makes sense not to require a SAN switch for just a few Windows, Linux or VMware servers. An RPQ is now available to allow this to happen.
IBM Tivoli Storage Productivity Center (TPC) v5.1
TPC is already ranked one of the best Storage Infrastructure Management software in the market, and this release will just solidify its lead. Key features include:
Upward integration to higher level management systems
A new, intuitive, easy-to-use web-based GUI inspired by the XIV GUI
Integration of COGNOS to be able to generate and customize reports
Support for SONAS systems
There are several presentations on TPC this week that will go into more detail. Check out the [TPC Facebook page].
My latest book Inside System Storage: Volume IV is now available!
Yes, can you believe it? I have published my fourth volume in my "Inside System Storage" series! It is available in three formats:
Hardcover with dust jacket
eBook (Adobe Acrobat PDF)
You can order this, and all my other books, in all formats, directly from my [Author Spotlight] page. The paperback will also be available soon from other online booksellers, search for ISBN 978-1-105-72213-4.
IBM DS3500 Express
The DS3500 is our entry-level block-based device, designed specifically for random I/O workloads. This includes databases, email repositories, traditional business applications, and on-line transactional workloads. Here are the new features:
Dynamic Disk Pooling, similar to what XIV does to reduce disk rebuild times, but using a RAID-6 like approach per chunk of data.
Thin Provisioning using Dynamic Disk Pooling
Asynchronous Logical Unit Access (ALUA) failover
Enhanced FlashCopy, improved scalability, consistency groups and rollback support
VMware API for Array Integration (VAAI) support. This includes Write Same, Extended Copy, and Atomic Test & Set.
The DS3500 replaces the previous models of DS3200, DS3300 and DS3400 models.
The DCS3700 is our entry-level/midrange block-based device, replacing the DCS9900 model, designed specifically for sequential I/O workloads. This includes Big Data analytics, Hadoop, High Performance Computing (HPC), video surveillance, and television broadcasting. It holds 60 drives in a 4U controller enclosure.
I presented IBM's Smart Archive strategy and the storage products IBM offers to archive data and meet compliance regulations:
The differences between backup and archive, including a few of my own personal horror stories helping companies who had foolishly thought that keeping backup copies for years would adequately serve as their archive strategy
The differences between Write-Once Read-Many (WORM) media, and Non-Erasable, Non-Rewriteable (NENR) storage options.
How disk-only archive solutions become "space heaters" for your data center.
An overview of the various storage hardware options from IBM.
An explanation of the different IBM software offerings to help complement the storage hardware choices.
IBM TotalStorage Productivity Center (TPC): New Features and Functions
Mike Griese, IBM program manager for TPC, presented the latest in TPC 5.1 version announced this week. His session was organized into four key sections:
Insights - TPC 5.1 integrates COGNOS reporting, which allows custonmization of reports and ad-hoc exploration and analysis. Since the reports are not binary-compiled into the product, IBM can ship new COGNOS reports as templates outside the normal TPC release schedule. Also, TPC 5.1 got smarter on reporting on server virtualization hypervisor environments to avoid double-counting.
Recommendations - TPC 5.1 can analyze your usage patterns across the entire data center and make recommendations to move data from one storage tier to another. You can then act on these recommendations by moving data from one tier to another, either "up-tier" to faster storage, or "down-tier" to less expensive storage, using a storage hypervisor like IBM SAN Volume Controller. This is complementary to features like Easy Tier which optimize within a single disk system.
Performance - TPC 5.1 uses a new web-based GUI, based on AJAX, HTML5 and Dojo widgets, inspired by the IBM XIV GUI, and similar to the web-based GUI of SAN Volume Controller, Storwize V7000 and SONAS.
Mike also explained the new TPC 5.1 packaging. Instead of having a variety of components like "TPC for Disk", "TPC for Data", and "TPC for Replication", the new packaging simplifies this down to two levels of functionality. The basic level supports block-level devices, including disk performance, replication and SAN fabric management. The advanced level adds support for files and databases, including support for Cloud management such as SONAS environments.
Dan Zehnpfennig, Solution Architect, talked about his experiences installing TPC 5.1 and how this was much improved over previous TPC versions.
IBM Watson: How it Works and What it Means for Society Beyond Winning Jeopardy!
This week, I am in Orlando, Florida presenting, blogging and tweeting at the IBM Edge conference. The first day began with opening main tent sessions. Deon Newman, IBM VP of Marketing, was the emcee. The four-person [Bella Electric Strings] rocked the house with some electric violins.
Game Change on a Smarter Planet: A New Era in IT
Rod Adkins, IBM Senior VP for the Systems and Technology Group, presented IBM's Smarter Computing strategy. For those not familiar with this, a little context might help.
Back in 2008, IBM launched its corporate-wide strategy called "Smarter Planet", which focused on solving the world's biggest problems through the effective use of Information Technology. To get there, everything needs to be instrumented to monitor and gather information, interconnected with centralized processing, and analyzed through intelligent algorithms.
Over the past few years, this general approach has been made more specific to tackle problems in particular industries. Detailed approaches like Smarter Cities, Smarter Energy, Smarter Education, Smarter Retail, Smarter Water and Smarter Food, are a few examples of this.
As IBM pursued solutions in each of these areas, clients realized they needed some guidance on the underlying IT infrastructure needed to deploy these solutions. Last year, IBM launched the Smarter Computing, which I [explained in great detail in my blog post last March].
Designed for the Data - to be fair, IBM systems have always been designed for the data. When the System/360 first came out, the bulk of data was stored in structured databases, so systems were designed for this. Today, over 80 percent of data is unstructured, not in a database, so the design and approach for systems today must reflect that new reality. For example, Big Data analytics is often used against spreadsheets, documents, social media feeds, and other unstructured sources.
Workload-Optimized Systems - There are two ways to have a workload-optimized system. The first is to start with general purpose components and tune them, and the second is to integrate expertise into the design.
Managed with Cloud technologies - Cloud computing has introduced new levels of standardization, automation and virtualization.
Rod wrapped up his session discussing the IBM PureSystems family of expert-integrated systems that IBM announced in April. This includes the PureFlex infrastructure system and the PureApplication platform system.
A New Approach to Storage
Brian Truskowski, IBM General Manager for System Storage and Networking, presented IBM's new approach to storage to support Smarter Computing environments.
Efficient by Design - Storage needs to be designed for the data, to store it efficiently, and be able to scale in the expected growth, driven by trends such as Big Data analytics.
Self-Optimizing - Storage needs to be self-optimizing for their particular application workloads, to avoid manual performance tuning efforts. Policies to handle Qualities of Service help optimize performance and costs based on business requirements.
Cloud Agile - Storage needs to be part of a virtualized environment, managed by Cloud technologies. This includes working seemlessly in environments with server hypervisors, storage hypervisors, virtual LANs, SANs and tape libraries.
With this new approach, clients will be able to increase competitiveness, while reducing both capital and operational expenses.
Yoni Cohen is the founder and CEO of Snowball Studios. They started with five artists, and grew to 60 people in a few years to take on bigger projects. They produce digital animation for television shows and commercials.
Despite their small size, they have a dedicated "IT" department. In addition to developing in-house tools for the artists to produce animation, they also were tasked to find the best storage solutions. Files storing 3D video can be quite large. After exhausting research into all the storage options, they chose IBM, and complemented this with the Real-Time Compression appliance for their NAS environments.
The results were stunning. A project that took 417GB before took only 148GB. a 64 percent data footprint reduction! He found he got this 3x reduction across his environment.
University of Rochester Medical Center (URMC)
University of Rochester is in New York state, about 60 miles east of Buffalo, and 90 miles from Toronto across Lake Ontario. Six years ago, Rick Haverty joined URMC as the Director of Infrastructure services, managing 130 of the 300 IT personnel at the Medical Center. I met Rick last year, when he presented at the [IBM Storage Innovation Executive Summit] in New York City. Last December, I co-presented with Rick on a session for SONAS at the [Data Center Conference].
URMC has DS8000, DS5000, XIV, SONAS, Storwize V7000 and is in the process of deploying Storwize V7000 Unified. He presented how he has used these for his Vendor Neutral Archive (VNA). For Rick, the IT Infrastructure has become the new "dial tone", everyone expects it to work 100 percent of the time.
For those not familiar with VNA, Rick has 36 different departments, and each was storing archives of their medical images in separate silos of storage. Using software from [Acuo Technologies], he was able to have all 36 different PACS systems store data onto a single storage repository. The side benefit is that all medical images are now readily available to the Electronic Medical Records (EMR) system.
Main Tent for Technical Edge
After the opening session, the folks in Technical Edge moved to a different room for the main tent session. Mike Kuhn, IBM VP of Systems Lab Services, was the emcee. There were three guest speakers:
Clod Barrera, IBM Distinguished Engineer and Chief Technical Strategist for IBM System Storage, presented on storage trends and directions, and how this will influence workload-optimized systems, Cloud computing, Easy Tier, and Active Cloud Engine.
Jeff Jonas, IBM Fellow and Chief Scientist for IBM Entity Analytics, presented "Fantasy Analytics" which explained his work in the Business Analytics. He used "jigsaw puzzles" as an analogy to help explain for the type of work he is researching.
Dan McMillan, Chief Comedy Officer of his own company, was formerly an engineer, but now stand-up comedian. He poked fun at the IT industry, how things have changed since he was an engineer, and his ideal "Universal Business Translator".
Hi everyone! It's Sunday, and I have arrived safely to Orlando, Florida. It actually took me 25 hours to get here, due to mechanical problems on the plane, and an unexpected overnight stay in Chicago. My checked bags unfortunately got misplaced in Chicago, and will hopefully arrive later today.
In past years, IBM ran three separate storage events. One for IT executives, one for technical storage administrators, and one for IBM Business Partners. This year, we have combined all three into one event: IBM Edge. There are three distinct venues: Executive Edge is for the CIOs and IT Directors, Technical Edge for the storage administrators, and Winning Edge is for the IBM Business Partners.
I will be spending most of my time at the Technical Edge events. This year, I was on the review board, and spent much of the last three weeks reviewing a good portion of the 249 presentation topics that will be given this week.
If you have never been to IBM storage events in the past, or it has been awhile since your last one, you can review my blog posts from prior years to get familiar. I have them collected here in my January post [Mark your Calendars - Upcoming Events].
Here is my tentative plan for the week, in case you want to find me. The table is color-coded. White for sessions I am merely attending, and yellow for those sessions that I am presenting or participating as part of a panel.

It's going to be a fun and busy week! I will be tweeting throughout the week. You can follow me on Twitter at [@az990tony]. You can also follow tweets marked #IBMstorage and #IBMedge from others.
This week, Allyson Klein, Director of Technical Leadership Marketing from Intel, interviewed me for the Intel® [Chip Chat podcast] to promote the upcoming [IBM Edge conference] to be held June 4-8 in Orlando, Florida. Intel is a big sponsor of the conference. The podcast is only about 8 minutes long. Enjoy!
Ten years ago, I travelled to New York City with my colleague, Randy Fleenor, to present the latest in IBM tape technology for the 50th Anniversary. On Thursday evening that week, the latest movie in the Star Wars saga, Episode II: Attack of the Clones was just released, and it was being shown using the new Digital Light Projection (DLP) technology just around the corner at the Ziegfeld theater! This movie was the first live-action film to be filmed entirely digital. George Lucas saw that digital video was the future, and started the process moving forward with this film.
I convinced Randy to join me, and we arrived at 11:10pm, the movie was scheduled to start at 11pm, so we figured we had only missed a few previews. We walked into a completely empty lobby. I asked for two tickets for the 11pm show at the ticket counter, and was told it was all sold out, and there was a huge line around the building for all the people waiting to see the 1:00am show, and that we might get in to see the 3:00am show.
Randy and I had meetings on Friday morning, so we were not going to wait in line all night to see a 3am show! Just then, a young man comes out of the theater. He said his girlfriend can't make it, and wanted a refund for his two tickets. I pulled out a twenty-dollar bill, offered to buy them directly at face value, and the theater employees approved the transaction. The seats were front row of the balcony section. By then we had missed all the previews and a short bit of the movie, but that was alright with us.
(FTC Disclosure: I am both an employee and stockholder in IBM. The U.S. Federal Trade Commission may consider this a paid, celebrity endorsement of LTO-5 tapes and the LTFS technology. References to other companies are for illustrative purposes and do not represent an endorsement of their products or services.)
Digital recording is ideal for all types of video, including movies, television, and commercial advertisements.
The latest excitement is over IBM's Linear Tape File System™ (LTFS), which IBM donated to the IT industry as open source so that everyone in the world can benefit. This allows tape cartridges to be treated like USB memory sticks, the ultimate in portability of data. It is supported for Windows, Mac OS, and Linux, and already well embraced by the Media-and-Entertainment (M&E) industry.
"The move to IBM technology has helped the network shrink its archive from 1,507 to just 388 square feet, representing dramatic systems and energy-cost savings."
"AlphaTV has been broadcasting since 1996, creating and storing all forms of video entertainment, from soap operas and documentaries, to movies and sporting events, and creating a vast video archive along the way. Initially, AlphaTV archived its programming on Sony Beta SP format video cassettes that stored up to 90 minutes of content. Not long after, in need of storage that offered greater density, it turned to DVCPRO format videos that stored up to 120 minutes. But even that format was not allowing the network to keep pace with its ballooning archive, a storage infrastructure that by 2011 spanned more than 1,507 square feet."
"'A Greek TV series stored on 100 DVCPRO tapes took up four shelves in our library, whereas on LTO-5 cartridge now takes up the space of a deck of playing cards,' Constantinos Colombus, chief technology officer at AlphaTV, said in a statement."
"IBM LTFS, an intuitive and graphical file system that provides direct access to data on LTO 5 drives, has enabled AlphaTV to manage, move and share video files much like they can with disk-management systems, by simply dragging and dropping. As a result, file management is easier to do and far more efficient, said Colombus."
To prepare for this anniversary, I spoke with Brad Johns, of [Brad Johns Consulting]. Brad was head of IBM tape marketing for a while, and ran tape customer councils to gather feedback from our largest customers. Brad was my mentor in marketing at IBM from 2003-2007 and has since retired from IBM to start his own consulting practice.
The comparison was made between Crossroad Systems' Strongbox® with Enterprise tape library, LTO-5 tapes using LTFS, versus a unified disk storage system offering NAS protocols on high-capacity 3TB drives. The findings: the tape-based archive had nearly 80 percent lower TCO than the disk-based solution!
You don't have to be in the middle of the Greek economy to real that is a good value!
Well it's Tuesday again, and you know what that means.. IBM announcements! Today, IBM announces that next Monday marks the 60th anniversary of first commercial digital tape storage system! I am on the East coast this week visiting clients, but plan to be back in Tucson in time for the cake and fireworks next Monday.
1925 - masking tape (which 3M sold under its newly announced Scotch® brand)
1930 - clear cellulose-based tape (today, when people say Scotch tape, they usually are referring to the cellulose version)
1935 - Allgemeine Elektrizitatsgesellschaft (AEG) presents Magnetophon K1, audio recording on analog tape
1942 - Duct tape
1947 - Bing Crosby adopts audio recording for his radio program. This eliminated him doing the same program live twice per day, perhaps the first example of using technology for "deduplication".
According to the IBM Archives the [IBM 726 tape drive was formally announced May 21, 1952]. It was the size of a refrigerator, and the tape reel was the size of a large pizza. The next time you pull a frozen pizza from your fridge, you can remember this month's celebration!
When I first joined IBM in 1986, there were three kinds of IBM tape. The round reel called 3420, and the square cartridge called 3480, and the tubes that contained a wide swath of tape stored in honeycomb shelves called the [IBM 3850 Mass Storage System].
My first job at IBM was to work on DFHSM, which was specifically started in 1977 to manage the IBM 3850, and later renamed to the DFSMShsm component of the DFSMS element of the z/OS operating system. This software was instrumental in keeping disk and tape at high 80-95 percent utilization rates on mainframe servers.
While visiting a client in Detroit, the client loved their StorageTek tape automation silo, but didn't care for the StorageTek drives inside were incompatible with IBM formats. They wanted to put IBM drives into the StorageTek silos. I agreed it was a good idea, and brought this back to the attention of development. In a contentious meeting with management and engineers, I presented this feedback from the client.
Everyone in the room said IBM couldn't do that. I asked "Why not?" The software engineers I spoke to already said they could support it. With StorageTek at the brink of Chapter 11 bankruptcy, I argued that IBM drives in their tape automation would ease the transition of our mainframe customers to an all-IBM environment.
Was the reason related to business/legal concerns, or was their a hardware issue? It turned out to be a little of both. On the business side, IBM had to agree to work with StorageTek on service and support to its mutual clients in mixed environments. On the technical side, the drive had to be tilted 12 degrees to line up with the robotic hand. A few years later, the IBM silo-compatible 3592 drive was commercially available.
Rather than put StorageTek completely out of business, it had the opposite effect. Now that IBM drives can be put in StorageTek libraries, everyone wanted one, basically bringing StorageTek back to life. This forced IBM to offer its own tape automation libraries.
In 1993, I filed my first patent. It was for the RECYCLE function in DFHSM to consolidate valid data from partial tapes to fresh new tapes. Before my patent, the RECYCLE function selected tapes alphabetically, by volume serial (VOLSER). My patent evaluated all tapes based on how full they were, and sorted them least-full to most-full, to maximize the return of cartridges.
Different tape cartridges can hold different amounts of data, especially with different formats on the same media type, with or without compression, so calculating the percentage full turned out to be a tricky algorithm that continues to be used in mainframe environments today.
The patent was popular for cross-licensing, and IBM has since filed additional patents for this invention in other countries to further increase its license revenue for intellectual property.
In 1997, IBM launched the IBM 3494 Virtual Tape Server (VTS), the first virtual tape storage device, blending disk and tape to optimal effect. This was based off the IBM 3850 Mass Storage Systems, which was the first virtual disk system, that used 3380 disk and tape to emulate the older 3350 disk systems.
In the VTS, tape volume images would be emulated as files on a disk system, then later moved to physical tape. We would call the disk the "Tape Volume Cache", and use caching algorithms to decide how long to keep data in cache, versus destage to tape. However, there were only a few tape drives, and sometimes when the VTS was busy, there were no tape drives available to destage the older images, and the cache would fill up.
I had already solved this problem in DFHSM, with a function called pre-migration. The idea was to pre-emptively copy data to tape, but leave it also on disk, so that when it needed to be destaged, all we had to do was delete the disk copy and activate the tape copy. We patented using this idea for the VTS, and it is still used in the successor models of IBM Sysem Storage TS7740 virtual tape libraries today.
Today, tape continues to be the least expensive storage medium, about 15 to 25 times less expensive, dollar-per-GB, than disk technologies. A dollar of today's LTO-5 tape can hold 22 days worth of MP3 music at 192 Kbps recording. A full TS1140 tape cartridge can hold 2 million copies of the book "War and Peace".
(If you have not read the book, Woody Allen took a speed reading course and read the entire novel in just 20 minutes. He summed up the novel in three words: "It involves Russia." By comparison, in the same 20 minutes, at 650MB/sec, the TS1140 drive can read this novel over and over 390,000 times.)
If you have your own "war stories" about tape, I would love to hear them, please consider posting a comment below.
Those that prefer to work with one-stop shopping of an IT Supermarket, with companies like IBM, HP and Dell who offer a complete set of servers, storage, switches, software and services, what we call "The Five S's".
Those that perfer shopping for components at individual specialty shops, like butchers, bakers, and candlestick makers, hoping that this singular focus means the products are best-of-breed in the market. Companies like HDS for disk, Quantum for tape, and Symantec for software come to mind.
My how the IT landscape for vendors has evolved in just the past five years! Cisco starts to sell servers, and enters a "mini-mall" alliance with EMC and VMware to offer vBlock integrated stack of server, storage and switches with VMware as the software hypervisor. For those not familiar with the concept of mini-malls, these are typically rows of specialty shops. A shopper can park their car once, and do all their shopping from the various shops in the mini-mall. Not quite "one-stop" shopping of a supermarket, but tries to address the same need.
("Who do I call when it breaks?" -- The three companies formed a puppet company, the Virtual Computing Environment company, or VCE, to help answer that question!)
Among the many things IBM has learned in its 100+ years of experience, it is that clients want choices. Cisco figured this out also, and partnered with NetApp to offer the aptly-named FlexPod reference architecture. In effect, Cisco has two boyfriends, when she is with EMC, it is called a Vblock, and when she is with NetApp, it is called a FlexPod. I was lucky enough to find this graphic to help explain the three-way love triangle.
Did this move put a strain on the relationship between Cisco and EMC? Last month, EMC announced VSPEX, a FlexPod-like approach that provides a choice of servers, and some leeway for resellers to make choices to fit client needs better. Why limit yourself to Cisco servers, when IBM and HP servers are better? Is this an admission that Vblock has failed, and that VSPEX is the new way of doing things? No, I suspect it is just EMC's way to strike back at both Cisco and NetApp in what many are calling the "Stack Wars". (See [The Stack Wars have Begun!], [What is the Enterprise Stack?], or [The Fight for the Fully Virtualized Data Center] for more on this.)
(FTC Disclosure: I am both an employee and shareholder of IBM, so the U.S. Federal Trade Commission may consider this post a paid, celebrity endorsement of the IBM PureFlex system. IBM has working relationships with Cisco, NetApp, and Quantum. I was not paid to mention, nor have I any financial interest in, any of the other companies mentioned in this blog post. )
Last month, IBM announced its new PureSystems family, ushering in a [new era in computing]. I invite you all to check out the many "Paterns of Expertise" available at the [IBM PureSystems Centre]. This is like an "app store" for the data center, and what I feel truly differentiates IBM's offerings from the rest.
The trend is obvious. Clients who previously purchased from specialty shops are discovering the cost and complexity of building workable systems from piece-parts from separate vendors has proven expensive and challenging. IBM PureFlex™ systems eliminate a lot of the complexity and effort, but still offer plenty of flexibility, choice of server processor types, choice of server and storage hypervisors, and choice of various operating systems.
There is still time to enroll for [IBM Edge], a conference focused on storage, to be held June 4-8 in Orlando, Florida. There is an early-bird discount until May 6!
I will be there all week! Here are the seven sessions I will be presenting at the Technical Edge side of the event:
Understanding Your Options for Storing Archive Data to Meet Compliance Challenges
This session will cover the IBM software and hardware solutions that your organization can use to store archive data, including features like immutability, Write-Once-Read-Many (WORM) technology and Non-Erasable, Non-Rewriteable (NENR) enforcement. The discussion will include high-level concepts like chronological and event-based retention, litigation hold and release, as well as an overview of the products and solutions from IBM that you can deploy today.
IBM Watson: How it Works and What it Means for Society Beyond Winning Jeopardy!
In 2011, the IBM Watson computer was able to beat the top-earning human winners on the trivia game-show “Jeopardy!” As I was the author of [How to Build Your Own Watson Junior in Your Basement], I have been asked to explain how the IBM Watson system was put together, how it works, and what examples of text mining and big data analytics means for society as we apply technology to meet tomorrow's challenges.
Using Social Media for IBM System Storage - Birds of a Feather
I will be moderating this Birds of a Feather, or BOF, session that will bring together a Q&A panel of experts on how social media can be leveraged to help you do your job, get the information you need to solve problems, and share your knowledge with others.
Data Footprint Reduction: Understanding IBM Storage Efficiency Options
Data Footprint Reduction is the catch-all term for a variety of technologies designed to help reduce storage costs. In this session, I will cover thin provisioning, space-efficient copies, deduplication and compression technologies, and describe the IBM storage products that provide these capabilities.
IBM's Storage Strategy in the Smarter Computing Era
Confused about IBM's new initiatives for Big Data analytics, Workload Optimized Systems, and Cloud Computing? This session will explain it all, and how IBM's strategy for its various storage products and solutions fit into these overall themes.
IBM SONAS and the IBM Cloud Storage Taxonomy
Confused over the different types of cloud storage? IBM's scale-out Network Attached Storage (SONAS) can be used in a variety of use cases. This session will provide an overview of IBM's SONAS solution, provide an update on the latest features and functions recently announced, and explain how it can be deployed in various private, public and hybrid cloud environments.
IBM Tivoli Storage Productivity Center Overview and Update
IBM has enhanced its premier storage infrastructure management tool: IBM Tivoli Storage Productivity Center. This session will provide both an overview of the product, and explain the latest features and functions recently announced.
This week, I am in beautiful Sao Paulo, Brazil, teaching Top Gun class to IBM Business Partners and sales reps. Traditionally, we have "Tape Thursday" where we focus on our tape systems, from tape drives, to physical and virtual tape libraries. IBM is the number #1 tape vendor, and has been for the past eight years.
(The alliteration doesn't translate well here in Brazil. The Portuguese word for tape is "fita", and Thursday here is "quinta-feira", but "fita-quinta-feira" just doesn't have the same ring to it.)
In the class, we discussed how to handle common misperceptions and myths about tape. Here are a few examples:
Myth 1: Tape processing is manually intensive
In my July 2007 blog post [Times a Million], I coined the phrase "Laptop Mentality" to describe the problem most people have dealing with data center decisions. Many folks extend linearly their experiences using their PCs, workstations or laptops to apply to the data center, unable to comprehend large numbers or solutions that take advantage of the economies of scale.
For many, the only experience dealing with tape was manual. In the 1980s, we made "mix tapes" on little cassettes, and in the 1990s we recorded our favorite television shows on VHS tapes in the VCR. Today, we have playlists on flash or disk-based music players, and record TV shows on disk-based video recorders like Tivo. The conclusion is that tapes are manual, and disk are not.
Manual processing of tapes ended in 1987, with the introduction of a silo-like tape library from StorageTek. IBM quickly responded with its own IBM 3495 Tape Library Data Server in 1992. Today, clients have many tape automation choices, from the smallest IBM TS2900 Tape Autoloader that has one drive and nine cartridges, all the way to the largest IBM TS3500 multiple-library shuttle complex that can hold exabytes of data. These tape automation systems eliminate most of the manual handling of cartridges in day-to-day operations.
Myth 2: Tape media is less reliable than disk media
For any storage media to be unreliable is to return the wrong information that is different than what was originally stored. There are only two ways for this to happen: if you write a "zero" but read back a "one", or write a "one" and read a "zero". This is called a bit error. Every storage media has a "bit error rate" that is the average likelihood for some large amount of data written.
According to the latest [LTO Bit Error rates, 2012 March], today's tape expects only 1 bit error per 10E17 bits written (about 100 Petabytes). This is 10 times more reliable than Enterprise SAS disk (1 bit per 10E16), and 100 times more reliable than Enterprise-class SATA disk (1 bit per 10E15).
Tape is the media used in "black boxes" for airplanes. When an airplane crashes, the black box is retrieved and used to investigate the causes of the crash. In 1986, the Space Shuttle Challenger exploded 73 seconds after take-off. The tapes in the black box sat on the ocean floor for six weeks before being recovered. Amazingly, IBM was able to successfully restore [90 percent of the block data, and 100 percent of voice data].
Analysts are quite upset when they are quoted out of context, but in this case, Gartner never said anything closely similar to this. Nor did the other analysts that Curtis investigated for similar claims. What Garnter did say was that disk provides an attractive alternative storage media for backup which can increase the performance of the recovery process.
Back in the 1990s, Savur Rao and I developed a patent to help backup DB2 for z/OS by using the FlashCopy feature of IBM's high-end disk system. The software method to coordinate the FlashCopy snapshots with the database application and maintain multiple versions was implemented in the DFSMShsm component of DFSMS. A few years later, this was part of a set of patents IBM cross-licensed to Microsoft for them to implement a similar software for Windows called Data Protection Manager (DPM). IBM has since introduced its own version for distributed systems called IBM Tivoli FlashCopy Manager that runs not just on Windows, but also AIX, Linux, HP-UX and Solaris operating systems.
Curtis suspects the "71 percent" citation may have been propogated by an ambitious product manager of Microsoft's Data Protection Manager, back in 2006, perhaps to help drive up business to their new disk-based backup product. Certainly, Microsoft was not the only vendor to disparage tape in this manner.
A few years ago, an [EMC failure brought down the State of Virginia] due to not just a component failure it its production disk system, but then made it worse by failing to recover from the disk-based remote mirror copy. Fortunately, the data was able to be restored from tape over the next four days. If you wonder why nobody at EMC says "Tape is Dead" anymore, perhaps it is because tape saved their butts that week.
(FTC Disclosure: I work for IBM and this post can be considered a paid, celebrity endorsement for all of the IBM tape and software products mentioned on this post. I own shares of stock in both IBM and Google, and use Google's Gmail for my personal email, as well as many other Google services. While IBM, Google and Microsoft can be considered competitors to each other in some areas, IBM has working relationships with both companies on various projects. References in this post to other companies like EMC are merely to provide illustrative examples only, based on publicly available information. IBM is part of the Linear Tape Open (LTO) consortium.)
Myth 4: Vendors and Manufacturers are no longer investing in tape technology
IBM and others are still investing Research and Development (R&D) dollars to improve tape technology. What people don't realize is that much of the R&D spent on magnetic media can be applied across both disk and tape, such as IBM's development of the Giant Magnetoresistance read/write head, or [GMR] for short.
Most recently, IBM made another major advancement with tape with the introduction of the Linear Tape File Systems (LTFS). This allows greater portability to share data between users, and between companies, but treating tape cartridges much like USB memory sticks or pen drives. You can read more in my post [IBM and Fox win an Emmy for LTFS technology]!
Next month, IBM celebrates the 60th anniversary for tape. It is good to see that tape continues to be a vibrant part of the IT industry, and to IBM's storage business!
This week I'm in Argentina, teaching IBM Business Partners and sales reps about the latest System Storage products. Encouraged by my success on my Digital IBMer tour last month in Europe, I decided to get a SIM chip for my smartphone here in Buenos Aires.
I did my homework. There are three major mobile service providers that offer pre-paid GSM-based SIM chips: Claro, Movistar, and Personal. I arrived on Sunday morning, but thanks to the local [blue laws], none of them were open. I was able to walk around and find retail outlets for each within blocks of my hotel.
All three offer voice and SMS text messaging, but online reviews indicated that Movistar offered the best data plan. I was there at 9:30am sharp, the moment the Movistar store opened Monday morning. The lovely young lady behind the counter was quite helpful. She put the SIM chip in my phone, but then told me it might be an hour or two before it was activated. I would receive an SMS text message welcoming me to the Movistar network. She provided my new 12-digit phone number, along with instructions on how to check my balance (*444) or call for technical assistance (*611).
(FTC Disclosure: even though I am not in the United States as I write this, the U.S. Federal Trade Commission rules require that I mention that this blog post is not intended as a paid or celebrity endorsement for any of the cellphone service providers mentioned. I work for IBM, and this post is based entirely on my personal experience.)
Why not just use international roaming available on my US plan? International roaming is quite expensive! I made the mistake of uploading three hi-res photos to Flickr last year in New Zealand to discover this the hard way. Here is a comparison chart:
Voice calls (per minute)
$2.80 pesos (about $0.64 USD)
SMS text (per message sent)
$0.90 pesos (about $0.20 USD)
$10.00 pesos for 1GB across 2 days (about $2.27 USD)
(If your spouse or significant other threatens to leave you if you don't call her every day while out of the country, remind her that divorce attorneys are less expensive than these international roaming rates! Fortunately, all of my friends and family know this and are quite understanding if they don't here from me as often as they would like.)
The SIM chip cost only 30 pesos (about seven bucks). Normally, SIM chips come without credit, but their current promotion included 20 pesos credit for voice calls (enough for 7 minutes of talking), and 200 free SMS text messages.
Six hours later, my phone still was not yet activated. I returned to the store Monday afternoon to ask what was going on. She decided the chip must be bad, gave me a second one, and assigned me a new phone number. I would then have to wait again another hour or two for the welcome message.
Monday evening, a grey window pops up, "Bienvenidos a Movistar" so I thought it was activated, but it wasn't exactly the SMS text message the young lady told me would happen. Sure enough, neither *444 nor *611 worked, giving me voice responses that my phone is not yet activated, and please wait another hour.
Tuesday morning, I am back at the Movistar outlet. The young lady was not happy to see me. She confirmed my second chip was not yet activated, but felt she did nothing wrong. She insisted the problem was either with my phone, or with the Movistar main office, but that she did everything correctly by the book.
(I realize that the sales clerks at these outlet stores don't have a Ph.D. in digital telephony or electrical engineering. I was not angry, nor trying to blame her individually for all of the problems we encountered. Getting a smartphone manufactured in South Korea for the US market to work in Argentina is challenging enough. Given all the difficulties I had last month in Europe, I know it is not limited to Latin America.)
Either way, I told her, if we can't get my phone working, I would like my 30 pesos refunded and promised she would never see me again.
Her response was classic. She would rather not-see me-again because I was delighted with the Movistar service, rather than not-see me-again because we were unable to get it working. She offered to contact the main office to figure out what was going on, and that I should come back in an hour or two. She did not want to lose my business, nor have me go to one of her two main competitors. Now that's customer service!
Tuesday afternoon, I return. She now was instructed on how to do some basic problem determination. We put my new SIM chip into a test phone, and confirmed it was not my phone having problems. The chip did not work in the test phone either. She called the main office, and they were able to activate the chip in the test phone, and then she transferred the chip back to my phone. I asked her to please call my new phone number to confirm it was now working, and I was able to send a quick text message to confirm that was also working. The *444 indcated that my balance was now down to 19.29 pesos. Apparently, it cost me 71 centavos to receive her phone call.
(Just as we were wrapping up, a young man walks in with his phone wanting a SIM chip. None of the Movistar staff spoke English, he did not speak Spanish, but luckily I speak both fluently and was able to translate.
First, we confirmed his phone was still locked, and that he would need to contact his AT&T provider to get an unlock code. He should then come back with the unlock code and his passport to then buy the chip. He didn't understand why Movistar needed his passport for a pre-paid plan, so I had to explain to him at length Argentinian law, the Denied Parties List, the ongoing war against terror and drug trafficking, and how he would have to agree to their Terms and Conditions to use their service, even if there is no ongoing monthly service contract.
He thanked me, promised to return with both his unlock code and passport, and told me my English was "quite good"!)
The next step was to activate my data plan. For this, I would need to buy additional credit. Scratch cards to add credit to your pre-paid phone, referred to locally as "Tarjeta de Recarga", come in 20 and 30-peso denomnations, but are not sold at the Movistar outlet. Instead, the young lady told me to get one at any kiosk or corner convenience store.
As it turns out, not every convenience store offers these cards for Movistar, but after a few blocks, I was able to find one that did. The process is simple: call *444, follow the Spanish-language prompts, scratch off the back of the card, and enter the 16-digit code. I bought a 20-peso card (about $4.50 USD), followed the procedure, and got my confirmation text, indicating that I qualified for 10 extra pesos as a gift for being a new customer, so my new balance was now $49.29 pesos. Woo-hoo!
Now that my phone was armed with enough credit, all I had to do was send an SMS text message containing the word "Datos" to the Movistar phone number 2345. A text message response indicated my data plan was now active. I will have to do this every other day, as the plan is 1GB per 2-day period, but I have enough credit to last me the rest of the week here. To get my phone to detect the new status, I had to turn on data packet traffic, configure and validate the Access Point Name (APN) information, then reboot the phone.
The data plan service is based on the General Packet Radio Service [GPRS] protocol. GPRS is a best-effort service, resulting in variable throughput and latency that depends on the number of other users sharing the service concurrently. Speeds are comparable to dial-up rates, 56 to 114 Kbps.
For those of us spoiled on T-Mobile's 4G speeds in the USA, GPRS is terribly slow. But that's OK. I doubt I will go over the 1GB limit. Overall, I am quite pleased with my success. My phone is fully functional for the week, and all for less than the cost of a single glass of Malbec in the Hilton lobby bar!
Well, it's Wednesday, and you know what that means... IBM Announcements!
(Actually most IBM announcements are on Tuesdays, but IBM gave me extra time to recover from my trip to Europe!)
Today, IBM announced [IBM PureSystems], a new family of expert-integrated systems that combine storage, servers, networking, and software, based on IBM's decades of experience in the IT industry. You can register for the [Launch Event] today (April 11) at 2pm EDT, and download the companion "Integrated Expertise" event app for Apple, Android or Blackberry smartphones.
(If you are thinking, "Hey, wait a minute, hasn't this been done before?" you are not alone. Yes, IBM introduced the System/360 back in 1964, and the AS/400 back in 1988, so today's announcement is on scheduled for this 24-year cycle. Based on IBM's past success in this area, others have followed, most recently, Oracle, HP and Cisco.)
Initially, there are two offerings:
IBM PureFlex™ System
IBM PureFlex is like IaaS-in-a-box, allowing you to manage the system as a pool of virtual resources. It can be used for private cloud deployments, hybrid cloud deployments, or by service providers to offer public cloud solutions. IBM drinks its own champagne, and will have no problem integrating these into its [IBM SmartCloud] offerings.
To simplify ordering, the IBM PureFlex comes in three tee-shirt sizes: Express, Standard and Enterprise.
IBM PureFlex is based on a 10U-high, 19-inch wide, standard rack-mountable chassis that holds 14 bays, organized in a 7 by 2 matrix. Unlike BladeCenter where blades are inserted vertically, the IBM PureFlex nodes are horizontal. Some of the nodes take up a single bay (half-wide), but a few are full-wide, take up two bays, the full 19-inch width of the chassis. Compute and storage snap in the front, while power supplies, fans, and networking snap in the back. You can fit up to four chassis in a standard 42U rack.
Unlike competitive offerings, IBM does not limit you to x86 architectures. Both x86 and POWER-based compute nodes can be mixed into a single chassis. Out of the box, the IBM PureFlex supports four operating systems (AIX, IBM i, Linux and Windows), four server hypervisors (Hyper-V, Linux KVM, PowerVM, and VMware), and two storage hypervisors (SAN Volume Controller and Storwize V7000).
There are a variety of storage options for this. IBM will offer SSD and HDD inside the compute nodes themselves, direct-attached storage nodes, and an integrated version of the Storwize V7000 disk system. Of course, every IBM System Storage product is supported as external storage. Since Storwize V7000 and SAN Volume Controller support external virtualization, many non-IBM devices will be supported automatically as well.
Networking is also optimized, with options for 10Gb and 40Gb Ethernet/FCoE, 40Gb and 56Gb Infiniband, 8Gbps and 16Gbps Fibre Channel. Much of the networking traffic can be handled within the chassis, to minimize traffic on external switches and directors.
For management, IBM offers the Flex System Manager, that allows you to manage all the resources from a single pane of glass. The goal is to greatly simplify the IT lifecycle experience of procurement, installation, deployment and maintenance.
IBM PureApplication™ System
IBM PureApplication is like PaaS-in-a-box. Based on the IBM PureFlex infrastructure, the IBM PureApplication adds additional software layers focused on transactional web, business logic, and database workloads. Initially, it will offer two platforms: Linux platform based on x86 processors, Linux KVM and Red Hat Enterprise Linux (RHEL); and a UNIX platform based on POWER7 processors, PowerVM and AIX operating system. It will be offered in four tee-shirt sizes (small, medium, large and extra large).
In addition to having IBM's middleware like DB2 and WebSphere optimized for this platform, over 600 companies will announce this week that they will support and participate in the IBM PureSystems ecosystem as well. Already, there are 150 "Patterns of Expertise" ready to deploy from IBM PureSystem Centre, a kind of a "data center app store", borrowing an idea used today with smartphones.
By packaging applications in this manner, workloads can easily shift between private, hybrid and public clouds.
If you are unhappy with the inflexibility of your VCE Vblock, HP Integrity, or Oracle ExaLogic, talk to your local IBM Business Partner or Sales Representative. We might be able to buy your boat anchor off your hands, as part of an IBM PureSystems sale, with an attractive IBM Global Financing plan.
Well, another week has gone by, and I am now back from my grand "Digital IBMer" trip to Europe! Here's what the second week involved.
Prague, Czech Republic
The cold and rainy weather followed us from Berlin! We were able to go to the old castle, light a candle for a friend in the hospital at the St. Vitus Cathedral, and walk across the famous Charles Bridge to go see the Astronomical Clock.
We stayed in the "Blind Eye" hostel, which was an awesome place, with friendly and helpful staff.
The weather was much nicer in Vienna, giving us a chance to see the palace and surrounding gardens. In front of the palace was an "Easter Market" where booths sold various arts and crafts, as well as delicious food and drink. I had a slab of ham, a pile of mustard, and a cup of [Glühwein], a hot drink made from mulled red wine.
I met several people at the hostel Ruthensteiner, from the UK, Argentina and Spain, and we all went out drinking at a Polish pub down the street.
The next morning we walked through the city center. We learned that this week leading up to Easter Sunday--known as Semana Santa in some countries--was also "Spring Break" for many students, which explained why we were starting to have a harder time finding hostels to stay at.
Salzburg means "City of Salt" and the salt mines in the area allowed the landlords to get rich. If you have seen the movie [The Sound of Music] then you already know how beautiful Salzburg is. The castle was incredible, and was used for military purposes until 1861, when it was opened to the public.
Inside the castle is an awesome museum for [Marionettes], which are puppets controlled from above by strings, still used in productions today.
Unable to find a youth hostel, we stayed in the lovely Alderhof Pension Hotel. It was quiet and well-situated near the main train station.
At Munich, we decide to take [Sandeman's "New Europe" free guided city walking tour]. It is free, in that the tour guides work entirely for tips. Tours were available in English or Spanish. This was about three hours long, and we gladly tipped heavily for such an informational tour of everything from the Glockenspiel to the Residenz palace. One stop on the tour was to see the main "Beer Garden" where rows and rows of people enjoying beer in the beautiful weather.
While in Munich, I was invited to see a sneak preview of the movie [Iron Sky], a campy, politically-incorrect, low-budget sci-fi comedy made in Europe with a mix of English language dialogue, and German language dialogue with English subtitles. The year is 2018, a woman that looks a lot like Sarah Palin is now president of the United States, and Nazis that have set up a moon-based space station back in 1945 are ready to attack. If you liked the movies "White Chicks" and "Battlefield Earth", then you might enjoy this one as well. You may need to know a bit about the history of the third Reich, the operas of Wagner, and the movie [The Great Dictator] by Charlie Chaplin, to make sense of some of the inside jokes.
We visited Heidelberg on [Good Friday and the place was a ghost town. The streets were nearly empty, and the tourist shops didn't open until 10am. Despite this, we managed to take the funicular train up the mountain to visit the castle, visit an interesting Pharmacy Museum, see the world's largest wine barrel, have a traditional German lunch, and take pictures of the old stone bridge.
We got back to Frankfurt and left Saturday morning to fly back to the United States.
We managed to visit 11 cities in six different countries over the course of 16 days. I was able to learn quite a lot about the use of mobile apps to book hotels and find the appropriate trains to get around each country, take advantage of social media to determine what to see and do, and the use of cloud to store my photos, videos and notes along the way.
"This week, IBM is launching a companywide effort to build the digital eminence of all IBMers. The goal is to arm you with the tools and knowledge to effectively use emerging technologies -- such as social, mobile, and cloud computing -- for strategic advantage."
This is how Rod Adkins, IBM Senior VP of Systems Technology Group, and my sixth-line manager, starts a memo to declare April "Digital IBMer awareness month". I am not sure if this is just for this April, or every April going forward. Included with this is a set of ten guidelines to improve CyberSecurity:
In honor of this, I will be spending the next two weeks traveling through Europe. Instead of bringing a large suitcase and my laptop, I have decided instead to only take:
The clothes I am wearing on the plane
A heavy jacket with lots of pockets
A backpack with 15 pounds of clothes
A hipsack with my smartphone, digital camera, MP3 player and all the related adapters, chargers and cables
My smartphone uses a GSM chip, so I should be able to get a European SIM when I arrive. I have not booked any hotels, tours, or transportation. Instead, I will rely on social media and cloud computing to take care of things on a daily basis.
(Why only 15 pounds of clothing? I just had major surgery two weeks ago, and my doctor advised me not to lift more than 15 pounds for the next six weeks!)
I plan to have a series of blog posts documenting what I learn from this trip. For those who want to follow along, I will be tweeting from @az990tony. You do not need a Twitter account to read my tweets. You can read them directly from [http://twitter.com/#!/az990tony].
I can't remember the last time I have gone this long without the comforts of my laptop or desktop, so it will be interesting how it works out!
Five years ago, I sprayed coffee all over my screen from something I read on a blog post from fellow blogger Hu Yoshida from HDS. You can read what cased my reaction in my now infamous post [Hu Yoshida should know better]. Subsequently, over the years, I have disagreed with Hu on a variety of of topics, as documented in my 2010 blog post [Hu Yoshida Does It Again].
(Apparently, I am not alone, as the process of spraying one's coffee onto one's computer screen while reading other blog posts has been referred to as "Pulling a Tony" or "Doing a Tony" by other bloggers!)
Fortunately, my IBM colleague David Sacks doesn't drink coffee. Last month, David noticed that Hu had posted a graph in a recent blog entry titled [Additional Storage Performance Efficiencies for Mainframes], comparing the performance of HDS's Virtual Storage Platform (VSP) to IBM's DS8000.
For those not familiar with disk performance graphs, flatter is better, lower response time and larger IOPS are always desired. This graph implies that the HDS disk system is astonishingly faster than IBM's DS8000 series disk system. Certainly, the HDS VSP qualifies as a member of the elite [Super High-End club] with impressive SPC benchmark numbers, and is generally recognized as a device that works in IBM mainframe environments. But this new comparison graph is just ridiculous!
(Note: While SPC benchmarks are useful for making purchase decisions, different disk systems respond differently to different workloads. As the former lead architect of DFSMS for z/OS, I am often brought in to consult on mainframe performance issues in complex situations. Several times, we have fixed performance problems for our mainframe clients by replacing their HDS systems with IBM DS8000 series!)
Since Hu's blog entry contained very little information about the performance test used to generate the graph, David submitted a comment directly to Hu's blog asking a few simple questions to help IBM and Hu's readers determine whether the test was fair. Here is David's comment as submitted:
(Disclosure: I work for IBM. This comment is my own.)
I was quite surprised by the performance shown for the IBM DS8000 in the graph in your blog. Unfortunately, you provided very little detail about the benchmark. That makes it rather difficult (to say the least) to identify factors behind the results shown and to determine whether the comparison was a fair one.
Of the little information provided, an attribute that somewhat stands out is that the test appears to be limited to a single volume at least, that's my interpretation of "LDEV: 1*3390-3"? IBM's internal tests for this kind of case show far better response time and I/Os per second than the graph you published.
Here are a few examples of details you could provide to help readers determine whether the benchmark was fair and whether the results have any relevance to their environment.
What DS8000 model was the test run on? (the DS8000 is a family of systems with generations going back 8 years. The latest and fastest model is the DS8800.)
What were the hardware and software configurations of the DS8000 and VSP systems, including the number and speed of performance-related components?
What were the I/O workload characteristics (e.g., read:write ratio and block size(s))?
What was the data capacity of each volume? (Allocated and used capacity.)
What were the cache sizes and cache hit ratios for each system? (The average I/O response times under 1.5 milliseconds for each system imply the cache hit ratios were relatively high.)
How many physical drives were volumes striped across in each system?"
Unlike my blog on IBM, HDS bloggers like Hu are allowed to reject or deny comments before they appear on his blog post. We were disappointed that HDS never posted David's comment nor responded to it. That certainly raises questions about the quality of the comparison.
So, perhaps this is yet another case of [Hitachi Math], a phrase coined by fellow blogger Barry Burke from EMC back in 2007 in reference to outlandish HDS claims. My earliest mention was in my blog post [Not letting the Wookie Win].
By the way, since the test was about z/OS Extended Address Volumes (EAV), it is worth mentioning that IBM's DS8700 and DS8800 support 3390 volume capacities up to 1 TB each, while the HDS VSP is limited to only 223 GB per volume. Larger volume capacities help support ease-of-growth and help reduce the number of volumes storage administrators need to manage; that's just one example of how the DS8000 series continues to provide the best storage system support for z/OS environments.
Personally, I am all for running both IBM and HDS boxes side-by-side and publishing the methodology, the workload characteristics, the configuration details, and the results. Sunshine is always the best disinfectant!
Did you miss IBM's Pulse 2012 conference? So did I. Last month, I told you all to [mark your calendars], but wasn't sure if I would be there myself or not.
I was invited to attend Pulse this year, but had to instead go to the Hospital for surgery and spend the week recovering. I thought I made that clear on my last post that I would be spending [the week on my back, with a tube in my arm], but apparently, people missed that subtlety.
The tube was actually connected to the back of my left hand, and I was tempted to take pictures of the entire process, but decided not to, since my gown had no pockets to hold my camera. Perhaps it is better it went undocumented. The less you see of the inner workings of a hospital, as a patient, the better. The whole things was quite a blur.
Despite a few mishaps, I managed to survive the week. Many thanks to Hilda, Dina, Crystal, Marcie, Mike, Joe, Ryan, Sue, Debra, Donna, Modrechai, and the rest of the fine medical staff at St. Joseph's for their hospitality! And of course, many thanks to Mo, my parents and sisters for helping me through the recovery!
Fortunately, for those like me who were unable to go to Las Vegas last week, there is the [IBM Pulse2012 Video Library] with highlights of the keynotes and other sessions during the week.
This week is IBM Pulse2012 conference in Las Vegas. I am not there, for medial reasons this time. While my colleagues will be spending this week sipping Margaritas and enjoying the music in between inspiring technical sessions, I will be flat on my back, getting all my nutrients from a tube connected to my arm, listening to the hospital equivalent of [Muzak].
"IBM Pulse 2012 ‘s opening keynote talked about the realities of cloud as a delivery model – without the ‘private-‘, or the ‘public-‘, or even the quotes or capitalization of “The Cloud.” It was IBM’s perspective on what IBM knows better than most, how to deliver enterprise IT services that map to strategic business goals."
"In contrast to talking about ‘data-center/cloud’ stuff and then later about ‘consumerization-of-IT’ stuff , IBM’s core message was how mobility was in many ways driving cloud evolution."
"...cloud-based delivery was ‘more than just virtualization’"
"...the US Dept of Labor stating that jobs related to technology are forecast to be among the fastest growing segment thru 2018."
Hopefully, this post will hold you over until I regain consciousness.
Most readers know thta Tucson is home of one of the largest collections of world-renowned experts on IT storage. But what you may not know, is that Tucson is also the home of experts for optical sciences. This week, I was part of a delegation of IBMers invited on a tour of the Steward Observatory Mirror Lab [SOML].
SOML was built in 1990 underneath the football stadium at the University of Arizona. Why under the stadium? Their motivation was [Chicago Pile-1], the world's first nuclear reactor, built by Enrico Fermi under the football stadium at the University of Chicago.
At other mirror labs, mirrors start as a large, heavy, flat piece of glass and then ground and polished to the correct parabolic curve. SOML created a new process that works a lot better, similar to making a [Pineapple Upside Down Cake]. For those who are not familiar with this cake, you arrange sliced pineapple rings on the bottom of the baking dish, then pour the liquid cake batter that fills in and around the pineapple slices, then bake.
The first step is creating a base of 1,690 hexoganal tubes made of Aluminum Silicate. These are like the pineapple rings in the cake. The tubes are bolted to the baking dish that is 8.4 meters wide. These tubes form the base of the [parabolic shape] that focuses starlight to a small focal point. The tubes are spaced with about an inch of space in between. The Aluminum silicate feels like clay.
Once the base is built, chunks of glass are placed on the surface. Rather then pouring on the cake mix of molten glass, these chunks will be melted in place. This isn't normal glass, but a special Boron Silicate glass that does not expand or contract much during changes in temperature, made by the [Ohara Corporation] in Japan.
The oven is then lowered onto the baking dish. Once the temperature reaches 700 degrees, the entire system is then rotated at 7 RPM. This allows the glass to melt and take its parabolic shape through [centrifugal force]. The people who run the oven are called "oven pilots", and they monitor the entire process to make sure nothing goes wrong.
This particular mirror is one of the two that will go into the [Large Binocular Telescope]. The mirror will be 36 inches thick at the edges, and 18 inches in the middle. If the glass cools down to quickly, it may crack or form crystals, so instead the oven is kept in place and the temperature lowered slowly over the course of a few months. This is called annealing.
Once a mirror has annealed, 24 suction cups are glued to the top surface to pull the mirror out of the baking dish. It is then tipped on its side so that all the bolts can be removed and the hexagonal tubes washed out, leaving behind a honey-combed effect on the bottom of the mirror. This means the mirror is 80 percent air, making it strong and lightweight.
The next step is grinding the surface with diamonds. In most cases, the process of spinning creates the correct shape so little grinding is required. However, for this mirror here for the Large Synoptic Survey Telescope [LSST], about five tons of glass will be ground out of the center. This will actually have two parabolic curves, the outer curve is shallow, and the inner curve is deep. This will allow for the LSST to survey a wide area of space at a time.
Once the glass is ground to the right shape, it will be polished with Cerium Oxide, what is commonly known as Jeweler's Rouge. How smooth does it have to be? If this mirror were the size of the United States, there would be no bump higher than 2 inches tall!
Most mirrors are symmetrical, so the polishing can be done on a spinning platform, but this mirror is not. The Large Magellan Telescope will consist of seven mirrors, one in the middle that is symmetrical, and surrounded by six other mirrors that will all continue the parabolic shape in each direction. This is one of the outer mirrors, which means that each part of the polishing process will be controlled by computers to get exactly the curve required.
Here is a small scaled-down model of the Magellan Telescope. Each of the seven mirrors will be 8.4 meters wide. At this point, one person asked why all the mirrors were 8.4 meters wide. I joked that this was the size of the oven! It reminded me of [the story where newly-wed had to ask her grandmother why she cut the ends off the pot roast]. The actual reason was that the posts of the football stadium are 8.5 meters wide, so any mirror made inside the lab larger than that could not be removed easily for transportation.
The LMT will be installed on [Cerro Tololo] in Chile, where my father worked earlier in his career. Why Chile? Observatories need high altitude, dry climate and clear skies. That is why Arizona is home to many observatories, including Kitt Peak National Observatory and the Vatican Observatory on Mount Graham. Cerro Tololo in Chile is close to the equator and meets these requirements.
Once operational in 2020, it will gather 6 TB of images every evening. That got all of the IBMers on the tour very excited!
To verify the polishing is complete, it is put on three red stands and measured with a laser. Once the measurements are complete. The surface will be coated with aluminum to provide the reflective surface. You can't just paint the surface with a roller! Instead, the aluminum is vaporized and allowed to land on the surface of the mirror evenly, in a layer that is only three molecules thick. There is more aluminum in standard size beer can than on the surface of one of these 8.4 meter size mirrors!
So that was the tour. It took almost 2 hours. If you are ever in Tucson, consider contacting the SOML and arranging a tour for yourself. There is no other mirror lab like it!
The old adage applies "You can't please everyone. Presidents can't. Prostitutes can't. Nobody can." I am reminded of that as I fielded a variety of interesting comments and emails about, of all things, my choice of order of things in recent blog posts.
Certainly, there are times when the order of things matters greatly. In my now-infamous blog post [Sock Sock Shoe Shoe], I use a scene from a popular 1970's television show to explain why compression should be done before encryption.
In my case, I put things in the order that I felt made sense to me, but not everyone agrees. Here are three recent examples:
In my blog post [Two IBMers Earn Their Retirement], I congratulated two of my colleagues on their retirement. Since their retirement happened on the same day, I decided to mention Mark Doumas first, and Jim Rymarczyk second.
However, one of my readers, who I will assume is a member of the unofficial "Jim Rymarczyk fan club", felt that I should have listed Jim first, as Jim served IBM for 44 years, and Mark only 32 years.
Really? I realize that movie stars insist on having their name listed first on the poster, but neither of these guys would be confused with George Clooney!
So, to Jim and all his fans out there, I assure you I did not mean this as a slight in any way. I have updated the post to indicate that the ordering was strictly alphabetical by last name.
In my blog post [IBM Announcements for February 2012], I presented tape products first, and disk second. Normally, I cover them alphabetically, disk first, then tape. However, I was asked to promote tape this year in preparation for the upcoming 60th anniversary of tape, so I mentioned the tape announcements first, and the disk second.
The feedback from the XIV community was swift. Many felt that I [buried the lede] in not mentioning the XIV Gen3 SSD caching first.
(Note: For those not familiar with the phrase used in journalism, 'burying the lede' refers to the failure to mention the most interesting or attention grabbing elements of a story in the first paragraph. In American news journalism, it is spelled "lede" and elsewhere it is spelled "lead". Major US dictionaries apparently accept both spellings for this phrase.)
Technically, my lead paragraph stated clearly that: "This week we have announcements for both disk and tape, but since 2012 is the 60th Diamond Anniversary for tape, I will start with tape systems first."
So, while I don't claim to be a journalist by any means, I think the lead paragraph accurately reflected that I would talk about both disk and tape products in the rest of the blog post, and if a reader didn't care to learn more about tape could bypass those sections and go directly to the section on disk instead.
I have had my head handed to me on a platter so many times here at IBM that I am considering installing a zipper around my neck. My friends in XIV land insisted that I write a secondary post about XIV Gen3 SSD caching that had no mention of tape whatsoever. One suggestion was to compare and contrast XIV Gen3 SSD caching with EMC's announcement for VFCache. The result was my blog post [IBM XIV Gen3 SSD Caching versus EMC VFCache].
What could go wrong with an apples-to-orange comparison of two different storage products sprinkled with a small amount of FUD against a major competitor?
I had two complaints on this one. First, is the order of products in my side-by-side table of comparisons. I put EMC VFCache in the left column, and IBM XIV Gen3 SSD caching in the right. I meant nothing sinister by this. Alphabetically, EMC comes before IBM, and VFCache comes before XIV. Chronologically, EMC's announcement came out on Monday, and IBM's announcement came out the following day.
(Note: The term [sinster] comes from the Latin word sinistra meaning "left hand". In the Middle Ages it was believed that when a person was writing with their left hand they were possessed by the Devil. Left-handed people were therefore considered to be evil. My poor mother was born left-handed and was forced as a child to write with her right hand to be accepted by society.)
Apparently, an unwritten convention within IBM is that comparison tables always have the newer product on the left column, followed by one or more older products to the right, or the IBM product on the left column, with one or more competitive alternatives to the right.
The second complaint came from a reader in the comments section: "... I think [what] you're doing is trying to ride EMC's release for your own marketing, did you really need to? XIV is an excellent array; adding SSD Cache to the Gen3 takes it further, Moshe would be fuming (which I think is a good thing), can you just stick to that and not ride someone else's wave?"
Both announcements relate to reducing latency of read IOPS through the use of Solid State Drives. That both companies would announce these were no surprise to any employee at either company, as both IBM and EMC have been talking about their intent to do so last year. IBM's announcement of XIV SSD Gen3 caching was certainly not in response to EMC's VFCache announcement, and I doubt EMC rushed out their VFCache announcement the day before as a pre-emptive strike against IBM's announcement of the XIV Gen3 SSD Caching feature.
(Note: I don't know her personally, but she has thousands of followers!)
There you have it. I will gladly fix false or misleading information, but I am not going to re-arrange the order of things just to please some readers, only to have other readers complain that they liked it better in the original order. As always, feel free to comment on any of this in the section below.
I can't believe we got snow this week on Valentine's Day! It didn't last long on the ground here in Tucson, but there are still some white caps in our mountains. For those of you "trapped" by snow, or too much work, here are two upcoming events you can attend from your desk and computer!
IBM Oracle Virtual University 2012
Please join us for the fourth annual IBM Oracle Virtual University that runs "live" for 24 hours, then continues 'on-demand' replay through the remainder of 2012.
From: Tuesday, February 21, 6:00 am US Eastern Time EST (6:00 pm China Time)
To: Wednesday, February 22, 6:00 am EST
This is a great educational event for IBM and Business Partner sales & technical teams who sell IBM Oracle solutions or have Oracle solutions installed in their account. It is for anyone who is new to or interested in the IBM Oracle Alliance as well as experienced sales & technical people who need all the latest on the IBM/Oracle co-opetition relationship for 2012 and beyond.
This VIRTUAL on-line event will cover key topics around the IBM Oracle Alliance. I am one of the speakers and will cover IBM System Storage offerings as they relate to Oracle software.
This is a chance for sellers to hear an update on what's new, unique and available to sell in 2012. The goal of this session is to help enable you to sell more IBM products and services with Oracle solutions in 2012! Learn where to go for help to better understand these solutions, close more deals and reach your targets.
Even through economic challenges, storage requirements have continued to grow along with the information explosion.
Join us for this informative webcast and hear from Jon Toigo, CEO and Managing Principal of Toigo Partners, as he discusses six cutting-edge storage technologies that are ready for prime time and can help transform your data center.
Date: Tuesday, February 28
Time: 1:00 pm EST, 12"00 pm CST, 10:00 am PST
The featured speaker is fellow blogger Jon Toigo, CEO and Managing Principal, Toigo Partners, an outspoken technology consumer advocate and vendor watchdog whose articles, columns, and blog posts on [DrunkenData.com] are enjoyed by over a million readers per month.
Raj hails from Toronto, Canada and will be able to provide the Canadian perspective on all things Storage. I had the pleasure to meet Raj in person here in Tucson when him and dozens of his cohorts came down for a multi-customer briefing at the [IBM Executive Briefing Center] where I work.
It takes me 20-30 minutes to complete a crossword or Sudoku puzzle. I am in no hurry, and I find the process relaxing. But what if you were paid to complete a puzzle? In that case, finishing the puzzle sooner, in fewer minutes, means more money in your paycheck per hour worked! However, getting paid would mean that doing these puzzles may no longer be fun or relaxing.
The idea of converting a hobby into a revenue-generating activity is not new. Who wouldn't want to earn money doing something you were planning to do already? The television is full of commercial advertisements for credit cards where you can earn Double Miles or Cash Rewards just for spending money on things you were going to spend on anyways.
But is "earn" the right word? The merchants pay a percentage fee every time a patron uses a credit card, and the bank is just providing a marketing incentive in the form of a portion of those fees back to the consumer, to encourage more usage of their card versus other forms of payment. Sort of like "profit sharing".
(FTC Disclosure: I am a full-time employee and shareholder of the IBM Corporation. This blog post should not be considered an endorsement for anything. My opinions and writings are based on publicly available information and my own experiences doing freelance work prior to my employment at IBM. I have no hands-on experience with Amazon Mechanical Turk, neither as a worker nor requester, have not participated in TopCoder contests, nor have I used the Viggle app. I do not have any financial interest in Amazon, TopCoder, Viggle or any other third-party company mentioned on this blog post, nor has anyone paid me to mention their company names, brands or offerings.)
Here's how it works. You get the app on your phone, and register each television show as you watch it. You can watch the show live, or much later recorded on your Tivo. You watch the shows you were going to watch anyways, and just provide your demographics, all in the name of market research. You get two points per minute of watching, and after 7,500 points, you get a $5 gift card from retailers such as from retailers such as Burger King, Starbucks, Best Buy, Sephora, Fandango, and CVS drugstores. For the typical American, it would take about three weeks to watch that much television!
Of course, this is not the only way to earn money working from home. A reader asked me for my opinions of [Amazon Mechanical Turk]. While the other examples above are done for marketing purposes, Mechanical Turk can be used for a variety of other things. Up to now, the IT industry has regarded the Cloud as the delivery of computing as a service, with the infrastructure, hardware and software existing on internationally networked servers, effectively invisible to the end user. This model is now to being applied broadly to people.
Basically, Mechanical Turk acts as a marketplace, where employers post Human Intelligent Tasks (HITs) that workers can do. Most can be completed in minutes and you are paid pennies to do so. Some examples might help illustrate what a HIT looks like:
Call a business and get the email address of the manager in charge.
Review a photograph and describe its style or content in three words or less
Select among multiple choices to categorize a job listing or company position
As a Mechanical Turk worker, you only work on the HITs you choose to work on, presumably those that interest you, and that you can do well and quickly. Workers can do this anytime, anywhere, such as 2:00am in the morning, at home, when you can't sleep or taking care of children. You can choose to work as much or as little as you like.
The employers--referred to as Mechanical Turk requesters--put money into their payroll accounts, load up their tasks, and hit publish. This gives them immediate access to a global, on-demand 24-by-7 workforce that can help complete thousands of HITs in minutes. These employers won't have to put an advertisement in the want ads and interview potential candidates, just to let them go later when the project is over.
Just like any other job, Mechanical Turk wages are reported to the IRS, and each person's work is evaluated for quality. In doing these tasks, you build up your "digital reputation" that will either prevent you or allow you to work on certain HITs. You can also take tests to reach Qualification levels to be eligible to work on HITs not available to everyone else.
Software engineers would have a hard time writing an Artificial Intelligence [AI] program to do these simple tasks, so being able to generate a HIT for something in the middle of a computer program might be the easiest way to get past a difficult part of an algorithm. Amusingly, Amazon describes this form of [crowdsourcing] as an artificial form of Artificial Intelligence!
While this approach may work for small, easily defined tasks, what about works that require a high amount of Human Intelligence, like storage software or hardware development?
When I was working for IBM as a software engineer in the 1980s and 1990s, it took us years to get a project done, using the traditional [Waterfall Model]. My job as a software architect was to estimate the thousands of lines of code (KLOC) a project would require, estimate the number of Person-Years (PY) it would take, and recommend the appropriate sized team. Back then, each engineer averaged only about 1,000 lines of software code per year, so KLOC and PY were often used interchangeably. Fellow IBM author Fred Brooks wrote an excellent book on the process called [The Mythical Man-Month].
The Waterfall model has the advantage that people only have to work a portion of the cycle on the project. In between, there was plenty of downtime to attend training, improve your skills, or take vacation. As our director Lynn Yates would often complain, "if they are only writing two lines of code in the morning, and two in the afternoon, why do they need time to rest?"
The Waterfall model was not perfect, and had its share of critics. One downside was that the clients didn't see anything until General Availability (GA), with a few getting a glimpse a few months earlier during our Early Support Program (ESP). By the time clients could tell us it was not what they wanted or expected, it was too late to change until the next release.
To address this concern, 17 software engineers wrote the now famous [Agile Manifesto]. The authors felt that collaboration, between the developers and with the clients, is critical to success. Business people and developers must work together daily throughout the project. The most efficient and effective method of conveying information to and within a development team is face-to-face conversation. The best architectures, requirements, and designs emerge from self-organizing teams. The result is an iterative approach that allows the client to see working prototypes early in the process, allowing last-minute changes to requirements to influence the final product.
Combining the Mechanical Turk concept with Agile programming methodology gives you what IBM calls an "Outcomes Model" approach. In the IBM research paper [Software Economies] (PDF, 5 pages), the authors argue that there are four fundamental principles needed for an "Outcomes Model" approach:
Autonomy. All of the actions necessary to bring jobs to completion should be driven by market forces; the process is
never gated by an entity outside of the market.
Inclusiveness. Everyone who provides information or performs work that leads to improvements should share in the
Transparency. The system should be transparent with respect to both the flow of money in the market and the tasks
performed by workers in the market.
Reliability. The system should be immune to manipulation, robust against attack (e.g., via insertion of untrusted code),
and prevent "shallow" work which would have to be re-done later.
I was surprised to see that [the TopCoder Community is 390,593 strong], nearly the size of the entire IBM company. TopCoder is focused on computer programming and digital creation using the Outcomes Model approach. Rather than paying everyone for their work, however, the platform is designed around challenges and competitions, and the top players or contributors are rewarded with cash prizes.
As an innovative company, IBM constantly explores a variety of means and approaches to offer value to its clients and customers. These new approaches may have some distinct advantages not just for IBM and its shareholders, but also for its clients and the freelancers hired to work on these projects. The global marketplace is getting flatter, smaller and smarter. It will be interesting how this plays out. If the discussion above encourages you to hone your technical skills, perhaps that is motivation enough to get off the couch and stop watching so much television!
Have you ever noticed that sometimes two movies come out that seem eerily similar to each other, released by different studios within months or weeks of each other? My sister used to review film scripts for a living, she would read ten of them and have to pick her top three favorites, and tells me that scripts for nearly identical concepts came all the time. Here are a few of my favorite examples:
1994: [Wyatt Earp] and [Tombstone] were Westerns recounting the famed gunfight at the O.K. Corral. Tombstone, Arizona is near Tucson, and the gunfight is recreated fairly often for tourists.
1998: [Armageddon] and [Deep Impact] were a pair of disaster movies dealing with a large rock heading to destroy all life on earth. I was in Mazatlan, Mexico to see the latter, dubbed in Spanish as "Impacto Profundo".
1998: [A Bug's Life] and [Antz] were computer-animated tales of the struggle of one individual ant in an ant colony.
2000: [Mission to Mars] and [Red Planet] were sci-fi pics exploring what a manned mission to our neighboring planet might entail.
This is different than copy-cat movies that are re-made or re-imagined many years later based on the previous successes of an original. Ever since my blog post [VPLEX: EMC's Latest Wheel is Round] in 2010 comparing EMC's copy-cat product that came our seven years after IBM's SAN Volume Controller (SVC), I've noticed EMC doesn't talk about VPLEX that much anymore.
This week, IBM announced [XIV Gen3 Solid-State Drive support] and our friends over at EMC announced [VFCache SSD-based PCIe cards]. Neither of these should be a surprise to anyone who follows the IT industry, as IBM had announced its XIV Gen3 as "SSD-Ready" last year specifically for this purpose, and EMC has been touting its "Project Lightning" since last May.
Fellow blogger Chuck Hollis from EMC has a blog post [VFCache means Very Fast Cache indeed] that provides additional detail. Chuck claims the VFCache is faster than popular [Fusion-IO PCIe cards] available for IBM servers. I haven't seen the performance spec sheets, but typically SSD is four to five times slower than the DRAM cache used in the XIV Gen3. The VFCache's SSD is probably similar in performance to the SSD supported in the IBM XIV Gen3, DS8000, DS5000, SVC, N series, and Storwize V7000 disk systems.
Nonetheless, I've been asked my opinions on the comparison between these two announcements, as they both deal with improving application performance through the use of Solid-State Drives as an added layer of read cache.
(FTC Disclosure: I am both a full-time employee and stockholder of the IBM Corporation. The U.S. Federal Trade Commission may consider this blog post as a paid celebrity endorsement of IBM servers and storage systems. This blog post is based on my interpretation and opinions of publicly-available information, as I have no hands-on access to any of these third-party PCIe cards. I have no financial interest in EMC, Fusion-IO, Texas Memory Systems, or any other third party vendor of PCIe cards designed to fit inside IBM servers, and I have not been paid by anyone to mention their name, brands or products on this blog post.)
The solutions are different in that IBM XIV Gen3 the SSD is "storage-side" in the external storage device, and EMC VFCache is "server-side" as a PCI Express [PCIe] card. Aside from that, both implement SSD as an additional read cache layer in front of spinning disk to boost performance. Neither is an industry first, as IBM has offered server-side SSD since 2007, and IBM and EMC have offered storage-side SSD in many of their other external storage devices. The use of SSD as read cache has already been available in IBM N series using [Performance Accelerator Module (PAM)] cards.
IBM has offered cooperative caching synergy between its servers and its storage arrays for some time now. The predecessor to today's POWER7-based were the iSeries i5 servers that used PCI-X IOP cards with cache to connect i5/OS applications to IBM's external disk and tape systems. To compete in this space, EMC created their own PCI-X cards to attach their own disk systems. In 2006, IBM did the right thing for our clients and fostered competition by entering in a [Landmark agreement] with EMC to [license the i5 interfaces]. Today, VIOS on IBM POWER systems allows a much broader choice of disk options for IBM i clients, including the IBM SVC, Storwize V7000 and XIV storage systems.
Can a little SSD really help performance? Yes! An IBM client running a [DB2 Universal Database] cluster across eight System x servers was able to replace an 800-drive EMC Symmetrix by putting eight SSD Fusion-IO cards in each server, for a total of 64 Solid-State drives, saving money and improving performance. DB2 has the Data Partitioning Feature that has multi-system DB2 configurations using a Grid-like architecture similar to how XIV is designed. Most IBM System x and BladeCenter servers support internal SSD storage options, and many offer PCIe slots for third-party SSD cards. Sadly, you can't do this with a VFCache card, since you can have only one VFCache card in each server, the data is unprotected, and only for ephemeral data like transaction logs or other temporary data. With multiple Fusion-IO cards in an IBM server, you can configure a RAID rank across the SSD, and use it for persistent storage like DB2 databases.
Here then is my side-by-side comparison:
IBM XIV Gen3 SSD Caching
Selected x86-based models of Cisco UCS, Dell PowerEdge, HP ProLiant DL, and IBM xSeries and System x servers
All of these, plus any other blade or rack-optimized server currently supported by XIV Gen3, including Oracle SPARC, HP Titanium, IBM POWER systems, and even IBM System z mainframes running Linux
Operating System support
Linux RHEL 5.6 and 5.7, VMware vSphere 4.1 and 5.0, and Windows 2008 x64 and R2.
All of these, plus all the other operating systems supported by XIV Gen3, including AIX, IBM i, Solaris, HP-UX, and Mac OS X
FCP and iSCSI
Vendor-supplied driver required on the server
Yes, the VFCache driver must be installed to use this feature.
No, IBM XIV Gen3 uses native OS-based multi-pathing drivers.
External disk storage systems required
None, it appears the VFCache has no direct interaction with the back-end disk array, so in theory the benefits are the same whether you use this VFCache card in front of EMC storage or IBM storage
XIV Gen3 is required, as the SSD slots are not available on older models of IBM XIV.
Shared disk support
No, VFCache has to be disabled and removed for vMotion to take place.
Yes! XIV Gen3 SSD caching shared disk supports VMware vMotion and Live Partition Mobility.
Support for multiple servers
An advantage of the XIV Gen3 SSD caching approach is that the cache can be dynamically allocated to the busiest data from any server or servers.
Support for active/active server clusters
Aware of changes made to back-end disk
No, it appears the VFCache has no direct interaction with the back-end disk array, so any changes to the data on the box itself are not communicated back to the VFCache card itself to invalidate the cache contents.
None identified. However, VFCache only caches blocks 64KB or smaller, so any sequential processing with larger blocks will bypass the VFCache.
Yes! XIV algorithms detect sequential access and avoid polluting the SSD with these blocks of data.
Number of SSD supported
One, which seems odd as IBM supports multiple Fusion-IO cards for its servers. However, this is not really a single point of failure (SPOF) as an application experiencing a VFCache failure merely drops down to external disk array speed, no data is lost since it is only read cache.
6 to 15 (one per XIV module) for high availability.
Pin data in SSD cache
Yes, using split-card mode, you can designate a portion of the 300GB to serve as Direct-attached storage (DAS). All data written to the DAS portion will be kept in SSD. However, since only one card is supported per server and the data is unprotected, this should only be used for ephemeral data like logs and temp files.
No, there is no option to designate an XIV Gen3 volume to be SSD-only. Consider using Fusion-IO PCIe card as a DAS alternative, or another IBM storage system for that requirement.
Pre-sales Estimating tools
Yes! CDF and Disk Magic tools are available to help cost-justify the purchase of SSD based on workload performance analysis.
IBM has the advantage that it designs and manufactures both servers and storage, and can design optimal solutions for our clients in that regard.
Well, it's Tuesday again, and you know what that means! IBM Announcements! Typically, IBM System Storage has three to five major product launches per year. Making announcements every Tuesday would have been two frequent, and having one big announcement every two or three years would be too far apart. Worldwide combined revenues for storage hardware and software grew double digits last year, comparing full-year 2011 to the prior 2010 year, and I am sure that 2012 will also be a good year for IBM as well! This week we have announcements for both disk and tape, but since 2012 is the 60th Diamond Anniversary for tape, I will start with tape systems first.
TS1140 support for JA/JJ tape cartridges
The TS1140 enterprise tape drive was announced at the [Storage Innovation Executive Summit] last May. It supported a new E07 format on three different new tape cartridges. Models "JC" was 4.0TB standard re-writeable tapes, "JY" was 4.0TB WORM tapes, and "JK" were 500GB economy tapes that were less expensive, but offered faster random access.
Generally, IBM has adopted an N-2 read, N-1 write [backward compatibility]. This means that the TS1140 could read E05 and E06 formatted tapes on JB and JX media, and could write E06 format on JB and JX media. However, there are a lot of older JA and JJ media, especially as part of TS7740 environments, so IBM now supports TS1140 drives to read J1A formatted JA and JJ media. This is not just for TS7740 environments, any TS1140 in stand-alone or tape library configurations will support this as well.
TS7700 R2.1 enhancements
IBM is a leader in tape virtualization with or without physical tape as back-end media. There are two hardware models of the [IBM Virtualization Engine TS7700 family] for the IBM System z mainframe. These virtual libraries are referred to as "clusters" in IBM literature.
The TS7740 Virtual Tape Library supports putting virtual tape images on disk first, then move less-active data to physical tape, which I covered in my blog post [IBM Announcements - July 2007].
A unique feature of the TS7700 series is support for a Grid configuration, which allows up to six different TS7700 clusters to be grouped into a single instance image. These clusters can be in local or remote locations, connected via WAN or LAN connections.
R2.1 is the latest software release of this successful IBM's TS7700 series.
True Sync Mode Copy. Before R2.1, the TS7700 offered "immediate mode copy". An application would write to a virtual tape, and when it was done with the tape and performed an unmount, the TS7700 would then replicate the tape contents to a secondary cluster on the grid. With True Sync Mode, data contents are replicated per implicit or explicit SYNC points. This is another IBM first in the IT tape industry.
Remote Mount Fail-over. When you have two or more TS7700 clusters in a grid configuration, you can do remote mounts. We've added fail-over multi-pathing up to four paths, so that if a link to a remote cluster is down, it will try one of the others instead.
Parallel Copies and Pre-Migration. On of my 19 patents is for the pre-migration feature for the IBM 3494 Virtual Tape Server (VTS) that carries forward into the TS7700, and is also used in the SONAS and Information Archive products. However, when the grid architecture was introduced, the engineers decided not to allow pre-migration and copies to secondary clusters to occur concurrently. Now these two operations can be done in parallel.
Merge two grids into one grid. Now that we can support up to six clusters into a single grid, we have people with 2-cluster and 3-cluster grids looking to merge them into one. Of course, all the logical and physical volume serials (VOLSER) must be unique!
Accelerate off JA/JJ Media. There are a lot of older JA and JJ media still in TS7700 libraries. This feature allows customers to speed up the transition to newer physical tape media.
Copy Export to E06 format on JB media. This one is clever, and I have to say I would have never thought about it. Let's say you have a TS7740 with TS1140 drives, but you want to export some virtual tapes to physical media to be sent to someone who only has a TS7740 connected with older TS1130 drives. These older drives can't read new JC media nor make sense of the E07 format. This feature will let you export to older JB media in E06 format so that it will be fully readable at the new location on the TS1130 drives.
Copy Export Merge service offering. Thanks to mergers and acquisitions, it is sometimes necessary to split off a portion of data from a TS7700 grid. In the past, IBM supported sending this export to a completely empty TS7700 library, but this new service offerings allows the export to be merged into an existing TS7700 that already contains data.
LTFS-SDE support for Mac OS X 10.7 Lion
How do people still not yet know about the Linear Tape File System [LTFS]? I mentioned this in my blogs back in 2010 in [April], [September], and [November]. Last year, LTFS was the [NAB Show Pick Hits Award] and an [Emmy] for revolutionizing the use of digital tape in Television broadcasting.
In layman's terms, the Single Drive Edition [LTFS-SDE] allows a tape cartridge to be treated like USB memory stick. It is supported on the LTO5 tape drives for systems running various levels of Windows, Linux and Mac OS X. Prior to this announcement, IBM supported Snow Leopard (10.5.6) and Leopard (10.6), and now supports Mac OS X 10.7 "Lion" release.
IBM first introduced Solid-State Drives (SSD) back in 2007 where it made sense the most, in [drive-for-drive replacements on blade servers in the IBM BladeCenter]. Blade servers typically only have a single drive, and SSD are both faster and use less energy on a drive-for-drive comparison, so this provided immediate benefit. Today, SSD are available on a variety of System x and POWER system servers.
In 2008, IBM rocked the world by being the first to reach [1 Million IOPS with Project Quicksilver]. This was an all-SSD configuration which many considered unrealistic (at the time), but it showed the potential for solid state drives.
When the [XIV Gen3 was Announced - July 2011], each module included an 1.8-inch "SSD-Ready" slot in the back. IBM made a Statement of Direction that IBM would someday offer SSD drives to put in these slots. Today's announcement is that IBM has finalized the qualification process, so now XIV Gen3 clients can have 400GB of usable non-volatile SSD read cache added to each module. This SSD can be added to existing XIV Gen3 boxes in the field, or it can be factory-installed in new shipments. If you have a 15-module XIV, that's 6TB of additional read cache! This SSD is entirely managed by the XIV Gen3, so you won't have to spend weeks reading manuals or specifying configuration parameters.
When you carve volumes on the XIV, you now have an option to enable or disable use of the SSD cache for each volume. Since XIV is being used in private and public cloud deployments, this offers the ability to offer premium performance at premium prices. The use of SSD is complementary to IBM XIV Quality of Service (QoS) performance levels, which are determined by host instead.
Well, that's the first major IBM System Storage launch of 2012. Let me know what you think in the comment section below.
Last week, on January 31, two of my colleagues retired from IBM. At IBM, retirements always happen on the last day of the month. Here is my memories of each, listed alphabetically by last name.
Mark Doumas retires after working 32 years with IBM. Mark was my manager for a few months in 2003. Back then, IBM was working on launching a variety of new products, including the IBM SAN File System (SFS), the IBM SAN Volume Controller (SVC), a new release of Tivoli Storage Manager (TSM), and TotalStorage Productivity Center (TPC), which was later renamed to IBM Tivoli Storage Productivity Center.
Mark was manager of the portfolio management team, and I was asked to manage the tape systems portfolio. I am no stranger to tape, as one of my 19 patents is for the pre-migration feature of the IBM 3494 Virtual Tape Server (VTS). The portfolio included LTO and Enterprise tape drives, tape libraries and virtual tape systems. My job was to help decide how much of IBM's money we should invest in each product area. This was less of a technical role, and more of a business-oriented project management position
Portfolio management is actually part of a chain of project management roles. At the lowest level are team leads that manage individual features, referred to as line items of a release. Release managers are responsible for all the line items of a particular release. Product managers determine which line items will be shipped in which release, and often have to balance across three or more releases. Architects help determine which products in a portfolio should have certain features. Since I was chief architect for DFSMS and Productivity Center, stepping up to portfolio manager was naturally the next rung on the career ladder.
(Side note: If you were wondering why I was only a few months on the job, it was because I was offered an even better position as Technical Evangelist for SVC. See my 2007 blog post [The Art of Evangelism] for a humourous glimpse of the kind of trouble I got in with that title on my business card!)
While my stint in this role was brief, I am still considered an honorary member of the tape development team. Nearly every week I present an overview of our tape systems portfolio at the Tucson Executive Briefing Center, or on the road at conferences and marketing events.
This year, 2012, marks the 60th anniversary of IBM Tape, but I will save that for a future post!
Jim is an IBM Fellow for IBM Systems and Technology Group. There are only 73 IBM Fellows currently working for IBM, and this is the highest honor IBM can bestow on an employee. He has been working with IBM since 1968 and now retires after 44 years! Jim was tasked with predicting the future of IT, and help drive strategic direction for IBM. Cost pressures, requirements for growth, accelerating innovation and changing business needs help influence this direction.
Many consider Jim one of the fathers of server virtualization. For those who think VMware invented the concept of running multiple operating systems on a single host machine, guess again! IBM developed the first server hypervisor in 1967, and introduced the industry's first [offical VM product on August 2, 1972] for the mainframe.
When I joined IBM in 1986, my first job was to work on what was then called DFHSM software for the MVS operating system. Each software engineer had unlimited access to his or her own VM instance of a mainframe for development and testing. This was way better than what we had in college, having to share time on systems for only a few minutes or hours per day. Today, DFHSM is now called the DFSMShsm component of DFSMS, an element of the z/OS operating system.
At various conferences like [SHARE] and [WAVV] we celebrated VM's 25th anniversary in 1997, and its 30th anniversary in 2002. Today, it is called z/VM and IBM continues to invest in its future. Last October, IBM announced [z/VM 6.2] release which provides Live Guest Relocation (LGR) to seemlessly move VM guest images from one mainframe to another, similar to PowerVM's Live Partition Mobility or VMware's VMotion.
Lately, it seems employees at other companies jump from job to job, and from employer to employer, on average every 4.1 years. According to [National Longitudinal Surveys] conducted by the [US. Government's Bureau of Labor Statistics], the average baby boomer holds 11 jobs. In contrast, it is quite common to see IBMers work the majority of their career at IBM.
The next time you have a tasty beverage in your hand, raise your glass! To Mark and Jim, you have earned our respect, and you both have certainly earned your retirement!
Mark your calendars! If you work in IT and have an interest in storage, then there are two upcoming conferences you might be interested in attending!
Join a network of your peers at
[IBM Pulse2012] who are fundamentally and cost-effectively changing the economics of IT and speeding the delivery of innovative products and services. With four days of top-notch education, Pulse 2012 will help you react with agility in changing competitive landscapes, reduce vulnerability throughout the service lifecycle, and continuously improve the business impact of the technology.
I presented at the very first IBM Pulse back in May 2008, which was a combination event to cover Tivoli Storage, Maximo and Netcool. For a bit of nostalgia, read my 2008 blog posts:
The IBM Pulse conference has certainly evolved over the past few years! The agenda is not yet finalized, so I don't know if I will be there again this year.
The second event has a new name. [IBM Edge2012] is the premier storage event that brings together innovative IBM technologies, world class training, leading industry experts, and compelling client success stories and best practices. Edge2012 is dedicated to helping you design, build and implement efficient storage infrastructure solutions.
We started doing these back in the mid-90s, entitled the "IBM Storage Symposium", then later the "IBM System Storage and Storage Networking Symposium". In 2007, I was there in Las Vegas presenting on a variety of topics. See my blog post [Storage Symposium 2007 recap].
In 2008, we had a version of the Storage Symposium down in Cuernavaca, Mexico. Not only did I present, but it was also a "book signing" event for my first book [Inside System Storage: Volume I]. Here were my blog posts: [Introduction], and [Conclusion]. We also had an event in the United States, as well as Montpelier, France, but since I already went to the one in Mexico, I let my colleagues go to these other ones instead.
In 2009, IBM experimented with combining two conferences under one roof in Chicago, IL. The IBM System Storage and Storage Networking Conference was combined with the IBM System x and BladeCenter Technical Conference. The idea was that server people would probably also be interested in storage, and storage admins might also be interested in x86-based servers. See my blog post
[Storage Symposium 2009 recap].
In 2010, System Storage and System x were once again combined, held in Washington DC, but the conferences were renamed to IBM System Storage Technical University and the IBM System x Technical University to give them a common look and feel. See my blog post [Storage University 2010 review].
In 2011, not satisfied that two data points was inconclusive, IBM continued the experiment, hosting both System Storage and System x conferences in Orlando, Florida. Here were my blog posts:
