I am in Toronto, Canada. It is a lot cold and rainy here, worse than last week in Seoul, Korea.This looks like a slow news week, so slow that the only news here in Canada is the possibility of anew 5-dollar coin. I thought I would make this week's theme about enterprise applications.
IBM doesn't make these applications anymore, we have decided to focus on our core strength, to be the best IT platform to run other people's applications. This means being the best IT systems, software and services company. However, many of the companies that make enterprise applications are both cooperate and compete against parts of IBM, what we call "coopetition".
Let's take a look at some acronyms in this space:
"Enterprise Resource Planning" represents all the basic applications that business need to run theirbusiness, including: finance, accounting, human resources, and manufacturing. The focus here is to streamline operations and make the workforce more productive. Before IBM, I ran my ownsoftware development company, Pearson Kurath Systems, and we developed ERP applications for clients oneby one, customized to their industry requirements.
"Customer Relationship Management" or sometimes "Client Relationship Management" help companies identifyand retain their customer base. Focus here is to increase customer satisfaction and loyalty.
"Supply Chain Management" help track supply and just-in-time inventory demand, sharing the information withkey suppliers and distributors. The focus is to manage inventories down to nothing, and improve speed to get products out to market.
"Business to Business" refer to procurement, purchase orders, and collecting payments over the internet.One of my pet peeves are acronyms that use "2" to mean "to" and "4" to mean "for".
"Human Capital Management" deals with managing costs of Human Resources (HR) and coordinating servicesfrom outside organizations.
"Knowledge Management" refers to sharing and collaborating information. This is not just email and instant messaging, but also online calendaring, experience repositories, client case studies, and anecdotes.
This week I will cover applications that address these, and how they relate to storage.
Well, I have left Japan, and while everyone else is enjoying the Super Bowl, I am now in Australia, at another conference.Today I had the pleasure to hear filmmakers talk about their successes, and how IBM helps the movie industry.
At one extreme was Khoa Do, independent filmmaker. After acting in movies asideMichael Caine and Billy Zane, he decided to become his own director. He started a project to help seven disadvantaged youths from a poor drug-ridden section of Sydney, by having them act in his first full-length film.Armed with only an IBM laptop and small budget, he made the film called "The Finished People" that had critical acclaim.
The film was a success, and many of the disadvantaged youths have gone on to act in other movies. In 2005, Khoa Do was named "Young Australian of the Year".
Thanks to IBM technology, filmmaking is now accessible to a wider number of aspiring wanna-be directors. It is no longer necessary to be part of a large film studio with a multi-million dollar budget to tell your story.
At the other extreme, was Xavier Desdoigts, director of technical operations at Animal Logic, the Computer Graphics (CG) arthouse that produced special effects of movies like "The Matrix", "House of Flying Dragons" and "World Trade Center". They started with producing digital effects for TV commercials, like this one forCarlton Draught Beer.
With the support of a large film studio and multi-million dollar budget, Animal Logic now boasts the 86th most powerful "Supercomputer" based on IBM BladeCenter technology, with over 4000 servers connected into a cluster, for making the movie "Happy Feet". The movie took four years to make, with over 500 people, of 27 different nationalities. It was the first CG movie made in Australia, and has been well-received by audiences worldwide.
Mr. Desdoigts gave out some interesting facts and figures about the movie:
While visually stunning on the big screen, each frame is only 1.4 Megapixel, about the same resolution as most camera phones.
In one scene, there are 427,086 penguins all appearing on frame.
Mumble, the lovable lead character, is made up of over 6 million feathers.
As many as 17 dancers were "motion-captured" to choreograph the tap-dancing and character interaction segments.
Only one system admin was needed to manage this entire server farm. (IBM Systems Director technology makes this possible)
The movie consumed 103 TB of disk space, backed up to 595 LTO tape cartridges.
An estimated 17 million CPU-hours were needed for all the processing and rendering.
Rather than talking about technology for technology sake, these filmmakers showed how technology couldbe put to use, in a practical sense, to provide the world something of value.
Wrapping up this week's theme on Cloud Computing, I finish with an IBM announcement for two new products to help clients build private cloud environments from their existing Service Oriented Architecture (SOA) deployments.
IBM WebSphere CloudBurst Appliance -- a new hardware appliance that provides access to software virtual images and patterns that can be used as is or easily customized, and then securely deployed, managed and maintained in a private cloud.
IBM WebSphere Application Server Hypervisor Edition -- a version of IBM WebSphere Application Server software optimized to run in a virtualized hardware server environments such as VMware, and comes preloaded in WebSphere Cloudburst.
With more than 7,000 customer implementations worldwide, IBM is the SOA market leader. Of course, both of these products above can be used with IBM System Storage solutions, including Cloud-Optimized Storage offerings like Grid Medical Archive Solution (GMAS), Grid Access Manager software, Scale-Out File Services (SoFS), and the IBM XIV disk system.
IBM is part of the "Cloud Computing 5" major vendors pushing the envelope (the other four are Google, Microsoft, Amazon and Yahoo). In fact, IBM has a number of initiatives that allow customers to leverage IBM software in a cloud. IBM is working in collaboration with Amazon Web Services (AWS), a subsidiary of Amazon.com, Inc. to make IBM software available in the Amazon Elastic Compute Cloud (Amazon EC2). WebSphere sMash, Informix Dynamic Server, DB2, and WebSphere Portal with Lotus Web Content Management Standard Edition are available today through a "pay as you go" model for both development and production instances. In addition to those products, IBM is also announcing the availability of IBM Mashup Center and Lotus Forms Turbo for development and test use in Amazon EC2, and intends to add WebSphere Application Server and WebSphere eXtreme Scale to these offerings.

Besides, I have been in airplanes and airports nearly every week since March 1, so driving to Las Vegas was a pleasent alternative.
While driving to Las Vegas was pleasant, driving in Las Vegas was not. I would go crazy as a taxi driver here! I think I will leave my car in the free parking garage all week, and limit myself mostly to the Mandalay Hotel where the conference is being held, and only venture out to other hotels that are walking distance, like the Luxor next door.
In the evening, IBM hosted some of the industry's top analysts and press at an invitation-only reception. Several other IBMers were there, including Barry Whyte, Steve Kenniston, Nicki Rich and Ron Riffe. This event was organized by IBM Analyst Relations, including David Rasmussen and Leanna Holmquist.
Ron mentioned my penchant for taking pictures with other people and posting them on my blog, so I am glad that Leanna volunteered to take a picture with me for my first post of the week!
I would also like to mention that Ron Riffe has joined the ranks of storage bloggers. His blog is called [The Line]. Here is Ron's post on his "Day 0" observations here at Edge: [Rainy Days and Sunshine].
Continuing my week's theme on travel, conferences, and Japan, I provide three more"survival words" in Japanese language. These might seem like an odd trio, but they comein very handy.
Domo -- "very much"
This is short for "Domo Arigato" which is "Thank you very much". If you just say "Domo"they assume you mean the full phrase, and gets the same point across. Some of my older readersmay remember a song by Styx "Domo Arigato Mr. Roboto" which is perhaps the only song I could think ofthat mentions IBM and Japan in the same song.
You're wondering who I am-machine or mannequin With parts made in Japan, I am the modern man
I've got a secret I've been hiding under my skin My heart is human, my blood is boiling, my brain I.B.M.
Doko -- "where?"
This word is great for trying to find places or things, such as "Where is the restroom?"Sometimes making an attempt to speak a country's official language will garner some respectand appreciation from the locals. If you're lost, and looking for help finding something, this is a great time to be appreciated.
Upon arrival to Narita, I was planning to take the N'EX high-speed train into town, but there was a train accident on the JR line, so I ended up taking the Kisei train over to Nappori station,then transfer over to a different line. Not what I had planned, but an adventure nonetheless.
Dozo -- "after you" or "go ahead"
Japan is all about showing respect to your elders, upper management, and others in great esteem or authority. When arriving to a dinner table, or leaving the elevator, this phraselets them know you are respectful by letting them go first. Americans always seem rushed,so it is good to show I can be patient also.
For those who participated in Clark Hodge's "Where's Tony" contest,I was in Croatia, Bosnia and Herzogovina. There were optional side-tours to Montenegro and Slovenia, but I decided not to incur the added time and expense with those.
For those wondering where to go this Summer for vacation, I recommend Croatia. It is a beautiful country, with clean cities, good road conditions, and a calm Adriatic sea as we went from island to island.
And if you get to Mostar, don't let them talk you into jumping off the "old bridge". The water is terribly cold down there![Read More]
Last week, I opined that Monday's IDC announcement "IBM #1 in combined disk and tape storage hardwaresales for 2006" was in part because of a resurgence of interest in tape, with four specific examples. There was a lot of reaction and reflection fromboth sides.
On the one side...
EMC blogger Mark Twomey at Storagezilla admits that perhapsTape Isn't Dead after all,is perhaps the best place to put long-term archive data, but not for backup? EMC's "creative marketing types" put out this Fun With Tape video that I found amusing. (It asks for a first name,last name, and e-mail address, which are then embedded into the resulting video itself, and perhaps forwarded to your nearest EMC sales rep, so answer according to your wishes for privacy).
The "mummy wrapped in tape media" seems to be a common theme, and shows up again in LiveVault'svideo with John Cleese, which makes the same argument asthe EMC video above, namely: switch your backups from tape to disk because we are a disk-only vendor.
... and on the other side
JWT over at DrunkenData asks Which is greener, disk or tape?Tape is, of course, by a long shot, and an essential part of IBM's Big Green initiative, a project to invest$1US Billion dollars per year for data centers to be more efficient for power and cooling.
Sun/StorageTek blogger Randy Chalfant questions the Death of Tape, and argues thatdisk-only solutions suffer from atrophy.The results he posts from a survey of 200 customers are similar to those we've seen with customers using IBM TotalStorage Productivity Center, our software to help evaluate data usage, and identify misuse, in your data center.
To my readers in the USA, United Kingdom, Ireland, South Africa, China and Japan, and a few other countries, Happy Father's Day!
A Brief History of SVC and Storwize Family: What, How and Why?
Fellow IBM Master Inventor [and blogger] Barry Whyte gave an excellent session on the past 10 years of development history for IBM SAN Volume Controller and the rest of the Storwize Family based on its binary code. The SAN Volume Controller represents the start of a movement, what is now called "Software-Defined Storage", with a layer of abstraction that completely hides the differences between different back-end devices. The Storwize family is the most successful Software-defined Storage solution in the IT industry!
IBM Cloud Storage Architectures
IBM Clod Barrera presented an updated version of his "Cloud Storage Architecture" pitch from a technical and strategic viewpoint. From 2011 to 2015, external storage spend is increasing 25 percent for public cloud, and 17 percent for private cloud deployments, and that is not including all of the Do-it-yourselfers like Facebook who build their own storage devices from piece parts.
This year, Clod has expanded his "Cloud Storage Taxonomy" to six different categories:
OLTP/transactional, typically block-based
General purpose storage
Ephemeral storage that exists only while a specific virtual machine (VM) is running
Analytics, which tends to be more sequential than random in I/O pattern
IBM is a platinum sponsor of OpenStack, and is proud to have hundreds of contributors assigned to improve this open source initiative.
IBM Linear Tape File System - Enterprise Edition
IBM Ed Childers presented the latest announcement on Linear Tape File System [LTFS]. For a quick recap, IBM first introduced LTFS Standard Drive Edition [LTFS-SDE] in April 2010, which allowed workstations attached to single tape drives to use cartridges much like USB memory sticks. Then, IBM introduced LTFS Library Edition [LTFS-LE] which allows an entire tape library to be mounted as a file system, with each resident tape cartridge listed as a sub-directory.
Now, IBM has LTFS Enterprise Edition, which combines disk-based General Parallel File System [GPFS] with LTFS-LE, resulting in a combined hybrid disk-and-tape file system.
To provide a client's perspective, Konstantin Arnold with Biozentrum, the Life Sciences Research department of the University of Basel, Switzerland and SIB Swiss Institute of Bioinformatics presented some shocking information on their data growth. Biozentrum studies 3D protein folding, with information from the Worldwide Protein Data Bank [PDB] and [UniProt], which combines protein information from Swiss-Prot with manually annotations and TrEMBL computationally analyzed and automatically annotated entries.
Combining lab data, proteomics, deep-sequencing, imaging and high-content analysis, their storage requirements has grown exponentially, from less than 50 TB in 2009, to over 350TB in 2013. With the need to have such a large repository of unstructured data, it made sense to use LTFS-EE for this project!
IBMers presented the use of SAN Volume Controller (SVC) in a "stretch cluster" for a production environment at a bank in the Middle East. Before going into the technical details of the solution, they explained the challenges of running a bank under Sharia law. For example, Sharia law does not allow charging interest rates on borrowed money, but banks can charge fees for services. Debit cards are automatically denied at shops that are "black-listed" such as liquor stores, that are not consistent with the precepts of the Islamic religion.
The SVC implementation was rather straight-forward. IBM has offered Stretch Cluster since 2009 with version 5.1, but it only gained popularity years later when VMware pointed out that this can be used for datacenter to datacenter vMotion activity. The IBM team tested this out with a short 500 meter distance locally, before stretching it out to two locations now implemented. They have three SVC nodes managing 60TB of managed disk capacity at each data center, made up from a mix of DS8870, Storwize V7000 and DS3950 disk systems.
To demonstrate the robustness of the solution, the client requested that the IBM team demonstrate various recovery scenarios while running live in production mode! As you would expect, IBM SVC successfully handled every one.
IBM Cloud Storage with OpenStack and IBM System Storage
IBM Michael Factor presented this overview of OpenStack, and how IBM already supports various aspects of the open source initiative with products like SAN Volume Controller, XIV, and Storwize V7000.
This was the best overview of OpenStack I had heard. IBM is a platinum sponsor of this open source initiative, managed by the [OpenStack Foundation]. In traditional open source fashion, bi-annual releases are given alphabetically-ascending names. The last release was named Folsom, the current release is Grizzly, and the next release planned will be named Havana.
OpenStack is designed to manage your data center or cloud across four capabilities: Compute, Network, Storage and Shared Services. For Compute, the "Nova" project focuses on managing running VM instances, and "Glance" manages VM images that can be launched. The "Networking" project focuses on providing network connectivity. This was formerly called "Quantum", but Quantum (the company) felt there might be some confusion, so it was renamed to just "Networking".
For Storage, there are two projects, "Cinder" and "Swift". Cinder refers to persistent, external block storage, accessible via iSCSI or Fibre Channel. IBM's SAN Volume Controller, XIV and Storwize V7000 already support the Cinder API interface. Swift is focused on "object storage", which can provide an alternative way of storing information for cloud-based applications. SNIA's Cloud Data Management Interface (CDMI) is working with OpenStack to bring object storage into the mainstream.
With the Cinder API, applications can create volumes, take snapshots, set quotas, and attach these volumes to VM instances.
I realize there is a big time gap between this post and my last. Where have I been? "Where haven't I been?"... might be the better question! After my week at Edge, I flew from Las Vegas to Sao Paulo, Brazil where various protests delayed my departure, then visited clients in the Midwestern USA, then London to watch a bit of tennis. From there, I flew to Athens, Greece (and yes, more protests!), took some overdue time-off on the beach on various Greek islands, then taught a Storage Top Gun class in Bangalore, India. So, yes, I have been quite busy. I will try to catch up on typing up all my notes from the IBM Edge conference over the next few weeks!
Last week, Paul Weinberg of eChannelLine.com asks Is this the year of the SAN (again)?So, I thought this week I would cover my thoughts and opinions on storage networking. We oftenfocus on servers or storage devices, and forget that the network in between is an entire worldon itself.
I believe Mr. Weinberg is basing this on the idea that in 2007, over 50 percent of disk will beattached over SAN, edging out the alternative: Direct Attached Storage (DAS). But perhaps 50 percentis the wrong number to focus on. In 2007, The United Nations estimates thatcities will surpass rural areas, with just over 50 percent of theworld's population. Does that make this the "Year of the City"? Of course not.
Instead, I prefer to use the methodology that Malcolm Gladwell uses in his book, The Tipping Point.(I have read this book and highly recommend it!)Gladwell indicates that the tipping point happens at the start of the epidemic, not when it is half over.Isn't it better to celebrate the sweet 16 debutante ball when young ladies have completed their years of training and preparation, and are ready to be introduced to the rest of the world, rather than after they are thirty-something, married with children.
Let's explore some of the history. Stuart Kendric has a nice 7-page summary on theHistory & Plumbing of SANs.
IBM announced the first SAN technology calledEnterprise Systems Connection (ESCON) way back in September 1990. This allowed multiplemainframe servers to connect to multiple storage systems over equipment called "ESCON Directors" that directedtraffic from point A to point B. Before this, mainframes sent "ChannelCommand Words" or CCWs, across parallel "bus and tag" copper cables. ESCON was serial overfiber optic wiring. SANs solved two problems: first, it reduced the "rat's nest" of cables between many serversand many storage systems, and second, it extended the distance between server and storage device.
For distributed systems running UNIX or Windows, the CCW-equivalent over parallel cables was called Small ComputerSystem Interface (SCSI). The SCSI command had over 1000 command words, so for its Advanced Technology (AT) personal computers (PC AT), IBM introduced a subset of SCSI commands called ATA (Advanced Technology Attachment). ATA drives supportedfewer commands, ran at slower speeds, and were manufactured with a less rigorous process. Today ATA drives are about 55 percent the cost per MB as comparable SCSI drives.
Anyone who has ever opened their PC and found flat ribbon cable with eight or sixteen wires in parallel, can understand that the same issues applied externally. Parallel technologies arelimited to distance and speed, as all the bits have to arrive at the end of the wire at approximately thesame time. Direct attach schemes with every server attaches directly to every storage device were also problematic.Imagine 100 servers connected to 100 storage devices, that would be 10,000 wires!
So, a new technology standard was developed, called Fibre Channel, ratified in 1994.The spelling of "Fibre" was intentionally made different than "Fiber" on purpose. "Fibre" is a protocol thatcan travel over copper or glass wires. "Fiber" represents the glass wiring itself.
Fibre Channel is amazingly versatile. For today's Linux, UNIX and Windows servers, it can carry SCSI commands, and the combination of SCSI over FC is called Fibre Channel Protocol (FCP). For the mainframe servers, it can carry CCW commands. Running CCW over Fibre Channel is called FICON. This convergence allows mainframes and distributed systems to share a common Fibre Channel network, using the same set of switches and directors.
We saw the use of SANs explode in the marketplace over the past 10 years, and then cool down with a series of mergers and acquisitions. Last year, Brocade announced it was acquiring rival McData, so we will be down to two major players, Cisco and Brocade.
So, IMHO, I think we are well past the "Year of the SAN".
I didn't really have a theme this week, still recovering from jet-lag from my travels through Japan, Australia, China.
Gary Diskman has an amusing blog entry about a Funny disaster recovery job posting. It is not clear if he is being completely tongue-in-cheek, or a bit cynical. However, it rings true that you get what you measure, and some managers look for easy metrics, even if there are unintended consequences.
Western medicine works this way. Rather than paying your doctor to keep you healthy, you pay him per visit, to get refills on prescriptions, check-ups on medical conditions, surgeries and so on. While Eastern medicine is focused on keeping people healthy, Western medicine profits more from resolving "situations".
I have seen similar situations on the "health" of the data center. In one case, the admins were measured on how quickly they bring back up their web-servers after a crash. They had this process down to a science, because they were measured on how quickly they resolved the situation. I suggested switching from Windows to Linux, a much more reliable operating system for web-serving, and showed examples of web-servers running Linux that have been up for 1000 days or more. Management changed the metrics to "average up-time in days" and magically the re-boots all but disappeared, thanks to Linux, but also thanks in part to shifting the incentive structure. Perhaps some of those earlier situations were "artificially created"?
Back in the 1980s, I was working on a small software project that was about 5000 lines of code. In those days, testers were measured by the number of "successful" testcases that ran without incident. Testcases that uncovered an error were labeled as "failures" to be re-run after the developers fixed the code. When I declared my code ready for test, the test team ran 110 testcases, all successfully, and they were all rewarded for meeting their schedule. I, on the other hand, did not accept these results, met with them and told them I would give them $100 each if they could find a bug in my code in the next week. Nobody writes 5000 lines of code without some error along the way, not even me. (As one author put it, more people have left earth's gravity to orbit the planet than have written perfect code that did not require subsequent review or testing. It's so true. Good software is difficult to write.)
The test team accepted the challenge, and found 6 problems, more than I expected, but at least I felt more confident of the code quality after fixing these. As I suspected, the unintended consequence of counting "successful" testcases was that testers would write the most simple, basic, least-likely-to-challenge-boundaries testcases to ensure they meet their numbers. My experiment was costly to me, but more importantly was a wake-up call for the test management, and they realized they needed to re-evaluate their test procedures, metrics and terminology. This was a long time ago, and I am glad to see that the overall "software engineering" practice has matured much over the past 20 years.
So, my advice is to determine metrics that have the intended consequences you want, while avoiding any negative unintented consequences that might undermine your eventual success. People will quickly figure out how to maximize the results, and if you can align their goals to company goals, then everybody benefits.
Well, I'll be blogging from Mexico next week (yes, it is a business trip!). Enjoy the weekend.
The "corporate bloggers" from the various storage vendors often mention their opinions about IBM products. Sometimes, they say something nice, and other times they poke fun. It's good to read the various opinions. Most are well-thought and well-written.
EMC blogger Chuck Hollis has a post about the various categories that industry analyst IDC used for external controller-based disk in their most recentQ4 Storage Scorecard.I agree with Chuck that it is good to have independent analysts that take an objective look across all storage vendors to provide the facts on various makes and models. Both IBM and EMC took marketshare in 4Q, so we cancongratulate ourselves and each other for the efforts needed to make this happen.
Chuck mentions that while EMC and HDS high-end boxes are similar, perhaps IBM's "DS" series is different enough to question putting it in the same "high-end" category. It's not clear if Chuck is poking fun at the fact that theIBM DS family spans multiple categories; or an admission thatthe IBM DS8300 Turbo is faster than the EMC DMX-3 and HDS USP offerings. Perhaps we need a new categorycalled "super high-end"?
IDC doesn't publish their data by price band, but we can infer from the products in each how they decidedwhich products were grouped into which categories. Let's examine the entire IBM DS family in the various categories.
Our newest offering is the IBM System Storage DS3000 series. Some analysts call this category "low end", but IBM prefers using "entry level". These have an attractivelow acquisition price, very easy to set up, and are intended for the Intel and AMD servers, such as IBMBladeCenter, System x, as well as servers from HP and Dell. Disk arrays in this category typically have listprices below $50,000 USD.
Our midrange offering is the IBM System Storage DS4000 series. These are designed for Linux, UNIX and Windows based workloads.Some call these server platforms "open systems", or sometimes "distributed systems". The DS4000 systems are rack-optimized modularunits, providing plenty of options and trade-offs between price and performance for price-sensitive customers.The "high end" model of the DS4000 series is the DS4800, and has very impressive performance characteristics.Disk arrays in this category typically have list prices in the $50,000 to $299,000 USD range.
IBM System Storage DS6000 seriesis one of our enterprise class offerings. DS6000 offers mainframe attachment comparable to what EMC DMX or HDS USP offer for their "enterprise class" or "high end" models, but uses substantially less power and in a much more compact modular rack-optimized packaging. Disk arrays in this category typically have list prices at $300,000 USD and above.
Super High End
Perhaps IBM and EMC can work together to petition IDC to adopt this as a new category, based on performance,rather than list price. Is the storage marketplace ready for a fourth category?As Chuck mentioned on his blog, IBM is #1 for mainframe disk storage, and perhaps it is because the IBM System Storage DS8000 Turbo series does so well on most mainframe workloads. No offering from EMC or HDS meet or beat the SPC benchmarks for the DS8000 Turbo. You can see the results in the Executive Summary or read the Full Report.
Thanks to IBM's innovative Adaptive ReplacementCache algorithm, IBM DS8000 performance shines best handling read-intensive random-access workloads that mainframes do most often. These types of workload are modeled by the SPC-1 benchmark. In cases of write-intensive, sequential processing, the differences are less substantial, as disk arrays from all manufacturers drop down to the native performance capabilities of the 10K and 15K RPM drives.
I'll give you a real example. Not long ago, I waspart of a team to help resolve a performance bottleneck on-site at the customer location. The customer had an interesting "composite application" where data was processed on AIX platform (IBM System p), which passed the data to a Linux partition running on the IBM System z mainframe,which in turn used Java SQL to post updates to a DB2 database on z/OS partition, which then wrote out through FICON adapters to an HDS USP device. IBM and HDS worked together to help the customer figure out why they weregetting disappointing throughput and response times. IBM brought in experts on AIX, TCP/IP, Java, Linux, z/OS and FICON. HDS had their experts too, and tried to improve performance by quadrupling the storage capacity, and spreading the data out across more spindles. That didn't work. As it turns out, HDS disk just couldn't deliver the performance required. The software and mainframe were all well tuned. They replaced the HDS withan IBM DS8000 array, and it met all the service level requirements. Problem solved.
The problem with having this new "super high end" category, of course, is that only IBM plays in it, so it wouldn'toffer the marketplace much of a comparison. For now, we'll just have to settle for being the fastest in the samecategory as EMC DMX and HDS USP.
Storage is a competitive marketplace.Both EMC and HDS are reputable companies that make quality products that attach to IBM System z mainframe servers. Not all workloads are mission-critical or performance-sensitive. For less critical workloads, perhaps you may find EMC or HDS performance is "good enough".
But if performance is important to you, you should consider IBM on your list of vendors for your next purchase decision. Let IBM help you prove it to yourself, running your specific workloads side by side with your existing equipment.
(Note: I am neither a medical doctor nor registered dietician. I can share with you ideas that have worked for me (or people I know) that might help you achieve your goals. I strongly suggest you read books and consult with medical experts as necessary.)
The problem is that most people think of dieting as something you do temporarily. People decide to lose weight, go on a diet, reach their target goal weight, go back to their previous ways, and gain the weight back.
The word Diet comes from the Greek language and means "way of life". Every day that food enters your mouth, you are on a diet. People aren't on or off a diet, but rather switch from one diet to another. The trick is to find a healthy diet that you can live with the rest of your life, so your weight doesn't go up and down.
Most health experts agree that the [Western pattern diet], typical in the United States and other developed countries, is [certainly not healthy]. Washing down that bologna-and-cheese on white bread sandwich with a 44-ounce high-fructose soft drink hasn't served Americans well. This combination of processed meats, refined grains, dairy, and sugar-laden foods has shown to cause obesity and other health problems.
Physicians at Cornell University found that [men take better care of their cars than their bodies]. If you tell a guy that his car takes 12 gallons of high-octane gasoline, 5 quarts of 5W-30 oil, and a 50/50 mix of water and anti-freeze, he would totally understand what you mean.
But tell that same guy that his diet must consist of an appropriate ratio of complete proteins, monounsaturated fats, and carbs with a low glycemic index, and he will scratch his head. Aren't calories just calories?
Unlike a car, where the gasoline, oil and anti-freeze get poured into different openings into fixed metal containers, the human body takes in all of the things it needs in one opening, your mouth, and receives it into a stretchable container, your belly. While carbs are just converted to fuel, the proteins and fats have actual functions and bring building blocks that cannot be built from just carbs alone.
Carbs are found mostly in foods like fruits, grains and vegetables. Not all carbs are the same. Some break down quickly to glucose, the sugar molecule that represents fuel for the rest of your body. Others break down slowly. Consider a fireplace, you put a few pieces of newspaper or kindling, and the larger logs on top. The newspaper is easy to light, but burns quickly. The logs on the other hand burn slowly and give you hours of heat.
Eating the Western pattern diet is like filling your fireplace with newspaper, and having to re-light your fire over and over after all the newspaper burns out.
Proteins are the building blocks of your muscles and other internal organs. These are built from amino acids, and your body can't make them, you have to have them in your diet. Even if you lead a sedentary lifestyle, sit all day at a desk, then sit all evening in front of the television, your body needs to repair internal muscles and organs with proteins, so you need to eat proteins every day to replenish these amino acids.
Complete proteins, such as those in beef, eggs and fish, have all the amino acids represented. Plant-based proteins, like rice, beans, and wheat, are incomplete, lacking one or more of the amino acids you need.
Fats are needed to absorb fat-soluble vitamins, which are important for a variety of functions. Monounsaturated fats can be found in olive oil, nuts, and avocados. While many people feel the saturated fats in red meat and dairy are bad for your health, there are exceptions. Coconut milk is high in saturated fats, but good for you.
There is some dispute and controversy on exactly what is an ideal diet. This can be partly attributable to articles that report findings from observational studies, rather than from double-blind clinical studies. To understand the difference, I suggest you watch Tom Naughton present [Science for Smart People] in this amusing 46-minute video.
Over the past few years, I have tried out several different diets, to figure out which one is best for me. I'll save those details for my next post.
In his blog, Paul Gillin agrees with Time Magazine's Person of the Year choice of "all of us", those of us who use the World Wide Web to do business or have fun, and to those who contribute to the internet by creating content, such as people who blog or create websites.
So, in continuing my theme this week to recap the best and worst of last year, I list my personal "tech highlights" of 2006.
Programming my Tivo Remotely.
Last September, I realized on a 3-week business trip that I had not programmed my Tivo to record the premieres of each of the new season's television shows. If you miss the first few weeks, it might be difficult to make sense of the rest of the season. Fortunately, I was able to program my Tivo remotely through the internet.
Purchasing TV shows on iTunes
Despite this, I had a repeat episode of "House" record instead of a new episode of
Still unable to make sense of what was going on in the TV show "Heroes", I was able to read the "wiki" which explained all the subtle imagery and background implied.
Using Linux to rescue lost Windows data
My disk drive failed on my laptop, and although I had most of my data backed up with Tivoli Storage Manager prior to my business trip, I had some files that I acquired or updated during the business trip. Thankfully, there are Linux "LiveCD" images that allow you to access your Windows files. You boot these LiveCD images from your CD drive, so there is no installation of Linux on the hard drive itself. If you travel as much as I do, consider bringing along some Linux CDs to get you out of trouble.
Connecting my home entertainment system to my Mac
I now have an 802.1g (54Mb) wireless hub which allows my Tivo to connect wirelessly to the internet to get daily updates, but also allows me to play all my music stored on my Mac through my home entertainment system, and I can also listen to thousands of radio stations through "Live365.com". My favorite station is "Depeche Mode Inspired" which plays songs by Depeche Mode, as well as cover versions by a variety of others.
Learning to Blog
Believe it or not, there is a right way and a wrong way to blog, and this year has been a good learning experience. IBM has a fairly healthy blogging policy, but nonetheless, say the wrong thing and I could be in serious trouble. Fortunately, that hasn't happened, and I am glad to see a fairly open exchange of ideas among the set of bloggers that discuss storage issues.
Building a Snowman in Second Life
I have been a member of Second Life now since November, but it wasn't until I entered a competition to build avirtual snowman last week that the potential of this new interface became obvious to me. There is still lots to learn, but at least now I see value in spending more time and effort learning more about it.
Getting an all-in-one printer/scanner to work with both my Mac and IBM PC
I didn't think it could be done, but here it is, my all-in-one Printer/Scanner works correctly, seemlessly, from both my Windows PC and my Mac Mini, and I have it on my home network so my laptop can use it also, wirelessly!
Using Google Language Tools to translate materials to Portuguese
I speak several languages, enough to order food in restaurants and to get around through various modes of transportation, but translation for a technical audience is more challenging. A class we normally conduct in pure English was taken to Sao Paulo, Brazil, and although most students know some amount of English, we thought it would be good to translate the test questions to Brazillian Portuguese. I took the questions and ran them through a number of translation services websites, and had local IBMers review the results. The winner was Google language tools, which required hardly any edits to the generated text. The class was a big success.
Digital Cameras and CD Burners
As I travelled from Brazil to Bolivia last August, I met a young back-packer who was on her way to Peru, but was staying in La Paz for a few days. We had a great time together, and I was able to transfer the digital photos from my Canon PowerShot digital camera into my laptop and burn her a CD to take with her to Peru.
Painting my Dining Room table
After Halloween, I accidently left my pumpkin jack-o-lantern on my kitchen table as I left for a trip, and when I got back, it had decomposed and left a terrible stain on the wood surface. After sanding the table, I determined that the best course of action was just to paint the surface. I could have just painted it a solid color, or maybe a faux finish with two colors, but instead, chose to copy a famous painting, "Le Cafe" by Alberto Magnelli. I was able to scan this into my computer, resize it, and then project the image onto my table, to then outline the image and paint. I know I would not have been able to do this free-hand.
I am sure there are other triumphs I had throughout the year, but these are the first the come to mind.
This week I was in Palm Springs in meetings with clients, prospects, business partners and IBM sales reps.
Tuesday consisted of "outdoor meetings", but the high winds caused some people to arrive late, and others to land in the various sand traps and water hazards. A "welcome reception" event allowed everyone to socialize and get to know the IBM experts and executives. Two of my colleagues, Mike Stanek and Dave Wyatt, were with me also in Australia last week, and so the three of us were discussing recovery from jet lag.
Wednesday was organized as a main tent event, where everyone met into one large room to hear our strategy,latest set of offerings, and customer testimonials. This was done indoors, of course, which was a good thing as the winds were now gusting up to 50 miles per hour, knocking over windmills and making the local news.
Here's a quick sample from the testimonials:
An insurance company virtualized their IBM DS8000, DS4000, ESS 800 and EMC DMX3 high-end disk with theIBM System Storage SAN Volume Controller and got higher availability and performance. Data migrationefforts that used to take six(6) hours of admin time now took less than one hour, and with no system downtime.They have a total of 350TB virtualized under SVC now, but plan to extend this for a variety of other projects.
A bank presented their success using "Global Mirror" (IBM's asynchronous two-site replication disk mirroring capability).Their previous "business continuity" plan was called 2-20-24 for 2 sites that were 20 miles apart and recovery time objective (RTO) of 24 hours. With the events of Hurricane Katrina, this was considered inadequate, and a new2-200-6 plan was requested, across 200 miles with a recovery time objective of only 6 hours. The chose to deploythis one application at a time, to learn and grow by experience in each phase. They started with Microsoft Exchange e-mail application running under VMware on BladeCenter servers, and wereable to recover remotely within 1 hour. They are now looking to refine and automate the recovery process, perhapswith IBM TotalStorage Productivity Center for Replication and Geographically Dispersed Open Clusters (GDOC).
A healthcare provider presented their success with tiered storage, managing a 475TB mix of IBM DS8000, DS6000,DS4000 and HP EVA disk arrays. The key was having centralized storage management from IBM, which allowedthem to shrink provisioning time from 3 weeks average, to now 96% of their storage provisioning requests are completedin less than 1 week. Moving data between storage tiers was non-disruptive, and the significantcosts savings greatly justified the change in "mindset" that required some training on the new environment.
Thursday we offered a series of "workshops" on specific topics. These were interactive sessions to discuss installation, design and deployment of various solutions. The event ended early enough so that people couldreturn home, or go to the practice range, which reminded me of this inspiring video on How to play golf as well as Tiger Woods.
The event got great reviews, and I look forward to the next one. Until then, enjoy the weekend!
This week and next I am touring Asia, meeting with IBM Business Partners and sales repsabout our July 10 announcements.
Clark Hodge might want to figure out where I am, given the nuclearreactor shutdowns from an earthquake in Japan. His theory is that you can follow my whereabouts just by following the news of major power outages throughout the world.
So I thought this would be a good week to cover the topic of Business Continuity, which includes disaster recovery planning. When making Business Continuity plans, I find it best to work backwards. Think of the scenarios that wouldrequire such recovery actions to take place, then figure out what you need to have at hand to perform the recovery, and then work out the tasks and processes to make sure those things are created and available when and where needed.
I will use my IBM Thinkpad T60 as an example of how this works. Last week, I was among several speakers making presentations to an audience in Denver, and this involved carrying my laptop from the back of the room, up to the front of the room, several times. When I got my new T60 laptop a year ago, it specifically stated NOT to carry the laptop while the disk drive was spinning, to avoid vibrations and gyroscopic effects. It suggested always putting the laptop in standby, hibernate or shutdown mode, prior to transportation, but I haven't gotten yet in the habit of doing this. After enough trips back and forth, I had somehow corrupted my C: drive. It wasn't a complete corruption, I could still use Microsoft PowerPoint to show my slides, but other things failed, sometimes the fatal BSOD and other times less drastically. Perhaps the biggest annoyance was that I lost a few critical DLL files needed for my VPN software to connect to IBM networks, so I was unable to download or access e-mail or files inside IBM's firewall.
Fortunately, I had planned for this scenario, and was able to recover my laptop myself, which is important when you are on the road and your help desk is thousands of miles away. (In theory, I am now thousands of miles closer to our help desk folks in India and China, but perhaps further away from those in Brazil.) Not being able to respond to e-mail for two days was one thing, but no access for two weeks would have been a disaster! The good news: My system was up and running before leaving for the trip I am on now to Asia.
Following my three-step process, here's how this looks:
Step 1: Identify the scenario
In this case, my scenario is that the file system the runs my operating system is corrupted, but my drive does not have hardware problems. Running PC-Doctor confirmed the hardware was operating correctly. This can happen in a variety of ways, from errant application software upgrades, malicious viruses, or in my case, picking up your laptop and carrying it across the room while the disk drive is spinning.
Step 2: Figure out what you need at hand
All I needed to do was repair or reload my file sytem. "Easier said than done!" you are probably thinking. Many people use IBM Tivoli Storage Manager (TSM) to back up their application settings and data. Corporate include/exclude lists avoid backing up the same Windows files from everyone's machines. This is great for those who sit at the same desk, in the same building, and would be given a new machine with Windows pre-installed as the start of their recovery process. If on the other hand you are traveling, and can't access your VPN to reach your TSM server, you have to do something else. This is often called "Bare Metal Restore" or "Bare Machine Recovery", BMR for short in both cases.
I carry with me on business trips bootable rescue compact discs, DVDs of full system backup of my Windows operating system, and my most critical files needed for each specific trip on a separate USB key. So, while I am on the road, I can re-install Windows, recover my applications, and copy over just the files I need to continue on my trip, and then I can do a more thorough recovery back in the office upon return.
Step 3: Determine the tasks and processes
In addition to backing up with IBM TSM, I also use IBM Thinkvantage Rescue and Recovery to make local backups. IBM Rescue and Recovery is provided with IBM Thinkpad systems, and allows me to backup my entire system to an external 320GB USB drive that I can leave behind in Tucson, as well as create bootable recovery CD and DVDs that I can carry with me while traveling.
The problem most people have with a full system backup is that their data changes so frequently, they would have to take backups too often, or recover "very old" data. Most Windows systems are pre-formatted as one huge C: drive that mixes programs and data together. However, I follow best practice, separating programs from data. My C: drive contains the Windows operating system, along with key applications, and the essential settings needed to make them run. My D: drive contains all my data. This has the advantage that I only have to backup my C: drive, and this fits nicely on two DVDs. Since I don't change my operating system or programs that often, and monthly or quarterly backup is frequent enough.
In my situation in Denver, only my C: drive was corrupted, so all of my data on D: drive was safe and unaffected.
When it comes to Business Continuity, it is important to prioritize what will allow you to continue doing business, and what resources you need to make that happen. The above concepts apply from laptops to mainframes. If you need help creating or updating your Business Continuity plan, give IBM a call.
