An avid reader of this blog pointed me to a blog post [A Small Tec DIGG on IBM XIV], byGowri Ananthan, a System Engineer in Singapore.Basically, she covers past battles, er.. discussions between me and fellow blogger BarryB from EMC, and [blegs] foranswers to three questions.
Gowri, here are your answers:
Q1. Does IBM offer a Pay-as-you-Go [PAYGO] upgrade path for its IBM XIV disk storage system?
The concern was expressed as:
PAYGO also requires the customer to purchase the remaining capacity within 12 months of installation. So it is More of a 12-month installment plan than pay-as-you-grow.
A1. Actually, IBM offers several methods for your convenience:
With IBM's Capacity on Demand (CoD) plan, you get the full framewith 15 modules installed on your data center floor, but only pay for the first four modules 21 TB, then pay for 5.3TB module increments as you need them over the next 12 months. This is ideal for companies that don't know how fast they will grow, but do not want to wait for new modules to be delivered and installed when needed.
With IBM's Partial Rack offering, you can get a system with as little as six modules (27TB),and then over time, add more modules as you need. This does not have to be done within 12 months, you can stay at six modules for as long as you like, and you can take as long asyou want to add more modules. When you are ready for more capacity, the drawer or drawerscan be delivered, and installed non-disruptively.
Neither of these are "payment installment plans", but certainly if you want to spread yourcosts into regularly-scheduled monthlypayments across multiple years, IBM Global Financing can probably work something out.
Q2. Does IBM consider the XIV as green storage?
The concern was expressed as:
You are powering (8.4KW) and cooling all 180 drives for the whole duration, whether you're using the capacity or not. is it what you called Greener power usage..?
A2. Yes. IBM considers the IBM XIV as green storage. The 8.4KW per frame is lessthan the 10-plus KW that a comparable 2-frame EMC DMX-950 system would consume. Theenergy savings in IBM XIV comes from delivering FC-like speeds using slower SATA disks that rotate slower, and therefore take less energy to spin.
In the fully-populated or Capacity on Demand configuration, you would spin all 180disks. However, using the partial rack configuration, the 6-module has only 40 percent ofthe disks, and therefore consumes only 40 percent of the energy. If you don't plan to storeat least 20-30 TB, you might consider the DS3000, DS4000, DS5000, or DS8000 disk system instead.
Q3. How do you connect more than 24 host ports to an IBM XIV?
The concern was expressed as:
And finally do not forget my question on 24-FC Ports… Up to 24 Fiber Channel ports offering 4 Gbps, 2Gbps or 1 Gbps multi-mode and single-mode support.Stop.. stop.. how you gonna squeeze existing bunch of FC cables in 24 ports?
A3. Best practices suggest that if you have ten or more physical servers, each with two separate FC ports, then you should use a SAN switch or director in between. If you require four ports per server, then you would need a SAN switch beyond six servers to connect to the IBM XIV. If you consider that 24 FC ports, at 4Gbps, represents nearly 10 GB/sec of bandwidth, you will recognize that this is not a performance bottleneck for the system.
While the rest of Americans were glued to their televisions watching President Obama explain his plan for recovery, my colleagues and Ihad dinner with clients from Canada.
One in particular claimed her father was known as the kingpin of[Flin Flon]. She lives in Ontario now, but she grew up in this smallmining town in Manitoba made famous for winning a government contractto grow crops for medicinal purposes.
Shown at left is the town's mascott, Flinty. Yes, apparently thetown was named after a fictional character of a paperback novel.
Of course, in conversations with clients, it is best to avoid topics like politics or drugs,but the intersection of government health care and implications on IT can't be disregarded.Since Canada has a more efficient healthcare process, the government enjoys a lower costper citizen. President Obama has suggested that the United States should adopt reforms to make the American system more efficient, including electronic medical records.
Not surprisingly, [smarter healthcare] is part of IBM's latest set of strategic initiatives.Digitizing medical information has a variety of benefits:
Information isn't stranded on islands
If there is any situation that needs to deliver the right information, to the right people,at the right time, healthcare is certainly one of them. Having the right information canhelp reduce medical mistakes.
Physicians spend time with their patients, not paperwork
I personally know some doctors here in Tucson, and they are the first to admit that theywould prefer to focus on their core strengths, which they spent many years in medical school,and leave the administrative details to someone else. Focusing on core strengths is acommon theme for successful businesses, and this is no different.
Expertise needs no passport
Medical emergencies do not always happen near the hospital or clinic that your medical records are stored at.An exciting feature of digital information is that it is easy to transport to where it isneeded, unlike paper records or X-ray film.

With mixed emotions, Jon Peake announced he will retire from IBM next week. Jon is known as thefather of IBM Virtual Tape Server (VTS), the industry's first virtual tape system, announced in 1996and generally available in 1997.One of my 19 patents was for the VTS pre-migration capability, and as lead architect for DFSMS, I worked closely with Jon and his tape systems team to ensure its success.
From left to right:
Chris Telford, IBM Development manager for Enterprise Tape Integration
Jon Peake, IBM Distinguished Engineer and Master Inventor
Annette Estelle, Jon's global admin assistant
At his retirement celebration, Jon was awarded the coveted "Project Bulldog" jacket, which has an interesting history.
In response to IBM's 1996 VTS announcement, the top StorageTek (STK) tape sales teams and most of the dedicated tape technicians were invited to a global assembly at a fancy resort in Winter Park, CO (about 90 miles west of STK's Louisville headquarters) in early 1997. The gathering was named Project Bulldog, after Ron Korngiebel, STK's director of competitive marketing, who I am told had voice and facial resemblance to justify the project moniker. Ron had recruited Fred Moore, Steve Blenderman, and other prized engineers as speakers. I have seen both Fred and Steve speak at various conferences such as SHARE and GUIDE, and agree they are high quality speakers.
The goal was to have STK's brightest in Louisville go down in the trenches, work the field guys into a frenzy, defend STK Tape at any cost, and send IBM packing. At the end of the two day fest, many participants received the coveted Project Bulldog jacket.
Former STKers who now work at IBM can remember this meeting involved:
Bashing of the [IBM Seascape] architecture approach. The use of commodity servers and componentsto build storage systems continues today in the IBM System Storage DS8000, SAN Volume Controller,XIV, and TS7650 Deduplication solutions.
Explanations how and why IBM's VTS would never work, and how only STK virtual tape would make it in the market. Today, IBM is the leader in storage virtualization, both for disk and tape.
Mock interview videos with claims that IBM could never figure out how to attach IBM drives to the STK Silo. I was a big proponent of this, having visited customers who specifically asked for IBM to sell its better, faster IBM drives into their existing STK silos. At first, upper management was hesitant to do this, but the IBMengineers worked out what changes were needed, and today many STK tape automation libraries run with IBM tape drives.
While some analysts frowned on Sun's [2005 acquisition of StorageTek], IBM was delighted, given Sun's previous track record in storagecompany acquisitions. I joke that we are still picking up confetti in the hallways of IBM's Tucsonlab. I was in New York city when I heard Sun's announcement, and it didn't take long for STKemployees offering me their resumes.Since then, many STK engineers, technicians and sales team have left Sun, many coming over to IBM.Back then, there were many intelligent and talented people working for StorageTek, and IBM is gladto have hired them.
With the resurgence of interest in tape systems, from dealing with new legislation for long term retention of electronic data to a focus on energy efficiency, Jon leaves much like a champion retiring at the top of his game.
Jon, I am going to miss you! Enjoy your retirement!
Well, it's Tuesday again, and that means more IBM announcements!
Today, IBM announced the enhanced IBM System Storage DS3200 disk system.It is in our DS3000 series, the DS3200 is SAS-attach, DS3300 is iSCSI-attach, and DS3400 is FC-attach. All of them support up to 48 drives, which can be a mix of SAS and SATA drives.
The DS3200 supports the following operating environments (see IBM's [Interop Matrix] for details):
Linux (both Linux-x86 and Linux on POWER)
With today's announcements, the DS3200 can be used to boot from, as well as contain data. This is ideal to combine with IBM BladeCenter. With the IBM BladeCenter you can have 14 blades, either x86 or POWER based processors, attached to a DS3200 via SAS switch modules in the back of the chassis.
Let's take an example of how this can be used for a Scale-Out File Services[SoFS] deployment.
First, we start with servers. We can have either three [IBM System x3650] servers, but this would use up all six of the direct-attach ports. Instead, we'll choose the [BladeCenter H chassis], with three HS21 blades for SoFS, and that leaves us with eleven empty blade slots we could put in a management node, or other blades to run applications.
SAS connectivity modules
The IBM BladeCenter [SAS Connectivity Module] allows the blade servers to connect to a DS3200. Two of them fit right in the back of the BladeCenter chassis, providing full redundancy without consuming additional rack space.
DS3200 and EXP3000 expansion drawers
We'll have one DS3200 controller with twelve internal drives, and three expansion EXP3000 drawers with twelve drives each, for a total of 48 drives. Using 1TB SATA, this would be 48 TB raw capacity.
The end result? You get a 48TB NAS scalable storage solution, supporting up to 7500 concurrent CIFS and NFS users, with up to 700 MB/sec with large block transfers. By using BladeCenter, you can expand performance by adding more blades to the Chassis, or have some blades running SAP or Oracle RAC have direct read/write access to the SoFS data.
Just another example on how IBM can bring together all the components of a solution to provide customer value!
I’ve just returned from the IBM Tivoli Pulse conference in Las Vegas – a meeting of over 4000 customers, partners, and IBM employees. ... There was a lot to digest, but three of the major themes caught my attention, and my imagination. ... First, IBM put a huge push behind their Dynamic Infrastructure initiative. Sounds like so many other automation and autonomic initiatives of the past, right? Well, things are getting better, and “dynamic” is becoming more of a realistic possibility, especially with the emergence of cloud computing and cloud services models. ... Second, a lot of time was spent on IBM’s Service Management Industry Solutions. When I first heard of this, my thought was that IBM was creating solutions for the Service Management industry (i.e. food services, janitorial services, hospitality services). But this is much larger than that – much, much larger. IBM is taking their unique ability to pair business (non-IT) expertise with IT consulting, planning, and technology delivery, and constructing (careful – here comes the “f” word) frameworks for several vertical industry segments. ... IBM is perhaps the only organization in the world that can take this on fully and hope to deliver a meaningful result. But beyond that, this represents a huge opportunity for IT professionals to become the transformation agents within their own organizations, contributing at a whole new level. ... Lastly, I was really impressed by IBM’s Smarter Planet initiative. The primary thought here was that the key to a greener planet is to take inefficiencies out of just about every form of business through the intelligent application and deployment of technology. At first I was thinking this was just another marketing initiative, but in the course of this event, listening to the keynotes and talking to a number of IBM execs, it became apparent that this is a substantial cultural shift within IBM itself. Just think about that for a moment – when 400,000 employees all change their direction and focus, their sheer mass is going to make a noticeable difference. ... Magic (Johnson) gave an excellent talk, and reminded the audience that you should do two things no matter what your job or role. First, service starts with knowing your customers – not just who they are, but what they do and what is important to them. And second – always over-deliver. Go that extra step. Exceed expectations. The boost in loyalty, goodwill, and improved customer relationships will be well worth the effort. Good thoughts to keep with us….
If you missed Pulse 2009, perhaps because your company has put a clamp down on travel expenses, you are in luck! IBM is hosting the "Dynamic Infrastructure Forum" March 3-4, 2009, on your computer. This is an IBM Virtual event, no travel required! [Register Today!]
Fellow blogger Chuck Hollis from EMC has a post titled[Whither Frankenstorage] causing quite a stir in the [Stor-o-Sphere]. He is not the firstEMC blogger to use this phrase, I credit [BarryB] for coining the term back in September 2008.Frankenstein serves as the ideal icon for EMC's FUD machine. In the novel, Dr. Frankenstein wasattempting to do something nobody else had ever attempted, to create human life from variousdead body parts, a process full of uncertainty and doubt, with frightful results.
Perhaps it was a coincidence that I discussed IBM's storage strategy in my post[Foundations and Flavorings] on January 28, shortly followed by NetApp's announcing V-series gateway [support of Texas Memory Systems' RamSan-500] on February 3. These two events mighthave been the trigger that pushed ChuckH over the edge to put pen to paper, .. finger to keyboard.
Flinging FUD in all directions was ChuckH's not-so-subtle way to remind the world that EMC is the only major storage vendor to not offer a successful storage virtualization product. Withoutfirst-hand experience with well-designed storage virtualization, ChuckH conjectures that a configuration matching intelligent front-ends to reliable back-ends might be more expensive, might be more difficult to manage, or might be harder to support.
(Note: Rest assured, IBM can demonstrate that a modular approach, combining intelligent front-ends to reliableback-ends can help reduce costs, be easier to manage, and be fully supported. Contact yourlocal IBM Business Partner or storage sales rep for details.)
My favorite was from Nigel Poulton's post on[Ruptured Monkey]. Here's an excerpt:
In fact, I'm fairly certain that EMC don't back away from customers who run HP or IBM servers and say "sorry we cant help you here, an end to end HP or IBM solution would be much better for you when it comes to troubleshooting……. putting our storage in would only add extra layers of complexity and make things messy….."
On most other days, ChuckH has well-written, insightful blog posts that show that EMC brings some value to the industry. I could have made a snarky reference to[Dr Jekyll and Mr Hyde], or indicate this post proves that nobody at EMC is editing or reviewingChuck's thoughts before they get posted. But it's too late, Chuck already got the message, and added the following to bring the discussion back to civility:
When considering the broad range of storage media service levels available today (flash, FC, SATA, spin-down, etc.) what's the best way to offer these media choices in an array? Is the answer (a) combine smaller arrays from different vendors together behind a virtualization head, or (b) invest the time and effort to build arrays that can directly support all of these media types?
Would anyone like to try a cogent response to the question posed, please?
To address ChuckH's question, Nigel's post gave me the idea to use today's 200th year celebration of [Charles Darwin].
Over millions of years, Charles Darwin argued, evolution results in change in the inherited traits of a population of organisms from one generation to the next.A key component of this is a biological process called [mitosis] that allows a single cell to split and become two cells. In some cases, these individual daughter cells can then specialize to specific functions, such as nerve cells, muscle cells or bone cells. Over time, adaptations that work well carry forward, and thosethat don't get left behind.
I find it interesting that before [On the Origin of Species] was published in 1859, works of fiction like Mary Shelley's[Frankenstein] had monsters being"created", and afterward, monsters were the result of mutation or selective adaptation.
Nigel compares EMC's monolithic approach to placing an intelligent front-end with a reliable back-end as "One man band, where one guy is trying playing all the instruments himself" versus the "Philharmonic Orchestra". I would take it one step further, comparing single-cell organisms to multi-cell life forms.
Innovative companies like Google and Amazon can't wait for a completely integrated solution from a major IT vendor to meet their needs. Why should they? There are open standards, and ways to interconnect the best intelligence into a [dynamic infrastructure®.].You don't need to wait another million years to see which way the IT marketplace considers the better approach. Just look at the last 60 years. Back then, computer systems were all integrated, server, storage, and the wires that connected them were all inside a huge container. Then, mitosis happened, and IBM created external tape storage in 1952, and external disk storage in 1956. Open standards for interfaces allowed third party manufacturers like HDS, StorageTek and EMC to offer plug-compatible storage devices.
On the server side, it didn't take long for functionality in mainframes to split off. Mitosis happened again, with front-end UNIX systems processing incoming data, and mainframes handling the back-end data bases and printing. The client-server era replaced dumb terminals with more intelligent desktops and workstations, and these could handle the front-end processing to display information, with the back-end storage and number-crunching being handled by the UNIX and mainframe systems they connected to.Connections between desktops and servers, and from servers to storage, have also evolved. From thousands of direct-attach cables to networks of switches and directors.
Charles Darwin was particularly interested in cases where evolution happened faster or slower than in other cases. While IBM and Microsoft encouraged third-party innovations on the PC side, Apple resisted mitosis, trying to keep its machines pure single-cell, integrated solutions.For the same reasons that you can't fight the laws of nature, Apple ended up having to support I/O ports to external devices. Thanks to open standards like USB and Firewire, you can connect third-party storage to Apple computers. My little Mac Mini at home has more devices hanging off it than any of my Windows or Linux boxes! And Apple's iPod is successful because its iTunes software runs on both Windows and Mac OS operating systems.
Every time mitosis happens in the IT industry, it opens up opportunities to specialize, to innovate, to adapt to a dynamically changing world. When mitosis is suppressed, you get limiting products and frustratedengineers leaving to form their own start-up companies.But when mitosis is encouraged, you get successful products, solutions and partnerships positioned for a smarter planet.
These disk capacities can have up to 25x times their effective capacity with IBM's HyperFactorin-line deduplication capability. So the smallest 7TB model could be as effective as 175TB of traditionaldisk storage.
IBM Tivoli Storage Manager (TSM) v6
After years and years in development, IBM announces[TSM v6]. Here's a quick summary of the key features:
DB2 instead of an internal database
For years, people have complained that IBM used its own internal relational database. This was becausewhen TSM was first launched back in 1993, the DB2 did not have all the features on all of the various server platforms that TSM needed. Today, DB2is the leading relational database on all the key platforms that TSM server runs on, and therefore good enough for use within Tivoli Storage Manager. If you don't already have DB2, it is included for use with TSM v6.1 at no additional charge. Do you have to become a DB2 expert to use TSM? No! The TSM administration commands have been updated to hide all the complexity of DB2 away, behind the scenes. You now just use TSM commands to administer the database,as you did before. IBM will provide conversion utilities to help existing TSM customers migrate to thisnew database environment.
Better Operational Reporting
Another big complaint was that TSM had fixed reporting, and administrators that wanted customized reportsoften had to resort to purchasing third party products. With the change over to DB2, TSM now enables youto create your own reports using Eclipse's Business Intelligence and Reporting Tools[BIRT]! If you haven't used BIRT, you can downloada free open source copy and start playing around with its capabilities. This is combined with a revamped GUI that provides a customizable dashboard using IBM's Integrated Solutions Console (ISC)infrastructure.
Lastly, IBM has incorporated deduplication capability within the TSM v6.1 software for its own diskstorage pools. This is done in a post-process manner so as to dedupe all of your legacy backup dataas well, not just the new stuff, without impacting the current TSM server performance.
At this point, you might be thinking "Wait, what about IBM TS7650 ProtecTIER deduplication?" which is really two questions.
Can I use TSM v6.1 with IBM TS7650 ProtecTIER?
Yes, however since TSM progressive incremental method is vastly more efficientthan other backup products like Veritas NetBackup or EMC Legato NetWorker, the TS7650 may only get 10x reductionof TSM backups, versus up to 25x with full-backups-every-night backup schemes. TSM only dedupes itsdisk storage pools, so it won't dedupe data directed at tape systems like the TS7650 or othertape libraries. This avoids the "double dedupe" concern.
When should I use TSM's software version versus TS7650's hardware deduplication?
This is a positioning question. For now, the cut-over point is about 10TB per night backup processing. If youbackup more than 10TB per night, TS7650 hardware may be the better approach. If you are a smaller customer nowhere near that volume of data, then using TSM v6.1 software deduplication may be a morecost-effective solution. If you start small, and grow beyond 10TB per night, it is easy to bring ina TS7650 into an existing TSM environment and migrate the data over.
If you run TSM server on a logical partition (LPAR) or virtual guest OS under VMware ESX, Xen or Microsoft'sHyper-V environment, why should you have to license it for the whole box? With TSM v6.1, you nowcan pay for only the amount of processors you use, down to a single core even.If you currently run TSM v5 on z/OS, you can migrate over to TSM v6.1 server for Linux on System z totake advantage of cost savings using IFL engines.
IBM Tivoli Key Lifecycle Manager (TKLM) v1.0
Don't let the "v1.0" scare you, this is the successor to IBM's Encryption Key Manager (EKM) that hasthousands of clients using today with IBM encrypting tape drives. The new TKLM adds support for full disk encryption (FDE) drives--like those for the DS8000 I mentioned in [yesterday's post]--as well as new features to support key rotation for compliance and business controls.
IBM Tivoli Storage Productivity Center
Last, but not least, we have IBM Tivoli Storage Productivity Center [TSPC]. No, that is not a typo. IBM is renaming IBM TotalStorage Productivity Center to Tivoli Storage Productivity Center toavoid trademark conflicts with the [Professional Golfer's Association].
This is not just renaming existing product. Here some key improvements:
TSPC brings back together Productivity Center Standard Edition (Disk, Tape, SAN and Data) with Productivity Center for Replication, which were separate at birth a few years ago.
TSPC adds support for IBM's Storage Enterprise Resource Planner[SERP] from theNovusCG acquisition.
End-to-end view for EMC storage devices connected to supported servers via EMC Powerpath multipathing driver. As customers switch away from EMC Control Center over to IBM's Productivity Center, IBM can continue to provide support for existing EMC gear.
Of course, IBM will still offer IBM System Storage Productivity Center[SSPC] which is a piece of hardware pre-installed with Productivity Center software.
Hopefully, you can now see why I had to split up all these announcements into separate posts acrossmultiple days!
Now that IBM XIV has proven that 1TB SATA are safe for high-end tier-1 enterprise class use, we extended DS8000 support to include SATA support also. DS8000 supports RAID-6 and RAID-10 for these.
Intelligent Write Caching
IBM Research conducts extensive investigations into improved algorithms for cache management. Intelligent Write Caching boosts performance for both temporal and spatial locality.
Remote Pair FlashCopy®
This allows you to FlashCopy volume A to volume B, with Volume B remotely mirrored to Volume C at a secondary location, via Metro Mirror. This allows you to have a consistent copy of your data at both locations.
IBM was the first in the industry to deliver tape-drive encryption, so it makes sense that IBM is also the first in the industry to deliver disk-drive encryption. These are 15K rpm drives in standard 146GB, 300GB and 450GB capacities. As with tape, encrypting at the disk device eliminates the huge overhead from server-based encryption methods.
Solid State Drive (SSD)
You can also have Solid State Disk drives in your DS8000, in 73GB and 146GB capacities, protected by RAID-5.If you are wondering what data to put on these much-faster drives, IBM has taken the work and worry out by havingintelligence in DB2 to optimize what gets placed on SSD to get the most performance improvement.
IBM System Storage XIV
Continuing the incredible marketplace excitement over its Cloud-Opimized Storage[XIV series], IBM now has announced[new capacity options]. The IBM XIV R2 that we announced last August 2008 was a fixed 15 module configuration. In thenew configurations, you can start with as little as six modules, representing a 40% partial rack of the originalfull model. Here is a table that shows the details:
Useable Capacity (TB)
Fibre Channel Ports
Cache Memory (GB)
IBM System Storage N series
And last, but not least, we have two new models in IBM's[N6000 series].The [N6060]has model A12 (single controller) and model A22 (dual controller). These are disk-less controllers thatyou can configure in either appliance mode or gateway mode. In appliance mode, you can attachdisk drawers such as the EXN1000, EXN2000 or EXN4000. In gateway mode, you attach external disk systems, suchas the IBM DS8000 or XIV above.
It's ruggedized to handle earthquakes. IBM brings a feature that we've had for a while on other disk systems to the N series with a collection of bolts and anchors to secure the rack from physical tremors.
It's instrumented for IBM Active Energy Manager, a component of IBM Systems Director. New iPDUs are designed to help measure and monitor energy management components. As companies get more concerned about thefate of the planet, monitoring energy consumption can help reduce carbon footprint.
I'll cover the rest of the announcements tomorrow!
It seems like [only yesterday] I was talking about IBM's strategic initiatives for the New Enterprise Data Center, including the launch of asset and service management at [Pulse 2008] in Orlando, Florida.
This week, my colleagues are at [Pulse 2009] in Las Vegas, Nevada. (I'm not there this time, so stop asking all my colleagues where I am!)Obviously, a lot has change in the last 12 months: the world's financial economy has collapsed, our delicate environment continues to unravel, and a new US President was elected to fix all that was broken by the former occupant. As a result, IBM's strategy has evolved beyond just data centers for large enterprises.
I can't think of a better time to emphasize the need for a more dynamic infrastructure. And this is not just focused on IT operations, but smarter business infrastructure as well, as the two now are very much intertwined. Everything from smarter healthcare, smarter telecom, smarter retail, smarter distribution, smarter transportation, and smarter financial services. IBM's [Dynamic Infrastructure@reg;] is one of four strategic initiatives to help build a smarter planet.
Let's take a quick look at the key benefits:
Do you remember back to the days that the IT department was like the accounting department in the back office, merely recording what happened in a series of transactions? Not anymore! Today, IT is front and center of most businesses, helping to generate revenue, drive innovation, and provide better customer service. We are finding a convergence between the physical world of running business with the digital world of IT. Intelligence is everywhere, embedded in systems and operations throughout, not just in a data center.
Imagine only 10-15 years ago the primary concern for IT operations was the cost of hardware. Now, thanks to[Moore's law], hardware is cheaper, but other IT budget costs like labor, management software, power and cooling costs are growing faster and becoming more predominant factors. IBM recognizes that you must consider thetotal cost of ownership, not just the acquisition cost of new hardware. But again, this isn't just reducing the costs of IT, but making more effective use of IT resources to reduce costs everywhere else, in schedulingtransportation, in managing manufacturing assets, and so on.
While the world feels much safer now that Barack Obama has taken over, there are still risks and threats out there, and businesses large and small have to manage them. Economic swings like we have experienced lately help weed out those companies that had fixed costs and static infrastructures, in favor of those with more variable costs and dynamic infrastructures. When the marketplace slows down, can your business "dial down" its operations to match? And when the recession is over and business is booming again, can your business "ramp up" fast enough to take on new opportunity? With IBM's Cloud Computing, companies can minimize their fixed investments and use a variable amount of computing as business needs change dynamically.
To learn more about Dynamic Infrastructure, read the IBM [Press Release].
When I was a kid, I used to love old spy movies where they would hide a small microchip or microfiche behind the stamp on a letter or postcard. "Yeah right," I would think to myself, "how much information could that little thing possibly hold."On their post[Bringing the "New Intelligence" Down to Earth: Intro to Semantic Web, Internet-of-Thing], My fellow IBM bloggers Jack Mason and Adam Christensen pointed me to a crazy new product called "Mir:ror" that connects to your PC or laptop.
At first, I thought it was a another product spoof, like Onion News Networks'video of the [Apple MacBook Wheel] that eliminatesthe need for a keyboard.But no, this product is real, from a company called [Violet]. The mir:ror, the internet-connected rabbits, and the tiny postage stamps called "ztamps" with embedded RFID chips that allow everything to be interconnected.I can see a lot of interesting uses for the ztamps. Squishing CD-romsor memory sticks inside presentation folders was always awkward. Butthese are small, flat and discrete. I don't know how many GBs of storage each ztamp holds, but they look cool, don't they?
Just another example of becoming a smarter planet!
IBM's emphasis on "Information Infrastructure" is to help organizations get the right information, to the right people at the right time. This helps them to have the right insights, make the right decisions, and develop the right innovations needed for the challenges at hand.
As the planet got smaller and flatter, IBM led the way. Now, as the planet needs to get smarter--with more efficient health care, energy distribution, financial institutions, and IT infrastructures--IBM will once again take the lead.
In an effort to deal with "Great Depression 2.0", US President Barack Obama invited IBM Chairman Sam Palmisano and dozen other CEOs to the White House yesterday to talk about the economic stimulus package.
Barack's response was insightful on his thoughts on this. Here are someexcerpts:
"A few moments ago, I met with some of the leading business executives in the country. And it was a sober meeting because these companies and the workers they employ are going through times more trying than any we've seen in a long, long while. ... And yet, even as we discussed the seriousness of this challenge, we left our meeting confident that we can turn our economy around. ... But these executives also understand that without wise leadership in Washington, even the best-run businesses can't do as well as they might. ... And that is why I hope to sign an American Recovery and Reinvestment Plan into law in the next few weeks. And most of the money we're investing as part of this plan will get out the door immediately and go directly to job creation, generating or saving 3 (million) to 4 million new jobs. And the vast majority of these jobs will be created in the private sector because, as these CEOs well know, business, not government, is the engine of growth in this country. ... But even as this plan puts Americans back to work, it will also make the critical investments in alternative energy, in safer roads, better health care and modern schools that will lay the foundation for long-term growth and prosperity, and will invest in broadband and emerging technologies, like the ones imagined and introduced to the world by people like Sam and so many of the CEOs here today, because that's how America will retain and regain its competitive edge in the 21st century. ... We will invest in what works. Instead of politicians doling out money behind a veil of secrecy, decisions about where we invest will be made public on the Internet and will be informed by independent experts whenever possible. And we will launch a sweeping effort to root out waste, inefficiency and unnecessary spending in our government. And every American will be able to see how and where we spend taxpayer dollars, by going to a new website to [recovery.gov], because I firmly believe what Justice Louis Brandeis once said, that sunlight is the best disinfectant. ... In the end, the answer to our economic troubles rests less in my hands or in the hands of our legislators than it does with America's workers and the businesses that employ them. They are the ones whose efforts and ideas will determine our economic destiny, just as they always have. For in the end, it's businesses, large and small, that generate the jobs, provide the salaries and serve as the foundation on which the American people's lives and dreams depend. All we can do, those of us here in Washington, is to help create a favorable climate in which workers can prosper, businesses can thrive and our economy can grow."
I certainly find Sam's efforts and Barack's responsiveness encouraging.
We've been quite busy here at the Tucson Executive Briefing Center. I am often asked to explain the relationship between IBM's various storage products. While automakers don't have to explain why they sell sports coupes, pickup trucks and minivans, this analogy does not adequately cover IT storage products. So, I have come up with a new analogy that seems to be a better fit: foundations and flavorings.
All over the world, meals are often comprised of a foundation, perhaps rice, potatoes or pasta, covered with some form of flavoring, sauces, pieces of meat or fish, grated cheese and spices. In Puerto Rico, I had dishes where the foundation was mashed bananas called [plantains]. Sandwich shops often let you pick your choice of bread, the foundation, and then your meats and cheeses, the flavorings.At our local steakhouse,[McMahon's], the menulists a set of steaks, the foundation such as Rib Eye, Filet Mignon, Prime Rib or New York Strip, andvarious flavorings, such as sauces and rubs to cover the steak. Last night, I had the Delmonico steak with the Cristiani sauce consisting of Portobello mushrooms, garlic and aged Romano cheese.
This serves as a useful analogy for IBM's storage strategy. Allowing thefoundations and flavorings to be separately orderable greatly simplifies the selection menu and providesa nearly any-to-any approach to meeting a variety of client needs.Let's take a look at both.
IBM's foundation products are the DS family [DS3000, DS4000, DS5000, DS6000 and DS8000 series], [DS9900 series], and [XIV] for disk, and the TS family [TS1000, TS2000, TS3000] series for tape drives and libraries. In much thesame way you might prefer brown rice instead of white rice, or linguine instead of penne pasta, you might find the attributes of one storagefoundation more attractive based on its performance, scalability and availability features for yourparticular application workloads.
Fellow IBM blogger Barry Whyte discusses SVC at great length on his [Storage Virtualization] blog. Flavoring disk foundation storage with SAN Volume Controller can provide you additionalfeatures and functions, and help improve the scalability, performance or availability characteristics.For example, if you have DS4000, DS8000 and XIV, you might use SVC to provide a consistent methodologyfor asynchronous replication, a form of consistent "flavoring" if you will.
N series Gateways
The [N series gateways] offerflavoring to disk foundation, including unified NAS, iSCSI and FCP protocol host attachment, and application aware capabilities. (As for our IBM N series appliances or "filers", these could be foundational storage behind an SVC, but that's perhaps a topic for another post.)
SoFS provides a global namespace with clustered NAS access to files. This is a blended disk-and-tape solution with built-in backup and Information Lifecycle Management [ILM]. Policies can be used to place different files onto different tiers of storage, automate the movement from tier to tier, including migration to tape, and even expiration when the data is no longer needed.
The [IBM System Storage DR550] provides Non-erasable, Non-rewriteable (NENR) flavoring to storage. While the DR550 comes with internal disk storage, it can front end a tape library filled with WORM cartridges. The DR550 hasbeen paired up with small libraries (TS3200 or TS3310) as well as larger libraries like the TS3500.
The IBM Grid Medical Archive Solution [GMAS] provides a variety of capabilities for storing and accessing medical images, using a blended disk-and-tape approach. This allows hospital and clinicnetworks to provide access for doctors and radiologists from multiple locations.
Many of the flavorings are called "gateways". The IBM TS7650G flavors disk that provides a virtualtape library[VTL] with inline data deduplication capability. Recent performance tests pairing the TS7650G flavoring with XIV foundation storage found this combination to be an excellent match.
Let me know what you think. Does this help you understand IBM's storage strategy and acquisitions? Enteryour comments below.
In the post [Flowing Workflow], the folks over at Eightbar point to the latest 3D work being done with IBM Lotus Sametime.
IBM Sametime is IBM's instant messaging facility, which has been extended to include Voice over IP (VOIP) capability similar to Skype, and now is being developed as a launch point for 3D impromptu meetings "in-world", similar to [Second Life].
With many companies facing hard times and considering travel restrictions for face-to-faceinternal meetings, an information infrastructure that adopts this technology might be a reasonable alternative.
Today we watched Barack Obama get inaugurated as the 44th President of the United States, and he reminded all Americans that the power and strength of this country comes through its diversity.To some extent, this is also what gives IBM its power and strength as well. While not quite the orator of President Obama, IBM's own CFO, Mark Loughridge, gave a rousing speech about IBM's 4Q08 and year-end financial results.
In 2008, IBM was not just successful because it had a wide diversity of servers and storage hardware products, but also a diversity of software, and a diversity of service offerings.And lastly, IBM sells to a diversity of clients in different industries, throughout a diversity of markets. While the current economic meltdown might have affected businesses focused on the US and other major markets, IBM did particularly well last year in growth markets, including the so-called BRIC countries (Brazil, Russia, India and China).
IBM's approach to invest in R&D and its nearly 400,000 employees for long-term success continues to pay off. Where "Cash is King", IBM can also afford all those acquisitions and strategic initiatives, positioning the company for a brighter future.
Where there are challenges, IBM finds opportunity.
IBM has launched a new blog, focused on making [a smarter planet]. In my post,[The New Year in Six Words], Idiscussed the part of Sam Palmisano's speech that mentioned a small $30 Billion investmentcould result in 950,000 new jobs. For those who wondered how IBM arrived to that figure,here are two posts:
Today, fellow IBMer Ken Hannigan celebrated his 25th year anniversary with IBM, which inducts him into the IBM Quarter Century Club[QCC]. I was surprised to hear that there are over 900 QCC members currently residing in Arizona. In the past, QCC was shortly followed by retirement,but in these economic times, it marks a mid-point in one's career.
I met Ken back in 1988, I was working on DFHSM and he was part of theDFDSS team that moved from San Jose, California to Tucson, Arizona.Later, Ken and I would work in the same department as architects forthe DFSMS product that included DFSMShsm and DFSMSdss components.
Ken was then offered a chance to lead the effort to launch a new productfrom an internal project called Workstation Data Save Facility (WDSF) thatwas changed to Data Facility Distributed Storage Manager (DFDSM),then renamed to ADSTAR Distributed Storage Manager (ADSM), and finally tothe name it has today: [IBM Tivoli Storage Manager].
Over the years, Ken's had some interesting experiences. Two examples:
Saving the Democracy of Peru
During a hotly contested election in the Latin American country of Peru, there were technical problems with the ballot records. Management needed someone from Tucson to go, and my namewas floated around, since I spoke Spanish fluently. My schedule did not permit,so they sent Ken instead. Ken was able to recover the lost ballot information and avoid a revolution.
Assisted with the Technical team for a Major Motion Picture
Ken was part of the IBM technical team that helped [DreamWorks SKG] producethe movie [The Prince of Egypt],a major animated motion picture. IBM is heavily involved in the digital mediacommunity, and was instrumental in helping film-makers set up theirinformation infrastructure.
Ken has been one of my best friends over the past twenty years. I introduced him to hiswife, and was the best man at his wedding. It is quality people like Ken that makeworking at IBM so special.
I've gotten some strange emails lately, so I thought I would address them here.
Dear Tony, In your last post about [New Years Resolutions for 2009], you mention spending more time with friends and family, which is typically a phrase usedby people leaving a company.
Are you announcing your retirement?
No, I don't plan to retire anytime soon. Like most companies, IBM had [changed its retirement plans]. Those lucky enough to be on the old plan could retire after 30 years of service to IBM, and get 12 percent of their last five year's salary as an annual pension the rest of their lives. If you averaged $100K per year the last five years, then you could retire on $60K per year. Many IBMers in Tucson took their pension and moved to Mexico, and lived like kings!
To qualify for the old plan, you had to be a certain age, have a minimum number of years service working for IBM, or be an executive of Italian-American descent. I missed it by a few months, so I am on the new plan instead. This involves employer contribution matches to a 401(k) plan and reflects the trend from working for a single company all your life, tochanging careers or companies every 5 to 10 years.Many of my colleagues on the old plan had announced early last year their plans to retire by the end of 2008, but then changed their minds after the economic downturn.
For both personal and professional reasons, I plan to travel less in 2009,so that will give me more time to reconnect with friends and family, especially my friends over at[Tucson Fun and Adventures], the premiere singles activities club in Southern Arizona; the [Tucson Laughter Club], recognized as one of the oldest laughter clubs in the United States; and the Tucson Film Society at the[Loft Cinema].
Dear Tony, Why not make a New Years Resolution for an "exercise regime"?
I made that lifestyle change back in 2003, joining [Performance at McMahon's] fitnesstraining facility, and have been lifting weights there, several times per week, ever since.
This is my personal trainer Christine. Our gym had their annual Elite Performer athletic contest running August to November last year, and I came in fifth place. If you are looking fora personal trainer in the Tucson area to jump-start your own fitness goals, call Christine at 907-4510.
Normally, I considerNew Years Resolutions for starting new things, changing bad behaviors, or revisiting things I have long forgotten, not really intended for continuing to do the same as the year before. However, if it makes you happy, I resolve to continue my exercise regime of lifting weightsthree times a week, and will try to do more [cardio] as well.
Dear Tony, What's up with your fellow blogger Chuck Hollis from EMC and his post[Timely Reading], suggesting we should read Ayn Rand's hefty novel Atlas Shrugged?
What's your take on this?
I don't talk with Chuck personally about his posts, so I can only guess that he is underthe same blackout period rules, which typically commences the day following the end of the fiscal quarter and ends after the issuance of a news release disclosing the quarterly financial results.
That said, Chuck is an avid reader, and often recommends books he likes. For example,based on his recommendation, I read Tim Harford's [The Undercover Economist] and found it an excellent choice.In the book Atlas Shrugged, Ayn Rand renounces religion, socialism and a variety of other ills facing societyin 1950s America. Since [93 percent] of scientists and engineers are Atheist,Agnostic or other form of non-believer, I suspect most readers of the Storage blogosphere areat least somewhat familiar with Ayn Rand's works. Personally, I prefer the works of fellow atheist authors[Douglas Adams], [Sir Isaac Asimov], [Richard Dawkins], and [George Orwell].
Chuck mentions he saw Stephen Moore's article ['Atlas Shrugged': From Fiction to Fact in 52 Years in the Wall Street Journal, which considers this tometo be the second most influential book, second only to the Bible. No doubt many of the bailoutplans proposed today sound similar to the government acts covered in the novel. One warningrings true for me:
When profits and wealth and creativity are denigrated in society, they start to disappear -- leaving everyone the poorer.
However, I suspect his postmight also be partly motivated by Josh Bernoff's report [Time To Rethink Your Corporate Blogging Ideas] from Forrester Research. I've read the full report, andit has some interesting results.Only 16 percent of those surveyed who use company blogssay they trust them. The situation improves slightly if you look at people who are activein the blogosphere.Among those who read blogs regularly, only 24 percent trust company blogs. And only 39 percent of bloggers, who actually write their own blogs, trust company blogs. This ranks lower than every other form of content Forrester asked about, includingbroadcast and print media, direct mail, and email from companies.
This would mean company blogs are justslightly more trustworthy than self-proclaimed UFO alien abductees, tabloidsat the grocery store checkout lane, and perhaps politicians like Vice President Dick Cheneyor former Secretary of Defense Donald Rumsfeld.Josh insists that this report is not meant as a plea for existing corporate bloggers to give up blogging, but rather to be more thoughtful on how and why they blog.
Perhaps Chuck is suggesting that bloggers are like the creative types in Atlas Shrugged who felt under-appreciated, and that perhaps all IT Storage bloggers should go on strike?
Well, I'm not retiring, not quitting my exercise routine, and not planning to stop blogging.Last year, thanks to you my dear readers, I was ranked the third most influential blog on IBMDeveloperworks. Congratulations to my fellow IBM bloggers [Bobby Wolf] and ["Turbo" Todd Watson], who ranked first and second!
This is our so-called black-out period that prevents me from talking about how well IBM is doing or making predictions about our industry that might affect stock prices, so instead I will talk about my New Year's Resolutions.
Contribute to the OLPC Foundation
Last year, I resolved to contribute my time and effort to the One Laptop Per Child[OLPC] project led by Nicholas Negroponte. It didn't takelong for them to contact me, and I had wonderful experiences helping the folks in Nepal andUruguay.Despite building and delivering half a million laptops to deserving kids, the OLPC team has been impacted by the recent economic meltdown. From their [announcement], theOLPC team is making some shifts in their direction and priorities. Here's an excerpt:
"This restructuring is also the result of an exciting new direction for OLPC. Our technology initiatives will focus on:
Development of Generation 2.0
A no-cost connectivity program
A million digital books
Passing on the development of the Sugar Operating System to the community.
With regard to deployments:
Latin America will be spun off into a separate support unit
Sub-Saharan Africa will become a major learning hub
The Middle East, Afghanistan and Northwestern Pakistan will become a major focus"
It's not clear how involved I will be with OLPC in 2009, and I will probably wait for the dust to settle on this one.
Eat Healthier and Drink more
I hired a nutritionist and improved my diet. I also drank more (that was an easy one to keep!). Unfortunately, there is still room for improvement on this one.
Attend more movies and film-making events
I've renewed my membership with the Tucson Film Society, and attended several of their eventsin 2008, including a meeting Will Conroy, screenwriter for the Action/Suspense thriller[Transsiberian] starring Woody Harrelson and Ben Kingsley.
Get better Organized
Well I carried my [Hipster PDA] in my back pocket most of 2008, but it just did not catch on. I did get somewhat better organized, with three-ring binders and a scanner that converts paper documents into searchable PDF files.
While some might find the concept of New Year's resolutions silly or pointless, I find themuseful. Here's some interesting research on Wikipedia:
"Recent research shows that while 52 percent of participants in a resolution study were confident of success with their goals, only 12 percent actually achieved their goals. Men achieved their goal 22 percent more often when they engaged in goal setting, a system where small measurable goals are used (lose a pound a week, instead of saying "lose weight"), while women succeeded 10 percent more when they made their goals public and got support from their friends."
Here are mine for 2009:
Spend More Time with Friends and Family
According to this [article by Albrecht Powell], reconnecting with friends and family is the number one on the Top 10 list.I think the economic meltdown served as a great wake-up call for people to focus what is mostimportant in your life and adjust your priorities accordingly.
Enjoy Life More
Back in 2007, I vowed to laugh more. While the current economic crisis might not seem like an appropriate time for this one, I think there is hope, a new US President, and some much-needed enthusiasm for change.
Learn Something New
At a dinner with clients, one of the IBMers had brought his 20-something daughter and hersimilarly-aged friend. Their college was closed for the week after a student shooting, andhe felt it best to give them a change of scenery. They couldn't wait until they were "done withschool" so they could get on with their lives. I had to break the bad news to them that intoday's world, they should expect life-long learning. Gone are the days where you can learna specific skill or trade, and do that the rest of your life. Hopefully I didn't frightenboth into giving up a career in favor of marriage with such advice!
With the world getting smaller, flatter, and yes "smarter" also, I resolve to learn somethingnew. I don't necessarily know what that is yet, but I will keep it in the back of my mind.
Make Tucson a better place, and enrich the lives of its residents
I've actually gotten complaints that I was helping people in other countries, through OLPC and [Kiva],and that I should domore for people right here in Tucson. That's fair. This year I resolve to investigatethat further.
Get Better Organized
Last year was a good start, but I can certainly do better in 2009, both at home and at the office.Perhaps I need to dust off my old copy of ["Getting Things Done"] by David Allen and read it again!
I hope everyone had some time these past few weeks of the Winter Solstice to enjoy some time off with friends and family. I had a great trip to New York City, got to visit my brother and his friends, went to see my friends in Michigan to celebrate New Years Eve, and see the world premiere of [LexiBaby], an independent film from fellow filmmaker Jonathan Petro.
The latter of course from fellow IBMers, corporate executives receiving bailout money, attorneys that specialize in foreclosures, and the lucky few who will be in Washington DC for the US Presidential Inauguration.In addition to all the bailout money from banks, insurance companies and automakers that will be spent on IBM equipment and services, there might be additional funds from the US Government to improve our country's information infrastructure.In a recent Forbes article titled[The Tech Solution To The Recession], Andy Greenberg writes about US president-elect Barack Obama's ideas about a stimulus to the economy. Here's an excerpt:
"IBM, for starters, believes that a massive infusion of cash should go toward cutting-edge technology. Last month, IBM CEO Sam Palmisano presented a report to Obama's transition team from the Information Technology and Innovation Foundation (ITIF) that argues that a $30 billion investment in universal broadband, health information technology and a smarter power grid could create 950,000 jobs.
"Those disparities, and IBM's argument for focusing a stimulus plan on technology in general, come from what economists have dubbed "network multipliers." The computing giant, and ITIF, argue that technology creates more jobs than other types of infrastructure by enabling new types of businesses.
"If you build more roads, people don't buy more tires or GPS systems, but if you build better networks, you create entirely new business applications," says Rob Atkinson, president of ITIF and an author of the think tank's report. "Something like YouTube could never have existed without broadband."
"Regardless of precisely how tech stimulus money gets spent, IBM will likely sweep up a significant chunk of those taxpayer funds, given the computing giant's diverse hardware, software and services businesses. Other IT infrastructure giants like Microsoft, Hewlett Packard, Oracle and SAP are also likely to vie for pieces of Obama's stimulus package aimed at technology.
"But among those tech companies, IBM has been especially active in driving home the need for national investment in tech systems. In a November speech to the Council on Foreign Relations, Palmisano argued that that the U.S. needs to invest in innovation not just as a solution to our current recession but as a competitive measure in an increasingly integrated and technologically advanced world."
Wrapping up this week's theme on ways to make the planet smarter, and less confusing, I present IBM's third annual [five in five]. These are five IBM innovations to watch over the next five years, all of which have implications on information storage. Here is a quick [3-minute video] that provides the highlights:
"If you've spent any time in the storage biz, you probably realize that the server vendors sell more storage than they have any right to."
This is the old [Supermarkets-vs-Specialty Shops] debate I discussed over a year ago. The debate goes along the lines that some peopleprefer to buy their entire information infrastructure (servers, storage, software and services)from a single vendor, one-stop shopping, while others might prefer to buy their pieces ascomponents from different vendors that specialize in each technology. Because of this, Specialty shops tend to focus on other Specialty shops as their primary competitors (EMC vs. NetApp), whileSupermarkets tend to focus on other Supermarkets (IBM vs. HP).
The apparent contradiction is that Chuck feels the Supermarkets (IBM, HP, Sun and Dell) should not have any right to sell storage, in the same manner that butchers, bakers and candlestick makersdo not believe that Supermarkets should have any right to sell meat, bread or candles?If servers and storage are so different, how can self-proclaimed storage-only specialist EMC have the right to sell their non-storage offerings, from server virtualization (VMware) to cloud-computing services? With EMC's latest announcement of DW/BI centers, I think we can safely take EMC off the list of storage-only specialists. We will needto come up with a third category for those caught in limbo between being one-stop shopping Supermarkets like IBM and being a pure storage-only Specialists like NetApp. Perhaps EMC has become the IT equivalent of Wal-Mart's[Neighborhood Market].(No offense intended to my friends at Wal-Mart!)
Then Chuck continues with these statements:
"It is rarely is it the case that a server vendor can offer you a better storage product, or better service, or better functionality than what a storage specialist can do.
...Interestingly enough, Dell appears to do a sizable amount of storage business "off base" with EMC products -- outside the context of a specific server transaction."
This second contradiction relates to products that are manufactured by specialty shops, butsold through supermarket channels. Chuck would like to imply that the only storage products anyone should consider is gear made by specialty shops, whether you get it directly from them, or through Supermarket's with appropriate OEM agreements. Storage made by Supermarkets, either organicallydeveloped or through acquisitions, should not be considered? What happens when a Supermarket acquires a specialty shop? We've already seen how negative EMC has been against IBM's acquisitions of XIV and Diligent, which allowed a Supermarket like IBM to provide better products in both cases than what is available from any specialty shop. Kind of pokes a big hole in that argument!
But Dell also acquired EqualLogic, which Chuck admits might have a "fit in the marketplace".As it turns out, companies would rather buy EMCequipment from Dell sales people, than from EMC directly, and perhaps this is becauseDell, like IBM, sees the big picture. Dell, IBM and the rest of the IT Supermarkets understand theentire information infrastructure, not just the storage components of a data center. With HP and Sun selling HDS gear, and IBM selling NetApp gear, it becomes obvious that EMC needs Dell more than Dell needs EMC.
Chuck then pokes fun at NetApp in comparing the EMC NX4 to NetApp's FAS2020, comparable to IBM System Storage N series N3300. Here's an excerpt:
Like other Celerras, it does the full unified storage thing: iSCSI, NAS and "real deal" FC that isn't emulated.
The irony, of course, is that the NX4 does not actually use "real" Fibre Channel drives,but rather SAS and SATA drives. I guess Chuck's concern is that the NetApp, which doesuse "real" Fibre Channel drives, provides FC-attached LUNs to the host through its WAFL mapping,rather than through EMC's traditional RAID-rank mapping approach.How Chuck can imply that anything in the IT industry that is "emulated" is somehow seriouslyworse than "real", but then spend 40 percent of his posts devoted to the benefits of VMware,which offers "emulated" virtual machines, seems to be yet another contradiction.
"Cloud computing" has been ill-defined and over-hyped, yet storage vendors have been quick to trot out their own "cloud storage" offerings and end users are wondering whether there's significant cost savings in these services for them, particularly in tough economic times.
"Cloud-speak" can be downright confusing....
"Surprisingly, Gartner considers the amorphous nature of the term to be good news: 'The very confusion and contradiction that surrounds the term 'cloud computing' signifies its potential to change the status quo in the IT market,' the IT research firm said earlier this year."
Consistent with Scott Adams's original prediction, the barriers of entry have lowered for storage vendors as well.Rather than competing on function and price through valued relationships and trusted expertise, some vendors would rather confuse instead. EMC tries to paint the NX4 as being "just as good as" anNetApp or IBM N series for unified storage, and EMC tries to create new categories, like Cloud-Oriented Storage (COS), to give their me-too products the impression they are in a league of their own.All of this to discourage customers from making their own comparisons and doing their own research.
IBM doesn't play that way. If you want straight talk aboutIBM's products, contact your local IBM Business Partner or sales rep.
Continuing this week's theme, my team here at theTucson Executive Briefing Center (TEBC) have made these two videos for me, usingcloud-computing facilities from OfficeMax and the folks at JibJab.Only five people were allowed per video, so we had to make two to get everyone in.
If you have been to the Tucson Executive Briefing Center, perhaps you can recognizesome of our faces!
This wraps up my week in Las Vegas for the 27th Annual [Data Center Conference]. This conference follows the common approach of ending at noon on Friday, so that attendees can get home to their families for the weekend, or start their weekend in Las Vegas early to watch the 50th annual Wrangler National Finals Rodeo.
I attended the last few sessions. Here is my recap:
Where, When and Why do I need a Solid-State Drive?
The internet provides transport of digital data between any devices. All other uses have evolved from this aim. Increasing data storage on any node on the Web therefore increases the possibilities at every other point. We are just now beginning to recognize the implications of this. The two speakers co-presented this session to cover how Solid State Disk (SSD) may participate.
Some electronic surveys of the audience provided some insight. Only 12 percent are deploying SSD now. 59 percent are evaluating the technology. A whopping 89 percent did not understand SSD technology, or how it would apply to their data center. Here is the expected time linefor SSD adoption:
17 percent - within 1 year
60 percent - around 3 years from now
21 percent - 5 years or later
The main reasons cited for adopting SSD were increasing IOPS, reducing power and floorspace requirements, and expanding global networks. Here's a side-by-side comparison between HDD and SSD:
Disk array with 120 HDD, 73GB drives
Disk array with 120 SSD, 32GB drives
Per 73GB drive
Per 32GB drive
100MB/sec per drive
Read 250 MB/sec per drive Write 170 MB/sec per drive
300 IOPS per drive
35,000 IOPS per drive
12 Watts per drive
2.4 Watts per drive
However, the cost-per-GB for SSD is still 25x over traditional spinning disk, andthe analysts expected SSD to continue to be 10-20x for a while. For now, they estimatethat SSD will be mostly found in blade servers, enterprise-class disk systems, andhigh-end network directors.
The speakers gave examples such as Sun's ZFS Hybrid, and other products from NetApp,Compellent, Rackable, Violin, and Verari Systems.
Taking fear out of IT Disaster Recovery Exercises
The analyst presented best practices for disaster recovery testing with a "Pay Now or Pay Later"pre-emptive approach. Here were some of the suggestions:
Schedule adequate time for DR exercises
Build DR considerations into change control procedures and project lifecycle planning
Document interdependencies between applications and business processes
Bring in the "crisis team" on even the smallest incidents to keep skill sharp
Present the "State of Disaster Recovery" to Senior Management annually
The speaker gave examples of different "tiers" for recovery, with appropriate RPO and RTOlevels, and how often these should be tested per year. A survey of the audience found that70 percent already have a tiered recovery approach.
In addition to IT staff, you might want to consider inviting others to the DR exerciseas reviewers for oversight, including: Line of Business folks, Facilities/Operations, Human Resources, Legal/Compliance officers, even members of government agencies.
DR exercises can be performed at a variety of scope and objectives:
Tabletop Test - IBM calls these "walk-throughs", where people merely sit around the table and discuss what actions they would take in the event of a hypothetical scenario. This is a good way to explore all kinds of scenarios from power outages, denial of service attacks, or pandemic diseases.
Checklist Review - Here a physical inventory is taken of all the equipment needed at the DR site.
Stand-alone Test - Sometimes called a "component test" or "unit test", a single application is recovered and tested.
End-to-End simulation - All applications for a business process are recovered for a full simulation.
Full Rehearsal - Business is suspended to perform this over a weekend.
Production Cut-Over - If you are moving data center locations, this is a good time to consider testing some procedures. Other times, production is cut-over for a week over to the DR site and then returned back to the primary site.
Mock Disaster - Management calls this unexpectedly to the IT staff, certain IT staff are told to participate, and others are told not to. This helps to identify critical resources, how well procedures are documented, and members of the team are adequately cross-trained.
For exercise, set the appropriate scope and objectives, score the results, and then identifyaction plans to address the gaps uncovered. Scoring can be as simple as "Not addressed","Needs Improvement" and "Met Criteria".
Full Speed Ahead for iSCSI
The analyst presented this final session of the conference. He recognized IBM's early leadership in this area back in 1999, with the IP200i disk system. Today, there are many storage vendors that provide iSCSI solutions, the top three being:
23 percent - Dell/EqualLogic
15 percent - EMC
14 percent - HP/LeftHand Networks
This protocol has been mostly adopted for Windows, Linux and VMware, but has been largelyignored by the UNIX community. The primary value proposition is to offer SAN-like functionality at lower cost. When using the existing NICs that come built-in on most servers, iSCSI canbe 30-50 percent less expensive than FC-based SANs. Even if you install TCP-Offload-Engine (TOE) cards into the servers, iSCSI can still represent a 16-19 percent cost savings. ManyIBM servers now have TOE functionality built-in.
Since lower costs are the primary motivator, most iSCSI deployments are on 1GbE. The new10Gbps Ethernet is still too expensive for most iSCSI configurations. For servers runninga single application, 2 1GbE NICs is sufficient. For servers running virtualization with multiple workloads might need 4 or 5 NICs (1GbE), or consider 2 10GbE NICs if 10Gbps is available.
The iSCSI protocol has been most successful for small and medium sized businesses (SMB) lookingfor one-stop shopping. Buying iSCSI storage from the same vendor as your servers makes a lot of sense: EqualLogic with Dell servers, LeftHand software with HP servers, and IBM's DS3300 or N series with IBM System x servers.The average iSCSI unit was 10TB for about $24,000 US dollars.
Security and Management software for iSCSI is not as fully developed as for FC-based SANs.For this reason, most network vendors suggest having IP SANs isolated from your regular LAN.If that is not possible, consider VPN or encryption to provide added security.Issues of security and management imply that iSCSI won't dominate the large enteprise data center. Instead, many arewatching closely the adoption of Fibre Channel over Ethernet (FCoE), based on revised standardsfor 10Gbps Ethernet. FCoE standards probably won't be finalized till mid-2009, with productsfrom major vendors by 2010, and perhaps taking as much as 10 percent marketshare by 2011.
I hope you have enjoyed this series of posts. In addition to the sessions I attended, theconference has provided me with 67 presentations for me to review. Those who attended couldpurchase all the audio recordings and proceedings of every session for $295 US dollars, and those who missed the event can purchase these for $595 US dollars. These are reasonable prices, when you realize that the average Las Vegas visitor spends 13.9 hours gambling, losing an average of $626 US dollars per visit. The audio recordings and proceedings can provide more than 13.9 hours of excitement for less money!
The booths at a typical week-long tradeshow only go from day 2 to day 4, so that day 1 and day 5 can be used for unpacking and repacking all of the demo equipment and displays. This was the case here at the27th annual [Data Center Conference] here in Las Vegas.
The solution showcase ended Thursday afternoon.
From left to right:George Lane, Ron Houston, Cris Espinosa, Patty Congdon, David Bricker, Paula Koziol, Steve Sams, Tony Pearson,Gary Fierko, Diane Hill, David Share, Nick Sardino, Carla Fleming, Bruce Otte.
Gary Fierko and I discuss the IBM's vision and strategy, the TS7650G ProtecTIER gateway, and the differences between LTO-4 and IBM Enterprise tape, with an attendees at the booth.
Behind the scenes were folks from the [George P. Johnson company] that run events.Deniese Dunavin here helped us be successful at this conference!
Here are just a portion of all the sponsors that made this event possible, printed on bags given to each attendee.
After the booths closed down, we were invited to several different hospitality suites, sponsoredby different vendors.
The Cisco hospitality suite had an Elvis impersonator and a beautiful bride. Her name was Trixie.
The bouncers at the Computer Associates (CA) hospitality suite wore the same shade of green and blue colors from their logo.
The APC hospitality suite went with an Island/Pirate theme.
The Brocade hospitality suite rocked the Casbah! Yes, that is a REAL snake she is holding.
Michael Nixon, a presenter from NEC Corporation of America.
By the time we got to the Data Domain hospitality suite, they were out of "dedupe-tinis", most ofthe attendees had left, but they were giving out these bumper stickers. For those considering Data Domain,you might want to look at the IBM TS7650G Virtual Tape gateway, which also provides inline datadeduplication, but about six times faster ingest rate.
Lagasse, Inc. sells janitorial supplies, such as mops, cleaning chemicals, waste receptacles, and garbage can liners. Of the 1000 employees of Lagasse nationwide, about 200 associates were located in New Orleans at their main Headquarters, primary customer care center, and primary IT computing center.
Amazingly, Lagasse did not have a formally documented BCP (Business Continuity Plan) but more of aBCI (Business Continuity Idea). They chose to take a ["donut tire"] approach, putting older previous-generation equipment at their DR site. They knew that in the event of a disaster,they would not be processing as many transactions per second. That was a business trade-offthey could accept.
Evaluating all the different threat scenarios for impact and likelihood, and focused on hurricanes and floods.They had experienced previous hurricanes, learning from each,with the most recent being 2004 Hurricane Ivan and 2005 Hurricane Dennis. From this, they wereable to categorize three levels of DR recovery:
Tier 1 - The most mission-critical, which for them related to picking, packing and shipping products.
Tier 2 - The next most important, focused on maintaining good customer service
Tier 3 - Everything else, including reporting and administrative functions
The time-line of events went as follows:
The US Government issues warning that a hurricane may hit New Orleans
August 27 - 7pm
Lagasse declares a disaster, starts recovery procedures to an existing IT facility in Chicago, owned by their parent company. A temporary "Southeast" Headquarters were set up in Atlanta.Remote call centers were identified in Dallas, Atlanta, San Antonio, and Miami.
August 28 - just after midnight
In just five hours, they recovered their "Tier 1" applications.
August 28 - 7:30pm
In just over 24 hours, they recovered their "Tier 2" applications.
August 29 - 6am
The Hurricane hits land. With 73 levees breached, the city of New Orleans was flooded.
The following week
Lagasse was fully operational, and recorded their second and third best sales days ever.
I was quite impressed with their company's policy for how they treat their employees during a disaster. For many companies, people during a disaster prioritize on their families, not their jobs.If any associate was asked to work during a disaster, the company would take care of:
The safety of their family
The safety of their pets. (In the weeks following this hurricane, I sponsored people in Tucson to go to New Orleans to attend to lost and stray dogs and cats, many of which were left behind when rescuers picked up people from their rooftops.)
Any emergency repairs to secure the home they leave behind
Marshall felt that if you don't know the names of the spouse and kids of your key employees, you are not emotionally-invested enough to be successful during a disaster.
For communications, cell phones were useless. They could call out on them, but anyone with acell phone with 504 area code had difficulty receiving calls, as the calls had to be processedthrough New Orleans. Instead, they used Voice over IP (VoIP) to redirect calls to whichever remote call center each associate went to. Laptops, Citrix, VPN and email were considered powerful tools during this process. They did not have Instant Messaging (IM) at the time.
While the disk and tapes needed to recover Tiers 1 and 2 were already in Chicago, the tapes for Tier 3 were stored locally by a third-party provider. When Lagasse asked for thier DR tapes back, the third-party refused, based on their [force majeure] clause. Force majeure is a common clause in many business contracts to free parties from liabilityduring major disasters.Marshall advised everyone to strike out any "force majeure" clauses out of any future third-party DR protection contracts.
Hurricane Katrina hit the US hard, killing over 1400 people, and America still has not fully recovered. The recovery of thecity of New Orleans has been slow. Massive relocations has caused a deficit of talent inthe area, not just IT talent, but also in the areas of medicine, education and other professions. The result has been degraded social services, encouraging others to relocate as well. Some have called it the "liberation effect", a major event that causespeople to move to a new location or take on a new career in a different field.
On a personal note, I was in New Orleans for a conference the week prior to landfall, and helped clients with their recoveries the weeks after. For more on how IBM Business Continuity Recovery Services (BCRS) helped clients during Hurricane Katrina, see the following [media coverage].
It's Thursday here at the [Data Center Conference] here in Las Vegas. Trying to keep up with all the sessions and activities has been quite challenging. As is often the case, there are more sessions that I want to attend than I physically am able to, so have to pick and choose.
Making the Green Data Center a Reality
The sixth and final keynote was an expert panel session, with Mark Bramfitt from Pacific Gas and Electric [PG&E], and Mark Thiele from VMware.
Mark explained PG&E's incentive program to help data centers be more energyefficient. They have spent $7 million US dollars so far on this, and he has requested another$50 million US dollars over the next three years. One idea was to put "shells" aroundeach pod of 28 or so cabinets to funnel the hot air up to the ceiling, rather than havingthe hot air warm up the rest of the cold air supply.
The fundamental disconnect for a "green" data center is that the Facilities team pay for the electricity, but it is the IT department that makes decisions that impact its use. The PG&E rebates reward IT departments for making better decisions. The best metric available is"Power Usage Effectiveness" or [PUE], which is calculated by dividing total energy consumed in the data center, divided by energy consumed by the IT equipment itself.Typical PUE runs around 3.0 which means for every Watt used for servers, storage or network switches, another 2 Watts are used for power, cooling, and facilities. Companies are tryingto reduce their PUE down to 1.6 or so. The lower the better, and 1.0 is the ideal.The problem is that changing the data center infrastructure is as difficult as replacingthe phone system or your primary ERP application.
While California has [Title 24], stating energy efficiency standards for both residential and commercial buildings, it does notapply to data centers. PG&E is working to add data center standards into this legislation.
The two speakers also covered Data Center [bogeymans], unsubstantiated myths that prevent IT departments fromdoing the right thing. Here are a few examples:
Power cycles - some people believe that x86 servers can typically only handle up to 3000 shutdowns, and so equipment is often left running 24 hours a day to minimize these. Most equipment is kept less than 5 years (1826 days), so turning off non-essential equipment at night, and powering it back on the next morning, is well below this 3000 limit and can greatly reduce kWh.
Dust - many are so concerned about dust that they run extra air-filters which impactsthe efficiency of cooling systems air flow. New IT equipment tolerates dust much betterthan older equipment.
Humidity - Mark had a great story on this one. He said their "de-humidifier" broke,and they never got around to fixing it, and they went years without it, realizing they didn't need to de-humidify.
The session wrapped up with some "low hanging fruit", items that can provide immediate benefit with little effort:
Cold-aisle containment--Why are so few data centers doing this?
Colocation providers need to meter individual clients' energy usage -- IBM offers the instrumentation and software to make this possible
Air flow management--Simply organizing cables under the floor tiles could help this.
Virtualization and Consolidation.
High-efficiency power supplies
Managing IT from a Business Service Perspective
The "other" future of the data center is to manage it as a set of integrated IT services,rather than a collection of servers, storage and switches.IT Infrastructure Library (ITIL) is widely-accepted as a set of best practices to accomplish this "service management" approach. The presenter from ASG Software Solutions presented their Configuration Management Data Base (CMDB) and application dependency dashboard. Theyhave some customers with as many as 200,000 configuration items (CIs) in their CMDB.
The solution looked similar to the IBM Tivoli software stack presented earlier this yearat the [Pulse conference].Both ASG and IBM "eat their own dog food", or perhaps more accurately "drink their own champagne", using these software products to run their own internal IT operations.
For many, the future of a "green" data center managed as a set of integrated service are years away, but the technologies and products are available today, and there is no reasonto postpone these projects any longer than necessary. For more about IBM's approach togreen data center, see [Energy EfficiencySolutions]. You can also take IBM's[IT Service Management self-assessment] to help determine whichIBM tools you need for your situation.
Continuing my coverage of the 27th annual[Data Center Conference], the weather here in Las Vegas has been partly cloudy,which leads me to discuss some of the "Cloud Computing" sessions thatI attended on Wednesday.
The x86 Server Virtualization Storm 2008-2012
Along with IBM, Microsoft is recognized as one of the "Big 5" of Cloud Computing. With theirrecent announcements of Hyper-V and Azure, the speaker presented pros-and-cons between thesenew technologies versus established offerings from VMware. For example, Microsoft's Hyper-Vis about three times cheaper than VMware and offers better management tools. That could beenough to justify some pilot projects. By contrast, VMware is more lightweight, only 32MB,versus Microsoft Hyper-V that takes up to 1.5GB. VMware has a 2-3 year lead ahead of Microsoft, and offers some features that Microsoft does not yet offer.
Electronic surveys of the audience offered some insight. Today, 69 percent were using VMware only, 8 percent had VMware plus other, including Xen-based offerings from Citrix,Virtual Iron and others. However, by 2010, the audience estimated that 39 percent would be VMware+Microsoft and another 23 percent VMware plus Xen, showing a shift away from VMware'scurrent dominance. Today, there are 11 VMware implementations to Microsoft Hyper-V, and thisis expected to drop to 3-to-1 by 2010.
Of the Xen-based offerings, Citrix was the most popular supplier. Others included Novell/PlateSpin,Red Hat, Oracle, Sun and Virtual Iron. Red Hat is also experimenting with kernel-based KVM.However, the analyst estimated that Xen-based virtualization schemes would never get past8 percent marketshare. The analyst felt that VMware and Microsoft would be the two dominant players with the bulk of the marketshare.
For cloud computing deployments, the speaker suggested separating "static" VMs from "dynamic" ones. Centralize your external storage first, and implement data deduplicationfor the OS load images. Which x86 workloads are best for server virtualization? The speaker offered this guidance:
The "good" are CPU-bound workloads, small/peaky in nature.
The "bad" are IO-intensive, those that exploit the features of native hardware
The "ugly" refers to workloads based on software with restrictive licenses and those not fully supported on VMs. If you have problems, the software vendor may not help resolve them.
Moving to the Cloud: Transforming the Traditional Data Center
IBM VP Willie Chiu presented the various levels of cloud computing.
Software-as-a-Service (SaaS) provides the software application, operating system and hardware infrastructure, such as SalesForce.com or Google Apps. Either the software meets your needs or it doesn't, but has the advantage that the SaaS provider takes care of all the maintenance.
Platform-as-a-Service (PaaS) provides operating system, perhaps some middleware like database or web application server, and the hardware infrastructure to run it on. The PaaS provider maintains the operating system patches, but you as the client must maintain your own applications. IBM has cloud computing centers deployed in nine different countries across the globe offering PaaS today.
Infrastructure-as-a-Service (IaaS) provides the hardware infrastructure only. The client must maintain and patch the operating system, middleware and software applications. This can be very useful if you have unique requirements.
In one case study, Willie indicated that moving a workload from a traditional data center to the cloud lowered the costs from $3.9 million to $0.6 million, an 84 percent savings!
We've Got a New World in Our View
Robert Rosier, CEO of iTricity, presented their "IaaS" offering. "iTricity" was coined from the concept of "IT as electricity". iTricity is the largest Cloud Computing company in continental Europe, hosting 2500 servers with 500TB of disk storage across three locations in the Netherlands and Germany.
Those attendees I talked to that were at this conference before commented that this year's focus on virtualization and cloud computing is noticeably more than in previous years. For more on this, read this 12-page whitepaper:[IBM Perspective on Cloud Computing]
Continuing this week's coverage of the 27th annual [Data Center Conference] I attended some break-out sessions on the "storage" track.
Effectively Deploying Disruptive Storage Architectures and Technologies
Two analysts co-presented this session. In this case, the speakers are using the term "disruptive" in the [positive sense] of the word, as originally used by Clayton Christensen in hisbook[The Innovator's Dilemma], andnot in the negative sense of IT system outages. By a show of hands,they asked if anyone had more storage than they needed. No hands went up.
The session focused on the benefits versus risks of new storage architectures, and which vendors they felt would succeed in this new marketplace around the years 2012-2013.
By electronic survey, here were the number of storage vendors deployed by members of the audience:
14 percent - one vendor
33 percent - two vendors, often called a "dual vendor" strategy
24 percent - three vendors
29 percent - four or more storage vendors
For those who have deployed a storage area network (SAN), 84 percent also have NAS, 61 percent also have some form or archive storage such as IBM System Storage DR550, and 18 percent also have a virtual tape library (VTL).
The speaker credited IBM's leadership in the now popular "storage server" movement to the IBM Versatile Storage Server [VSS] from the 1990s, the predecessor to IBM's popular Enterprise Storage Server (ESS). A "storage server" is merely a disk or tape system built using off-the-shelf server technology, rather than customized [ASIC] chips, lowering thebarriers of entry to a slew of small start-up firms entering the IT storage market, and leading to newinnovation.
How can a system designed for now single point of failure (SPOF) actually then fail? The speaker convenientlyignored the two most obvious answers (multiple failures, microcode error) and focused instead on mis-configuration. She felt part of the blame falls on IT staff not having adequate skills to deal with the complexities of today's storage devices, and the other part of the blame falls on storage vendors for making such complicated devices in the first place.
Scale-out architectures, such as IBM XIV and EMC Atmos, represent a departure from traditional "Scale-up" monolithic equipment. Whereas scale-up machines are traditionally limited in scalability from their packaging, scale-out are limited only by the software architecture and back-end interconnect.
To go with cloud computing, the analyst categorized storage into four groups: Outsourced, Hosted, Cloud, and Sky Drive. The difference depended on where servers, storage and support personnel were located.
How long are you willing to wait for your preferred storage vendor to provide a new feature before switching to another vendor? A shocking 51 percent said at most 12 months! 34 percent would be willing to wait up to 24 months, and only 7 percent were unwilling to change vendors. The results indicate more confidence in being able to change vendors, rather than pressures from upper management to meet budget or functional requirements.
Beyond the seven major storage vendors, there are now dozens of smaller emerging or privately-held start-ups now offering new storage devices. How willing were the members of the audience to do business with these? 21 percent already have devices installed from them, 16 percent plan to in the next 12-24 months, and 63 percent have no plans at all.
The key value proposition from the new storage architectures were ease-of-use and lower total cost of ownership.The speaker recommended developing a strategy or "road map" for deploying new storage architectures, with focus on quantifying the benefits and savings. Ask the new vendor for references, local support, and an acceptance test or "proof-of-concept" to try out the new system. Also, consider the impact to existing Disaster Recovery or other IT processes that this new storage architecture may impact.
Tame the Information Explosion with IBM Information Infrastructure
Susan Blocher, IBM VP of marketing for System Storage, presented this vendor-sponsored session, covering theIBM Information Infrastructure part of IBM's New Enterprise Data Center vision. This was followed by BradHeaton, Senior Systems Admin from ProQuest, who gave his "User Experience" of the IBM TS7650G ProtecTIER virtual tape library and its state-of-the-art inline data deduplication capability.
Best Practices for Managing Data Growth and Reducing Storage Costs
The analyst explained why everyone should be looking at deploying a formal "data archiving" scheme. Not just for "mandatory preservation" resulting from government or industry regulations, but also the benefits of "optional preservation" to help corporations and individual employees be more productive and effective.
Before there were only two tiers of storage, expensive disk and inexpensive tape. Now, with the advent of slower less-expensive SATA disks, including storage systems that emulate virtual tape libraries, and others that offer Non-Erasable, Non-Rewriteable (NENR) protection, IT administrators now have a middle ground to keep their archive data.
New software innovation supports better data management. The speaker recalled when "storage management" was equated to "backup" only, and now includes all aspects of management, including HSM migration, compliance archive, and long term data preservation. I had a smile on my face--IBM has used "storage management" to refer to these other aspects of storage since the 1980s!
The analyst felt the best tool to control growth is the "Delete" the data no longer needed, but felt that nobody uses Storage Resource Management (SRM) tools needed to make this viable. Until then, people willchose instead to archive emails and user files to less expensive media.The speaker also recommended looking into highly-scalable NAS offerings--such as IBM's Scale-Out File Services (SoFS), Exanet, Permabit, IBRIX, Isilon, and others--when fast access to files is worth the premium price over tape media.The speaker also made the distinction between "stub-based" archiving--such as IBM TSM Space Manager, Sun's SAM-FS, and EMC DiskXtender--from "stub-less" archive accomplished through file virtualization that employes a global namespace--such as IBM Virtual File Manager (VFM), EMC RAINfinity or F5's ARX.
She made the distinction between archives and backups. If you are keeping backups longer than four weeks, they are not really backups, are they? These are really archives, but not as effective. Recent legal precedent no longer considers long-term backup tapes as valid archive tapes.
To deploy a new archive strategy, create a formal position of "e-archivist", chose the applications that will be archived and focus on requirements first, rather than going out and buying compliance storage devices. Try to get users to pool their project data into one location, to make archiving easier. Try to have the storage admins offer a "menu" of options to Line-of-Business/Legal/Compliance teams that may not be familiar with subtle differences in storage technologies.
While I am familiar with many of these best practices already, I found it useful to see which competitiveproducts line up with those we have already within IBM, and which new storage architectures others find mostpromising.
Well, it's Wednesday, day three at the [Data Center Conference] here in Las Vegas, Nevada. Unlike other conferencesthat concentrate all of their keynote sessions at the front of the agenda,this conference spread them out over several days. They had three on Tuesday, two more Wednesday, and the last one on Thursday. Here are my thoughts on the two keynote sessions on Wednesday.
Top 10 Disruptive Technologies affecting the Data Center
The analyst presented his "top ten" technologies to watch:
Storage Virtualization - I was glad this made top of the list!
Cloud Computing - IBM was recognized for its leadership in this space. Cloud computing brings together new models of acquisition, billing, access, and deployment of new technology.
Servers: Beyond Blades - Currently, distributed servers have fixed CPU, memory and I/O capability, as manufactured at the factory, but what if you can re-assign these resources dynamically? New technologies mightmake this possible.
Virtualization for desktops - not just hosted virtual desktops, the speaker proposed having"portable personalities" that an employee might carry around on a CDrom or USB memory stick, andthen use whatever computer equipment was nearby.
Enterprise Mashups - You know analysts have too much time on their hands when they come up withtheir own eight-layer reference architecture for enterprise adoption of Web 2.0 technologies.
Specialized Systems - These are sometimes called heterogeneous systems, hybrids, or application-specific appliances. Unlike general purposes servers, these are more difficult to re-purpose as your needs change. However, if done right, can provide better performance for specific workloads.
Social Software and Social Networking - A survey of the audience found 18 percent were alreadyusing Mashups in the enterprise, but 65 percent haven't looked at this at all. Because traditionalhierarchically-organized companies can't re-structure their employees fast enough, the use ofsocial software to develop "virtual teams" and "communities of interest" can be an effective wayto get the "wisdom of crowds" from your employees. Rather than just installing this kind of software, the speaker felt it was better to just "plant seeds" and let social networks grow withinthe enterprise.
Unified Communications - Do you use different providers or software for cell phone, land line, wi-fi, internet, Instant Messaging (IM), audio conferencing, video conferencing, and email? The promise of Unified Communications is to bring this all together.
Zones and Pods - In the 1990s, traditional design for data centers tried to anticipate growthover the next 15-20 years, and build accordingly. These did not foresee all the changes in IT.The new best practice is a "pod approach" where you only build what you need for the next 5 to 7years, with the architecture to expand as needed. A traditional 9000-square-foot data center thatsupports 150 "watts-per-square-foot" would cost over $20 million to build, and over $1 million inelectricity every year. A pod alternative might cost less than $12 million to build, and nearlycut electricity costs in half.
Green IT - rapid "green" improvements are being demanded on IT operations, not just forpolitical correctness, but also for cost savings. A survey of the audience found 7 percentwilling to pay a premium price for green solutions, and another 26 percent willing to pay aslightly higher price for green features and attributes.
Don McMillan, Computer Engineer turned Stand Up Comic
Don gave a hilarious look at the IT industry. While most comics that are often hired to entertainthe audience have only a layman's knowledge of what we do, Don has a masters degree in ElectricalEngineering from Stanford and worked at a variety of IT companies, including AT&T Bell Labs andVLSI Technology. You can see more of his bio on his[Technically Funny] Web site.
Here's Don in a [four-minute video] demonstrating the kind of observational humor he performs.
It's good to see a bit of humor at IT conferences. With the pressures of IT staff and managementto manage explosive growth with shrinking budgets, the attendees appreciated the mix of serious with the not-so-serious.
The title of this post is inspired by Baxter Black's [latest book]. Rathera recap of the break-out sessions, I thought I would comment on a fewsentences, phrases or comments I heard in the afternoon and evening.
Stop buying storage from EMC or NetApp
The lunch was sponsored by Symantec. Rod Soderbery presented "Taking the cost out ofcost savings", explaining some ideas to reduce IT costs immediately.
First, he suggested to "stop buying storage" from EMC or NetApp that charge a premiumfor tier-one products. Instead, Rod suggested that people should "think like a Web company"and buy only storage products based on commodity hardware to save money, and to use SRM software to identify areas of poor storage utilization. IBM's TotalStorage Productivity Center softwareis often used to help with this analysis.
His other suggestions were to adopt thin provisioning, data deduplication, and virtualization.The discussion at my table started with someone asking, "How do we adopt those functions without buying new storage capacity with those features already built-in?" I explained that IBM's SAN Volume Controller (SVC),N series gateways, and TS7650G ProtecTIER virtual tape gateway can all provide one or moreof these features to your existing disk storage capacity.
IBM and HP are leaders in blade servers
In the session "Future of Server and OS: Disappearing Boundaries", the audience confirmedby electronic survey that IBM and HP are the leaders in blade servers, although blades representonly 8-10 percent of the overall server market.
Interestingly, 22 percent of the audience has deployed both x86 and non-x86 (POWER, SPARC, etc.) blade servers.The presenters considered this an interesting insight.
Another survey of the audience found that 3 percent considered Sun/STK as their primary storagevendor. One of the presenters was delighted that Sun is still hanging in there.
IBM Business Partners deliver the best of IBM and mask the worst
Elaine Lennox, IBM VP, and Mark Wyllie, CEO of Flagship Solutions Group, Inc. presentedIBM-sponsored back to back sessions. Elaine presented IBM's vision, the New Enterprise Data Center, and the challenges that demand a smarter planet.
Mark focused on his company's experience working with IBM through Innovation Workshops. Theseare assessments that can help someone identify where you are now, where you want to be, andthen action plans to address the gaps.
Cats and Dogs, Oil and Water, Microsoft Windows and Mission-critical applications, what do all of these have in common?
NEC Corporation of America sponsored some sessions on some x86-based solutions they have to offer.The first part, titled "Rats Nests, Snow Drifts and Trailers" focused unified storage, andthe second part, presented by Michael Nixon, focused on how to bring Microsoft Windows servers into the data center for mission-critical applications.
The Economy might be slowing, but storage is still growing
Two analysts co-presented "The Enterprise Storage Scenario". Unlike computing capacity, thereis no on/off switch for storage, not from applications nor from end-users. The cost ofpower for storage is expected to be 3x by 2013. Virtual servers, includingVMware and Microsoft's Hyper-V will drive the need for shared external disk storage.A survey of the audience found 20 percent were expecting to purchase additional storagecapacity 4Q08.
When someone reaches age 52, they expect to coast the rest of their career
At dinner with analysts, the discussion of financial meltdown and bailouts is unavoidable,including everyone's views about the proposed bailout of the Big 3 automakers. I can'tdefend Ford, GM and Chrysler paying their people $70 US dollars per hour, when their UScounterparts at Toyota or Honda are only paid $45 to $50 dollars per hour.
However, I have a close friend who retired after 20 years working for the fire department,and a cousin who retired after 20 years serving in the Navy (the US Navy, not the BolivianNavy), and both are still in their forties in age. A long time ago, IT professionalsretired after 30 years, in some cases with 50 to 60 percent of their base pay as theirpension for the rest of their lives. A 52-year-old that has worked 30 years might expect to enjoy the rest of his old age playing golf and pursuing other hobbies. This is not "coasting", it is called "retirement". The few of my colleagues that I have seen who worked 35 to 40 years did so becausethey enjoyed the challenge of work at IBM. They enjoyed solving tough engineering problems and helping customers.As long as they were having fun on the job,IBM was glad to keep their wealth of experience on board and actively engaged.
Unfortunately, many people rely on their own investments in the stock market for retirement, ratherthan company pensions. With the current financial crisis, I suspect many people my age arereconsidering their previous retirement plans.
We're going to need more trains!
I took the monorail back to my hotel. The ride includes funny announcements and statistics,including this gem:
"Since 1940, Las Vegas has doubled in population every ten years, which means thatby the year 2230, we will have over 1 trillion people calling Las Vegas home. We're goingto need more trains!"
That wraps up Tuesday, Day 2 of my attendance here! Now for some sleep.
I did not register soon enough to get into the MGM Grand itself, so I am staying at a Hiltonat the other end of the Las Vegas strip, but am able to hop on the "Monorail" to get to the MGM,just in time for the breakfast and first welcome session.
This conference has a familiar set up: six keynote sessions, 62 break-out sessions, and fourtown hall meetings. Thanks to electronic survey devices on the seats, speakers were able to gatherreal-time demographics. A large portion of attendees, including myself, are attending this conference for theirfirst time. Here's my recap of the first three keynote sessions:
The Future of Infrastructure and Operations: The Engine of Cloud Computing
How much do companies spend just to keep current? As much as 70 percent! The speaker noted thatthe best companies can get this down to 10 to 30 percent, leaving the rest of the IT budget to facilitate transformation. He predicts that companies are transforming their data centers fromsprawled servers to virtualization, towards a fully automated, service-oriented, real-time infrastructure.
Whereas the original motivation for IT virtualization was to reduce costs, companies now recognizethat they greatly improve agility, the ability to rapidly provision resources for new workloads, and that this will then lead to opportunites for alternative sourcing, such as cloud computing.
The operating system is becoming commoditized, focusing attention instead to a new concept: the"Meta OS". VMware's Virtual Data Center and Microsoft's Azure Fabric Controller are just two examples.Currently, analysts estimate only about 12 percent of x86 workloads are running virtualized, but thatthis could be over 50 percent by 2012.In this same time frame, year 2012, storage Terabytes is expected to increase 6.5x fold, and WAN bandwidthgrowing 35 percent per year.
Virtualization is not just for business applications. There are opportunities to eliminate the mostcostly part of any business: the Personal Computer, poster child of the skyrocketing costs of the client/server movement. Remote hosting of applications, streaming of applications,software as a service (SaaS) and virtual machines for the desktop can greatly reduce costs of customizedPC images and help desk support.
Cloud computing not only reduces per costs per use, but provides a lower barrier of entry and somemuch needed elasticity.Draw a line anywhere along the application-to-hardware software/hardware stack, and you can define acloud computing platform/service. About 65 percent of the attendees surveyed indicated that they were already doing something with CloudComputing, or were planning to in the next four years.
To help get there, the speaker felt that Value-added Resellers (VAR) and System Integrators (SI) wouldevolve into "service brokers", providing Small and Medium sized Businesses (SMB) "one throat to choke" in mixedmultisourced operations. The term "multisource" caught me a bit off-guard, referring to having someworkloads run internally (insourced) while other workloads run out on the Cloud (outsourced). Largerenterprises might have a "Dynamic Sourcing Team", a set of key employees serving as decision makers, employing both business and IT skills to determine the best sourcing for each application workload.
What are the biggest obstacles to getting there? The speaker felt it was the IT staff. People and cultureare the most difficult to change. The second are lack of appropriate metrics. Here were the survey resultsof the attendees:
41 percent had metrics for infrastructure economic attributes
49 percent had metrics for qualities of service (QoS)
12 percent had metrics to measure agility, speed of resource provisioning
The Data Center Scenario: Planning for the Future
This second keynote had two analyst "co-presenters". The focus was on the importance of having a documented Data Center strategy and architecture. Unfortunately, most Data Centers "happen on their own", with a majoroverhaul every 5 to 10 years. The speakers presented some "best practices" for driving this effort.
The first issue was to identify tiers of criticality, similar to those by the[Uptime Institute]. In their example, the most criticalworkloads would have perhaps recovery point objectives (RPO) of zero, and recover time objectives of lessthan 15 minutes. This is achievable using synchronous mirroring with fully automation to handle the failover.
The second issue was to recognize that many applications were designed for local area networks (LAN), butmany companies have distributed processing over a wide area network (WAN). Latency over these longer distancescan kill distributed performance of these applications.
The third issue was that different countries offer different levels of security, privacy and law enforcement.Canada and Ireland, for example, had the lowest risk, countries like India had medium risk, and countries likeChina and Russia had the highest risk, based on these factors.
The speakers suggested the following best practices:
Get a better understanding of the costs involved in providing IT services
Centralize applications that are not affected by latency, but regionalize those that are affected toremote locations to minimize distance delays.
Work towards a "lights out" data center facility, with operations personnel physically separated fromdata center facilities.
For the unfortunate few that are trying to stretch out more life from their existing aging data centers,the speakers offered this advice:
Build only what you need
Decommission orphaned servers and storage, which can be 1 to 12 percent of your operations
Target for replacement any hardware over five years old, not just to reduce maintenance costs, butalso to get more energy-efficient equipment.
Consider moving test workloads, and as much as half of your web servers, off UPS and onto the nativeelectricity grid. In the event of an outage, this reduces UPS consumption.
Implement power-capping and load-shedding, especially during peak times.
Enacting these changes can significantly improve the bottom line. Archaic data centers, those typically over 10 years old with power usage effectiveness (PUE) over 3.0 can cost over twice as much as a moreefficient data center. To learn more about PUE as a metric, see the Green Grid's whitepaper[Data Center power efficiency metrics:PUE and DCiE].
While virtualization can help with these issues, it also introduces new problems, such as VM sprawl anddealing with antiquated licensing schemes of software companies.
The Four Traits of the World's Best-Performing Business Leaders
Best-selling author Jason Jennings presented his findings in researching his various books:
It's Not the Big That Eat the Small... It's the Fast That Eat the Slow : How to Use Speed as a Competitive Tool in Business
Less Is More : How Great Companies Use Productivity As a Competitive Tool in Business
Think Big, Act Small
Hit the Ground Running : A Manual for New Leaders
Jason identified the best companies and interviewed their leaders, including such companies as Koch Industries, Nucor Steel, and IKEA furniture. The leaders he interviewed felt a calling to serveas stewards of their companies, not just write mission and vision statements, and be willingto let go of projects or people that aren't working out.
Jasonindicated a 2007 Gallup poll on the American workplace indicates that 70 percent of employees do notfeel engaged in their jobs.The focus of these leaders isto hire people with the right attitudes, rather than the right aptitudes, and give those people with the knowledge and the right to make business decisions. If done well,employees will think and act as owners, and hold themselves accountable for their economic results. Jason found cases where 25-year-olds were givenresponsibility to make billion-dollar decisions!
I found his talk inspiring! The audience felt motivated to do their jobs better, and be more engagedin the success of their companies.
These keynote sessions set the mood for the rest of the week. I can tell already that the speakers willtoss out a large salad of buzzwords and IT industry acronyms. I saw several people in the audience confusedon some of the terminology, and hopefully they will come over to IBM booth 20 at the Solutions Expofor straight talk and explanation.
I helped set up the IBM booth at the Solutions Center, third floor, where we will have variousproducts on display, as well as subject matter experts to handle all the questions.
I also went ahead and got my conference badge. While most of my cohorts have purple badges, limiting them to the Solution Centers area, I have a red badge, so that I can attend the variouskeynote and break-out sessions this week.
In keeping with our "green" theme, we have all been given matching light green shirts, and these are 70 percent Bamboo cloth, and 30 percent cotton. They are very comfortable,and sustainable! If you see me, come up and just feel my shirt, go ahead, I won't mind!
Tomorrow, the fun begins with the keynote speakers!
Wrapping up this week's theme of thankfulness, I am thankful for theOne Laptop Per Child [OLPC] and their Get-One-Give-One (G1G1)offer.
Last November, I was one of the first to [sign up for the G1G1],and when mine arrived December 24, I posted initial observations in this[OLPC series].Over the past year, I have had the pleasure of helping out teams in Nepal and Uruguay,collaborating with developers in France, India and the United States. Giving back to othershas been a richly rewarding experience for me. I made some new friends, built up newprofessional contacts, and learned some new tricks as well.
Last year's G1G1 offer was limited to US and Canada, but this year, the OLPC have enlisted [Amazon.com] and made the offer available worldwide. You can choose to either give a single laptop for $199 USD, or get two laptops, get one for yourself or your family, and give the other to someone like Zimi, for $399 USD.
I'm thankful I did. Happy Thanksgiving to all my readers in the USA!
During the Republican primaries, Mitt Romney promised Michigan he wouldbring back all those jobs back to the Auto Industry, while his opponent,John McCain, told the audience that those jobs are gone forever, time tostart learning new skills. Mitt won the state, but lost the nomination,and perhaps this snapped him back to reality. Mitt now has a new prescription for what ails the US Auto industry--straight talk that he should have been saying during his campaign,telling people what they should hear, rather than what they wanted to hear.
Gaurav takes this argument one step further, referring to IBM's amazingturn-around back in 1993. Whereas the US Auto Industry has pushed backagainst inevitable globalization, IBM has embraced it, re-inventing itself into aGlobally Integrated Enterprise [GIE] and helping our clients do the same.I've been working for IBM since 1986, so I remember the pre-1993 IBM and how different it is now in the post-1993 era.
The marketplace has responded positively. Since 2004, more than 5,000 companies worldwide have replaced their HP, Sun, and EMC products with energy-efficient IBM Systems: Servers and Storage. Companies have invested in IBM's servers and storage to tackle their most challenging business objectives and to help reduce sprawling data center costs for labor, energy and real estate.This announcement was part of IBM's[Press Release]for its Migration Factory offering. The Migration Factory includes competitive server assessments, migration services, and other resources to help customers achieve energy and space savings and lower their cost of ownership.
Earlier this month, IBM's Chairman and CEO Sam Palmisano recently outlined the possibilities of a smarter planet to the Council on Foreign Relations.Steve Lohr of the New York Times weighs in with his article [I.B.M. Has Tech Answer for Woes of Economy], and Dr. Fern Halper of Hurwitz & Associates gives her take over at [IT-Director.com].
Transcontinental flights and the[Travel Channel] have made the world smaller.Thomas Friedman argued the world has also become "flatter",thanks to advances in computers and global communication, in his 2005 book[The World is Flat].Now, IBM recognizes that InformationTechnology (I.T.) can help us solve the financial meltdown, global warming, and other major problems the world is now faced with.
How? First, our world is becoming instrumented. Sensors, RFID tags and other equipmentare now inexpensive and readily available to be placed wherever they are needed. Second, our world is becoming more interconnected. We are closely approaching two billion internet users andfour billion mobile subscribers, andthese can connect to the trillions of RFID tags, sensors and other instrumentation. Third,our world needs to get more intelligent. Not just US auto workers learning new skills,but all these instruments providing information that can be acted on with intelligentalgorithms. Algorithms can help with automobile traffic in large cities, enhance energyexploration, or improve healthcare.
This week is Thanksgiving holiday in the USA, so I thought a good theme would be things I am thankful for.
I'll start with saying that I am thankful EMC has finally announcedAtmos last week. This was the "Maui" part of the Hulk/Maui rumors we heard over a year ago. To quickly recap, Atmos is EMC's latest storage offeringfor global-scale storage intended for Web 2.0 and Digital Archive workloads. Atmos can be sold as just software, or combined with Infiniflex,EMC's bulk, high-density commodity disk storage systems. Atmos supports traditionalNFS/CIFS file-level access, as well as SOAP/REST object protocols.
I'm thankful for various reasons, here's a quick list:
It's hard to compete against "vaporware"
Back in the 1990s, IBM was trying to sell its actual disk systems against StorageTek's rumored "Iceberg" project. It took StorageTek some four years to get this project out,but in the meantime, we were comparing actual versus possibility. The main feature iswhat we now call "Thin Provisioning". Ironically, StorageTek's offering was not commercially successful until IBM agreed to resell this as the IBM RAMAC Virtual Array (RVA).
Until last week, nobody knew the full extent of what EMC was going to deliver on the many Hulk/Maui theories. Severalhinted as to what it could have been, and I am glad to see that Atmos falls short of those rumored possibilities. This is not to say that Atmos can't reach its potential, and certainly some of the design is clever, such as offering native SOAP/REST access.
Instead, IBM now can compare Atmos/Infiniflex directly to the features and capabilities of IBM's Scale Out File Services [SoFS], which offers a global-scale multi-site namespace with policy-based data movement, IBM System Storage Multilevel Grid Access Manager[GAM] that manages geographical distrubuted information,and IBM [XIV Storage System] that offers high-density bulk storage.
Web 2.0 and Digital Archive workloads justify new storage architectures
When I presented SoFS and XIV earlier this year, I mentioned they were designed forthe fast-growing Web 2.0 and Digital Archive workloads that were unique enough to justify their own storage architectures. One criticism was that SoFS appeared to duplicate what could be achieved with dozens of IBM N series NAS boxes connected with Virtual File Manager (VFM). Why invent a new offering with a new architecture?
With the Atmos announcement, EMC now agrees with IBM that the Web 2.0 and DigitalArchive workloads represent a unique enough "use case" to justify a new approach.
New offerings for new workloads will not impact existing offerings for existing workloads
I find it amusing that EMC is quickly defending that Atmos will not eat into its DMXbusiness, which is exactly the FUD they threw out about IBM XIV versus DS8000 earlier this year. In reality, neither the DS8000 nor the DMX were used much for Web 2.0 andDigital Archive workloads in the past. Companies like Google, Amazon and others hadto either build their own from piece parts, or use low-cost midrange disk systems.
Rather, the DS8000 and DMX can now focus on the workloads they were designed for,such as database applications on mainframe servers.
Cloud-Oriented Storage (COS)
Just when you thought we had enough terminology already, EMC introduces yet another three-letter acronym [TLA]. Kudos to EMC for coining phrases to help move newconcepts forward.
Now, when an RFP asks for Cloud-oriented storage, I am thankful this phrase will help serve as a trigger for IBM to lead with SoFS and XIV storage offerings.
Digital archives are different than Compliance Archives
EMC was also quick to point out that object-storage Atmos was different from theirobject-storage EMC Centera. The former being for "digital archives" and the latter for"compliance archives". Different workloads, Different use cases, different offerings.
Ever since IBM introduced its [IBM System Storage DR550] several years ago, EMC Centera has been playing catch-up to match IBM'smany features and capabilities. I am thankful the Centera team was probably too busy to incorporate Atmos capabilities, so it was easier to make Atmos a separate offering altogether. This allows the IBM DR550 to continue to compete against Centera's existingfeature set.
Micro-RAID arrays, logical file and object-level replication
I am thankful that one of the Atmos policy-based feature is replicating individualobjects, rather than LUN-based replication and protection. SoFS supports this forlogical files regardless of their LUN placement, GAM supports replication of files and medical images across geographical sites in the grid, and the XIV supports this for 1MBchunks regardless of their hard disk drive placement. The 1MB chunk size was basedon the average object size from established Web 2.0 and DigitalArchive workloads.
I tried to explain the RAID-X capability of the XIV back in January, under muchcriticism that replication should only be done at the LUN level. I amthankful that Marc Farley on StorageRap coined the phrase[Micro-RAID array] to helpmove this new concept further. Now, file-level, object-level and chunk-level replication can be considered mainstream.
Much larger minimum capacity increments
The original XIV in January was 51TB capacity per rack, and this went up to 79TB per rack for the most recent IBM XIV Release 2 model. Several complained that nobody would purchase disk systems at such increments. Certainly, small and medium size businessesmay not consider XIV for that reason.
I am thankful Atmos offers 120TB, 240TB and 360TB sizes. The companies that purchasedisk for Web 2.0 and Digital Archive workloads do purchase disk capacity in these large sizes. Service providers add capacity to the "Cloud" to support many of theirend-clients, and so purchasing disk capacity to rent back out represents revenue generating opportunity.
Renewed attention on SOAP and REST protocols
IBM and Microsoft have been pushing SOA and Web Services for quite some time now.REST, which stands for [Representational State Transfer] allows static and dynamic HTML message passing over standard HTTP.SOAP, which was originally [Simple Object Access Protocol], and then later renamed to "Service Oriented Architecture Protocol", takes this one step further, allowingdifferent applications to send "envelopes" containing messages and data betweenapplications using HTTP, RPC, SMTP and a variety of other underlying protocols.Typically, these messages are simple text surrounded by XML tags, easily stored asfiles, or rows in databases, and served up by SOAP nodes as needed.
It's hard to show leadership until there are followers
IBM's leadership sometimes goes unnoticed until followerscreate "me, too!" offerings or establish similar business strategies. IBM's leadership in Cloud and Grid computing is no exception.Atmos is the latest me-too product offering in this space, trying pretty muchto address the same challenges that SoFS and XIV were designed for.
So, perhaps EMC is thankful that IBM has already paved the way, breaking throughthe ice on their behalf. I am thankful that perhaps I won't have to deal with as much FUD about SoFS, GAM and XIV anymore.
Well, I'm back from my vacation from Bali and Singapore, and am glad to seethat my fellow blogger BarryB [aka Storage Anarchist] also had a chance to take a break to exotic locations.
Next Thursday, in the USA, is [Thanksgiving holiday], so this will give me a chance to catch up on my email and read everyone's blog posts and product announcements.
The following week, December 2-5, I'll be attending the 27th annual [Data Center Conference] at the MGM Grand hotel and casino in Las Vegas, Nevada. IBM is a Premier and Platinum sponsor for this event.Look for me in one of the many break-out sessions, one-on-oneexecutive meetings, or IBM's "booth 20" at the solution center. Our team will be showingoff IBM's XIV, SVC and TotalStorage Productivity Center offerings, aswell as explaining IBM Information Infrastructure and the rest of theNew Enterprise Data Center strategy.
Well it's Tuesday, and ["election day"] here in the USA, and again IBM has more announcements.
IBM announced [IBM Tivoli Key Lifecycle Manager v1.0] (TKLM) to manage encryption keys. This provides a graphical interface to manage encryption keys, including retention criteria when sharing keys with other companies.
TKLM is supported on AIX, Solaris, Windows, Red Hat and SUSE Linux. IBM plans to offer TKLM forz/OS in 2009. TKLM can be used with Firefox or Internet Explorer web browser. This will include the Encryption Key Manager (EKM) that IBM offered initially to support encryption keys for the TS1120, TS1130, and LTO-4 drives.
While this is needed today for tape, IBM positions this software to also manage the encryption keys for "Full Drive Encryption" (FDE) disk drive modules (DDM) in IBM disk systems in 2009.
There's some good discussion in the comments section over at Robin Harris' StorageMojo blog for hispost [Building a 1.8 Exabyte Data Center].To summarize, a student is working on a research archive and asked Robin Harris for his opinion. The archive will consist of 20-40 million files averaging 90 GB in size each, for a total of 1800 PB or 1.8 EB. By comparison, anIBM DS8300 with five frames tops out at 512TB, so it would take nearly 3600 of these to hold 1.8 EB. While this might seem like a ridiculous amount of data, I think the discussion is valid as our world is certainly headed in that direction.
IBM works with a lot of research firms, and the solution is to put most of this data on tape, with just enough disk for specific analysis. Robin mentions a configurion with Sun Fire 4540 disk systems (aka Thumper). Despite Sun Microsystems' recent [$1.7 Billion dollar quarterly loss], I think even the experts at Sun would recommend a blended disk-and-tape solution for this situation.
Take for example IBM's Scale Out File Services [SoFS] which today handles 2-3 billion files in a single global file system, so 20-40 million would present no problem. SoFS supports a mix of disk and tape, with built-in movement, so that files that were referenced would automatically be moved to disk when needed, and moved back to tape when no longer required, based on policies set by the administrator. Depending on the analysis, you may only need 1 PB or less of disk to perform the work, which can easily be accomplished with a handful of disk systems, such as IBM DS8300 or IBM XIV, for example.
The rest would be on tape. Let's consider using the IBM TS3500 with [S24 High Density] frames. A singleTS3500 tape library with fifteen of these HD frames could hold 45PB of data, assuming 3:1 compression on 1TB-size 3592 cartridges. You wouldneed 40 (forty) of these libraries to get to the full 1800 PB required, and these could hold even more as higher capacity cartridges are developed. IBM has customers with over 40 tape libraries today (not all with these HD frames, of course), but the dimensions and scale that IBM is capable lies within this scope.
(For LTO fans, fifteen S54 frames would hold 32PB of data, assuming 2:1 compression on 800GB-size LTO-4 cartridges.so you would need 57 libraries instead of 40 in the above example.)
This blended disk-and-tape approach would drastically reduce the floorspace and electricity requirements when compared against all-disk configurations discussed in the post.
People are rediscovering tape in a whole new light. ComputerWorld recently came out with an 11-page Technology Brief titled [The Business Value of Tape Storage],sponsored by Dell. (Note: While Dell is a competitor to IBM for some aspects of their business, they OEM their tape storage systems from IBM, so in that respect, I can refer to them as a technology partner.) Here are some excerpts from the ComputerWorld brief:
For IT managers, the question isnot whether to use tape, but whereand how to best use tape as part of acomprehensive, tiered storage architecture.In the modern storage architecture,tape plays a role not onlyin data backup, but also in long-termarchiving and compliance.
“Long-term archiving is the primaryreason any company shoulduse tape these days,” says MikeKarp, senior analyst at EnterpriseManagement Associates in Boulder,Colo. Companies are increasinglylikely to use disk in conjunctionwith tape for backup, but for long-termarchiving needs, tape remainsunbeatable.
After factoring inacquisition costs of equipment andmedia, as well as electricity and datacenter floor space, Clipper Groupfound that the total cost of archivingsolutions based on SATA disk, theleast expensive disk, was up to 23times more expensive than archivingsolutions involving tape. Calculatingenergy costs for the competing approaches,the costs for disk jumpedto 290 times that of tape.
“Tape isalways the winner anywhere costtrumps anything else,” says Karp.No matter how the cost is figured,tape is less expensive.
Beyond IT familiarity with tape,analysts point to other reasons whyorganizations will likely keep tapein their IT storage infrastructures.Energy savings, for example, is themost recent reason to stick withtape. “The economics of tape arepretty compelling, especially whenyou figure in the cost of power,”Schulz says.
So, whether you are planning for an Exabyte-scale data center, or merely questioning the logic of a disk-for-everything storage approach, you might want to consider tape. It's "green" for the environment, and less expensive on your budget.
Perhaps the recent financial meltdown is making storage vendors nervous.Both IBM and EMC gained market share in 3Q08, but EMC is acting strangelyat IBM's latest series of plays and announcements. Almost contradictory!
Benchmarks bad, rely on your own in-house evaluations instead
Let's start with fellow blogger Barry Burke from EMC, who offers his latest post[Benchmarketing Badly] with commentaryabout Enterprise Strategy Group's [DS5300 Lab Validation Report]. The IBM System Storage DS5300 is one of IBM's latest midrange disk systems recently announced. Take for example this excerpt from BarryB's blog post:
"I was pleasantly surprised to learn that both IBM and ESG agree with me about the relevance and importance of the Storage Performance Council benchmarks.
That is, SPC's are a meaningless tool by which to measure or compare enterprise storage arrays."
Nowhere in the ESG report says this, nor have I found any public statements from either IBM nor ESG that makes this claim. Instead, the ESG report explains that traditional benchmarks from the Storage Performance Council [SPC] focus on a single, specific workload, and ESG has chosen to complement this with a variety of other benchmarks to perform their product validation, including VMware's "VMmark", Oracle's Orion Utility, and Microsoft's JetStress.
Benchmarks provide prospective clients additional information to make purchasedecisions. IBM understands this, ESG understands this, and other well-respected companies like VMware, Oracle and Microsoft understand this. EMC is afraid that benchmarks mightencourage a client to "mistakenly" purchase a faster IBM product than a slower EMC product. Sunshine makes a great disinfectant, but EMC (and vampires) prefer their respective "prospects" remain in the dark.
Perhaps stranger still is BarryB's postscript. Here's an excerpt:
"... a customer here asked me if EMC would be willing to participate in an initiative to get multiple storage vendors to collaborate on truly representative real-world "enterprise-class" benchmarks, and I reassured him that I would personally sponsor active and objective participation in such an effort - IF he could get the others to join in with similar intent."
As I understand it, EMC was once part of the Storage Performance Council a long time ago, then chose to drop out of it. Why re-invent the wheel by creating yet another storage industry benchmark group? EMC is welcome to come back to SPC anytime! In addition to the SCP-1 and SPC-2 workloads, there is work underway for an SPC-3 benchmark. Each SPC workload provides additional insight for product comparisons to help with purchase decisions. If EMC can suggest an SPC-4 benchmark that it feels is more representative of real-world conditions, they are welcome to join the SPC party and make that a reality.
The old adage applies: ["It's better to light a candle than curse the darkness"]. EMC has been cursing the lack of what it considers to be acceptable benchmarks but has yet to offer anything more realistic or representative than SPC.What does EMC suggest you do instead? Get an evaluation box and run your own workloads and see for yourself! EMC has in the past offered evaluation units specifically for this purpose.
In-house evaluations bad, it's a trap!
Certainly, if you have the time and staff to run your own evaluation, with your own applications in your own environment, then I agree with EMC that this can provide better insight for your particular situation than standardized benchmarks.
In fact, that is exactly what IBM is doing for IBM XIV storage units, which are designed for Web 2.0 and Digital Archive workloads that current SPC benchmarks don't focus on. Fellow blogger Chuck Hollis from EMC opines in his post[Get yer free XIV!]. Here's an excerpt:
"Now that I think about it, this could get ugly. Imagine a customer who puts one on the floor to evaluate it, and -- in a moment of desperation or inattention -- puts production data on the device.
Nobody was paying attention, and there you are. Now IBM comes calling for their box back, and you've got a choice as to whether to go ahead and sign the P.O., or migrate all your data off the thing. Maybe they'll sell you an SVC to do this?
Yuck. I bet that happens more than once. And I can't believe that IBM (or the folks at XIV) aren't aware of this potentially happening."
Perhaps Chuck is speaking from experience here, as this may have happened with customers with EMC evaluation boxes, and is afraid this could happen with IBM XIV. I don't see anything unique about IBM XIV in the above concern. Typical evaluations involve copying test data onto the box, test it out with some particular application or workload, and then delete the data no longer required. Repeat as needed. Moving data off an IBM XIV is aseasy as moving data off an EMC DMX, EMC CLARiiON or EMC Celerra, and I am sure IBM wouldgladly demonstrate this on any EMC gear you now have.
Thanks to its clever RAID-X implementation, losing data on an IBM XIV is less likely thanlosing data on any RAID-5 based disk array from any storage vendor. Of course, there will always be skeptics about new technology that will want to try the box out for themselves.
If EMC thought the IBM XIV had nothing unique to offer, that its performance was just "OK",and is not as easy to manage as IBM says it is, then you would think EMC would gladly encourage such evaluations and comparisons, right?
No, I think EMC is afraid that companies will discover what they already know, that IBM has quality products that would stand a fair chance of side-by-side comparisons with their own offerings.We have enough fear, uncertainty and doubt from our current meltdown of the global financial markets, don't let EMC add any more.
Have a safe and fun Halloween! If you need to add some light to your otherwise dark surroundings, consider some of these ideas for [Jack-O-Lanterns]!
This is page 34 of Sequoia Capital's[56-slide presentation] about the current financial meltdown. In the past, IT spending tracked closely to the rest of the economy, but the latest downturn has not yet reflected in IT spend.
The rest of the deck is worth going through, with interesting stats presented in a clear manner.
Well, it's Tuesday again, and that means more IBM announcements!
Storage Area Network (SAN)
IBM and Cisco announced [three new blades] for the Cisco MDS 9500 seriesdirectors: 24-port 8 Gbps, 48-port 8 Gbps, and 4/44 blended. The 4/44blended has 4 of the faster 8 Gbps ports, and 44 of the 4 Gpbs ports,so that you can auto-negotiate down to 1 Gbps for your older gear, andstill take advantage of the faster 8 Gbps speeds during the transition.
On the Brocade side, IBM announced the newIBM System Storage Data Center Fabric Manager [DCFM] V10 software. This replaces the products formerly known as BrocadeFabric Manager and McData Enterprise Fabric Connection Manager (EFCM).This software can support up to 24 distinct fabrics, up to 9000 ports,including a mix of FCP, FICON, FCIP and iSCSI protocols.
(On a related note, I heard that Microsoft is planning to rename "Windows Vista" to "Windows 7" next year! Like we say here in Tucson,if it ends in "-ista" it is going to fail in the marketplace! Perhaps EMC should rename their storage virtualization product to "In-7"?).
IBM System Storage DR550
IBM announced today that it now supports [RAID 6 onthe DR550] compliance and retention storage system.
There are a few RAID-5 based EMC Centera customers out there who have notyet switched over to the IBM DR550, and now this might be just the littlenudge they need. For long-term retention of regulatory compliance data,RAID-5 doesn't cut it, you need an advanced RAID scheme, such as RAID-6, RAID-DP or RAID-X.
The DR550 provides non-erasable, non-rewriteable (NENR) storage supportto keep retention-managed data on disk and tape media. It supports 1 TBSATA disk drives and 1TB tape cartridges to provide high capacity at lowcost and "green" low energy consumption.
IBM System Storage N series
Several of our disk systems got improved and enhanced. Let's start withthe IBM System Storage N series[hardware and software] enhancements. IBM now offers high-speed 450GB 15K RPM drives. These are Fibre Channel (FC) drives for the EXN4000 expansion drawers, and Serial Attached SCSI (SAS) drives for the entry-levelN3300 and N3600 models.
The "gateway" models now support a variety of functions that were formerlyonly available on the appliance models. This includes Advanced Single Instance Storage (A-SIS), Disk Sanitization, and FlexScale.
A-SIS is IBM's "other" deduplication function, and I talked about this in my post [A-SIS Storage Savings Estimator Tool]. Disk Sanitization will physicallywrite ones and zeros over existing data to eliminate it, what IBM sometimes calls "Data Shredding".
The last feature, FlexScale, might be new for many. It is software toenable to use of the "Performance Accelerator Module" (PAM). The PAM isa PCI-Express card with 16GB on-board RAM that acts as a secondary cachebehind main memory of the N series controller. Depending on the model,you can have one to five of these cards fit into the controller itself,boosting random read performance, metadata access, and write block destage.
IBM System Storage DS5000
IBM's latest entry into the DS family has been hugely successful.In addition to Linux, Windows and AIX, the DS5000 now supports [Novell Netware and Sun Solaris] operating systems.
For infrastructure management, IBM has enhanced the Remote Support Manager [RSM]that supports DS3000 and DS4000 has been extended to support DS5000 as well. This software can monitor up to 50 disk systems, will e-mail alerts to IBM when something goes wrong, and allow IBM to dial in via modem to get more diagnostic information to improve service to the client. Also, the IBM System Storage Productivity Center [SSPC]which now supports the DS8000 and SAN Volume Controller (SVC) has been extended to also support the DS5000.
IBM XIV Storage System
