In his blog post, [The Lure of Kit-Cars], fellow blogger Chuck Hollis (EMC) uses an excellent analogy delineating the differences between kit-cars you build from parts, versus fully-integrated systems that you can drive off the car dealership showroom lot. The analogy holds relatively well, as IT departments can also build their infrastructure from parts, or you can get fully-integrated systems from a variety of vendors.
Is this what your data center looks like?
Certainly, this debate is not new. In my now infamous 2007 post [Supermarkets and Specialty Shops], I explained that there were clients that preferred to get their infrastructure from a single IT supermarket, like IBM or HP, while others were lured into thinking that buying separate parts from butchers, bakers and candlestick makers and other specialty shops was somehow a better idea.
Chuck correctly explains that in the early years of the automobile industry, before major car manufacturers had mass-production assembly lines, putting a car together from parts was the only way cars were made. Today, only the few most avid enthusiasts build cars this way. The majority get cars from a single seller and drive away. In my post [Resolving the Identity Crisis], I postulated that EMC appeared to be trying to shed itself of the "disk-only specialty shop" image and over to be more like IBM. Not quite a full IT Supermarket, but perhaps more like a [Trader Joe's] premium-priced retailer.
(If you find that EMC's focus on integrated systems appears to be a 180-degree about-face from their historical focus on selling individual best-of-breed products, see my previous discussion of Chuck's contradictions in my blog post: [Is Storage the Next Confusopoly].)
While companies like EMC might be making this transition, there is a lot of resistance and inertia from the customer marketplace. I agree with Chuck, companies should not be building kit-cars or IT infrastructures from parts, certainly not from parts sold from different vendors. In my post [Talking about Solutions not Products], I explained how difficult it was to change behavior. CIOs, IT directors and managers need to think differently about their infrastructure. Let's take a quick look at some choices:
Following Chuck's argument, it makes no sense to build a "kit-car" combining Oracle/Sun servers with EMC storage. Oracle would argue it makes more sense to run on integrated systems, business logic on their "Exalogic" system, and database processing on their "Exadata". Benchmark after benchmark, however, IBM is able to demonstrate that Oracle applications and databases run faster on IBM systems. Customers that want to run Oracle applications can run either on a full Oracle stack, or a full IBM stack, and both do better than a kit-car including EMC parts.
HP has been working hard to keep up with IBM in this area. With their their partnership with Microsoft, and acquisitions of EDS, 3Com and 3PAR, they can certainly make a case for getting a full HP stack rather than a kit-car mixing HP servers with EMC disk storage. The problem is that HP is focused on a converged infrastructure for private cloud computing, but Microsoft is focused on Azure and public cloud computing. It will be interesting when these two big companies sort this out. Definitely watch this space.
If you squint your eyes and focus on the part of the world that only has x86 machines, then Dell can be seen as an IT supermarket. In my post about [Entry-Level iSCSI Offerings], I discuss how Dell's acquisition of EqualLogic was a signal that it was trying to get away from selling EMC specialty shop products, and building up its own set of offerings internally.
Cisco is new on the server scene, but has already made quite a splash. Here, I have to agree with Chuck's logic: the only time it makes sense to buy EMC disk storage at all is when it is part of an integrated "V-block". This is not really an IT supermarket situation, instead you park your car at the "Acadia Mini-Mall" and get what you need from Trader Joe's, Cisco UCS, and VMware stores.
But wait, if what you want is running VMware on Cisco servers, you might be better off with IBM System Storage N series or NetApp storage. In his blog post about [Enhanced Secure Multi-Tenancy], fellow Blogger Val Bercovici (NetApp) provides a convincing argument of why Cisco and VMware run better on an "N-block" rather than a "V-block". IBM N series provides A-SIS deduplication, and IBM Real-time Compression can provide additional capacity and performance improvements. That might be true, but whether you get your storage from EMC, NetApp or IBM, to me, you are still working with three different vendors in any case.
Of course, following Chuck's logic, it makes more sense for people with IBM servers, whether they be mainframes, POWER systems or x86 machines, to integrate these with IBM storage, IBM software and IBM services. IBM is the leading reseller of VMware, but also has a lot of business with Microsoft Hyper-V, Citrix Xen, Linux KVM, PowerVM, PR/SM and z/VM. While IBM has market leading servers, disk and tape systems, to compete for those RFP bids that just ask for one component or another, it prefers to sell fully-integrated systems, which IBM has been doing successfully since the 1950s.
Back in 2007, I mentioned how IBM's fully-integrated InfoSphere Balanced Warehouse [Trounced HP and Sun]. For business analytics, IBM offers the fully-integrated [IBM Smart Analytics Systems]. Today, IBM expanded its line of fully-integrated private cloud service delivery platforms with the announcement of the [IBM CloudBurst for on Power Systems], which does for POWER7 what the IBM CloudBurst for System x, Oracle Exalogic, or Acadia's V-block, do for x86.
IBM estimates that private clouds built on Power systems can be up to 70 percent less expensive than stand alone x86 servers.
Before he earned his PhD in Mechanical Engineering, my father was a car mechanic. I spent much of my teenage years covered in grease, helping my father assembling cars, lifting engines, and rebuilding carburetors. Certainly this was good father-son time, and I certainly did learn something in the process. Like the automobile industry, the IT industry has matured, and it makes no financial sense to build your own IT infrastructure from parts from different vendors.

It's Tuesday, and you know what that means... IBM Announcements!
IBM System Storage ProtecTIER
Today, IBM refreshed its IBM System Storage ProtecTIER data deduplication family with new hardware and software. On the hardware side, The [TS7650G gateway] now has 32 cores and 64GB RAM. The [TS7650 Appliance] now has 24 cores and 64GB of RAM, and the [TS7610 Appliance Express] has 4 cores and up to 16GB of RAM.
On the software side, all of these now support Symantec's proprietary "OpenStorage" OST API. This applies across the board, from the [Enterprise Edition], [Appliance Edition], and the [Entry Edition]. For those using Symantec NetBackup as their backup software, the OST API can provide advantages over the standard VTL interface.
IBM Systems Director Storage Control
The second announcement has an interesting twist. I could file this in my "I Told You So" folder. Offiically, it's called the [Cassandra Complex], where you accurately predict how something will turn out, but being unable to convince anyone else of what the future holds.
About ten years ago, I was asked to be lead architect of a new product to be called IBM TotalStorage Productivity Center, which was later renamed to IBM Tivoli Storage Productivity Center. This would combine three projects:
Tivoli Storage Resource Manager (TSRM)
Tivoli SAN Manager (TSANM)
Multiple Device Manager (MDM)
The first two were based on Tivoli's internal GUI platform, and the MDM was a plug-in for IBM Systems Director. I argued that administrators would want everything on a single pane of glass, and that we should bring all the components under a common GUI platform, such as IBM Systems Director. Unfortunately, management did not agree with me on that, and preferred instead to leave each interface alone to minimize development effort. The only "unification" was to give them all similar sounding names, four components packaged as single product:
Productivity Center for Data (formerly TSRM)
Productivity Center for Fabric (formerly TSANM)
Productivity Center for Disk (formerly MDM)
Productivity Center for Replication (formerly MDM)
While this management decision certainly allowed version 1 to hit the market sooner, this was not a good "first impression" of the product for many of our clients.
In 2002, IBM acquired Trellisoft, Inc. which replaced the internally-developed TSRM with a much better interface, but again, this was different GUI than the other components. A "launcher" was created that would launch the various disparate interfaces for each component for Version 2. At this point, we have different development teams scattered in five locations, with the first two components being developed by the Tivoli software team, and the other two components being developed by the System Storage hardware team.
Often times, when a technical lead architect and management do not agree, things do not end well. The lead architect has to leave the product, and management is forced to take alternative actions to keep the product going. In my case, management considered the idea of a common GUI as an expensive "nice-to-have" luxury we could not afford, but I considered this a "must-have". I moved on to a new job within IBM, and management, unable to continue without my leadership, gave up and handed the entire project over to the Tivoli Software team.
The Tivoli Software team took a whiff at the pile of code and agreed that it stunk. Dusting off my original design documents, they pretty much discarded most of the code and re-wrote much from scratch, with a common database, common app server, and common GUI platform. Unfortunately, Productivity Center for Replication was held up waiting for some hardware prerequisites, but the other three components would be packaged together as "Productivity Center v3 - Standard Edition" and was a big improvement over the prior versions.
In Version 4, TotalStorage Productivity Center was renamed to Tivoli Storage Productivity Center, and the Replication component was brought into the mix. A scaled-down version packaged as Productivity Center "Basic Edition" was made available as a hardware appliance named "System Storage Productivity Center" or SSPC. The idea was to provide a pre-installed 1U-high hardware console that had the basic functions of Productivity Center, with the option to upgrade to the full Tivoli Storage Productivity Center with just license keys.
So, now, years later, management recognizes that a common GUI platform is more than just a "nice-to-have". IBM now support three very specific use cases:
1. Administration for a single product
For small clients who might have only a single IBM product, IBM is now focused on making the GUI browser-based, specifically to work with the Mozilla Firefox browser, but any similar browser should work as well. The new IBM Storwize V7000 GUI is a good example of this.In this case, the browser serves as the common GUI platform.
2. Administration for both servers and storage devices
For mid-sized companies that have administrators managing both servers and storage, IBM announced this month the new [IBM Systems Director Storage Control v4.2.1] plug-in, which provides Tivoli Storage Productivity Center "Basic Edition" support. This allows admins already familiar with IBM Systems Director for managing their servers to also manage basic storage functions. This is the "I Told You So" moment, connecting server and storage administration under the IBM Systems Director management platform makes a lot of sense, it did when I came up with the idea 10 years ago! Hmmmm?
3. Administration for just the storage environment
For larger companies big enough to have separate server and storage admin teams, IBM continues to offer the full Tivoli Storage Productivity Center product for the storage admins. The most recent release enhanced the support for IBM DS8000, SVC, Storwize V7000 and XIV storage systems.
Today, analysts consider IBM's [Tivoli Storage Productivity Center] one of the leading products in its category. I am glad my original vision has finally come to life, even though it took a while longer than I expected.

Well, I am off on a much-needed vacation. For my American readers, this weekend represents our "4th of July" Independence Day holiday. What better way to celebrate than to drive hundreds of miles from one side of the country to the other? In this case, from the North side down to the South side.
I am armed with two books on this subject. The first, is part of a series on American Road Trips, which details the roadside attractions to be found along the Great River Road. We will start up in Minnesota, and work our way Southward, covering a total of eight states in eight days along the Mississippi River.
The second book is Alton Brown's "Feasting on Asphalt, the River Run". This book describes Alton's ride Northward up the Mississippi river, detailing the restaurants and foods he enjoyed, so I will have to read the chapters in reverse.
Special thanks to Roy Buol, mayor of Dubuque, Iowa that I [met in Scottsdale earlier this year] for the idea to come visit his fine city, considered one of the Smarter Cities in the USA, thanks to IBM technology.
I don't know if I will have internet access along the way, or have the time and/or energy to blog, tweet (@az990tony) or upload photos during the trip. We'll see.
Well it's Tuesday, which means its time to look at recent announcements.While I was on vacation last week, IBM made a lot of storage announcements October 23.Josh Krischer gives his summary on WikiBon [October 2007 Review].Austin Modine of the The Register went so far as to say that [IBM goes crazy with storage system updates].
IBM System Storage DS8000 series
This is "Release 3" software/microcode upgrades on our existing "Turbo" hardware.
IBM FlashCopy SE -- Here "SE" stands for Space Efficient. Rather than allocating a full 100% of the space for the FlashCopy destination, you can set aside just a fraction, and this will hold all the changed blocks, similar to whatIBM already offers on the DS4000 series.
Dynamic Volume Expansion -- In the past, if you needed more space for a LUN, you had to carve out a newer one elsewhere, and then copy the data over from the old to the new, leaving the old LUN around to be re-used or leftstranded. With this enhancement, you can just upgrade the LUN in place, making it bigger as needed, similar to whatIBM already offers on the DS4000 series and SAN Volume Controller. This applies to CKD volumes for the System zmainframe users out there as well.
Storage Pool Striping -- striping volumes across RAID ranks to eliminate or reduce hot-spots, and provide betterload balancing. Many used SAN Volume Controller in front of the DS8000 to do this, but now you can do it natively inthe DS8000 itself.
z/OS Global Mirror Multiple Reader -- for System z customers, "z/OS Global Mirror" is the new name for XRC. Thisenhancement improves the throughput of sending updates to the remote disaster recovery location.
DS Storage Manager enhancements, the element manager software has been enhanced, and is pre-installed on the new IBM System Storage Productivity Center, which I will talk about below.
Intermix of DS8000 machine types -- this is especially useful to allow new frames to have co-terminating warrantieswith the base units. In other words, as you expand your system, you can ensure that the entire chunk of iron runs outof warranty all at the same time, to simplify your decision making process to upgrade or contract for extended service.
One of the biggest complaints about IBM TotalStorage Productivity Center is that it is software that needs to beinstalled on its own server, and that this installation process can take a day or two. Why wait? Now you can havea hardware console that has the DS8000 Storage Manager software, SVC Admin Console software, and IBM TotalStorageProductivity Center "Basic Edition" pre-installed. Here are the key features.
Pre-installed and tested console
DS8000 R3 GUI integration
Cohabitation of SVC 4.2.1 GUI and CIMOM
Automated device discovery
Asset and capacity reporting, including tape library support
Our "Release 9" applies across the board, from N3000 to N5000 to N7000 series models, includingnew host bus adapters, and the new Data OnTAP 7.2.4 release level.
The Virtual File Manager (VFM) was announced as one of our latest [Storage Virtualization Solutions]. VFMprovides a global namespace that aggregates the file systems from Linux, UNIX, and Windows file servers, as well asN series storage, into a consolidated environment.
IBM's virtual tape library (VTL) for the distributed systems platform, has been enhanced to provide:
Up to 12TB of disk cache, using 750GB SATA disk.
F05 Tape Frames installed as TS7520 base units through a 32 port fibre channel switch
Support for LTO generation 4 tape drives, both as virtual tape drives and as physical tape drives within IBM automated tape libraries attached to the TS7520. This allows you to use Encryption capabilities of LTO4.
DS3000 series now supports SATA disk, and can be attached to AIX and Linux on System p servers. This appliesto the DS3200, DS3300 and DS3400 models.See the [DS3000 Announcement Letter] for more details.
This week, Tuesday, Wednesday and Thursday, I am at the IBM Dynamic Infrastructure Executive Summit at the beautiful Fairmont Resort in Scottsdale, Arizona. This is a mix of indoor and outdoor meetings, one-on-ones with IBM executives, and main-tent sessions.
The Solutions Showcase will cover the following:
As the bar for performance gets higher and the need to manage, store and analyze massive amounts of information escalates, systems must scale to meet the needs of the business. The latest server and storage technology innovations including: POWER7, eX5, XIV, ProtecTIER, SONAS, and System z Solution Editions.

Next Monday, September 1, 2008, marks my two year "blogoversary" for this blog!
I won't be blogging on Monday, of course, because that is [Labor Day] holiday here in the United States.
(From a Canadian colleague: US is not the only country who celebrates Labor Day on the first weekend in September. Canada also celebrates Labour Day on the first weekend in September. It's the only holiday(other than Christmas/New Years) where we are in sync with US. Our Thanksgiving Days are different as is your July 4 vs our July 1. But for Labour Day we are one with the Borg...)
(From an Australian colleague: each province of Australia has its own day to celebrate Labor Day, see [Australia Public Holidays])
The rest of the world celebrates Labor Day on May 1, but the USA celebrates this on the first Monday of September, which this year lands on September 1.Originally, the day is intended to be a "day off for working citizens", IBM is kind enough to let managers and marketingpersonnel have the day off also. (Not that anyone is going to notice no press releases next Monday, right?)
I started this blog on September 1, 2006 as part of IBM's big["50 Years of Disk Systems Innovation"] campaign. IBM introduced the first commercial disk system on September 13, 1956 and so the 50th anniversary was in 2006. Last year, IBM celebrated the 55th anniversary of tape systems.
Several readers have asked me why I haven't talked about recent current events, such as the Olympic Games in Beijing, or the U.S. National Conventions for the race for U.S. President. I have to remind them of one of the key precepts of IBMblogging guidelines:
8. Respect your audience. Don’t use ethnic slurs, personal insults, obscenity, or engage in any conduct that would not be acceptable in IBM’s workplace. You should also show proper consideration for others’ privacy and for topics that may be considered objectionable or inflammatory - such as politics and religion.
I made subtle references to my senator from Arizona, John McCain, in my post [ILM for my iPod], and to Barack Obama in my post [Searching for matching information]. I don't think anyone would mind that I send a "Happy Birthday!" wish to both of them.Senator McCain turns 72 years old today, and Senator Obama turned 47 years old earlier this month.
And lastly, Tucson itself [celebrates this entire month] its 233rd birthday. That's right,Tucson, the 32nd largest city of the USA, and headquarters for IBM System Storage, is older than the USA itself.While the Tucson area has been continuously inhabited by humans for over 3500 years, it officially became Tucsonon August 20, 1775.
Fellow blogger Justin Thorp has opined that [blogging is like jogging]. Somedays, you are just too busy to do it, and other days, you make time for it, because you know it is important.For the record, it is not my job to blog for IBM, that ended last September 2007. I continue to blog anyways because I have benefited from it, both personally and professionally.I want to thank all of you readers out there for making this blog a great success! Being named one of the top 10 blogs of the IT storage industry by Network World, two back-to-back Brand Impact awards from Liquid Agency, and recently earning a "31" Technorati ranking, has really helped keep me going.
So, I look forward to next month, and beginning my third year on this blog. I am sure there will be lots of surprises and announcements you can all look forward to in the next coming weeks and months that I will have plenty to write about.
Last week's earthquake in Haiti reminds us all how fragile systems can be. Part of a complete Information Infrastructure is Information Security. Back in 2006, IBM [acquired Internet Security Services]. This week, IBM announces two sets of ISS Data Security Services: These services can include assessments of your current environment, running workshops to help gather requirements, help design security policies, and even follow through with implementation.
Endpoint Data Protection
Here "endpoint" refers to laptops, desktops, PDAs and smart phones. Not surprisingly, more and more mobile employees are relying on data stored on these endpoint devices, and they need to be protected and secure. [Endpoint Data Protection services] includings software, consulting and implementation of a solution that fits your environment.
Enterprise Content Protection
Here "enterprise content" refers to data that is stored centrally, such as a data center, and accessed over one or more networks. [Enterprise Content Protection services] will evaluate the data that is most sensitive, determine the various formats, identify risks, and provide guidance on how best to protect. Software is available to identify network exits and leakage points.
Both of these services include implementation of help desk support as well. To learn more, check out the ISS [Virtual Briefing Center].
Many people have asked me if there was any logic with the IBM naming convention of IBM Systems branded servers. Here's your quick and easy cheat sheet:
System x -- "x" for cross-platform architecture. Technologies from our mainframe and UNIX servers were brought into chips that sit next to the Intel or AMD processors to provide a more reliable x86 server experience. For example, some models have a POWER processor-based Remote Supervisor Adapter (RSA).
System p -- "p" for POWER architecture.
System z -- "z" for Zero-downtime, zero-exposures. Our lawyers prefer "near-zero", but this is about as close as you get to ["six-nines" availability] in our industry, with the highest level of security and encryption, no other vendor comes close, so you get the idea.
But what about the "i" for System i? Officially, it stands for "Integrated" in that it could integrate different applications running on different operating systems onto a [COMMON] platform. Options were available to insert Intel-based processor cards that ran Windows, or attach special cables that allowed separate System x servers running Windows to attach to a System i. Both allowed Windows applications to share the internal LAN and SAN inside the System i machine. Later, IBM allowed [AIX on System i] and [Linux on Power] operating systems to run as well.
From a storage perspective, we often joked that the "i" stood for "island", as most System i machines used internal disk, or attached externally to only a fewselected models of disk from IBM and EMC that had special support for i5/OS using a special, non-standard 520-byte disk block size. This meant only our popular IBM System Storage DS6000 and DS8000 series disk systems were available. This block size requirement only applies to disk. For tape, i5/OS supports both IBM TS1120 and LTO tape systems. For the most part,System i machines stood separate from the mainframe, and the rest of the Linux, UNIX and Windows distributed serverson the data center floor.
Often, when I am talking to customers, they ask when will product xyz be supported on System z or System i?I explained that IBM's strategy is not to make all storage devices connect via ESCON/FICON or support non-standard block sizes, but rather to get the servers to use standard 512-byte block size, Fibre Channel and other standard protocols.(The old adage applies: If you can't get Mohamed to move to the mountain, get the mountain to move to Mohamed).
On the System z mainframe, we are 60 percent there, allowing three of the five operating systems (z/VM, z/VSE and Linux) to access FCP-based disk and tape devices. (Four out of six if you include [OpenSolaris for the mainframe])But what about System i? As the characters on the popular television show [LOST] would say: It's time to get off the island!
Last week, IBM announced the new [i5/OS V6R1 operating system] with features that will greatly improve the use of external storage on this platform. Check this out:
POWER6-based System i 570 model server
Our latest, most powerful POWER processor brought to the System i platform. The 570 model will be the first in the System i family of servers to make use of new processing technology, using up to 16 (sixteen!) POWER6 processors (running at 4.7GHZ) in each machine.The advantage of the new processors is the increased commercial processing workload (CPW) rating, 31 percent greater than the POWER5+ version and 72 percent greater than the POWER5 version. CPW is the "MIPS" or "TeraFlops" rating for comparing System i servers.Here is the[Announcement Letter].
Fibre Channel Adapter for System i hardware
That's right, these are [Smart IOAs], so an I/O Processor (IOP) is no longer required! You can even boot the Initial Program Load (IPL) direclty from SAN-attached tape.This brings System i to the 21st century for Business Continuity options.
Virtual I/O Server (VIOS)
[VirtualI/O Server] has been around for System p machines, but now available on System i as well. This allows multiplelogical partitions (LPARs) to access resources like Ethernet cards and FCP host bus adapters. In the case of storage, the VIOS handles the 520-byte to 512-byte conversion, so that i5/OS systems can now read and write to standard FCP devices like the IBM System Storage DS4800 and DS4700 disk systems.
IBM System Storage DS4000 series
Initially, we have certified DS4700 and DS4800 disk systems to work with i5/OS, but more devices are in plan.This means that you can now share your DS4700 between i5/OS and your other Linux, UNIX and Windowsservers, take advantage of a mix of FC and SATA disk capacities, RAID6 protection, and so on.
To call [IBM PowerVM] the "VMware for the POWER architecture" would not do it quite justice. In combination with VIOS, IBM PowerVM is able to run a variety of AIX, Linux and i5/OS guest images.The "Live Partition Mobility" feature allows you to easily move guest images from one system to another, while they are running, just like VMotion for x86 machines.
And while we are on the topic of x86, PowerVM is also able to represent a Linux-x86 emulation base to run x86-compiled applications. While many Linux applications could be re-complied from source code for the POWER architecture "as is", others required perhaps 1-2 percent modification to port them over, and that was too much for some software development houses. Now, we can run most x86-compiled Linux application binaries in their original form on POWER architecture servers.
BladeCenter JS22 Express
The POWER6-based [JS22 Express blade] can run i5/OS, taking advantage of PowerVM and VIOS to access all of the BladeCenterresources. The BladeCenter lets you mix and match POWER and x86-based blades in the same chassis, providing theultimate in flexibility.
This week, I will be in Las Vegas for the 30th annual [Data Center Conference]. For those on Twitter, follow the conference on hashtag #GartnerDC, and follow me at [@az990tony]. IBM is a Global Partner and Platinum Sponsor for this event. Here is a recap of some of the Monday morning keynote sessions:
Welcome and Introduction
Monday morning kicked off with a welcome introduction from the conference coordinators. This is the highest attendance for this conference in its 30 year history, with 60 percent of the attending for their first time, and 18 percent only once before. This is the fourth time I am attending. Half of the attendees represent corporations with 20,000 employees or more, the other half from smaller companies and government agencies. The top five industries represented are financial services, public sector, healthcare, manufacturing, and energy.
This conference uses a clever "interactive polling" where hand-held devices can be used to select choices, and results of over 800 voters are presented immediately on the big screen.
For IT budgets, 42 percent plan to increase next year, 32 percent flat, and 26 percent lower, which are similar to the numbers last year. Of nine different IT challenges, the top three were managing storage growth, power/cooling issues, and adopting a Cloud strategy.
Top 10 Trends and how they will impact Data Center IT
The analyst presented top 10 business, technology and societal trends that will impact IT. He added a last-minute eleventh issue that he felt will impact everyone in 2012:
Consumerization and the Tablet. Back in 1997, a GB of flash memory cost $7,992 US dollars, and today that same GB costs only 25 cents. Employees are bringing their own devices to the workplace, and expecting IT support.
Infinite Data Center. You may never have to expand your floorspace again. Improvements in server and storage density can allow you to continually upgrade in place.
Energy Management. Data centers consume 100x more energy than the offices they support. The cost of energy is on part with IT equipment. Energy management is becoming an enterprise-wide discipline. A key performance indicator (KPI) can be "compute per kW" or "compute per Square foot".
Context Awareness. There are hundreds of thousands of apps for Android-based smart phones and iPhones. Context awareness allows an app to help business travelers in airports know what restaurants are nearby, their flight status, and alternate flights available, based entirely on their location.
Hybrid Clouds. By 2013, over 60 percent of cloud adoption will be to redeploy existing apps like email. Some 80 percent of cloud initiatives will be private or hybrid configurations. Customers want "good enough" technology, and thus Cloud will be mostly an augmentation strategy.
Fabric Computing. The opposite of fully-integrated stacks is the notion of having compute, memory and storage joined together via an interconnect fabric with software to manage the entire environment.
IT Complexity. Robert Glass's Law states that for every 25 percent increase in functionality, there is a 100 percent increase in complexity. See Roger Session's whitepaper [The IT Complexity Crisis: Danger and Opportunity] for more on this.
Patterns and Analytics. Big data and business analytics is a key platform. This is expected to grow 60 percent CAGR.
Impact of Virtualization. Virtualizing your environment should be considered a continuous process, not a one-time project. Many companies are running x86 servers at less than 55 percent, which the speaker considers under-utilized. Virtual Desktop Infrastructure (VDI) is a trade-off, may cost more but have other business benefits to consider. The problem is that many IT shops are organized vertially (a server team, storage team, network team) but problems surface horizontally, and there is no "ownership" for the resolution. Some use "tiger teams" to address this. Companies should reward lateral thinking.
Social Media. Of the ommunications on cell phones by college students, 98.4 percent are text messages, and only 1.6 percent voice phone calls. People search Google for "what was", but they search Twitter for "what is". Most of the growth on Twitter are in the 39-52 year-old demographic. The analyst felt that if your company is blocking or restricting access to facebook, twitter, youtube or other social networking sites, then shame on you. I agree!
Flooding in Thailand. Over two million square feet of HDD production space were flooded, and this will impact HDD prices for 2012. Already, a 2TB drive that was selling for $79 at local store is now selling for $190.
How To Get Your CFO's Support For Strategy and Funding
In the first of a series of "mastermind interviews", the analyst interviewed their own CFO Chris Lafond. Ultimately, it is about business results. They have grown annual 15-20 percent, from 250 million in 2003 to 1.3 billion US dollars in 2011 for annual revenue, 4600 employees, doing business in 85 countries. The company is focused on three business areas: Research, Consulting, and Events like this one. Chris does not approve 3-5 year projects, and instead requests projects be broken up into year-long phases. ROI can be very misleading, and he asks instead for benefits and contributions to initiatives.
It is important to keep the horse in front of the cart. Accounting departments should not drive business decisions. For example, companies should not move to the public cloud just so that the accounting department can shift from CAPex to OPex. Try to depreciate as soon as possible. Likewise, green technologies and social responsibility are factors, but not drivers of business decisions. Acquisitions are a natural evolution of the market, so risk mitigation strategies should be in place in case your vendor of choice is acquired by someone you don't like.
For BC/DR planning, the analyst has a single Data Center approach, but Chris indicated that IT is looking to expand this. Their single datacenter for one part of their business was in Florida, and the other in Massachusetts, and both impacted by Hurricanes or Earthquakes recently.
The "lightning round" asked Chris his thoughts, either thumbs up, thumbs down, or neutral, on single ideas or concepts. I liked this part of the interview!
Chargeback? Thumbs down. He doesn't feel you should have internal fighting over charge rates. He prefers showback instead.
BYO Device with stipend? Thumbs down, but inevitable. Giving people a chunk of money to buy their own laptop, smart phone or tablet of choice may wreak havoc on the IT department for support and service.
Telepresence? Thumbs down. Cool, but very expensive. I don't think people are prepared to exploit the benefits of this.
Corporate apps on public "app stores"? Thumbs down. Concerns over security and integration is main issue.
Access to Social Networks? Thumbs up. This is how employees communicate and collaborate. Don't stifle them doing the right things just because you are afraid they might waste 20 minutes on Facebook per day.
Your IT budget? It's up slightly 1-5 percent for 2012.
Cloud? Promising, some challenges related to integration and security.
Chris finished up with a story about an application team that indicated that they would need to make 100 customizations to an off-the-shelf general ledger financial application. Chris and the other executives asked to be presented each and every customization, and he was able to eliminate most of them.
Positive comments I heard from the audience was that these keynotes had real "meat" to them, and not just full of cliches and platitudes that is common for keynote sessions. I would have to agree.
Continuing my post-week coverage of the [Data Center 2010 conference], Thursday morning had some interesting sessions for those that did not leave town last night.
Interactive Session Results
In addition to the [Profile of Data Center 2010] that identifies the demographics of this year's registrants, the morning started with highlights of the interactive polls during the week.
External or Heterogeneous Storage Virtualization
The analyst presented his views on the overall External/Heterogeneous Storage Virtualization marketplace. He started with the key selling points.
Avoid vendor lock-in. Unlike the IBM SAN Volume Controller, many of the other storage virtualization products result in vendor lock-in.
Leverage existing back-end capacity. Limited to what back-end storage devices are supported.
Simplify and unify management of storage. Yes, mostly.
Lower storage costs. Unlike the IBM SAN Volume Controller, many using other storage virtualization discover an increase in total storage costs.
Migration tools. Yes, as advertised.
Consolidation/Transition. Yes, over time.
Better functionality. Potentially.
Shortly after several vendors started selling external/heterogeneous storage virtualization solutions, either as software or pre-installed appliances, major storage vendors that were caught with their pants down immediately started calling everything internally as also "storage virtualization" to buy some time and increase confusion.
While the analyst agreed that storage virtualization simplifies the view of storage from the host server side, it can complicate the management of storage on the storage end. This often comes up at the Tucson Briefing Center. I explain this as the difference between manual and automatic transmission cars. My father was a car mechanic, and since he is the sole driver and sole mechanic, he prefers manual transmission cars, easier to work on. However, rental car companies, such as Hertz or Avis, prefer automatic transmission cars. This might require more skills on behalf of their mechanics, but greatly simplifies the experience for those driving.
The analyst offered his views on specific use cases:
Data Migration. The analyst feels that external virtualization serves as one of the best tools for data migration. But what about tech refresh of the storage virtualization devices themselves? Unlike IBM SAN Volume Controller, which allows non-disruptive upgrades of the nodes themselves, some of the other solutions might make such upgrades difficult.
Consolidation/Transition. External virtualization can also be helpful, depending on how aggressive the schedule for consolidation/transition is performed.
Improved Functionality/Usability. IBM SAN Volume Controller is a good example, an unexpected benefit. Features like thin provisioning, automated storage tiering, and so on, can be added to existing storage equipment.
The analyst mentioned that there were different types of solutions. The first category were those that support both internal storage and external storage virtualization, like the HDS USP-V or IBM Storwize V7000. He indicated that roughly 40 percent of HDS USP-V are licensed for virtualization. The second category were those that support external virtualization only, such as IBM SAN Volume Controller, HP Lefthand and SVSP, and so on. The third category were software-only Virtual Guest images that could provide storage virtualization capabilities.
The analyst mentioned EMC's failed product Invista, which sold less than 500 units over the past five years. The low penetration for external virtualization, estimated between 2-5 percent, could be explained from the bad taste that left in everyone considering their options. However, the analyst predicts that by 2015, external virtualization will reach double digit marketshare.
Having a feel for the demographics of the registrants, and specific interactive polling in each meeting, provides a great view on who is interested in what topic, and some insight into their fears and motivations.
This week I'm in Argentina, teaching IBM Business Partners and sales reps about the latest System Storage products. Encouraged by my success on my Digital IBMer tour last month in Europe, I decided to get a SIM chip for my smartphone here in Buenos Aires.
I did my homework. There are three major mobile service providers that offer pre-paid GSM-based SIM chips: Claro, Movistar, and Personal. I arrived on Sunday morning, but thanks to the local [blue laws], none of them were open. I was able to walk around and find retail outlets for each within blocks of my hotel.
All three offer voice and SMS text messaging, but online reviews indicated that Movistar offered the best data plan. I was there at 9:30am sharp, the moment the Movistar store opened Monday morning. The lovely young lady behind the counter was quite helpful. She put the SIM chip in my phone, but then told me it might be an hour or two before it was activated. I would receive an SMS text message welcoming me to the Movistar network. She provided my new 12-digit phone number, along with instructions on how to check my balance (*444) or call for technical assistance (*611).
(FTC Disclosure: even though I am not in the United States as I write this, the U.S. Federal Trade Commission rules require that I mention that this blog post is not intended as a paid or celebrity endorsement for any of the cellphone service providers mentioned. I work for IBM, and this post is based entirely on my personal experience.)
Why not just use international roaming available on my US plan? International roaming is quite expensive! I made the mistake of uploading three hi-res photos to Flickr last year in New Zealand to discover this the hard way. Here is a comparison chart:
Voice calls (per minute)
$2.80 pesos (about $0.64 USD)
SMS text (per message sent)
$0.90 pesos (about $0.20 USD)
$10.00 pesos for 1GB across 2 days (about $2.27 USD)
(If your spouse or significant other threatens to leave you if you don't call her every day while out of the country, remind her that divorce attorneys are less expensive than these international roaming rates! Fortunately, all of my friends and family know this and are quite understanding if they don't here from me as often as they would like.)
The SIM chip cost only 30 pesos (about seven bucks). Normally, SIM chips come without credit, but their current promotion included 20 pesos credit for voice calls (enough for 7 minutes of talking), and 200 free SMS text messages.
Six hours later, my phone still was not yet activated. I returned to the store Monday afternoon to ask what was going on. She decided the chip must be bad, gave me a second one, and assigned me a new phone number. I would then have to wait again another hour or two for the welcome message.
Monday evening, a grey window pops up, "Bienvenidos a Movistar" so I thought it was activated, but it wasn't exactly the SMS text message the young lady told me would happen. Sure enough, neither *444 nor *611 worked, giving me voice responses that my phone is not yet activated, and please wait another hour.
Tuesday morning, I am back at the Movistar outlet. The young lady was not happy to see me. She confirmed my second chip was not yet activated, but felt she did nothing wrong. She insisted the problem was either with my phone, or with the Movistar main office, but that she did everything correctly by the book.
(I realize that the sales clerks at these outlet stores don't have a Ph.D. in digital telephony or electrical engineering. I was not angry, nor trying to blame her individually for all of the problems we encountered. Getting a smartphone manufactured in South Korea for the US market to work in Argentina is challenging enough. Given all the difficulties I had last month in Europe, I know it is not limited to Latin America.)
Either way, I told her, if we can't get my phone working, I would like my 30 pesos refunded and promised she would never see me again.
Her response was classic. She would rather not-see me-again because I was delighted with the Movistar service, rather than not-see me-again because we were unable to get it working. She offered to contact the main office to figure out what was going on, and that I should come back in an hour or two. She did not want to lose my business, nor have me go to one of her two main competitors. Now that's customer service!
Tuesday afternoon, I return. She now was instructed on how to do some basic problem determination. We put my new SIM chip into a test phone, and confirmed it was not my phone having problems. The chip did not work in the test phone either. She called the main office, and they were able to activate the chip in the test phone, and then she transferred the chip back to my phone. I asked her to please call my new phone number to confirm it was now working, and I was able to send a quick text message to confirm that was also working. The *444 indcated that my balance was now down to 19.29 pesos. Apparently, it cost me 71 centavos to receive her phone call.
(Just as we were wrapping up, a young man walks in with his phone wanting a SIM chip. None of the Movistar staff spoke English, he did not speak Spanish, but luckily I speak both fluently and was able to translate.
First, we confirmed his phone was still locked, and that he would need to contact his AT&T provider to get an unlock code. He should then come back with the unlock code and his passport to then buy the chip. He didn't understand why Movistar needed his passport for a pre-paid plan, so I had to explain to him at length Argentinian law, the Denied Parties List, the ongoing war against terror and drug trafficking, and how he would have to agree to their Terms and Conditions to use their service, even if there is no ongoing monthly service contract.
He thanked me, promised to return with both his unlock code and passport, and told me my English was "quite good"!)
The next step was to activate my data plan. For this, I would need to buy additional credit. Scratch cards to add credit to your pre-paid phone, referred to locally as "Tarjeta de Recarga", come in 20 and 30-peso denomnations, but are not sold at the Movistar outlet. Instead, the young lady told me to get one at any kiosk or corner convenience store.
As it turns out, not every convenience store offers these cards for Movistar, but after a few blocks, I was able to find one that did. The process is simple: call *444, follow the Spanish-language prompts, scratch off the back of the card, and enter the 16-digit code. I bought a 20-peso card (about $4.50 USD), followed the procedure, and got my confirmation text, indicating that I qualified for 10 extra pesos as a gift for being a new customer, so my new balance was now $49.29 pesos. Woo-hoo!
Now that my phone was armed with enough credit, all I had to do was send an SMS text message containing the word "Datos" to the Movistar phone number 2345. A text message response indicated my data plan was now active. I will have to do this every other day, as the plan is 1GB per 2-day period, but I have enough credit to last me the rest of the week here. To get my phone to detect the new status, I had to turn on data packet traffic, configure and validate the Access Point Name (APN) information, then reboot the phone.
The data plan service is based on the General Packet Radio Service [GPRS] protocol. GPRS is a best-effort service, resulting in variable throughput and latency that depends on the number of other users sharing the service concurrently. Speeds are comparable to dial-up rates, 56 to 114 Kbps.
For those of us spoiled on T-Mobile's 4G speeds in the USA, GPRS is terribly slow. But that's OK. I doubt I will go over the 1GB limit. Overall, I am quite pleased with my success. My phone is fully functional for the week, and all for less than the cost of a single glass of Malbec in the Hilton lobby bar!
For those who missed it, IBM announced last Tuesday encryption capability for the TS1120 drive, our enterprise tape drive that read and write 3592 cartridges. Do you need special cartridges for this? No! Use the sames ones you have already been using!
Continuing my romp through Australia and New Zealand, the last Storage Optimisation Breakfast of the week was Brisbane, which the locals here refer to as [Brisvegas], probably for all of the nightlife and casinos here.
The IBM office building is conveniently across the street from my hotel, the [Sofitel Brisbane]. The hotel also sits above central station, which allows quick transportation to the airport.
This time, we had a tag team of two people from James Cook University (JCU) to present their success story. First up was Kent Adams, the Director or Information Technology and Resources. JCU is recognized as one of the top 5 percent of Universities worldwide, and as a result, their data storage requirements are growing at 400 percent per year! Their latest purchase put out for RFP was for at least 40TB that could handle at least 20,000 IOPS. The winning solutions was an IBM XIV disk system.
Behind the scenes at all the events this week here in Australia were, from left to right, Natalie from GPJ Australia, the local subsidiary of the George P. Johnson events management we use in the states; Sonia Phillips, IBM Advisory Marketing Lead for Dynamic Infrastructure Optimisation and Cloud Computing, Demand Programs, for Australia and New Zealand; and Monika Lovgren, IBM Marketing and Execution Lead for Workload Optimised Systems for Australia.
The second speaker was Lee Askew, one of the Storage Administrators. Overall, the JCU team have been amazed at how well this box works. When they started it up, they expected to spend the next 24-36 hours formatting RAID ranks, but not with the XIV. It was ready in 2 minutes and they started provisioning storage right away. Their own tests to fail a drive found they can do a full rebuild to redundancy in 9 minutes. It took 8-36 hours on their previous disk array. Failing a full data module took only 75 minutes to bring back to redundancy.
After a long and tiring week, I was able to relax by walking through this beautiful King Edward park near the IBM building. This had a nice variety of plants and flowers, and with the surprise visit of a lizard about the length of my arm that crossed my path.
JCU also uses Asynchronous Mirror to replicate data to another XIV at distance. Again, as with all aspects of IBM XIV, the solution works as advertised. They are well positioned to grow from the 18,000 students they have today, to their target goal of 25,000 students they want to have by 2015.
Worldwide, IBM has done well with colleges and universities, and this was a great example of how partnering with IBM for your IT infrastructure can make a huge difference!
Wrapping up my coverage of the IBM Dynamic Infrastructure Executive Summit at the Fairmont Resort in Scottsdale, Arizona, we had a final morning of main-tent sessions. Here is a quick recap of the sessions presented Thursday morning. This left the afternoon for people to catch their flights or hit the links.
Data Center Actions your CFO will Love
Steve Sams, IBM Vice President of Global Site and Facilities, presented simple actions that can yield significant operational and capital cost savings. The first focus area was to extend the life of your existing data center. Some 70 percent of data centers are 10-15 years old or worse, and therefore not designed for today's computational densities. IBM did this for its Lexington data center, making changes that resulted in 8x capability without increasing footprint.
The second focus area was to rationalize the infrastructure across the organization. The process of "rationalizing" involves determining the business value of specific IT components and deciding whether the business value justifies the existing cost and complexity. It allows you to prioritize which consolidations should be done first to reduce costs and optimize value. IBM's own transformation reduced 128 CIOs down to a single CIO, and from 155 host data centers scattered were consolidated down to seven, and 80 web hosting data centers down to five. This also included consolidating 31 intranets down to a single global intranet.
The third focus area was to design your new infrastructure to be more responsive to change. IBM offers four solutions to help those looking to build or upgrade their data center:
Scalable Modular Data Center - save up to 20 percent than traditional deployments with turn-key configurations from 500 to 2500 square feet that can be deployed in as little as 8-12 weeks to an existing floorspace.
Enterprise Modular Data Center - save 40 to 50 percent with 5000 square foot standardized design for larger data centers. This modular approach provides a "pay as you grow" approach that can be more responsive to future unforeseen needs.
Portable Modular Data Center - this is the PMDC shipping container that was sitting outside in the parking lot. This can be deployed anywhere in 12-14 weeks and is ideal for dealing with disaster recoveries or situations where traditional data center floor plans cannot be built fast enough.
High Density Zone - this can help increase capacity in an existing data center without a full site retrofit.
Here is a quick [video] that provides more insight.
Neil Jarvis, CIO of American Automobile Association (AAA) for Northern California, Nevada and Utah (NCNU), provided the customer testimonial. Last September, the [AAA NCNU selected IBM] to build them an energy-efficient green data center. Neil provided us an update now six months later, managing the needs of 4 million drivers.
Virtualization - Managing the World's Infrastructure
Helene Armitage, IBM General Manager of the newly formed IBM System Software product line, presented on virtualization and management. Virtualization is becoming much more than a way of meeting the demand for performance, capability, and flexibility in the data center. It helps create a smarter, more agile data center. Her presentation focused on four areas: consolidate resources, manage workloads, automate processes, and optimize the delivery of IT services.
Charlie Weston, Group Vice President of Information Technology at Winn Dixie, one of the largest food retailers in the United States, with over 500 stores and supermarkets. The grocery business is highly competitive with tight profit margins. Winn Dixie wanted to deploy business continuity/disaster recovery (BC/DR) while managing IT equipment scattered across these 500 locations. They were able to consolidate 600 stand-alone servers into a single corporate data center. Using IBM AIX with PowerVM virtualization on BladeCenter, each JS22 blade server could manage 16 stores. These were mirrored to a nearby facility, as well as a remote disaster recovery center. They were also able to add new Linux application workloads to their existing System z9 EC mainframe. The result was to free up $5 million US dollars in capital that could be used to remodel their stores, and improve application performance 5-10 times. They were able to deploy a new customer portal on Linux for System z in days instead of months, and have reduced their disaster recovery time objective (RTO) against hurricanes from days to hours. Their next steps involves looking at desktop virtualization.
Redefining x86 Computing
Roland Hagan, IBM Vice President for IBM System x server platform, presented on how IBM is redefining the x86 computing experience. More than 50 percent of all servers are x86 based. These x86 servers are easy to acquire, enjoy a large application base, and can take advantage of readily available skilled workforce for administration. The problem is that 85 percent of x86 processing power remains idlea, energy costs are 8 times what they were 12 years ago, and management costs are now 70 percent of the IT budget.
IBM has the number one market share for scalable x86 servers. Roland covered the newly announced eX5 architecture that has been deployed in both rack-optimized models as well as IBM BladeCenter blade servers. These can offer 2x the memory capacity as competitive offerings, which is important for today's server virtualization, database and analytics workloads. This includes 40 and 80 DIMM models of blades, and 64 to 96 DIMM models of rack-optimized systems. IBM also announced eXFlash, internal Solid State Drives accessible at bus speeds.
The results can be significant. For example, just two IBM System x3850 4-socket, 8-core systems can replace 50 (yes, FIFTY) HP DL585 4-socket, 4-core Opteron rack servers, reducing costs 80 percent with a 3-month ROI payback period. Compared to IBM's previous X4 architecture, the eX5 provides 3.5 times better SAP performance, 3.8 times faster server virtualization performance, and 2.8 times faster database performance.
The CIO of Acxiom provided the customer testimonial. They were able to get a 35-to-1 consolidation switching over to IBM x86 servers, resulting in huge savings.
Top ROI projects to Get Started
Mark Shearer, IBM Vice President of Growth Solutions, and formerly my fourth-line manager as the Vice President of Marketing and Communications, presented a list of projects to help clients get started. There are over 500 client references that have successfully implement Smarter Planet projects. Mark's list were grouped into five categories:
Enabling Massive Scale
Increase Business Agility
Manage Risk, Compliance and Security
Organize Vast Amounts of Information
Turn Information into Insight
The attendees were all offered a free "Infrastructure Study" to evaluate their current data center environments. A team of IBM experts will come on-site, gather data, interview key personnel and make recommendations. Alternatively, these can be done at one of IBM's many briefing centers, such as the IBM Executive Briefing Center in Tucson Arizona that I work at.
This wraps up the week for me. I have to pack the XIV back into the crate, and drive back to Tucson. IBM plans to host another Executive Summit in the September/October time frame on the East coast.
This week, I will be in Auckland, New Zealand for the [IBM System x and System Storage Technical Symposium]. This is a three-day event, with 35 unique sessions and labs. The agenda is organized with a keynote session in the beginning, followed by 12 time slots over three days, each slot offering five different break-out session topics to choose from. Here is a recap of Day 1:
The keynote was led by Phil Tasker, IBM Business Unit Executive (BUE) for STG Education Programs in Growth Markets, then Matt Paterson, General Manager for Sales in New Zealand say a few words. IBM is in the Top 10 Training Hall of Fame, and conducts over 40,000 classes worldwide, resulting in over 1.3 million student days of instructions. IBM Systems Lab and Training technical hosts over three dozen conferences like this one every year. This is the first time that System x and Storage Symposium has been run in New Zealand, and based on the incredibly good turn-out, will probably be a regular event.
Matt Ziegler - HPC
Matt Ziegler, IBM Senior HPC Solutions Architect for the iDataPlex marketing team, gave an introdcution to HPC during the keynote, then provided more details in a break-out session.
In the High Performance Computing (HPC) market, IBM POWER used to be the dominant chipset, with over 200 of the top 500 supercomputers back in June 2001. Today, only about 50 use POWER. Rather, over 350 of the top 500 supercomputers use x86 instead. HPC represents a 6.3 percent growth opportunity for computer, 9.3 percent growth for storage, and 8.6 percent growth for services.
IBM's leadership in energy efficiency applies to HPC as well. In the "Green 500", a ranking based on MFLOPS/Watt, 19 of the top 25 are from IBM. IBM's iDataPlex is the most energy efficient x86 platform, at 401 MFLOPS per Watt.
Overall, x86 is growing. In 2005, x86 had 48 percent of the market, RISC/Itanium had 39 percent, and mainframe had 12 percent. In 2009, x86 grew to 56 percent, RISC/Itanium dropped to 33 percent, and mainframe to 11 percent. By 2014, Matt projects that x86 will be 63 percent, RISC/Itanium will drop to 30 percent, and mainframe to 7 percent.
The most popular form factor for x86 are blades. Growing from 8 percent in 2005, to 20 percent in 2009, and projected to be 33 percent by 2014.
IBM's Storage Strategy in the Era of Smarter Computing
I gave this presentation twice today. It has evolved quite a bit from the version I presented in Orlando last July. Attendees appreciated that my colorful analogies and stories helped them better understand the concepts of Big Data analytics, Workload-Optimized systems, and Cloud Storage offerings.
SONAS Product Review and Demo
Rich Swain presented IBM's Scale-Out Network Attached Storage (SONAS) and provided a live demo connecting to a box here in New Zealand. This is a topic I often present at the Tucson Executive Briefing Center, but it is always good to hear someone else's spin.
Phil Tasker invited everyone to the Welcome Reception after the last sessions. There was food and drink, and prizes! One person won an Xbox-360 game console, and two people won iPads.
Has it been a week already? I am here in Europe checking out various options for mobile, social media and cloud on my "Digital IBMer" tour. Here´s where we have been so far...
We landed at the Frankfurt airport, which will serve as our starting and ending point. It is close to Mainz where my IBM colleagues at the Executive Briefing Center for Germany is located. I looked throughout the airport for a SIM chip for my smartphone that worked in all European countries, but nobody had one for sale. We had lunch while we wait for the train to Brussels.
Our next stop was Brussels, capital of Belgium. The Belgians speak Flemish, which is like a Belgian version of Dutch, and French. I don´t speak Flemish nor Dutch, so I have been able to get by on French here. The Hotel Opera was near the central station, but we got off at the Bruxelles-Midi, thinking that Midi meant middle, or central of the city, but is Flemish (er.. make that French) for South instead, so we had a bit of walking to do!
Bruges is only an hour train ride from Brussels and is worth seeing. Our Eurail pass makes it easy just to go from city to city by train. Our particular one allows us first class travel through 23 countries for 15 contiguous days. We had lunch at the central square, and for dessert... Belgian Waffle-on-a-stick! Mine was covered in powdered sugar, and soon the rest of me was also.
Through tweets on Twitter, I was able to meet up with Stef, a local storage administrator and fan of my blog, and go out for beers. Stef was kind enough to lend me a pre-paid SIM chip for my phone that provided data plan while I am in Belgium! Thank you Stef!
Amsterdam, The Netherlands
Not surprisingly, Amsterdam is one of my favorite cities. It´s like Las Vegas without casinos. Our hotel, The Bulldog, is conveniently located in the center of town.
I met up with Joanne, a professional cellist (yes, she plays the Cello musical instrument for a living) who took us on a tour of the MuzikGebouw, which is where they hold concerts and events. Using the "Amsterdam City Guide" app from Travel Advisor on my smartphone, we followed one of their suggested self-guided walking tours. We also went to the Rijksmuseum, which is under construction, so only a subset of the art is on display.
From Amsterdam, we took a night train to Copenhagen. This is a 15-hour train ride, no dinner, but they give you breakfast. Men and women are in separate sleeping cars, and I was paired up with a business man, Danny, from Tiawan trying to sell clothing for firefighters.
Until now, I have managed with German, French and English, but I wasn´t sure about Danish, so I brought this "European Phrase Book" that has 14 languages. We stayed at the DanHostel, conveniently located near"Tivoli Park".
We have safely arrived to Berlin. Our train from Copenhagen to Hamburg went on a ferry boat to cross over the water! We are staying at Plus Berlin Hostel,which has a nice indoor swimming pool and dry sauna.
Until now, we have had beautiful sunny weather, but today is cold and dreary. We started out taking photos of all the graffiti in East Berlin we could find, but it started raining, so we changed plans and went to the world famous Pergamonmuseum.
Well, that´s my first week of adventure. Tomorrow, we leave for Prague in the Czech Republic!
Well, it's Tuesday again, and that means IBM announcements! Today we had a major launch, with so many products, services and offerings
that I can't fit them all into a single post, so I will split them up into several posts to give the attention they deserve. So, in this
post, I will focus on just the networking gear.
IBM Converged Switch B32
The "Converged" part of this switch refers to Converged Enhanced Ethernet (CEE), which is just a lossless Ethernet that meets certain standards to allow Fibre Channel over Ethernet (FCoE) that are still being discussed between Brocade and Cisco. Thankfully, IBM demanded both Brocade and Cisco stick to open agreed-upon standards, and the rest of the world gets to benefit from IBM's leadership in keeping everything as open and non-proprietary as possible.
The B32 ("B" because it was made by Brocade) starts with 24 10Gb Converged Enhanced Ethernet (CEE) ports, and then you can add eight Fibre Channel ports, for a total of 32 ports, hence the name B32. These are designed to be Top-of-Rack (TOR) switches. Basically, instead of having expensive optical cables for Ethernet and/or Fibre Channel out of each server, you have cheap twinax copper cables connecting the server's Converged Network Adapters (CNA) to this TOR switch, and then you can have the 10Gb Ethernet go to your regular Ethernet LAN, and your 8Gbps FC traffic go to your regular FC SAN. In other words, the CNA serves both the role of an Ethernet Network Interface Card (NIC) as well as a Fibre Channel Host Bus Adapter (HBA) card.
(You might see 8Gbps Fibre Channel represented as 8/4/2 or 2/4/8, this is just to remind you that these 8Gb FC ports can auto-negotiate down to 2Gbps and 4Gbps legacy hardware, but not 1Gbps. If you are still using 1Gbps FC, you need 4Gpbs SFP transceivers instead, shown often as 1/2/4 or 4/2/1.)
New SSN-16 module for Cisco directors and switches
When I present SAN gear to sales reps, I often get the question, "What is the difference between a switch and a director?" My quick and simple answer is that switches have fixed ports, but directors have slots that you can slide in different blades or expansion modules. The Cisco MDS9500 series are directors with slots, the three models provide a hint to their capacity. The last two digits represent the number of total slots, but the first two slots are already taken. In other words, model 9513 has 11 slots, model 9509 has seven slots, and model 9506 has four slots. You can have a 48-port blade in a slot, so in theory, you can have a maximum of 528 ports on the biggest model 9513.
However, if you want FCIP for disaster recovery, or I/O Acceleration (IOA) for remote e-vaulting tape libraries, you need a special 18/4 blade. This has 18 FC ports, four 1GbE ports and a special service processor that speaks FCIP or IOA. If you wanted two service processors for FCIP and two for IOA, you would need four of these blades, and that takes up slots that could have been used for 48-port blades instead. The solution? The new SSN-16 has sixteen 1GbE ports and four service processors, so with one slot, you can handle the FCIP and IOA processing that you previously used four cards, giving you three slots back to use with higher port-density cards.
Even better, you can put this new SSN-16 in the Cisco 9222i. The model 9222i is a "hybrid" switch with 22 fixed ports (18 FC ports, four fixed 1GbE ports, and a service processor, so basically the fixed port version of the 18/4 blade above), but it also has one slot! That one slot can be used for the SSN-16 to give you added FCIP or IOA capability.
For our mainframe clients, the FICON package includes four 24-port FICON blades and 96 SFP 4Gbps transceivers to fully populate them. Here is the IBM [Press Release].
Cisco Nexus 5000 series for IBM System Storage
The Cisco Nexus 5000 series is Cisco's entry into the Converged Enhanced Ethernet world, although Cisco sometimes refers to this as Data Center Ethernet (DCE), IBM will continue to use CEE when referring to either Brocade and Cisco gear. These are also Top-of-Rack aggregators that support CNA connections over cheaper twinax copper wires. Model 5010 has 10 ports that can be configured for either 1GbE or 10Gb CEE, 10 ports that are 10Gb CEE, and a slot for an expansion module. The Model 5020 has basically twice as much of everything, including two slots instead of one. Since 10Gb Ethernet does not auto-negotiate down to 1GbE, half the ports can be configured to run 1GbE instead. Frankly, that can be seen as wasting your precious Nexus ports with 1GbE connections, so you might find a 1GbE-to-10GbE aggregator that combines a dozen or more 1GbE to a few 10GbE links instead.
Today's announcement is that in addition to 10GbE and 4Gbps FC expansion modules, there is now an expansion module that supports 8Gbps Fibre Channel. Here is the IBM [Press Release].
Whether you choose Brocade or Cisco, nearly all of IBM System Storage disk and tape products can work today with Converged Enhanced Ethernet environments, either directly using iSCSI, NFS or CIFS, or using the FCoE methodology.
As you can see, it took me a whole post just to cover just our networking gear announcements, and I haven't even covered our disk, tape and cloud storage offerings. I'll get to these in later posts.
Well it's Tuesday again, and you know what that means? IBM Announcements!
(Update: I thought it was quite clever to announce the new z13 mainframe on January the 13th. A few [triskaidekaphobic] employees pointed out that certain [Greek and Spanish-speaking cultures] consider Tuesday the 13th to be an unlucky day. However, superstitious people should probably not work in IT, as it would be difficult for a worldwide company like IBM to avoid all the numbers that different cultures consider unlucky.)
You are cordially invited to join IBM on January 14 from 2:00pm to 4:30pm Eastern Standard Time (US) when IBM will share a whole new generation of IBM z Systems™ built to meet the needs of your digital business. Join us and learn how IBM z Systems are designed to:
Support the transaction growth and needs of the mobile generation and the Internet of things
Integrate data, transactions and analytics, for in-transaction insights and right-time actions
Provide secure, trusted and efficient cloud services with new economic models
Exploit new modern, open development environments, tooling and skills for greater returns
At this live streaming event, you will hear from a remarkable group of business and technology leaders who will share success stories, best practices and the exciting technology innovations and capabilities of the new generation of IBM z Systems. Go to the Registration page] to participate.
But what does this really mean? Are you thinking BFD?
(Update: For those not familiar with IT acronyms, BFD refers to "Bigger, Faster, Denser" -- the trend in IT to announce new generations that are merely bigger, faster, and/or denser versions of the previous generations. Fortunately, the z13 takes up the same amount of data center floor space -- 2 floor tiles = 2 square meters = 20 square feet -- and weighs approximately the same as the z196 and zEC12, so raised floor struts do not have to be strengthened or reinforced to take in this new system.)
You may have noticed that we are now talking about "z System" instead of "System z". This change was made to line up with IBM's change to "POWER Systems" from "System p". Leadership felt that dropping the stodgy old zEnterprise and giving the mainframe a "hip" new name would attract new emerging digital workloads like Cloud, Analytics, Mobile and Social.
This is not the first time IBM has renamed products in a series. While the IBM mainframe just celebrated its 50th anniversary last year, the "13" refers to the 13th generation of CMOS-based mainframe technology introduced in 1994. Here is a quick table to show you the names that have evolved over the years:
1 to 6
S/390 G1 to G6
zSeries z800 and z900
zSeries z890 and z990
9 to 10
System z9 and z10
System z196 and z114
zEnterprise zEC12 and zBC12
(Note: This change also corresponds to a completely restructuring of IBM into business units, eliminating its former hardware and software groups. The design and development of all mainframe-related hardware, software and middleware will be consolidated under the IBM Systems business unit. I will wait for IBM's 4Q financial results announcement on or after January 20 before I cover this in any more detail.)
The z13 machine itself has some unique differences from previous generations. Instead of a "Multi-chip Module" (MCM) that contained multiple processor and storage controllers on a single slab, the z13 uses Single-Chip Modules (SCM) that are either a single 8-core processor, or a single system controller, allowing them to be field replaceable units (FRU).
Previous generations organized the processors in 1 to 4 vertical "books". The problem was that if you had a single book system, you bought a lot of hardware infrastructure designed to support a full four books. In the new design, processors are organized into horizontal Central Processor Complex (CPC) drawers, with additional hardware infrastructure provided per drawer. This makes the lower-end models more affordable. Each drawer has six processor SCMs and two system controller SCMs, providing 39 to 42 usable cores per drawer. Models ranges from 30 to 141 usable cores, with the option to upgrade from one model to another as your needs grow.
The z13 provides N-2 generation compatibility. This means you can have the z196, zEC12 and z13 all participate in the same Parallel Sysplex. You will also be able to upgrade your z196 or zEC12 to the new z13 system.
The new z13 can have up to 10TB of memory, and this can be assigned entirely to a single Logical Partition, or LPAR. The system can be subdivided up to 85 LPARs, versus 60 on the previous generation. Currently, z/OS v1 can only have up to 1TB per LPAR, and z/OS v2 can only go up to 4TB, so I suspect this 10TB is planning for future OS releases.
The new z13 now offers Simultaneous Multithreading [SMT]. Initially, this will double the number of threads for IFL engines (supporting Linux and z/VM), and zIIP engines supporting DB2, Java, XML and IPsec workloads. IBM is eliminating the zAAP engines, since zIIP engines can do all of that. The new [Preview z/OS v2.2] will take advantage of this SMT capability.
To assist with database, analytics and multimedia workloads, the z13 offers Single Instruction, Multiple Data [SIMD] capability. This allows a single instruction to perform the same update or action across many data fields.
For those clients with zBX models 2 and 3, allowing you to run POWER-based AIX and x86-based Microsoft Windows and Linux operating systems on your mainframe, they will be able to upgrade to [zBX model 4 for the z13 System]. Now that IBM has sold off its x86 server business to Lenovo, I suspect it will also phase out the zBX offerings as well.
To handle emerging workloads of Cloud, Mobile and other Web applications, IBM will offer a new stronger and faster Crypto Express5S cryptographic adapter. The z13 will enhance public key support for constrained digital environments using Elliptic Curve Cryptography (ECC) for users such as Chrome, Firefox, and Apple's iMessage. The z13 will also minimize reformatting of databases with new exploitation of VISA format preserving encryption (FPE) for credit card numbers.
The z13 also made some enhancements for Linux clients. The zAware analytics that analyzes internal traces and logs for z/OS has been extended to support Linux on System z. For those who want to use GDPS Business Continuity and Disaster Recovery services, but don't want to develop z/OS skills for the "K" system, there will now be a Virtual GDPS appliance that will run self-contained z/OS. Lastly, IBM has made a statement of direction that it will support open source Linux KVM as a Linux-only alternative to z/VM hypervisor. OpenStack will support both this new Linux KVM as well as z/VM 6.3 release.
The PCIe bus has been upgraded to Gen3 at 16Gbps, from Gen2 used in the zEC12. These can be used for Coupling Facility Links, which are faster than the legacy 6 Gbps InfiniBand, which are also supported for legacy migration. People with z196 and zEC12 can either carry forward their I/O drawers they have previously purchased, or move the PCiE Gen2 cards into the new Gen3 drawers.
The new z13 will also support 16Gb FICON, using the new FICON Express5S cards. Here is my segue into storage, as you are probably now wondering when I was going to get to the storage part of the announcement!
IBM is also announcing corresponding changes to the DS8870 firmware and accessories to go with the z13 System. This includes:
FICON Dynamic Routing
Reduce cost with improved and persistent performance for supporting I/O devices. This feature will allow SAN directors to have both FICON and FCP share the same Inter-switch Links (ISL). This is especially useful for clients who use FCP with their Linux, z/VM, AIX or Windows workloads.
16Gb Host Adapters
Improve network performance with twice faster FC and FICON adapters, and minimize latency for database log writes with zHyperWrite and Metro Mirror. These 16Gb adapters can auto-negotiate down to 4Gb and 8Gb, so that the DS8870 can connect to both the new z13 mainframe, as well as older models.
Forward Error Correction
Preserve data integrity with more redundancy on the information transmitted via 16Gb adapters.
zHPF Extended Distances improvements
Increase remote data speed with 50 percent better I/O performance when accessing remote disk, typically after a HyperSwap. The "zHPF" acronym is short for z System High Performance FICON.
Improved resiliency capabilities while enhancing the value of FICON Dynamic Routing mentioned above. IBM is extending Workload Manager (WLM) Quality of Service (QoS) optimization that exists now for compute and storage to the SAN Fabric, allowing WLM policies to influence FICON traffic.
IBM zHyperWrite™ capability
Helps you achieve better DB2 log write performance when using Metro Mirror (PPRC) in a HyperSwap-managed environment. Log writes are sent directly to both DASD, freeing up Metro Mirror resources.
But don't just take my word for it, here are reviews of the new system from various journalists:
"They seem a computing odd couple: the mainframe, the old workhorse, and the smartphone, the cool-kid computer of today. But IBM has designed the latest version of the mainframe, which is being introduced on Wednesday, with the smartphone in mind. The new mainframe, the z13, has been engineered to cope with the huge volume of data and transactions generated by people using smartphones and tablets."
-- New York Times
"One customer enthusiastic about such features is Citigroup Inc., a longtime IBM user that favors mainframes for both reliability and security. 'Security is in the DNA of the mainframe,' said Martin Kennedy, Citi's managing director for platforms and storage. Another factor shaping the bank's needs, Mr. Kennedy said, is the rising volume of transactions carried out using smartphones and other mobile devices. Mainframes are particularly good at combining data from a variety of systems and presenting them to a user's mobile app, he said."
-- The Wall Street Journal
"IBM is introducing a new mainframe in a bet that clients will need its souped-up speed and security to handle a surge in consumers using smartphones for everything from banking to checking health-care records. The z13 system can encrypt and analyze data in real time and process 30,000 transactions a second, International Business Machines Corp. (IBM) announced today. That means faster and safer transactions for consumers on mobile phones."
"With the unveiling of the z13, IBM has taken its MobileFirst Platform to deliver even better performance and security than before, as it incorporates the fastest microprocessor in the world, server processors that are twice as fast as existing products, 300 percent additional memory and 100 percent more bandwidth analytics speed. Last year, IBM formed a partnership with Apple to help bring Apple's iDevices to business customers to boost sales, with IBM providing cloud and mobile analytics support."
-- The Street
"'We're driving toward a world where more and more people are using mobile devices, or embedded devices, to interact with systems,' John Birtles, director of IBM z Systems, tells WIRED. 'We need to make sure that those devices are secure, that the transaction's secure, and that our clients get the level of analytics that gives them opportunities to improve their businesses.'"
IBM mainframes are used to process the majority of financial transactions around the world, is well positioned to handle Cloud, Analytics, Mobile and Social workloads. The IBM DS8000 series disk is the #1 market leader for disk storage on mainframe environments.
Jon Toigo has a funny cartoon on his post, [As I Listen to EMC Brag on “New” Functionality…]. Basically, it pokes fun that many of us bloggers argue which vendor was first to introduce some technology or another. We all do this, myself included.
Recently, Claus Mikkelsen's, currently with HDS, [brought up accurately some past history from the 1990s], which is before many storage bloggers hired on with their current employers. Claus and I worked together for IBM back then, so I recognized many of the events he mentions that I can't talk about either. In many cases, IBM or HDS delivered new features before EMC.
I've been reading with some amusement as fellow blogger Barry Burke asked Claus a series of questions about Hitachi's latest High Availability Manager (HAM) feature. Claus was too busy with his "day job" and chose to shut Barry down. Sadly, HDS set themselves up for ridicule this round, first by over-hyping a function before its announcement, and then announcing a feature that IBM and EMC have offered for a while. The problem and confusion for many is that each vendor uses different terminology. Hitachi's HAM is similar to IBM's HyperSwap and EMC's AutoSwap. The implementations are different, of course, which is often why vendors are often asked to compare and contrast one implementation to another.
In his latest response,[how to mind the future of a mission-critical world], Barry reports that several HDS bloggers now censor his comments.That's too bad. I don't censor comments, within reason, including Barry's inane questions about IBM's products, and am glad that he does not censor my inane questions to him about EMC products in return. The entire blogosphere benefits from these exchanges, even if they are a bit heated sometimes.
We all have day jobs, and often are just too busy, or too lazy, to read dozens or hundreds of pages of materials, if we can even find them in the first place. Not everyone has the luxury of a "competitive marketing" team to help do the research for you, so if we can get an accurate answer or clarification about a product that is generally available directly from a vendor's subject matter expert, I am all for that.
This week, IBM made over a dozen announcements related to IBM storage products. Here is part 2 of my overview:
IBM System Storage® DS8000 series microcode
One of the advantages of acquiring XIV as IBM's other high-end disk system, is that it allows the DS8000 team to focus on the IBM i and z/OS operating systems. As a result, IBM DS8000 has over half the mainframe-attach market share.
For both the DS8700 and DS8800 models, IBM Easy Tier now support sub-LUN automated tiering across three storage tiers: Solid-State Drives, high-performance spinning disk drives (15K and 10K RPM), and high-capacity disk drives (7200 RPM).
For System z customers, the latest DS8000 microcode has synergy with z/OS and GDPS, now supporting 4x larger EAV volumes, faster high-performance FICON (zHPF), and Workload Manager (WLM) integration with the I/O Priority Manager. IBM has a world record SAP performance of 59 million account postings per hour. DB2 v10 for z/OS queries were measured at 11x faster using the new zHPF feature.
IBM System Storage® DS8800 systems
On the hardware side, the DS8800 now supports a fourth frame to hold a total over 1,500 disk drives. Yes, we have customers that three frames wasn't enough, and they wanted more.
IBM is now also offering new drive options. Small Form Factor (2.5 inch) drives now include 300GB 15K RPM drives, and a 900GB 10K RPM drives. But wait! There's more! The DS8800 is no longer a SFF-only box, it now allows for mixing in Large form factor (3.5 inch) drives, starting with the 3TB NL-SAS 7200 RPM drive.
IBM XIV® Storage System Gen3
We announced the XIV Gen3 already, but we have two enhancements.
First, we now offer a model based entirely on 3TB NL-SAS drives. If you are thinking, what IBM is going to put 3TB drives into everything? Yup. Once we go through all the pain and suffering of qualifying a drive, we make sure we get our money's worth!
Secondly, we have now an iPad application to manage the XIV. This has nothing to do with Apple CEO Steve Jobs passing away last week, it was merely coincidence.
IBM Real-time Compression Appliances™ STN6500 and STN6800 V3.8
The latest software for RtCA now supports Microsoft SMB v2, and enhanced reporting so that storage admins know exactly the benefits of the compression ratios of different file extensions.
IBM System Storage EXP2500 Express®
The EXP2500 is for direct-attach situations, like the IBM BladeCenter. IBM adds LFF 3.5-inch 3TB NL-SAS drives, SFF 2.5-inch 300GB 15K RPM SAS drives, and 900GB 7200 RPM NL-SAS drives.
My colleague Curtis Neal refers to these as "B.F.D" announcements, which of course stands for Bigger, Faster, Denser!
On his The Storage Architect blog, Chris Evans wrote [Twofor the Price of One]. He asks: why use RAID-1 compared to say a 14+2 RAID-6 configuration which would be much cheaper in terms of the disk cost? Perhpaps without realizing it, answers itwith his post today [XIV part II]:
So, as a drive fails, all drives could be copying to all drives in an attempt to ensure the recreated lost mirrors are well distributed across the subsystem. If this is true, all drives would become busy for read/writes for the rebuild time, rather than rebuild overhead being isolated to just one RAID group.
Let me try to explain. (Note: This is an oversimplification of the actual algorithm in an effortto make it more accessible to most readers, based on written materials I have been provided as partof the acquisition.)
In a typical RAID environment, say 7+P RAID-5, you might have to read 7 drives to rebuild one drive, and in the case of a 14+2 RAID-6, reading 15 drives to rebuild one drive. It turns out the performance bottleneck is the one driveto write, and today's systems can rebuild faster Fibre Channel (FC) drives at about 50-55 MB/sec, and slower ATA disk at around 40-42 MB/sec. At these rates, a 750GB SATA rebuild would take at least 5 hours.
In the IBM XIV Nextra architecture, let's say we have 100 drives. We lose drive 13, and we need to re-replicate any at-risk 1MB objects.An object is at-risk if it is the last and only remaining copy on the system. A 750GB that is 90 percent full wouldhave 700,000 or so at-risk object re-replications to manage. These can be sorted by drive. Drive 1 might have about 7000 objects that need re-replication, drive 2might have slightly more, slightly less, and so on, up to drive 100. The re-replication of objects on these other 99 drives goes through three waves.
Select 49 drives as "source volumes", and pair each randomly with a "destination volume". For example, drive 1 mapped todrive 87, drive 2 to drive 59, and so on. Initiate 49 tasks in parallel, each will re-replicate the blocks thatneed to be copied from the source volume to the destination volume.
50 volumes left.Select another 49 drives as "source volumes", and pair each with a "destination volume". For example, drive 87 mapped todrive 15, drive 59 to drive 42, and so on. Initiate 49 tasks in parallel, each will re-replicate the blocks thatneed to be copied from the source volume to the destination volume.
Only one drive left. We select the last volume as the source volume, pair it off with a random destination volume,and complete the process.
Each wave can take as little as 3-5 minutes. The actual algorithm is more complicated than this, as tasks complete early the source and volumes drives are available for re-assignment to another task, but you get the idea. XIV hasdemonstrated the entire process, identifying all at-risk objects, sorting them by drive location, randomly selectingdrive pairs, and then performing most of these tasks in parallel, can be done in 15-20 minutes. Over 40 customershave been using this architecture over the past 2 years, and by now all have probably experienced at least adrive failure to validate this methodology.
In the unlikely event that a second drive fails during this short time, only one of the 99 task fails. The other 98 tasks continue to helpprotect the data. By comparison, in a RAID-5 rebuild, no data is protected until all the blocks are copied.
As for requiring spare capacity on each drive to handle this case, the best disks in production environments aretypically only 85-90 percent full, leaving plenty of spare capacity to handle re-replication process. On average,Linux, UNIX and Windows systems tend to only fill disks 30 to 50 percent full, so the fear there is not enough sparecapacity should not be an issue.
The difference in cost between RAID-1 and RAID-5 becomes minimal as hardware gets cheaper and cheaper. For every $1 dollar you spend on storage hardware, you spend $5-$8 dollars managing the environment. As hardware gets cheaper still, it might even be worth making three copies of every 1MB object, the parallel processto perform re-replications would be the same. This could be done using policy-based management, some data gets triple-copied, and other data gets only double-copied, based on whether the user selected "premium" or "basic" service.
The beauty of this approach is that it works with 100 drives, 1000 drives, or even a million drives. Parallel processingis how supercomputers are able to perform feats of amazing mathematical computations so quickly, and how Web 2.0services like Google and Yahoo can perform web searches so quickly. Spreading the re-replication process acrossmany drives in parallel, rather than performing them serially onto a single drive, is just one of the many uniquefeatures of this new architecture.
Dan Galvan, IBM VP of Marketing for Storage, was the next speaker. With 300 billion emails being sent per day, 4.6 billion cell phones in the world, and 26 million MRIs per year, there is going to be a huge demand for file-based storage. In fact, a recent study found that file-based storage will grow at 60 percent per year, compared to 15 percent growth for block-based storage.
Dan positioned IBM's Scale-out Network Attached Storage (SONAS) as the big "C:" drive for a company. SONAS offers a global namespace, a single point of management, with the ability to scale capacity and performance tailored for each environment.
The benefits of SONAS are great. We can consolidate dozens of smaller NAS filers, we can virtualize files across different storage pools, and increase overall efficiency.
Powering advanced genomic research to cure cancer
The next speaker was supposed to be Bill Pappas, Senior Enterprise Network Storage Architect, Research Informatics at [St. Jude Children’s Research Hospital]. Unfortunately, St. Jude is near the flooding of the Mississippi river, and he had to stay put. An IBM team was able to capture his thoughts on video that was shown on the big screen.
Thanks to the Human Genome project, St. Jude is able to cure people. They see 5700 patients per year, and have an impressive 70 percent cure rate. The first genetic scan took 10 years, now the technology allows a genome to be mapped in about a week. Having this genomic information is making vast strides in healthcare. It is the difference of fishing in a river, versus putting a wide net to catch all the fish in the Atlantic ocean all at once.
Recently, St. Jude migrated 250 TB of files from other NAS to an IBM SONAS solution. The SONAS can handle a mixed set of workloads, and allows internal movement of data from fast disk, to slower high-capacity disk, and then to tape. SONAS is one of the few storage systems that supports a blended disk-and-tape approach, which is ideal for the type of data captured by St. Jude.
IBM's own IT transformation
Pat Toole, IBM's CIO, presented the internal transformation of IBM's IT operations. He started in 2002 in the midst of IBM's effort to restructure its process and procedures. They identified four major data sources: employee data, client data, product data, and financial data. They put a focus to understand outcomes and set priorities.
The result? A 3-to-1 payback on CIO investments. This allowed IBM to go from server sprawl to consolidated pooling of resources with the right levels of integration. In 1997, IBM had 15,000 different applications running across 155 separate datacenters. Today, they have reduced this down to 4,500 applications and 7 datacenters. Their goal is to reduce down to 2,225 applications by 2015. Of these, only 250 are mission critical.
Pat's priorities today: server and storage virtualization, IT service management, cloud computing, and data-centered consolidation. IBM runs its corporate business on the following amount of data:
9 PB of block-based storage, SVC and XIV
1 PB of file-based storage, SONAS
15 PB of tape for backup and archive
Pat indicated that this environment is growing 25 percent per year, and that an additional 70-85 PB relates to other parts of the business.
By taking this focused approach, IBM was able to increase storage utilization from 50 to 90 percent, and to cut storage costs by 50 percent. This was done through thin provisioning, storage virtualization and pooling.
Looking forward to the future, Pat sees the following challenges: (a) that 120,000 IBM employees have smart phones and want to connect them to IBM's internal systems; (b) the increase in social media; and (c) the use of business analytics.
After the last session, people gathered in the "Hall of the Universe" for the evening reception, featuring food, drinks and live music. It was a great day. I got to meet several bloggers in person, and their feedback was that this was a very blogger-friendly event. Bloggers were given the same level of access as corporate executives and industry analysts.
IBM has announced it has entered into a definitive agreement to acquire Texas Memory Systems, Inc. (TMS), a privately held Houston, Texas-based company with about 100 employees, that focuses on solid-state flash optimized systems and solutions, including the RamSan family of external rack-mounted storage, as well as PCIe cards for internal storage that fit inside servers.
I've mentioned Solid-State Drive storage quite a few times over the past few years in this blog, which included some great interactions with my friends over at Texas Memory Systems. Here's a quick look:
In my now infamous blog post [Hybrid, Solid State and the future of RAID], I resort to a deck of [Tarot cards] in an effort to fight [writer's block] responding to query about combining solid-state with spinning disk. In the original post, I poked fun at Texas Memory Systems having the slogan "World's Fastest Storage". Woody Hutsell, then VP of marketing for Texas Memory Systems, explained that the reason that TMS did not have faster benchmark results was because it did not have a million dollars to buy the fastest IBM UNIX server.
In my post [Good News and Bad News], I mentioned that Texas Memory Systems has an impressive SPC benchmark result. The Storage Performance Council [SPC] publishes the benchmarking industry standard by which all block-based storage devices are measured. It looks like the TMS performance test department finally got the million-dollar IBM server they needed for this.
My colleagues in marketing were not amused, afraid that mentioning small companies like TMS would give them a huge boost in marketing awareness, above and beyond what TMS could do on their own modest marketing budget, similar to the [Colbert Bump]. I could call it the Pearson Bump. If you first heard of Texas Memory Systems from my blog, or bought TMS products based on my discussion, please post a comment below!
IBM made history as the first major storage vendor to [break the 1 million IOPS barrier with Solid State Disk]. The project was known as "Quicksilver", and was able to demonstrate that a product like SAN Volume Controller with Solid-State Drives (SSD) can indeed provide a significant boost in performance to external disk arrays. The IBM 2145-CF8 and 2145-CG8 models allow up to four SSD in each node. I was asked not to blog the entire month of August, so that our upcoming September announcements would get more notice, but I couldn't resist covering Quicksilver. The original post had mentioned Texas Memory Systems, but were later removed to avoid the "Pearson Bump".
In my post [Day 2 IBM Storage University - Solutions Expo - TMS After-party], I mentioned that I attended the TMS after-party. Texas Memory Systems had just been qualified as Solid-State Drive (SSD) storage behind the IBM SAN Volume Controller, and the two products work extremely well together for IBM Easy Tier, the sub-volume automated tiering capability to optimize storage performance. I was able to catch up with my friend Erik Eyberg, and meet CEO and Founder Holly Frost.
Nearly half (43 percent) of IT decision makers say they have plans to use SSD technology in the future or are already using it in their datacenter. Solid-state can refer to both volatile Random Access Memory (RAM) and non-volatile Flash, and Texas Memory Systems has built solutions around both types. The survey question referred to non-volatile Flash Solid-State Drives (SSD) that do not require a battery to keep the data from fading away after the power goes out. Nearly all storage in the datacenter has volatile Random Access Memory (RAM).
Speeding delivery of data was the motivation behind 75 percent of respondents who plan to use or already use SSD technology. I would have thought this would have been 100 percent, but the other options included reduced energy consumption, and improved drive reliability, which are both also true with Solid-State Drives.
However, for those who were not using SSD today, the major factor was cost, according to 71 percent of respondents. On a Dollar-per-GB basis, Solid-State Drives continue to be anywhere from 10 to 25 times more expensive spinning disk. Last year's tsunami in Japan, and the floods in Thailand, have caused spinning disk prices to rise to cover component shortages, thereby shrinking the price gap between SSD and spinning disk.
Nearly half (48 percent) say they plan on increasing storage investments in the area of virtualization, cloud (26 percent) and flash memory/solid state (24 percent) and analytics (22 percent).
This month, I am pleased to announce the new [IBM STG Executive Briefing Center] website, representing a huge improvement over the previous website we had been using over the past two years. STG refers to IBM's Systems and Technology Group, the division that focuses on servers, storage, switches and the system software that makes them run. This new website is for the dozen STG EBCs that span the globe. The new website reminds me of this famous quote:
"Perfection is achieved, not when there is nothing left to add, but when there is nothing left to take away"
-- Antoine de Saint-Exupery
Let's take a quick look at what makes it so much better.
The previous website required registration. At every briefing, those of us who work in the EBCs had to pass around a sign-up sheet for email addresses from each attendee so that we could send them an invitation to register for the site. We would have a hard time reading people's handwriting, resulting in some emails coming back rejected.
Inspired by self-service gas stations, automated teller machines, and the many self-service portals of Cloud Computing, the new website has everything up-front, without registration. IBM Business Partners and sales representatives can easily request a briefing at any of the dozen briefing centers represented!
IBM-managed and IBM-hosted
We had a difficult time explaining to our attendees why our previous website was hosted on a lone machine and maintained by a third party. Think about it, IBM manages the data centers of over 400 clients. IBM has provided web hosting to the most mission critical workloads, with high levels of availability and reliability, and is recognized as one of the "Big 5" Cloud companies. I have done web design myself in my career, and we were terribly disappointed with the third party chosen to create and maintain our previous website, constantly having to point out errors in their HTML and CSS.
For the new website, IBM took back control. Staff from each EBC, myself included, came up with a simple page to bring the essence of each location to life. Special thanks to my colleage Hal Jennings, from the Austin EBC, for bringing this altogether!
Despite two years of manually registering attendees to use the previous website, Google Analytics showed that few people visited, and the few that did spent little time exploring the vast repository of content.
The new website is vastly simpler. The front page points to all twelve EBCs, and a single mouse click gets you to the location you are interested in, with all the details you need to make a decision to book a briefing, and the contact information to make it happen.
Elimination of Wasted and Duplicate Effort
In the previous website, we spent as much as 15 hours just to create, voice over, edit and produce a single 15-minute recorded presentation. Less than six percent of the previous website visitors watched more than five minutes of these videos, making us feel that most of our effort was wasted.
The EBC staff kept wasting their time, month after month, thanks to all-stick, no-carrot tactics that mandated minimums for contributions for more and more content that nobody was ever looking at. Even more disappointing was that much of our work duplicated the formal responsibilities of our IBM Marketing team. They weren't happy about this either, causing confusion between the roles of our two teams.
Finally, we said enough was enough! The new STG EBC website is a marvel in minimalism. If you want to see presentations, videos, expert profiles, or partake in on-going conversations, I welcome you to visit the [IBM Expert Network], the [IBM Storage YouTube Channel], and the [Storage Community] where they belong.
For those in the US, a comedian named Carlos Mencia has a great TV show, Mind of Menciaand one of my favorite segments is "Why the @#$% is this news!" where he goes about showingblatantly obvious things that were reported in various channels.
So, when I saw that IBM once again, for the third year in a row, has the fastest disk system,the IBM System Storage SAN Volume Controller (SVC), based on widely-accepted industry benchmarksrepresenting typical business workloads, I thought, "Do I really want to blog about this,and sound like a broken record, repeating my various statements of the past of how great SVC is?" It's like reminding people that IBM hashad the most US patents than any other company, every year, for the past 14 years.
(Last year, I received comments fromWoody Hutsell, VP of Texas Memory Systems,because I pointed out that their "World's Fastest Storage"® cache-only system, was not as fast as IBM's SVC.You can ready my opinions, and the various comments that ensued, hereand here. )
That all changed when EMC uber-blogger Chuck Hollis forgot his own Lessons in Marketingwhen heposted his rantDoes Anyone Take The SPC Seriously?That's like asking "Does anyone take book and movie reviews seriously?" Of course they do!In fact, if a movie doesn't make a big deal of its "Two thumbs up!" rating, you know it did not sitwill with the reviewers. It's even more critical for books. I guess this latest news from SPC reallygot under EMC's skin.
For medium and large size businesses, storage is expensive, and customers want to do as much research as possible ahead of time to make informed decisions. A lot of money is at stake, and often, once you choose a product, you are stuckwith that vendor for many years to come, sometimes paying software renewals after only 90 days, and hardware maintenance renewals after only a year when the warranty runs out.
Customers shopping for storage like the idea of a standardized test that is representative, so they can compare one vendor's claims with another. The Storage Performance Council (SPC), much like the Transaction Processing Performance Council (TPC-C) for servers, requires full disclosure of the test environment so people can see what was measured and make their own judgement on whether or not it reflects their workloads. Chuck pours scorn on SPC but I think we should point to TPC-C as a great success story and ask why he thinks the same can't happen for storage? Server performance is also a complicatedsubject, but people compare TPC-C and TPC-H benchmarks all the time.
Note:This blog post has been updated. I am retracting comments that were unfair generalizations. The next two paragraphs are different than originally posted.
Chuck states that "Anyone is free, however, to download the SPC code, lash it up to their CLARiiON, and have at it." I encourage every customer to do this with whatever disk systems they already have installed. Judge for yourself how each benchmark compares to your experience with your application workload, and consider publishing the results for the benefit of others, or at least send me the results, so that I can understand better all of these"use cases" that Chuck talks about so often. I agree that real-world performance measurements using real applications and real data are always going to be more accurate and more relevant to that particular customer. Unfortunately, there are little or no such results made public. They are noticeably absent. With thousands of customers running with storage from all the major storage vendors, as well as storage from smaller start-up companies, I would expect more performance comparison data to be readily available.
In my opinion, customers would benefit by seeing the performance results obtained by others. SPC benchmarks help to fill this void, to provide customers who have not yet purchased the equipment, and are looking for guidance of which vendors to work with, and which products to put into their consideration set.
Truth is, benchmarks are just one of the many ways to evaluate storage vendors and their products. There are also customer references, industry awards, and corporate statements of a company's financial health, strategy and vision.Like anything, it is information to weigh against other factors when making expensive decisions. And I am sure the SPC would be glad to hear of any suggestions for a third SPC-3 benchmark, if the first two don't provide you enough guidance.
So, if you are not delighted with the performance you are getting from your storage now, or would benefit by having even faster I/O, consider improving its performance by adding SAN Volume Controller. SVC is like salt or soy sauce, it makes everything taste better. IBM would be glad to help you with a try-and-buy or proof-of-concept approach, and even help you compare the performance, before and after, with whatever gear you have now. You might just be surprised how much better life is with SVC. And if, for some reason, the performance boost you experience for your unique workload is only 10-30% better with SVC, you are free to tell the world about your disappointment.
This week, I am in Taipei, teaching Top Gun class. There was concern that another typhoon would hit the island of Taiwan later this week, but it looks like it is now headed for Hong Kong instead.
Elsewhere in the world, there are several events going on next week, so I thought I would bring them to your attention.
ECTY - South Africa
Next week, Jerry Kluck, IBM Global Sales Executive for Storage Optimization and Integration Services, will be the keynote speaker at "Edge Comes to You" (ECTY) conference in South Africa. This is a one-day event, similar to the [ECTY event in Moscow, Russia] that I spoke at last June.
Here is the schedule for South Africa next week:
Monday, August 20, 2012 - Johannesburg
Wednesday, August 22, 2012 - Cape Town
(I have been to both Jo'burg and Cape Town back in 1994. A month after Apartheid had just ended, I was part of a small group of IBMers sent to re-establish IBM's business operations there. I would have liked to have attended the events next week, not just to hear Jerry speak, but also to see how much the country has changed over the past 18 years, but I could not get a work permit in time.)
If you are interested in attending either of these next week, contact your local IBM Business Partner or sales rep to attend.
Forrester's Total Economic Impact Study of Virtualized Storage
Virtualized storage can help organizations stretch their storage investment dollar and storage administration and management resources. Jon Erickson from Forrester Research will review the latest findings from IBM SAN Volume Control (SVC) users studied as part of the recently completed Forrester Total Economic Impact Study of IBM System Storage SAN Volume Controller.
Date: Tuesday, August 21, 2012
Time: 10:00 AM PDT / 1:00 PM EDT
Duration: 60 minutes
Among the findings, users were able to:
Avoid the capital cost of additional storage
Increase IT productivity
Provide greater end user data availability
The second presenter is Chris Saul, IBM Storage Virtualization Manager, who will explain how SVC can manage heterogeneous disk from a single point of control, autonomously manage tiered disk storage and can store up to five times as much data on your existing disk using IBM Real-time Compression.
Not all virtualization solutions are created equal! That's true for storage virtualization, like the SAN Volume Controller mentioned above, and it's true for server virtualization as well.
This webcast discusses the real-world impact on businesses that deploy IBM's PowerVM®
virtualization technology as compared to those using Oracle® VM for SPARC (OVM SPARC), Microsoft® Hyper-V, VMware® vSphere or other competing products.
Date: Wednesday, August 22, 2012
Time: 10:00 AM PDT / 1:00 PM EDT
Duration: 60 minutes
This webcast will include findings from a [Solitaire Interglobal] study of over 61,000 customer sites on the value of virtualization from a business perspective and how IBM's PowerVM provides real business value.
Other key discussion points that will be covered during this webcast include:
Behavioral characteristics of server virtualization technologies that were examined and analyzed from survey participant's environments
How IT colleagues were able to obtain a faster time-to-market for business initiatives when using IBM PowerVM
Why the learning curve time for PowerVM is as much as 2.58 times faster than for other offerings
Why VM reboot comparisons for PowerVM vs competitive platforms resulted in downtime of 5.5 times less than with other options
A TCO reduction of up to 71.4% for PowerVM compared to alternative options
This webcast will also feature an in-depth discussion on the IBM PowerVM solution from an IBM product expert who will share the unique virtualization features available when PowerVM is utilized within the IBM Power Systems™ environment.
Wrapping up this week's exploration on disk system performance, today I willcover the Storage Performance Council (SPC) benchmarks, and why I feel they are relevant to help customers make purchase decisions. This all started to address a comment from EMC blogger Chuck Hollis, who expressed his disappointment in IBM as follows:
You've made representations that SPC testing is somehow relevant to customers' environments, but offered nothing more than platitudes in support of that statement.
Apparently, while everyone else in the blogosphere merely states their opinions and moves on,IBM is held to a higher standard. Fair enough, we're used to that.Let's recap what we covered so far this week:
Monday, I explained how seemingly simple questions like "Which is the tallestbuilding?" or "Which is the fastest disk system?" can be steeped in controversy.
Tuesday, I explored what constitutes a disk system. While there are special storage systemsthat include HDD that offer tape-emulation, file-oriented access, or non-erasable non-rewriteable protection,it is difficult to get apples-to-apples comparisions with storage systems that don't offer these special features.I focused on the majority of general-purpose disk systems, those that are block-oriented, direct-access.
Today, I will explore ways to apply these metrics to measure and compare storageperformance.
Let's take, for example, an IBM System Storage DS8000 disk system. This has a controller thatsupports various RAID configurations, cache memory, and HDD inside one or more frames.Engineers who are testing individual components of this system might run specifictypes of I/O requests to test out the performance or validate certain processing.
100% read-hit, this means that all the I/O requests are to read data expectedto be in the cache.
100% read-miss, this means that all the I/O requests are to read data expectedNOT to be in the cache, and must go fetch the data from HDD.
100% write-hit, this means that all the I/O requests are to write data into cache.
100% write-miss, this means that all the I/O requests are to bypass the cache,and are immediately de-staged to HDD. Depending on the RAID configuration, this can result in actually reading or writing several blocks of data on HDD to satisfy thisI/O request.
Known affectionately in the industry as the "four corners" test, because you can show them on a box, with writes on the left, reads on the right,hits on the top, and misses on the bottom.Engineers are proud of these results, but these workloads do notreflect any practical production workload. At best, since all I/O requests are oneof these four types, the four corners provide an expectation range from the worst performance (most often write-missin the lower left corner)and the best performance (most often read-hit in the upper right corner) you might get with a real workload.
To understand what is needed to design a test that is more reflective of real business conditions,let's go back to yesterday's discussion of fuel economy of vehicles, with mileage measured in miles per gallon.The How Stuff Works websiteoffers the following description for the two measurements taken by the EPA:
The "city" program is designed to replicate an urban rush-hour driving experience in which the vehicle is started with the engine cold and is driven in stop-and-go traffic with frequent idling. The car or truck is driven for 11 miles and makes 23 stops over the course of 31 minutes, with an average speed of 20 mph and a top speed of 56 mph.
The "highway" program, on the other hand, is created to emulate rural and interstate freeway driving with a warmed-up engine, making no stops (both of which ensure maximum fuel economy). The vehicle is driven for 10 miles over a period of 12.5 minutes with an average speed of 48 mph and a top speed of 60 mph.
Why two different measurements? Not everyone drives in a city in stop-and-go traffic. Having only one measurement may not reflect the reality that you may travel long distances on the highway. Offering both city and highway measurements allows the consumers to decide which metric relates closer to their actual usage.
Should you expect your actual mileage to be the exact same as the standardized test?Of course not. Nobody drives exactly 11 miles in the city every morning with 23 stops along the way,or 10 miles on the highway at the exact speeds listed.The EPA's famous phrase "your mileage may vary" has been quickly adopted into popular culture's lexicon. All kinds of factors, like weather, distance, anddriving style can cause people to get better or worse mileage than thestandardized tests would estimate.
Want more accurate results that reflect your driving pattern, in specific conditions that you are most likely to drive in? You could rentdifferent vehicles for a week and drive them around yourself, keeping track of whereyou go, and how fast you drove, and how many gallons of gas you purchased, so thatyou can then repeat the process with another rental, and so on, and then use yourown findings to base your comparisons. Perhaps you find that your results are always20% worse than EPA estimates when you drive in the city, and 10% worse when you driveon the highway. Perhaps you have many mountains and hills where you drive, you drive too fast, you run the Air Conditioner too cold, or whatever.
If you did this with five or more vehicles, and ranked them best to worstfrom your own findings, and also ranked them best to worst based on the standardizedresults from the EPA, you likely will find the order to be the same. The vehiclewith the best standardized result will likely also have the best result from your ownexperience with the rental cars. The vehicle with the worst standardized result willlikely match the worst result from your rental cars.
(This will be one of my main points, that standardized estimates don't have to be accurate to beuseful in making comparisons. The comparisons and decisions you would make with estimatesare the same as you would have made with actual results, or customized estimates based on current workloads. Because the rankings are in the same order, they are relevant and useful for making decisions based on those comparisons.)
Most people shopping around for a new vehicle do not have the time or patience to do this with rental cars. Theycan use the EPA-certified standardized results to make a "ball-park" estimate on how much they will spendin gasoline per year, decide only on cars that might go a certain distancebetween two cities on a single tank of gas, or merely to provide ranking of thevehicles being considered. While mileage may not be the only metric used in making a purchase decision, it can certainly be used to help reduce your consideration setand factor in with other attributes, like number of cup-holders, or leather seats.
In this regard, the Storage Performance Council has developed two benchmarks that attempt to reflect normal business usage, similar to "City" and "Highway" driving measurements.
SPC-1 consists of a single workload designed to demonstrate the performance of a storage subsystem while performing the typical functions of business critical applications. Those applications are characterized by predominately random I/O operations and require both queries as well as update operations. Examples of those types of applications include OLTP, database operations, and mail server implementations.
SPC-2 consists of three distinct workloads designed to demonstrate the performance of a storage subsystem during the execution of business critical applications that require the large-scale, sequential movement of data. Those applications are characterized predominately by large I/Os organized into one or more concurrent sequential patterns. A description of each of the three SPC-2 workloads is listed below as well as examples of applications characterized by each workload.
Large File Processing: Applications in a wide range of fields, which require simple sequential process of one or more large files such as scientific computing and large-scale financial processing.
Large Database Queries: Applications that involve scans or joins of large relational tables, such as those performed for data mining or business intelligence.
Video on Demand: Applications that provide individualized video entertainment to a community of subscribers by drawing from a digital film library.
The SPC-2 benchmark was added when people suggested that not everyone runs OLTP anddatabase transactional update workloads, just as the "Highway" measurement was addedto address the fact that not everyone drives in the City.
If you are one of the customers out there willing to spend the time and resources to do your own performance benchmarking, either at your own data center, or with theassistance of a storage provider, I suspect most, if not all, the major vendors(including IBM, EMC and others), and perhaps even some of the smaller start-ups, would be glad to work with you.
If you want to gather performance data of your actual workloads, and use this to estimate how your performance might be with a new or different storage configuration, IBMhas tools to make these estimates, and I suspect (again) that most, if not all, of theother storage vendors have developed similar tools.
For the rest of you who are just looking to decide which storage vendors to invite on your next RFP, and which products you might like to investigate that matchthe level of performance you need for your next project or application deployment,than the SPC benchmarks might help you with this decision. If performance is importantto you, factor these benchmark comparisons with the rest of the attributes you arelooking for in a storage vendor and a storage system.
In my opinion, I feel that for some people, the SPC benchmarks provide some value in this decision making process. They are proportionally correct, in that even ifyour workload gets only a portion of the SPC estimate, that storage systems withfaster benchmarks will provide you better performance than storage systems with lower benchmark results. That is why I feel they can be relevant in makingvalid comparisons for purchase decisions.
Hopefully, I have provided enough "food for thought"on this subject to support why IBM participates in the Storage Performance Council, why the performance of the SAN Volume Controller can be compared to the performanceof other disk systems, and why we at IBM are proud of the recent benchmark results in our recent press release.

Array-based replication does have drawbacks; all externalised storage becomes dependent on the virtualising array. This makes replacement potentially complex. To date, HDS have not provided tools to seamlessly migrate away from one USP to another (as far as I am aware). In addition, there's the problem of "all your eggs in one basket"; any issue with the array (e.g. physical intervention like fire, loss of power, microcode bug etc) could result in loss of access to all of your data. Consider the upgrade scenario of moving to a higher level of code; if all data was virtualised through one array, you would want to be darn sure that both the upgrade process and the new code are going to work seamlessly...
The final option is to use fabric-based virtualisation and at the moment this means Invista and SVC. SVC is an interesting one as it isn't an array and it isn't a fabric switch, but it does effectively provide switching capabilities. Although I think SVC is a good product, there are inevitably going to be some drawbacks, most notably those similar issues to array-based virtualisation (Barry/Tony, feel free to correct me if SVC has a non-disruptive replacement path).
I would argue that the IBM System Storage SAN Volume Controller (SVC) is more like the HDS USP, and less like the Invista. Both SVC and USP provide a common look and feel to the application server, both provide additional cache to external disk, both are able to provide a consistent set of copy services.
IBM designed the SVC so that upgrades can occur non-disruptively. You can replace the hardware nodes, one node at a time, while the SVC system is up and running, without disruption to reading and writing data on virtual disk. You can upgrade the software, one node at a time, while the SVC system is up and running, without disruption to reading and writing data on virtual disk. You can upgrade the firmware on the managed disk arrays behind the SVC, again, without disruption to reading and writing data on virtual disk.
More importantly, SVC has the ultimate "un-do" feature. It is called "image mode". If for any reason you want to take a virtual disk out of SVC management, you migrate over to an "image mode" LUN, and then disconnect it from SVC. The "image mode" LUN can then be used directly, with all the file system data in tact.
I define "virtualization" as technology that makes one set of resources look and feel like a different set of resources with more desirable characteristics. For SVC, the more desirable characteristics include choice of multi-pathing driver, consistent copy services, improved performance, etc. For EMC Invista, the question is "more desirable for whom?" EMC Invista seems more designed to meet EMC's needs, not its customers. EMC profits greatly from its EMC PowerPath multi-pathing driver, and from its SRDF copy services, so it appears to have designed a virtualization offering that:
Continuesthe use of EMC Powerpath as a multi-pathing driver. SVC supports driversthat are provided at no charge to the customer, as well as those built-in to each operating system like MPIO.
and, continuesthe use of Array-based copy services like SRDF of the underlying disk. SVC providesconsistent copy services regardless of storage vendor being managed.
A post from Dan over at Architectures of Control explains the anti-social nature of public benches. City planners, in an effort to discourage homeless people from sleeping on benches in parks or sidewalks, design benches that are so uncomfortableto use, that nobody uses them. These included benches made of metal that are too hot or too cold during certainmonths, benches slanted at an angle that dump you on the ground if you lay down, or benches that have dividers sothat you must be in an upright seated position to use.
This is not a disparagement of split-path switch-based designs. Rather, EMC's specific implementation appears to be designed for it to continuevendor lock-in for its multi-pathing driver, continuevendor lock-in for its copy services when used with EMC disk, and only provide slightly improved data migration capability for heterogeneous storage environments. Other switch-based solutions, such as those from Incipient or StoreAge, had different goals in mind.
Sadly, my IBM colleague BarryW and I have probably spent more words discussing Invista than all eleven EMC bloggers combined this year. While everyone in the industry is impressed how often EMC can sell "me, too" products with an incredibly large marketing budget, EMC appears not to have set aside funds for the Invista.
If a customer could design the ideal "storage virtualization" solution that would provide them the characteristics they desire the most from storage resources, it would not be anything like an Invista. While there are pros and cons between IBM's SVC and HDS's TagmaStore offerings, the reason both IBM and HDS are the market leaders in storage virtualization is because both companies are trying to provide value to the customer, just in different ways, and with different implementations.
Earlier this week, Jon Erickson from Forrester Reserch, and Chris Saul from IBM, co-presented a webcast on the economic impact of using SAN Volume Controller for storage virtualization. The event was co-sponsored by IBM, InformationWeek, and UBM TechWeb, The Global Leader in Business Technology Media, a Division of UBM LLC. Jon spoke first, covering the cost savings and financial benefits of using SAN Volume Controller in your environment. His analysis shows a payback period of only 18 months!
Chris Saul (IBM) then covered the latest features introduced last June for SAN Volume Controller v6.4 release. Many of these features are available on older hardware models of SAN Volume Controller. One of the most exciting features is Real-time Compression.
If you missed the webcast, you can listen to the [Replay]. There is also a [whitepaper] if you prefer that format.
The Real-time Compression benefits can vary by the type of data compressed. Some data compresses only 20% savings. Other data compresses 80% or more. The best way to find out how much Compression would benefit your environment is to run the [IBM Comprestimator Tool] that runs against your own data!
If you are constantly battling out-of-space conditions, and would like to make extra room on your existing storage devices, your dreams have come true!
