In North America, today marks the start of the "Give 1 Get 1" program.
Children using the XO laptop
I first learned from this when I was reading about Timothy Ferriss' [LitLiberation project] on his [Four Hour Work Week] blog, and was surfing around for related ideas, and chanced upon this. I registered for a reminder, and it came today(the reminder, not the laptop itself).
Here's how the program works. You give $399 US dollars to the "One Laptop per Child" (OLPC)[laptop.org] organization for two laptops: One goes to a deserving child ina developing country, the second goes to you, for your own child, or to donate to a localcharity that helps children. This counts as a $199 purchase plus a $200 tax-deductible donation.For Americans, this is a [US 501(c)(3)] donation, and for Canadians and Mexicans, take advantage of the low-value of the US dollar!
If your employer matches donations, like IBM does, get them to match the $200donation for a third laptop, which goes to another child in a developing country. As for shipping, you pay only for the shipping of the one to you, each receiving country covers their own shipping. In my case, the shipping was another $24 US dollars for Arizona.No guarantees that it will arrive in time for the holidays this December, but it might.
To sweeten the deal, T-mobile throws in a year's worth of "Wi-Fi Hot Spot"that you can use for yourself, either with the XO laptop itself, or your regular laptop, iPhone, or otherWi-Fi enabled handheld device.
National Public Radio did a story last week on this:[The $100 Laptop Heads for Uganda]where they interview actor [Masi Oka], best known from the TV show ["Heroes"], who has agreed to be their spokesman.At the risk of sounding like their other spokesman, I thought I would cover the technology itself, inside the XO,and how this laptop represents IBM's concept of "Innovation that matters"!
The project was started by [Nicholas Negroponte] from [MIT University] as the "$100 laptop project". Once the final designwas worked out, it turns out it costs $188 US dollars to make, so they rounded it up to $200. This is stillan impressive price, and requires that hundreds of thousands of them be manufactured to justify ramping upthe assembly line.
Two of IBM's technology partners are behind this project. First is Advanced Micro Devices (AMD) that providesthe 433Mhz x86 processor, which is 75 percent slower than Thinkpad T60. Second is Red Hat,as this runs lean Fedora 6 version of Linux. Obviously, you couldn't have Microsoft Windows or Apple OS X, as both require significantly more resources.
The laptop is "child size", and would be considered in the [subnotebook] category. At 10" x 9" x 1.25", it is about the size of class textbook,can be carried easily in a child's backpack, or carried by itself with the integrated handle. When closed, it is sealedenough to be protected when carried in rain or dust storms. It weighs about 3.5 pounds, less than the 5.2 pounds of myThinkpad T60.
The XO is "green", not just in color, but also in energy consumption.This laptop can be powered by AC, or human power hand-crank, with workin place to get options for car-battery or solar power charging. Compared to the 20W normally consumed bytraditional laptops, the XO consumes 90 percent less, running at 2W or less. To accomplish this, there is no spinning disk inside. Instead, a 1GB FLASH drive holds 700MB of Linux, and gives you 300MB to hold your files. There isa slot for an MMC/SD flash card, and three USB 2.0 ports to connect to USB keys, printers or other remote I/O peripherals.
The XO flips around into three positions:
Standard laptop position has screen and keyboard. The water-tight keyboard comes in ten languages:International/English, Thai, Arabic, Spanish, Portuguese, West African, Urdu, Mongolian, Cyrillic, and Amharic.(I learned some Amharic, having lived five years with Ethiopians.)There does not appear be a VGA port, so don't be thinking this could be used as an alternative to project Powerpoint presentations onto a big screen.
Built-in 640x480 webcam, microphone and speakers allow the XO to be used as a communication device. Voice-over-IP (VOIP) client software, similar to Skype or [IBM Lotus Sametime], is pre-installed for this purpose.
The basic built-in communication are 802.1g (54Mbs) that you can use to surf the web usingthe Wi-Fi at your local Starbucks; and 802.1s which forms a "mesh network" with other XO laptops, and can surf theweb finding the one laptop nearby that is connected to the internet to share bandwidth. This eliminates the need to build a separate Wi-Fi hub at the school. There are USB-to-Ethernet and USB-to-Cellular converters, so that might be an alternative option.
Flipped vertically, the device can be read like a book.The screen can be changed between full-color and black-white, 200 dpi, with decent 1200x900 pixel resolution. The full-color is back-lit, and can be read in low-lighting. The black-white is not back-lit, consumes much less power, andcan be read in bright sunlight. In that regards, it is comparable to other [e-book devices], like a Cybook or Sony Reader.
Software includes a web-browser, document reader, word processor and RSS feed reader to read blogs.The OLPC identifies all of the software, libraries and interfaces they use, so that anyone that wants to developchildren software for this platform can do so.
With the keyboard flipped back, the 6" x 4.5" screen has directional controls and X/Y/A/B buttons to run games. This would make it comparable to a Nintendo DS or Playstation Portable (PSP). Again, the choice between back-lit color,or sunlight black-white screen modes apply. Some games are pre-installed.
So for $399, you could buy a Wi-Fi enabled[16GB iPod Touch] for yourself, which does much the same thing, or you can make a difference in the world.I made my donation this morning, and suggest you--my dear readers in the US, Canada and Mexico--consider doing the same.Go to [www.laptopgiving.org] for details.
"EqualLogic didn’t get 2,000 customers because people were dying to use iSCSI. It got them because it built systems that scale dynamically and because a system the size of Montana can be managed by someone as clueless as my ex-wife."
As with any acquisition, people might be asking if this is a "match made in heaven" that makes strong business sense,or another HP-Compaq debacle. Back in September, I posted [Supermarkets and Specialty Shops] to explain how the storage marketplace has two market segments. Internally, IBM distinguishesbetween "clients" and "customers". Clients are those that buy services and complete solutions from a one-stop systems vendor, such as IBM, HP, Sun, or Dell, or systems integrator like IBM, CSC or EDS. Customers are those that buy products and components, from the systems vendors I just mentioned, as well as from individual specialty shops, like EMC, HDS, or NetApp.
To reach the growing "supermarket" segment, specialty shops are dependent on systems vendors to OEM or resell their kit: EMC disk through Dell, HDS disk through Sun and HP, NetApp through IBM. Until now, EqualLogichad to make their living as a "specialty" shop, but iSCSI appeals more to SMB than large enterprises, andSMB tend to be in the "supermarket" segment, so they partnered with Sun. Here is the timeline of this likely awkwardand strained relationship:
I am not surprised that I haven't seen anything in the blogosphere yet from HP, Dell or Sun. I suspect this news meansthat Sun won't be reselling Dell's EqualLogic boxes anymore, and perhaps there is nothing more for Sun bloggers Randy Chalfant or Nigel Dessau to add to that. HP and Dell are practically non-existent in the storage blogosphere, so I didn't expect much from them either.
I did, however, expect EMC to put in their spin, given that Dell resells EMC disk, and accounts for perhaps 15% of their revenues.Now that Dell has multiple offerings, they will be instructing their channel reps when to lead with EqualLogic versus when to sell EMC, for now, until 2011, at which point may simplify their storage sales model to just EqualLogic. I don't know if Dell would do that in 2011. Depending on how quick the decline happens, EMC may have to increase the pricesof their gear, or cut into their development budgets, to make up for this loss.
I started this post because of a comment from EMC blogger Chuck Hollis, who speculates how this will impact[Dell, EqualLogic and EMC].In that post, he expresses his opinion (which I will put into a different color):
"Speculation is pretty evenly split. Neither HP nor IBM have a good, entry-level iSCSI product."
If he had left out the word "good", then that would just be a false statement, but by adding the word "good" reduces this to merely an opinion of IBM products that I disagree with. (I have no experience with whateverHP sells in this category, nor talked to any customers about their experiences, so will neither agree nordisagree with Chuck's opinion of the HP half of his statement). As for the term "Entry-level", this is fairly well defined by analysts as a storage system under $50,000 US Dollars. Actually, IBM has three good offerings.
Our basic, lowest-price model is the IBM System Storage DS3300, which does iSCSI only, like the EqualLogic offerings. This supports both SAS and SATA disks, and can attach to our System x and System p server product lines.
Our smallest model of our fancier IBM System Storage N series not only supports iSCSI, but also CIFS, NFS,HTTP, FTP, and FCP protocols, what we call "Unified Storage". The iSCSI feature is included at no additional charge, and small customers can start with this, then scale up to larger N3600, N5000 or N7000 models, andadd more protocols and software features, as their business grows.
Our next larger model, but still entry-level, is the N3600. Since the N series supports a unified multi-protocolplatform, with features like SnapLock for regulatory compliance and SnapMirror for remote disk mirroring. The IBM System Storage N series easily replaces any mix of EMC "C-boxes": Centera, Celerra, and CLARiiON.
Both the DS3300 and the N series support the various Business Applications I have discussed this week, Microsoft Exchange, Lotus Domino, SAP, Oracle, Siebel, JD Edwards and PeopleSoft. N series offers SnapManager for variousapplications to make the business value even that much better.
Chuck speculates that Dell did this to compete better against rival HP, but that doesn't make sense, sincehe feels HP didn't have much to offer in this space. Perhaps Dell did this to competebetter against IBM, the number one vendor in storage hardware, according to IDC. Looking at what IBM andNetApp have to offer, Dell may have realized that they didn't have competitive disk systems from their resellingrelationship with EMC, looked elsewhere and found EqualLogic. Meanwhile, EqualLogic probably felt that Sun wasgoing out of business, or not yet fully supportive of IP SAN environments, and decided to ["switch horses midstream"].
Continuing this week's theme on Enterprise Applications, today I will cover Oracle.
IBM is Oracle's number #1 integration partner, and has the leading market share, nearly 40 percent, for IT hardware running Oracle applications. In the coopetition category, Oracle's databases competes against IBM's DB2 database offerings, and Oracle'sapplications compete against SAP's set of Enterprise Apps. While SAP offers its own internal database, most production SAP environmentsuse either an Oracle or IBM database instead. Comparing license revenues, Oracle's application side earns roughly 70 percent of the amount SAP applications earn.
To compete against SAP, Oracle has been on a spending spree of acquisitions. This includes PeopleSoft, Siebel, Hyperion, Agile, and JD Edwards.IBM can help with all of these applications, and many clients continue to use IBM DB2 as the underlying database, rather than switching over to Oracle database. For example, IBM has sizing tools to help identify the right amount of servers and storage based on "best practice" experience.
Oracle's database uses a number-letter combination. "9i" was Version 9, "i" for Internet. "10g" and "11g" are versions 10 and 11, "g" for Grid. Most of the Oracle customers I deal with are still on 9i or 10g. The 11g releaseis supported on Linux and Windows, with the other platforms to be delivered in a staged approach.
As with SAP, it is possible with Oracle to run a front-end application on one server platform, and theback-end database on a different server platform. Many of IBM's largest customers run the front-end onAIX or Linux, and then use z/OS on System z for the back-end database.
Oracle has implemented a "Scale-Out" approach called Real Application Clusters [RAC],pronounced same as "rack", which I discussed before [Similar Sounding Storage Speech].Several servers can act as an "application cluster" to access a common database. This approachallows customers to use a bunch of x86 servers instead of a bigger System p or System i machine. Additional processor capability can simply be added into the "application cluster" as needed.
IBM and Oracle are both staunch proponents of Linux. Oracle offers theirOracle Enterprise Linux support program.In this support program, Oracle will offer support service contracts for Red Hat Enterprise Linux (RHEL) corporatecustomers.This could explain why Oracle decided to support[Linux first]on its new 11g database, rather than Windows.
To deal with all of their acquisitions, Oracle has announced its Applications Unlimited strategy. Inthis strategy, the Oracle Fusion middleware will support all of Oracle'sapplications, including JD Edwards, PeopleSoft, and Seibel. This is good for IBM, as it will simplify IBM's testing of server and storage platforms for its Oracle clients.
To support pre-sales efforts, IBM and Oracle have formed the IBM Oracle International Competency Center,[IOICC]
Continuing this week's theme on Enterprise Applications, I thought that since I mentioned Lotus Notes in my discussion ofSAP yesterday, that I would cover Microsoft Exchange today.
IBM and Microsoft is the ultimate example of "Coopetition". Both companies develop popular operating systems. Microsoft's "Xbox 360" gaming console uses IBM processors. Microsoft Exchange and IBM Lotus Domino are the Coke-and-Pepsi dominant players in the email marketplace, with Microsoft slightly in the lead, as seen on this graph[Lotus Notes/Domino marketshare growing] from fellow IBM Lotus blogger Alan Lepofsky.And now, Microsoft is getting serious about participating in the storage software business, with its strong support for iSCSI and its SharePoint product. For this post, I will focus just on email.
For those not familiar with both Microsoft and IBM products, I offer the simple cheat-sheet below:
Microsoft Outlook (client)::IBM Lotus Notes (client) Microsoft Exchange (server)::IBM Lotus Domino (server)
Email has become the primary collaboration tool for most businesses, raising it to the level of "mission-critical".Microsoft has introduced its new Exchange 2007 to replace the existing Exchange 2003. Here are the key differences:
Windows 2000 or 2003
Runs on 32-bit x86
Requires 64-bit EM64T or AMD64, but Itanium IA64 not supported
Two(2) server roles
Five(5) server roles
Edge Server Role for combating SPAM
Unified Messaging services to combine voicemail, email, fax
5 storage groups
50 storage groups per server on Enterprise edition
50 databases per server on Enterprise edition (max 5 per storage group)
NAS or NTFS-formatted block disk
NTFS-formatted block disk recommended
Obviously, Exchange only runs on Windows operating system. The change from 32-bit to 64-bit means that many Exchange 2003 customers have not yet migrated over, and perhapsnow is a good time to point out alternative email servers on more reliable operating system platforms.For example, in addition to Windows 2003, Lotus Domino runs on IBM AIX, Linux on x86, Linux on System z, Sun Solaris, i5/OS on System i, and z/OS.
Another Linux alternative to Microsoft Exchange is Bynari InsightServer, which allows you to use your existing Windows-based Microsoft Outlook clients, swapping out only the server. This approach can be used when consolidating Windows servers to Linux virtual images on System z mainframe.Linux desktops can run [Ximian Evolution] to attach to either Bynari server, or Windows-based Microsoft Exchange server.Linux Journal offers a few articles on this:[Understanding and Replacing Microsoft Exchange, andExchange Functionality for Linux].
As with [Exchange 2003 editions], the new Exchange 2007 comes in both ["Standard" and "Enterprise" editions]. With all the newroles supported, you now can limit your "Mailbox Storage Server" role as Enterprise, and have the other roles, likeEdge and Hub, as simply "Standard" instead. Enterprise is about 5x more expensive than Standard, so that can makea difference.With Exchange 2003, the big difference was that "Standard" supported only 16GB, versus 16TB with "Enterprise",making "Standard" impractical for all but the smallest company. In the new Exchange 2007, both Standard and Enterprise support 16TB.
Exchange 2007 is also less IOPS-intensive. Thanks to 64-bit addressing, it generates about 75 percent fewer IOPS than Exchange 2003 for comparable configurations. This is good becauseaccording to a 2006 Radicati Group survey, the average corporate employee gets 84 emails per day, averaging 10MBdaily ingestion, and this is expected to grow to 15.8MB daily ingestion by 2008. The number of mailboxes worldwideis growing at a rate of 16 percent per year.
IBM System Storage is a Microsoft Gold certified partner, and participates in Microsoft's Exchange Solution Reviewed Program [ESRP].Both IBM DS8000 and DS4000 series are certified under this program, using a testbed called Jetstress.Those considering IBM System Storage N series can use Exchange 2007 with NTFS-formatted LUNs via FCP or iSCSIattachment.
Backup and Business Continuity
Back in 2003, the Meta Group found that 80 percent of organizations surveyed felt access to email was more importantthan telephone service, and that 74 percent believed being without email would present a greater hardship thanlosing telephone service. These percentages are probably higher today, with websiteslike ["Crackberry.com"] to cater to those addicted to theirRIM Blackberry hand-held devices.
IBM Tivoli Storage Manager can provide backup and recovery support for Microsoft Exchange.TSM for Mail supports both Microsoft Exchange and Lotus Domino. TSM for Copy Services can use MicrosoftVolume Shadow Copy Services (VSS) interfaces. I blogged about this before, back in June[Exchange 2003 VSS Snapshot Backup Whitepaper], and now there TSM has support for Exchange 2007 as well.
Interestingly, Exchange 2007 has some built-in"Business Continuity" features. Of the ones below, Standard edition has LCR only, Enterprise edition gives you the full set.
Local Continuous Replication (LCR):In this approach, a single server ships update logs from the active storage group on one disk system over to a passivecopy on a secondary disk system, presumably within 10km FCP distance. These logs can then be forward-applied to thepassive copy. This is sometimes called "database shadowing".
Cluster Continuous Replication (CCR):This is based on two servers in an active/passive MSCS cluster. First server is attached to the primary disk system,and ships logs to the passive copy attached to the second server.
Standby Continuous Replication (SCR):For the MSCS cluster-averse customer, SCR is based on two independent servers that are in two locations. In the event of failure on thefirst, scripts can be run to switch over to the second server. Each server has its own disk system.
Single Copy Clusters (SCC):This is for customers who have existing systems, but not recommended for new customers. An MSCS cluster, where both active andpassive servers are connected to the same single disk system. The disk array can be a single point of failure (SPOF) in this environment.You could mitigate risks by using IBM's disk mirroring in this situation, but then you are left coordinating those copies with new servers at the remote location.
It is estimated that as much as 75 percent of a company's intellectual property (IP) can be found somewhere in their email repository. Email is often requested in lawsuits and regulatory investigations. According to the Workplaceemail IM & blogging 2006 survey by AMA and the ePolicy Institute, 24 percent of organizations have be subpoenaed by courts and regulators, and another 15 percent have gone to court in lawsuits triggered by employee emails.
New regulations now mandate that emails are archived, protected against tampering and unauthorized access, and kept for a specific amount of time, or until certain conditions are met. According to a 2004 CSI and FBI Computer Crime and Security survey, 78 percent of organizations were hit by viruses (the rest must have been running Linux, AIX, i5/OS or z/OS!)and 37 percent reported unauthorized access to confidential information.
According to Gartner, over 60 million people will be doing some form of telecommuting, so access Microsoft hasbeen working on extending the reach of email beyond Outlook client. There is now "Outlook Web Access" thatprovides browser-based access, "Outlook Mobile" to provide text access from cellular phones, and even "Outlook Voice Access" which allows you to listen to your emails from any phone. These are all part of the new Unified MessagingServices feature.
Continuing this week's theme on Enterprise Applications, I will talk about [SAP] today.
The history of SAP is fascinating. Back in 1972, five IBMers noticed that IBM wasn't leveragingits internal accounting/inventory software package. They asked if they could buy the rights to it, leave IBM to form their own company to fix it up, and sell it as their own. Since IBM had decided not tobe in the enterprise applications business any longer, they approved. These guys renamed the software to "Realtime Data Processing/1" or just R/1 for short, andformed Systemanalyse und Programmentwicklung AG. In 2005, they renamed this to Systeme, Anwendungen, Produkte in der Datenverarbeitung AG,which is German for "Systems, Applications, and Products in Data Processing, Inc.", withSAP AG as the preferred abbeviation (the AG here is justthe German version of "Inc.").
R/1 became R/2, then R/3, and today is now called the SAP ERP forthe SAP Business Suite, although many still call it R/3. Other popular Business Suite components includeCustomer Relationship Management(CRM), Product Lifecycle Management (PLM), and Supply Chain Management (SCM),and Supplier Relationship Manager (SRM).The architecture had evolved in this time frame, separating out the application components from a base platform product line called NetWeaver, similar to IBM WebSphere Application Server (WAS). Other ISVs or in-house developers can build their applications directlyonto the NetWeaver base platform, creating a form of eco-system of software applications.
Today, SAP is now the fourth largest software company (behind Microsoft, IBM and Oracle) employing over 42,000 employees worldwide,and is considered the leading global vendor of Enterprise Application software, generating over $14 billiondollars in revenue each year.
SAP runs on all of IBM's major operating systems and server platforms, so it makes sense for IBM to continue its strong ties to SAP. Together, we formed the IBM SAP International Competency Center[ISICC], in Waldorf, Germany,where SAP has its headquarters. I have been to Germany and visited with the folks from the ISICC.Of my 17 U.S. patents, several were for a feature called z/OS DFSMShsm "Fast Replication" that was requested by SAPat one of these meetings. This featuretakes advantage of IBM System Storage DS8000 FlashCopy to make instantaneous backups of an SAP environment built on DB2 for z/OS databases. For more details read the [IBM Redbook: Fast Replication].
The #1 UNIX platform for SAP is IBM's AIX operating system that runs on System p servers. Some of our customers create a[Composite Application] by havingthe SAP front-end application server run on AIX, and use z/OS to host the SAP DB2 databases. Thisallows you to take advantage of DFSMShsm Fast Replication on System z, with the number-crunching power of theSystem p server.
What's most exciting to me about SAP is that for every dollar spend on IT hardware to support an SAP application,60% is for storage, and 40% for servers. Therefore, buying both from IBM is simpler and easier than shoppingfor these separately.
IBM Tivoli Storage Manager (TSM) was the first product to certify to SAP's BC-BRS interface for copy/mirror/backup/restore. IBM provides additional support with TSM for SAP, TSM for Databases, andTSM for Advanced Copy Services (ACS). TSM for ACS supports the use of FlashCopy on SVC, DS8000, DS6000, and ESS; as well as SnapShot on the IBM System Storage N series.
IBM's recent push into the Archive and Compliance space offers[IBM CommonStore for SAP],which acts as an "archive file manager" between you SAP application and your archive repository, such asthe IBM System Storage DR550, DR550 Express, N series, and tape.
What's Next: SMB and SaaS
Since SAP has saturated the market for medium and large size businesses, IBM is now focused on helping theSMB customer base. The majority of these are expected to deploy SAP on x86 platforms running Linux orWindows. For smaller companies, SAP has their "Business All-in-One" for companies with 100-500 users,and "Business One" for companies with less than 100 users. Note: not every employee may need to use SAP,so larger companies may have only a subset of their employees actually using the SAP system and find thesesmaller offerings a good fit.
Nicholas Carr on his Rough Type blog writes:[has SAP unleashed a cannibal?],referring to SAP's new "Business ByDesign" Software as a Service (SaaS) offering to compete againstSalesforce.com business model. Rather than installing and maintaining the SAP software yourself, youinstead pay SAP on a per-user/per-month basis to use their systems remotely. The reference to cannibalism comes from the IT slang "eat your ownchildren", the notion that IT companies may introduce a new offering that eats away at future sales of theexisting product set.

I am in Toronto, Canada. It is a lot cold and rainy here, worse than last week in Seoul, Korea.This looks like a slow news week, so slow that the only news here in Canada is the possibility of anew 5-dollar coin. I thought I would make this week's theme about enterprise applications.
IBM doesn't make these applications anymore, we have decided to focus on our core strength, to be the best IT platform to run other people's applications. This means being the best IT systems, software and services company. However, many of the companies that make enterprise applications are both cooperate and compete against parts of IBM, what we call "coopetition".
Let's take a look at some acronyms in this space:
"Enterprise Resource Planning" represents all the basic applications that business need to run theirbusiness, including: finance, accounting, human resources, and manufacturing. The focus here is to streamline operations and make the workforce more productive. Before IBM, I ran my ownsoftware development company, Pearson Kurath Systems, and we developed ERP applications for clients oneby one, customized to their industry requirements.
"Customer Relationship Management" or sometimes "Client Relationship Management" help companies identifyand retain their customer base. Focus here is to increase customer satisfaction and loyalty.
"Supply Chain Management" help track supply and just-in-time inventory demand, sharing the information withkey suppliers and distributors. The focus is to manage inventories down to nothing, and improve speed to get products out to market.
"Business to Business" refer to procurement, purchase orders, and collecting payments over the internet.One of my pet peeves are acronyms that use "2" to mean "to" and "4" to mean "for".
"Human Capital Management" deals with managing costs of Human Resources (HR) and coordinating servicesfrom outside organizations.
"Knowledge Management" refers to sharing and collaborating information. This is not just email and instant messaging, but also online calendaring, experience repositories, client case studies, and anecdotes.
This week I will cover applications that address these, and how they relate to storage.
IBM announced the industry's first corporate-led initiative to enable clients to earn energy efficiency certificates for reducing the energy needed to run their data centers.For the first time, this provides a way for businesses to attain a certified measurement of their energy use reduction, a key, emerging business metric. The certificates can be traded for cash on the growing energy efficiency certificate market or otherwise retained to demonstrate reductions in energy use and associated CO2 emissions. The Efficiency Certificates initiative engages Neuwing Energy Ventures, a leading verifier of energy efficiency projects and marketer of energy efficiency certificates.
How it works:
The Neuwing Energy assessments are a two-part evaluation to 1) determine the initial energy draw from the data center or IT equipment identified for consolidation based on industry accepted energy estimates for the servers in use and the power and cooling profiles of the data center, and 2) a second review of energy draw after steps are taken that are designed to reduce energy consumption.
Neuwing Energy will issue customers an Efficiency Certificate for the total megawatt-hours of energy no longer needed to power and cool their data center or operate IT equipment. Neuwing Energy will keep a portion of each customer's earned certificates or charge a per MWH saved fee in exchange for the assessment.
Customers can trade earned Efficiency Certificates on the energy efficiency certificate market or they can retain their certificates, using them to demonstrate reductions in energy use and associated CO2 emissions.
IBM intends to make the Efficiency Certificates program available across its entire line of server and storage offerings.
In this case, it is not chess pieces, but FUD being slung around like mud between vendors. EMC blogger Chuck Hollis' post [Products vs. Features] correctly pointsout that IBM has invented most nearly everything useful in IT, and sadly a few things we wish we hadn't.Gene Amdahl, who left IBM to start his own company, is credited for coining the phrase describing IBM'sinnovative sales techniques. Wikipedia has a nice write up on the history of[Fear, Uncertainty and Doubt(FUD)].
Nowadays, when you hear "FUD" most storage administrators immediately think of EMC, who have taken this method to anew level of art-form. Take for example two EMC entries from fellow blogger BarryB, on his Storage Anarchist blog:[Not Dead Yet, andPushing Daisies].The first is a reference to a funny scene from a Monty Python movie, and the second one is referring to a terriblenew television program called "Pushing Daisies". (In this show, the main character can bring a dead personback to life for sixty seconds, just long enough to ask a few questions on behalf of his detective friend. He must touch the person again within 60 seconds, or someone else randomly dies instead. I amnot a fan of this concept, and found it a bit morbid and creepy. But I digress.)
It is true I was on vacation the past two weeks, but this was group travel I booked over six months ago before we had the exact dates lined up for our various announcements, and not a last-minute celebration of my recent new job assignment. I got all my assignments for this announcement turned in before leaving for my trip. I never thought of checking with fellow IBM blogger BarryW to make sure that we don't have overlapping vacation schedules, leaving the "blogosphere" unmanned, so to speak, but it is not a bad idea. Fortunately, our IBM PR team was able to make their rebuttal through other means. You can read the recap on Techworld [Marketing Wars by Proxy].
Several astute readers on my blog, however, requested that I add my two cents. Let's take a look at some of BarryB's comments:
...most DS8300's are to this day most frequently bundled as "free" storage with IBM mainframe and server sales.
We just shipped our 15,000th box, so for this absurd statement to be true, more than half would have to be given away as part of a server-and-storage deal?Actually, about a third of our DS8000 sales are sold with servers in the same bundle, and while we do provide discounts from the official list price, that is not the same as "free". The other two thirds are sold into accounts to be used with the existing servers already deployed. So BarryB, your math doesn't work out. (Perhaps you've been taking Hitachi math lessons???)
It is interesting however, that when we do a 4-year TCO comparison, between a normally-discounted DS8000 versus free EMC DMX4 hardware, IBM still has the lower cost, given that most of the price-gouging from EMC happens after the initial sale, through software features, annual Powerpath renewals and MES upgrades. If you are an EMC customer, and you are planning to add more capacity to your DMX, ask EMC to charge you no more than what you originally paid on a dollar-per-GB basis for the initial capacity. That's only fair, right?
...No thin provisioning, or even a commitment to thin provisioning. Just crickets. (Celerra support since Jan 2006...
EMC DMX does not have thin provisioning available today either, so BarryB brings up Celerra, their NAS box? IBM System Storage N series NAS box also has thin provisioning, so if you want thin provisioning you can buy a NAS box from EMC or IBM. Thin provisioning makes sense using NAS protocols, as there are actual commands to "delete a file" that can then free up the related blocks in a thin-provisioned environment. The only way to do this with block-oriented protocols is to get the OS to notify the storage device that blocks can be freed up. As it turns out, IBM's z/OS has such support, which we developed specifically for our thin-provisioning support in our IBM RAMAC Virtual Array disk systems back in the 1990s.For block-oriented devices on most other operating systems, thin provisioning may not be all that it is cracked up to be.
No SATA drives (only DMX-4 supports native SATA-II drives, since Aug’07)
A few people are confused on this. IBM DS8000 has supported FATA for quite some time now, same slower speeds and higher capacities as SATA, but are technically NOT the same as SATA. FATA are designed to provide better protection against vibrational shock, to improve reliability of the drives. IBM felt that if the data was important enough to put on a high-end system, it should get better-than-SATA treatment. If you really want SATA, try our IBM System Storage N series, DS4000 or DS3000 models.
No RAID 6 (DMX-3 has supported multi-dimensional RAID since Q1’07, DMX-4 since Aug'07, ...
IBM N series supports RAID6, but we called it RAID-DP and that confused some people. Same thing, DP stands for Dual Parity, protecting against a double-disk failure. We also just announced RAID6 on our DS4000 series, by the way.
No 4Gb back-end (USP-V since May '07, DMX-4 since Aug’07)
I found this one odd, since BarryB himself in an earlier post explained why 4Gbps back-end made no difference to DMX4 performance in this post [DMX-4 and Oh So Much More], which I will put into a different color so you can tell it is from a different post:
You may have noticed that there weren't any specific performance claims attributed to the new 4Gb FC back-end. This wasn't an oversight, it is in fact intentional. The reality is that when it comes to massive-cache storage architectures, there really isn't that much of a difference between 2Gb/s transfer speeds and 4Gb/s. Transmit times are really only a tiny portion of I/O overhead, and just don't make that much difference when a massively-cached system is pre-fetching reads, buffering/delaying writes and reordering I/O requests to minimize seek times. Not that 4Gb/s won't help some applications, but most people just won't see any noticeable difference.
In this case, BarryB is right. The IBM DS8000's 2Gbps back-end is not a performance bottleneck. The DS8000 with a 2Gbps back-end is faster than DMX4 with a 4Gbps back-end for business application workloads. EMC doesn't publish SPC benchmarks to deny this, so you will just have to take our word on this.
Still only 1024 maximum disk drives (DMX-3 & 4 support up to 2400 drives, USP-V supports 1152)
I would be curious to see how many customers have more than 1024 drives on any high-end disk array.As we learned back in [Day 2 Storage Symposium], the average DS8100 has 17.4 TB, and DS8300 has 41.5 TB capacity. Using 500GB drives,that's only 83 spindles. Even with 73GB drives, that's 568 spindles. Plenty of room for growth, so I am notconvinced that higher theoretical upper architectural limits are worth discussing here.
Still only two HARD LPARs (partitions) ..., and even IBM’s mid-tier products support more than 2 storage partitions (in this same announcement)
IBM's two LPARs are TWICE what EMC DMX offers. I don't even know why anyone from EMC would bring this up? While EMC is enjoying their success with VMware, the lack the experience to carry this over to their storage lines. Until EMC offers MORE THAN TWO of any kind of partitions on their high-end offerings, there just is no credibility here. As for our "storage partitions" on our DS4000 line, that is an unfortunate mis-understanding of the press release. On the DS4000, the term "storage partition" is really "LUN masking", dividing up only which disks can be accessed by which hosts, and not dividing up any processor or cache capacity. So this is not the same as any LPAR concept on any other system. For example, a DS4000 with 64 partitions can be attached to 64 hosts, or 64 host-clusters like a Windows MSCS environment or AIX HACMP.
No native Ethernet replication or iSCSI support (Symmetrix has had since 2002)
Again, I found this one odd. On another EMC post, [Vigorous Debates],Chad Sakac mentions that only 2% of Symmetrix are sold with IP ports, not sure if this is for Ethernet replication, iSCSI attachment, or both (Again, I will use a different color):
On the Symm business (a huge part of EMC’s business – the IP ports are included on 2% of deals. That’s a fact.
Just because engineer can put a feature or function on a box, doesn't mean there is business sense to do so. I would hate for IBM to invest millions of dollars on native iSCSI support, only to have 2% of our DS8000 boxes sold with that feature. Customers who have DS8000 on FC SANs already deployed can easily add iSCSI support either through their SAN switches, or by fronting the DS8000 with an N series gateway. Most customers looking for native iSCSI are the smaller no-SAN-deployed SMB customers, and for them, we have both the DS3300 and the various N series models to choose from.
Well that's my two cents. The DS8000 series remains a strategic part of the IBM System Storage offering matrix, with continued investment in the development, as well as on-going research that we can leverage throughout the IBM company. I would like to read your thoughts on this, post me a comment below.
Well, it is Halloween back in the USA. I am in Seoul Korea this week, so it is already Thursday, November 1st here, but thought I would comment on Colin Barker's piece in ZDnet titled[SNW offers the frights].The article starts out with an oversimplification:
The storage industry is enjoying a boom currently thanks to the requirement for IT managers to keep everything. With the possibility of being sued any time by any company for no good reason at all, everyone is keeping everything, or at least all their data. Result? Loads and loads more kit being bought to the benefit of EMC, IBM, HP and every other supplier with any kind of storage product.
While its true that IBM System Storage grew yet again in 3Q07, exceeding our own internal business model, I would not call this an overall "boom" for the storage industry. While companies are growing in "TB capacity" by 30-50%, this translates only to single digit growth in terms of "Dollar revenues". This is because we continue to make storage with declining dollar-per-GB.
One should not confuse what people do with what people are required to do. I am not a lawyer, but most regulations pertaining to storage of information state that certain records need to be kept for a set amount of time, either a fixed period of years, or based on some event. For example, broker/dealers need to keep emails of their clients for six years after the client closes their brokerage account. After those six years, the records can be destroyed.
Unfortunately, many IT managers look at the laws and come up with the simplest solution: keep everything forever. While this might meet the regulators audit requirements, it does expose their employer to subpoenas for data that should have been deleted, and may not be very cost-effective.
The alternative for many IT managers involves having to leave their comfort zone, and talk to their legal counsel, the lines of business, and try to classify their data, determine a set of policies, and inact some forms of enforcement. This is perhaps the "scary" part of the storage of information, it has grown outside the walls of IT, forcing IT managers to interact with the rest of the business to get their jobs done.
Compliance is the only game in town and that is most certainly where the money is.
Anytime an analyst tells you that something is the "only game in town", they are usually wrong. In this case, IBM has had great success in other areas that are not compliance-related. For example, digital video surveillance (DVS) is being used not only to help reduce shoplifting, but also to help identify patterns in customers perusing through aisles and window-shopping. Identifying what people are interested in has proven effective in moving product displays around to better attract buyers and motivate them to make purchases.
Take, the keynote from Andy Monshaw, general manager of IBM storage, and thus a man who is very much in a position to know. He spent his allotted 30 minutes, or whatever, listing all the security, compliance, threats and related issues that are currently making the jobs of most IT manager a cause for concern. Now, there is an argument that suggests that it is absolutely the right thing to do to frighten IT managers into sorting out their issues. They need shaking up say some. Especially analysts.
I helped develop the content of Andy's SNW presentation, working with his speech writers and graphic artists to make a consistent and coherent message fit in the 25 minutes he was given. The challenge with SNW is that we needed to make this presentation applicable across the entire storage industry, without sounding like an infomercial for IBM offerings.
Some people have compared the storage to the "insurance industry", claiming that backups, remote disk mirroring, continuous data protection and other storage related features are costs that can be compared to insurance you pay to protect your home, business, and other assets. You hope you never have to use it, and complain how much it costs, but when bad things happen, you hope it is the best money can buy.
Unlike Y2K, which was a one-time event that had a specific date of occurrence, the threats and risks mentioned by Andy in his presentation may never happen at all, or in other cases, may happen more than once, without knowing when or where. For the sake of your shareholders, and your stakeholders, it is best to be prepared for these possibilities.
The counter argument says that IT companies just smell the money.
Is this a counter argument? Can IBM not both help customers mitigate their risks, and at the same time, turn a profit? Trust me, you do not want to do business with any storage vendor that is not interested in making a profit. The better ones have incorporated addressing client's most pressing challenges into their strategy. I gave a quick summary of IBM's strategy last August in [Day 1 Storage Symposium].
Helping our clients mitigate risks is just one of IBM's core strengths. If you want to learn more, contact your local IBM Business Partner or storage rep.
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.
Well, I'm back from my relaxing vacation in New Zealand and Fiji. Yes, we hada few earthquakes near Milford Sound, several avalanches that blocked some roads, a few power outages, and we walked in a rain storm for three hours after our bus broke down. But overall, it was fun.
This week I am in Seoul, South Korea for various business meetings. The best part is that I am almost already acclimated to the time zone, since New Zealand was GMT+11 and Fijiwas GMT+12, I am hoping that I will adjust fast this week.
South Korea is part of our "BRICK" countries--those emerging markets made up of Brazil,Russia, India, China and Korea that represent IBM's spearhead into the SMB marketplace.[Read More]
Two European scientists, Albert Fert (France) and Peter Grunberg (Germany) have won the 2007 Nobel Prize for physics for their research into Giant Magnetoresistance, or GMR. GMR read/write heads are used in IBM disk systems.
New high-density dual-coated particulate magnetic tape: Developed by Fuji Photo Film Co., Ltd., in Japan in collaboration with IBM Almaden researchers, this next-generation version of its NANOCUBIC™ tape uses a new barium-ferrite magnetic media that enables high-density data recording without using expensive metal sputtering or evaporation coating methods.
More sensitive read-write head: For the first time, magnetic tape technology employs the sensitive giant-magnetoresistive (GMR) head materials and structures used to sense very small magnetic fields in hard disk drives.
GMR servo reader: New GMR servo-reading elements, software and fast-and-precise positioning devices provides an active feedback system with unprecedented 0.35-micron accuracy in monitoring and positioning the read-write head over the 1.5-micron-wide residual data track.
Improved tape-handling features: Flangeless, grooved rollers permit smoother high-speed passage of the tape, which also enhances the ability of the head to write and read high-density data.
Innovative signal processing algorithms for the read data channel: An advanced read channel used new "noise-predictive, maximum-likelihood" (NPML) software developed at IBM's Zurich Research Laboratory to process the captured data faster and more accurately than would have been possible with existing methods.
IBM often leverages the research done in one part of its business over to other parts of its business. In this manner, advances in disk translate into advances in tape, keeping tape a viable medium for at least the next 8-10 years.
This is great news for everyone. I have said before that VMware is perhaps the best product EMC offers, and some EMC bloggers have returned the favor saying that SVC might just be the best disk system that IBM offers. While IBM and EMCare heavily competitive in other aspects of the IT storage industry, when it comes to delivering what is right for the customer, we can set aside those differences. IBM is the number one reseller of VMware, and it is a great pairing with SAN Volume Controller.
Of course, it is not a free-for-all. VMware has a few restrictions at this time:
The VMware certification is limited to Windows operating system, specifically those listed on its [Guest OS Guide].The list looks fairly extensive, so if you were running Windows guests on VMware to SVC today via RPQ,you are probably covered. However, if you are running NetWare or Linux, then the VMware certification doesnot yet apply.
host bus adapters
Only Qlogic host bus adapters are supported at this time. This is because VMware directly communicates to the host bus adapters as part of its "I/O virtualization" capabilities, and needs to work with or test with all the other HBA manufacturers.
no RDM support
Raw Device Mapping (RDM) mode is currently not yet supported. This probably will only affect a small percentage of customers, as I don't know of any major applications that require this.
Of course, most of these issues can probably be addressed with additional testing, or minor software changes, and IBM will work with VMware to prioritize what added testing or software changes are needed to expand this support.
I am Tony Pearson, storage consultant at the IBM Executive Briefing Center, located in Tucson, Arizona. I have degrees in Computer Engineering and Electrical Engineering from the University of Arizona. Over the past 20 years, I have worked in a variety of storage roles, including development projects, product and portfolio management, testing, field support, marketing, and now am doing storage consulting.
There are a lot of things to discuss related to storage, and I am never short of opinions. As such, the standard IBM disclaimer applies: “The postings on this site solely reflect the personal views of the author and do not necessarily represent the views, positions, strategies or opinions of IBM or IBM management.”
I have invited other IBMers to post their opinions, and when they do, their opinions may not necessarily match mine either.
This is an open two-way conversation between IBM, Business Partners, Independent Software Vendors, prospect and existing clients. I encourage everyone to post comments about our products, services, and marketing efforts.
I welcome HDS into the "Super High-End" club. Those who follow my blog might remember thatI suggested that analysts like IDC that use "Entry Level", "Midrange" and "Enterprise" as categoriesmay need a New Category: Super High End.
I was not surprised to see EMC, who now drops further down in perception, dispute HDS's recent SPC-1 benchmarks.Fellow blogger EMC's BarryB posted on his Storage Anarchist blog [IBM vs. Hitachi] thatpoints out that IBM's SAN Volume Controller (SVC) is still much faster, and less expensive, than USP-V.
So, just in case you haven't seen all the press releases, here is a quick recap on the results:IBM SVC 4.2 is still in first place, then HDS USP-V, then IBM System Storage DS8300. Just for comparison, I includeour IBM System Storage DS4800 midrange disk results, so you can appreciate the difference between midrange and high-end.There are other products from other vendors, I just point out a few from IBM and HDS here in this graph.
******************************************************************** 272,505 IOPS - IBM SVC 4.2 ************************************************** 200,245 IOPS - HDS USP-V ******************************* 123,033 IOPS - IBM DS8300 *********** 45,014 IBM DS4800
HDS tried to come up with a phrase "Enterprise Storage System" for comparison that would leave the SVC 4.2 out.Given that the SVC has five nines (99.999%) availability, has non-disruptive upgrade and firmware update capability, has more than two processors typical of midrange products, and can connect to mainframes via z/VM, z/VSE andLinux on System z operating systems, there is no reason to pretend SVC isn't Enterprise-class.
The irony now is that EMC now looks very lonely being one of the last remaining major storage vendors not to participate in standardized benchmarks that help customers make purchase decisions, as mentioned both by IBM's BarryW: I guess that only leaves EMC, as well as HDS's Claus Mikkelsen: Olympics of Storage.
Earlier this year, EMC's Chuck Hollis opined[Storage Scorecard]that the EMC DMX and HDS TagmaStore USP were high-endboxes, which I would speculate both of these would fall somewhere between DS4800 and DS8300 on the graph above.If that is the case, it is impressive that HDS was able to re-engineer their USP-V to be 2-3x faster thanits predecessor, the USP.
Not all workloads are the same, and your mileage may vary. While I can't speak to HDS, the folks over atEMC have assured me, in writingcomments on this blog, that there is nothing preventing their customers from publishingtheir own performance comparisons between EMC and non-EMC equipment. I would encourage every customer to do this, between IBM and HDS, HDS and EMC, and between IBM and EMC, to help shed even more light on this area.In fact, you can even run your own SPC benchmarks to see how your own environment compares to the ones published.
Of course, performance is just one attribute on which to choose a storage vendor, and to choose specific products,models or features. For more information about Storage Performance Council and the SPC-1 and SPC-2 benchmarks,see my week-long series on SPC benchmarks, which are listed in reverse chronological order.
Go to the official Storage Performance Council website to read the details of the SPC-1 results.
Today, 13.5% of EMC's sales force is female, the company says, compared with 40% at International Business Machines Corp. and 29% at CA Inc., a big software vendor, those companies say. According to the 2000 U.S. census, about 25% of high-tech employees nationally were women.
IBM recognizes that diversity provides unique advantages in dealing with a global marketplace. Not only are women well represented on our IT sales force, they are also well represented on our board of directors, our Worldwide Management Committee, and our executive team overall, as well as in technical positions such as IBM Fellows, Distinguished Engineers, members of the IBM Academy of Technology. Working Mother magazine has rated IBM one of the top 10 "Best Companies" for women to work for in each of the 18 years that it has published this list.
In 2006, 51 camps called EXITE (Exploring Interests in Technology and Engineering) were held worldwide in 33 countries. The hope is to get young girls to pursue college degrees in computer science, math and engineering, so that they can then help fill the shortage of technical resources in IT.
So, if you are a women discouraged at your current place of employment, and are looking for exciting new opportunities in IT, come check out working for IBM![Read More]
Over the past year and a half, I have been focused on explaining WHAT IBM System Storage was, and WHY IBM should be considered when making a storage purchase decision. Let's recapsome of IBM's accomplishments during this time:
Today, October 1, I switch over to HOW to get it done. In my new job role, I will be leading a seriesof projects and workshops on how to make your data center more green, how to get more value from the information you have, how to better protect your information from unauthorized access or unethical tampering, how to develop and deploya site-wide business continuity plan, and how to centralize your management using open industry standards.
I will still be in Tucson, but am moving from building 9032 over to 9070 to be closer to the rest of my team.
I was in Raleigh this week, in business meetings, and had dinner last night at a Japanese Tepanyaki restaurant. The man next to me was dining alone, and said he worked for Cisco, a big company, "Had you heard of it?" he asked. Of course, I told him, I work for IBM, and IBM and Cisco have a strong working relationship, using each others products in both directions. He said he understood why they would use IBM, but why would IBM buy anything from them, and then he said, "Oh yes, your cafeteria".
At this point we realized he was talking about SYSCO, the food company, not Cisco, the storage networking technology partner. We both had a good laugh.
Which brings me to think of other "mis-heard" or "mis-interpreted" items that might have caught people off guard because they sounded similarly.
zFS versus ZFS
Some things are case-sensitive. Lower case zFS is the hierarchical file system for the z/OS mainframe environment, which was originally called "episode" file system that IBM acquired from TransArc. z/OS supports two file systems, HFS and zFS. Meanwhile, ZFS is one of the file systems available for Sun Solaris. Apple Mac OS is switching from its own HFS, different than the z/OS version, over the Sun's ZFS.
packs versus PACS
Older mainframers call disk volumes "packs". This started in the days where disks were "removable" and you can pack and unpack them into the drive unit.
PACS on the other hand refers to the "Picture Archive and Communication System" application environment used by hospitals and medical facilities to storage and share X-ray, Cardiology and Radiology images. Today, modern medical equipment are called "modalities" and directly connect to NAS storage via NFS or CIFS protocols. The images are immediately digitized and sent to disk, then tape, for long-term archive storage. IBM's Grid Medical Archive Solution (GMAS) is designed specifically for this environment.
rack versus RAC
Perhaps my favorite was when someone asked a high-level executive at a conference if their storage product supported Oracle RAC, and the response was that it supported anyone's rack, so long as it met the 19 inch standard. Everyone burst out laughing, and he probably had to be explained what was going on afterward.
Oracle RAC refers to Real Application Cluster, allowing multiple Oracle servers to work together as a system. A "rack" is just the powered shelf, typically 19" wide, and typically 25U or 42U tall, that allows modular servers, storage or network gear be placed together in a data center. A "U" is 1.75 inches, the thickness of a "two-by-four" piece of lumber. If you have ever used a 3.5 inch or 5.25 inch floppy diskette, then you already know the 2U and 3U sizes.
I am sure there are many other examples of similar sounding terms and phrases. If you have any to contribute, post a comment below!
Guy Kawasaki is hosting a Web Conference next week on The Art of Evangelism.By this he is referring to promoting products and services, rather than the traditionaldefinition: the preaching or promulgation of the gospel.
A few years ago, I myself had the official title of "Technical Evangelist" for the IBM System Storageproduct line. I never liked the title, and asked to use something else, but since I was part of ateam of "Technical Evangelists," I had to keep it. A lot of companies were using this as a title,I was told, and everyone knew that it was not a religious reference, but a marketing one.
Sometimes, words do not translate well into other countries or cultures. Four years ago, on theweek of September 11, 2003, I traveled to Kuwait, Qatar and UAE for a business trip to present thelatest on our storage products. On arrival in Kuwait, I had to fill out my "visa application" to enterthe country, and it asked for my "occupation/title" but there were not enough spaces to write "Technical Evangelist" so I just entered "Evangelist".
The two Kuwaitis behind the desk looked it up in their Arabic/English dictionary, discussed it, andweren't sure if they should shoot me, or take me to the back room to video tape my proper be-heading. Our official hostcame over to ask what was the delay, and they showed her the dictionary translation. She asked me,"Why would you put Evangelist as your title?" So, I gave her my business card, and told herthat my full title of Technical Evangelist did not fit in the space provided.
She explained to the two behind the desk that I had misunderstood the question, and misspelled theactual word intended was "Engineer". She showed them the agenda of the IBM Technical Conference I wasspeaking at, and the list of Oil and Construction companies that were attending. They looked upthe new title "Engineer", and agreed the translation was suitable for entry, and that these two words,Evangelist and Engineer, used enough similar letters they could understand how one might misspell one for the other.
Our limo took a small detour to the middle of the desert so that we could burn and bury the ashes of the remainder of my business cards, before arriving to the hotel. All of my powerpoint slides that listed my title were changed to "Technical Engineer". The events themselves went very well,as IT people are the same all over the world, and had no problem setting aside religious or politicaldifferences in an effort to learn more about technology.
When I got back to the United States, I shared my experience with my fellow team-mates, most of whom never leavethe country, and would never have thought this might happen. Management agreed to let us change our titles.That was good for me, as I had to order a new box of business cards anyways.
Last year, I became "Manager of Brand Marketing Strategy" of the IBM System Storage product line.Now on business trips I just write "Manager" on the Occupation/Title line. It fits in every form I have ever had to fill, and translates properly into every language.
Today I spoke at the IBM Think Green Roadshow in Phoenix, Arizona. This is justone of a 15-city tour to help make people aware of Green data center issues.Here is the schedule forthe remaining cities. Contact your local IBM rep for details.
Victor Ferreira was our moderator and host. He is the site level executive for the2000 IBM employees in the Phoenix area, and manages the Public Sector for our Westernregion.
The first speaker was Dave McCoy, IBM principal in our Data Center services group.He explained IBM's Project Big Green and the Energy Efficiency Initiative, and wentinto details on how IBM can act as general contractor to design, plan and build theideal Green Data Center for you. IBM can also retrofit existing buildings, with new technologies like stored cooling, optimized airflow assessments, and modulardata center floorspace. While not related to energy, but still important to ourenvironment was IBM Asset Recovery Services, where IBM can take all those old PCmonitors, keyboards and other outdated equipment and refurbish or melt down to recapture useful metals and plastics, and disposing the rest in an environmentally-friendly,non-toxic manner.
I was the second speaker, covering "How to get it done". While Dave covered the issuesand technologies available, I explained how to put it all into practice. This includesIT systems assessments, health audits, and thermal profiling. Using server and storagevirtualization, you can increase resource utilization and reduce energy waste. IBM's CoolBlueproduct line, which includes the IBM PowerExecutive software to monitor your IT environment, and the "Rear Door Heat Exchanger" that uses chilled water to remove asmuch as 60% of the heat coming out of the back of a server rack, greatly reducing hot-spotson the data center floor, and allowing you to run the entire room at warmer, less-expensivetemperatures.
On the server side, I covered IBM's System z mainframe and the BladeCenter as examples of how innovative technologies can be used to run more applications with less energy. The newSystem p570 based on the energy-intelligent POWER6 processor has twice the performance for the same amountof power as its POWER5 predecessor. On thestorage side, I explained how Information Lifecycle Management (ILM), storage virtualization,and the use of a blended disk and tape environment can greatly reduce energy costs.
Reps from our many technology partners Eaton, APC, Schneider Electric, Liebert, and Anixter werethere to support this event.
The session ended with a Q&A Panel, with Dave McCoy, myself, and Greg Briner from IBM GlobalFinancing. IBM is able to offer creative "project financing" that can often times match theactual monthly savings, resulting in net zero cost to your operational budget, with payback periods as little as 2.5 years.

To get beyond the simple statistics of vendor popularity, we looked at the number and combinations of vendors with which enterprises work. Many were customers of one or two storage providers, but the rest were customers of up to six storage providers. More than one-third were customers of systems vendors only, bypassing storage specialists.
Comparisons between solutions vendors and storage component vendors are not new. One could argue that this can be compared to supermarkets and specialty shops.
Supermarkets offer everything you need to prepare a meal. You can buy your meat, bread, cheese,and extras all with one-stop shopping. In a sense, IBM, HP, Sun and Dell are offering this to clients who prefer this approach. Not surprisingly, the two leaders in overall storage hardware,IBM and HP, are also the two best to offer a complete set of software, services, servers and storage.
IBM and HP are also the leaders in tape.While Forrester reports that many large enterprises in North America prefer to buy diskfrom storage specialists, others have found that customers prefer to buy their tape from solution providers. Recently, Byte and Switch reports thatLTO Hits New Milestones,where the LTO consortium (IBM, HP, and Quantum) have collectively shipped over 2 million LTO tape drives, and over 80 million LTO tape cartridges. Perhaps this is because tape is part of an overallbackup, archive or space management solution, and customers trust a solution vendor overa storage specialist.
Where possible, IBM brings synergy between its servers and storage. For example, we justannounced the IBM BladeCenter Boot Disk System, a 2U high unit that supports up to 28 blade servers, ideal for applications running under Windows or Linux, and helping to reduce the energy consumption for thoseinterested in a "Green" data center.
Some people prefer buying their meat at the slaughterhouse, bread at the French pastry shop, andso on. Storage specialists focus on just storage, leaving the rest of the solution, like servers,to be purchased separately from someone else. Storage vendors like NetApp, EMC, HDS and othersoffer storage components to customers that like to do their own "system integration", or to thosethat are large enough to hire their own "systems integrator".
Storage specialists recognize that not everybody is a "specialty shop" shopper.HDS has done well selling their disk through solution vendorslike HP and Sun. EMC sells its gear through solution vendor Dell.
Interestingly, I have met clients who prefer to buy IBM System Storage N series from IBM, becauseIBM is a solution vendor, and others that prefer to buy comparable NetApp equipment directly fromNetApp, because they are a storage component vendor.
I mostly buy my groceries at a supermarket, buthave, on occasion, bought something from the local butcher, baker or candlestick maker. And if you are ever in Tucson, you might be able to find Mexican tamalessold by a complete stranger standing outside of a Walgreens pharmacy, the ultimate extreme of specialization. You can get a dozen tamales for tenbucks, and in my experience they are usually quite good. Theoretically, if you get sick, or they don't taste right, you have no recourse, and will probably never see that stranger again to complain to.(And no, before I get flamed, I am not implying any major vendor mentioned above is like this tamale vendor)
Of course, nothing is starkly black and white, and comparisons like this are just to help provide context and perspective,but if you are looking to have a complete IT solutionthat works, from software and servers to storage and financing, come to the vendor you can trust, IBM.
A few weeks ago, my Tivo(R) digital video recorder (DVR) died. All of my digital clocks in my house were flashing 12:00 so I suspect it wasa power strike while I was at the office. The only other item to die was the surge protector,and so it did what it was supposed to do, give up its own life to protect the rest of myequipment. Although somehow, it did not protect my Tivo.
I opened a problem ticket with Sony, and they sent me instructions on how to send itover to another state to get it repaired.Amusingly, the instructions included "Please make a backup of the drive contents beforesending the unit in for repair." Excuse me? How am I supposed to do that, exactly?
My model has only a single 80GB drive, and so my friend and I removed the drive and attachedit to one of our other systems to see if anything was salvageable. It failed every diagnostictest. There was just not enough to read to be usable elsewhere.
This is typical of many home systems. They are not designed for robust usage, high availability, nor any form of backup/recovery process. Some of the newer models havetwo drives in a RAID-1 mode configuration, but most have many single points of failure.
And certainly, it is not mission critical data. Life goes on without the last few episodesof Jack Bauer on "24", or the various Food Network shows that I recorded for items I planto bake some day. For the past few weeks, I have spent more time listening to the radioand reading books. Somehow, even though my television runs fine without my Tivo, watchingTV in "real time" just isn't the same.
I suspect that if you gave someone a method to do the backup, most would not bother to useit. People are now relying more and more heavily on their home-basedinformation storage systems, digital music, video and cherished photographs. Perhaps experiencing a "loss" will help them appreciate backup/recovery systems so much more than they do today.
The smart people at the University of Pittsburgh manage five campuses and over 33,000 students, andneeded to create an enterprise storage solution that would give it three key benefits. Of course, they turnedto IBM, the number one overall storage hardware vendor, to deliver.
A new storage infrastructure with the capacity to grow with the University of Pittsburgh as needed
Improved system reliability with reduced downtime, and availability 24/7/365
A significantly more manageable storage solution that could lower costs and provide better system efficiency through virtualization
As a result, IBM shipped its 25,000th high-end disk storage system, in this case two IBM System Storage DS8300 models, along with storage virtualization, and other related hardware, software and services, to provide a complete end-to-end solution.
Here is what Jinx Walton, Director of Computing Services and Systems Development at the University of Pittsburgh, had to say about it...
"The University of Pittsburgh supports large enterprise systems, and the number and complexity of new systems continue to grow. To effectively manage these systems it was necessary to identify an enterprise storage solution that would leverage our existing investments in storage, make allocation of storage flexible and responsive to project needs, provide centralized management, and offer the reliability and stability we require. The integrated IBM storage solution met these requirements"
ESG Analyst, Tony Asaro, talks about the many small storage startups having aBillion Dollar Impact on the storage system industry. Tony has counted over50 storage system vendors that are now in the marketplace. Is it really that many?Most of the time, the media only focus on the top seven major players, but I agree that big players like IBM should take trends about small startups like this seriously.
EMC Blogger Chuck Hollis suggests that this trend might be the start of a squeeze play, where top players and new upstarts squeeze out the middle playerslike Sun and HDS, in his postDesperate Times In Storage Land?
(His statement that IDC and Gartner have listed EMC as number one in "almost all"market segments is perhaps a bit misleading. IBM is number one in overall storage hardware, as wellas leading in tape drives, tape libraries, tape virtualization, and for that matter,disk virtualization. I don't know if IDC or Gartner count EMC Disk Library in the "tape virtualization" category, or if either analyst distinguishes between "cache-based" versus "switch-based" disk virtualization as separate categories.Perhaps Chuck should have qualified this to say "almost all of themarket segments that EMC does business in," which of course is better than the othervendors in the middle.)
Often, when looking at disk storage it is easy to focus on comparisons to other disk storage, but disruptive technologies cross boundaries. Already we have seen Flash Memory drives on the IBM BladeCenter, replacing traditional disk drives internal to each blade server. They are smaller than regular disk drives, but big enough to hold the operating system to boot from.
The New York Times has an article by John Markoff, Redefining the Architecture of Memory that talks about IBM's research on "Racetrack Memory".The article is a good read, but here are some interesting excerpts:
Now, if an idea that Stuart S. P. Parkin is kicking around in an I.B.M. lab here is on the money, electronic devices could hold 10 to 100 times the data in the same amount of space.
Currently the flash storage chip business is exploding. Used as storage in digital cameras, cellphones and PCs, the commercially available flash drives with multiple memory chips store up to 64 gigabytes of data.
However, flash memory has an Achilles’ heel. Although it can read data quickly, it is very slow at storing it. That has led the industry on a frantic hunt for alternative storage technologies that might unseat flash.
Mr. Parkin’s new approach, referred to as “racetrack memory,” could outpace both solid-state flash memory chips as well as computer hard disks, making it a technology that could transform not only the storage business but the entire computing industry.
But ultimately, the technology may have even more dramatic implications than just smaller music players or wristwatch TVs, said Mark Dean, vice president for systems at I.B.M. Research.“Something along these lines will be very disruptive,” he said. “It will not only change the way we look at storage, but it could change the way we look at processing information. We’re moving into a world that is more data-centric than computing-centric.”
This technology has the potential to break some of the physical limitations that are currently worrying disk drive designers. I look forward to see how this plays out.
Registration for the "Meet the Storage Experts" event in Second Life will close this week fornext week's September 20 event. All IBMers, clients and IBM Business Partners are welcome to attend. We will focus this time on DS3000 and N series disk systems, tape systems,and IBM storage networking gear.
If you miss this one, we plan to have another one in November!
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.
When new technologies are introduced to the marketplace, it is normal for customers to be skeptical.
My sister is a mechanical engineer, so when she needs to configure a part or component, she candesign it on the computer, and then use a "Rapid Prototyping Machine"that acts like a 3D printer, to generate a plastic part that matches the specifications. Some machinesdo this by taking a hunk of plastic and cutting it down to the appropriate shape, and others use glue andpowder to assemble the piece.
But not everything is that simple. Harry Beckwith deals with the issue of selling services and software featuresin his book "Selling the Invisible". How do you sell a service before it is performed? How do you sell a softwarefeature based on new technology that the customer is not familiar with?
Our good friends over at NetApp, our technology partners for the IBM System Storage N series, developed a"storage savings estimator" tool that can provide good insight into the benefits of Advanced Single InstanceStorage (A-SIS) deduplication feature.
I decided to run the tool to analyze my own IBM Thinkpad C: drive (Windows operating system and programs) and D: drive ("My Documents" folder containing all my data files) to see how much storage savings thetool would estimate. Here are my results:
WINXP-C-07G (C: drive)Total Number of Directories: 1272Total Number of Files: 56265Total Number of Symbolic Links: 0Total Number of Hard Links: 41996Total Number of 4k Blocks: 2395884Total Number of 512b Blocks: 18944730Total Number of Blocks: 2395884Total Number of Hole Blocks: 290258Total Number of Unique Blocks: 1611792Percentage of Space Savings: 20.61Scan Start Time: Wed Sep 5 14:37:06 2007Scan End Time: Wed Sep 5 14:53:51 2007
WINXP-D-07H (D: drive)Total Number of Directories: 507Total Number of Files: 7242Total Number of Symbolic Links: 0Total Number of Hard Links: 11744Total Number of 4k Blocks: 3954712Total Number of 512b Blocks: 31610595Total Number of Blocks: 3954712Total Number of Hole Blocks: 3204Total Number of Unique Blocks: 3524605Percentage of Space Savings: 10.79Scan Start Time: Wed Sep 5 14:21:16 2007Scan End Time: Wed Sep 5 14:34:30 2007
I am impressed with the results, and have a better understanding of the way A-SIS works. A-SIS looks at every4kB block of data, and creates a "fingerprint", a type of hash code of the contents. If two blocks have different "fingerprints", then the contents are known to be different. If two blocks have the same fingerprint, it is mathematically possible for them to be unique in content, so A-SIS schedules a byte-for-byte comparison to be sure they are indeed the same. This might happen hours after the block is initially written to disk, but is a much safer implementation, and does not slow down the applications writing data.
(In an effort to provide support "real time" as data was being written, earlier versions of deduplication
had to either assume that a hash collision was a match, or take time to perform the byte-for-byte comparisonrequired during the write process. Doing this byte-for-byte comparison when the device is the busiest doingwrite activities causes excessive undesirable load on the CPU.)
The estimator tool runs on any x86-based Laptop, personal computer or server, and can scan direct-attached, SAN-attached, or NAS-attached file systems. If you are a customer shopping around for deduplication, ask your IBM pre-sales technical support, storage sales rep, or IBM Business Partner to analyze your data. Tools like this can help make a simple cost-benefit analysis: the cost of licensing the A-SIS software feature versus the amount of storage savings.
I can't believe I have been blogging for a year now!
I have Jennifer Jones from IBM to thank for getting this started. She was my predecessor in the job I have now, and she was moving on to bigger and better things, and during the transition for me to take over, she suggested that we start a blog, podcast, or similar. While there are many blogs and podcasts inside the firewall of IBM, I wanted something to be accessible to all of our IBM sales team, IBM Business Partners, existing and prospective clients, and to enable comments, to enable two-waycommunication. Podcasts are very one-way, so we chose a blog instead.Getting it set up took a while, convincing our own management that this was worthwhile, and dealing with our legal department on the IBM blogging guidelines of what we can and cannot write about, we finally got it going last year, launching September 1, just in time for our 50 years of disk systems innovation campaign.
It has been a wild ride, a great learning experience, and has proven quite fulfilling for job satisfaction. Here are some observations and lessons I have learned along the way.
Roller is the open source blog server that drives Sun Microsystem's blogs.sun.com employee blogging site, IBM DeveloperWorks blogs that this blog exists on, thousands of internal blogs at IBM Blog Central, the JRoller Java community site, and hundreds of others world-wide.Whereas there might be fancier blog systems elsewhere that I could have chosen, hosting my blog with IBM Developerworksseemed like a good choice. I can access from any web-browser capable machine, and enter my blog posts in nativeHTML, that I develop in the tool itself, or offline with a standard basic text editor like Microsoft Notepad that I can then cut-and-paste back in.
One lesson I learned the hard way was that Roller generates the Permalink URL for each blog post based on the first five words of the title. For that reason, it is important to chose an appropriate and unique title, avoiding the use of punctuation, quotation marks, or pharmaceutical "enhancement products" that might get rejected by SPAM filters.Once chosen, you can't change the title afterwards as it won't match the Permalink anymore.My blog post "Aperi is (enhancement product) for SMI-S" caused no end of grief to our Press Release team.
Writing blog posts in native HTML is not as hard as it sounds. I am limited to hosting a maximum of 24MB of files, and they can only be jpg, jpeg, gif, png, mp3, pdf or ppt format.So, wherever possible, I point to other websites for content.For those new to blogging, I recommendThe Barebones Guide to HTML.
Roller also generates for me a spreadsheet of all my page views for the week. Tracking blog traffic closely is as crazyas checking your company's stock price every day. These "web-stat" e-mails get filed directly into my Bacn folder on Lotus Notes.
In my earlyadvice to bloggers, I mentioned my choice of Bloglines as my RSS feed reader. When I subscribe to a new blog, I specify Full entries, not Partial,which allows me to scan it quickly, but filters out many of the non-text content like videos. It also allowed meto see what my own blog posts looked like from within a reader, so that I can write them appropriately.
I find if valuable to read other blogs, including those written by employees of our toughest competitors. Evenif you don't blog yourself, following blogs can be extremely valuable. Be careful what you leave as comments onother blogs, they may come back to haunt you later.
Currently, I track 55 blogs, some about storage,marketing, Web 2.0 issues, Second Life, Linux, or other areas of interest. I prefer blogs that make only 1-5 postsper week, so blogs like LifeHacker and LifeRemix are off my Bloglines list, but are excellent resourceswhen I am searching for something specific. If you think 55 is a lot of blogs, consider Timothy Ferriss' post onHow RobertScoble reads 622 RSS feeds each morning.
I have quite an international readership, so I have to be careful using American idioms and pop cultural references.For example, in my blog post IBM acquires Softek, I mentioned "shotgun weddings" and had various responses asking what exactly did that mean,all from readers outside the USA. I've learned that sometimes you need to link them to an American Slang dictionary,or Wikipedia encyclopedia entry to explain these terms and phrases.
Technoraticurrently tracks over 100 million blogs and over 250 million pieces of tagged social media. Getting my blogtracked had some issues. You have to join, thenpost a "claim"on your own blog. My mistake was having a case-sensitive URL with a mix of upper and lower case letters, but Technorati prefers all lower case. IBM worked with Technorati to get this resolved.
Del.icio.us is a social bookmarking website -- the primary use is to store your bookmarks online, which allows you to access the same bookmarks from any computer and add bookmarks from anywhere, too. On del.icio.us, you can use tags to organize and remember your bookmarks, which is a much more flexible system than folders.
I use Firefox, Safari, Dillo and Internet Explorer web browsers, so it is nice that I have access to allmy bookmarks in the same consistent manner. When I see content on a website that I might like to reference laterin a blog, I tag it with del.icio.us so that I can get to it later.
Fellow GTD-ers will quickly recognize this acronym, but for the rest of you, it refers to David Allen's book "Getting Things Done®".This is a great book! I learned about it reading other people's blogs, and found it incrediblyuseful helping me organize my time.There are various online tools available to help employ this method. I use Lotus Connections Activitiesfor group projects with co-workers at IBM, and BackPack for projects withmy friends outside of work.
The success of YouTube encouraged IBM to launch IBM TV, a portal for IBM's video and multimedia assets and make it easier for IBM employees, customers, partners and prospects to access and view IBM multimedia. The plan is to have eight anchor episodes per year, professionally hosted by TV personality, Joe Washington, and point to related offers and other resources for viewers to learn more.
Blogging also introduced me to Second Life. I asked around if anyone else within IBM was using Second Life, anddiscovered quite a few. I got invited to join our internal Eightbar group, and participated in various events, including an IBM Holidayparty that I discussed in my blog post"Building a Snowman in Second Life".
In April, we had a launch of our newest products in Second Life, and we plan to have two more Second Life events,September 20 and another in November, staged as "Meet the Experts" question and answer panels.
I wrap up with Facebook. Actually, whereas most of my Web 2.0 efforts have been work-related, I have quite a few friends and family who follow my blog. Several were inspired to start their own blogs, such asPassages from Pamand Barry Whyte on Storage Virtualization. Bridging the gap is Facebook, something I can use to keep tabs on my friends, as well as my storage industry-related contacts.
Wow, that's quite a lot in one year. Well, I am done with my meetings down here in Sao Paulo, Brazil. My colleauges and I are returning tonight to enjoy the long Labor Day weekend.
August 31 is my good friend Jim Cosentino's retirement day as a full-time employee at IBM. After over 30 years at IBM, in various marketing, sales and consulting roles, he is going to be thinking about happy things instead of working. His last seven years has been at theIBM Poughkeepsie Customer Executive Briefing Center as the lead System Storage presenter.
The past few years, I've traveled with him around the world on various business trips, teaching our IBM sales force and IBM Business Partners about our System Storage offerings, and presenting to clients. He is a class act, always positive, laughing, seeing the bright side of things.
While "spend more time with his family" has become a business cliche, I know Jim will actually enjoy his retirement years, spend more time with his family, take on other pursuits and hobbies, and perhaps do some more traveling.
Jim, if you are reading this, I have one suggestion. I know you have lots of friends within IBM, and count myself as one of them, but may I suggest your first goal is to makeat least three newfriends, to help you in your transition to retirement.
Congratulations Jim! Enjoy your well-deserved retirement!
If you are ever down in Sao Paulo, Brazil, may I suggest not drinking "American amounts" of their "Brazilian Coffee". The coffee here is "robust", to say the least.
Yesterday, my blog focused on IBM iSCSI offerings that were announced in August.Also announced earlier this month, the Integrated Removable Media Manager (IRMM) on System zhas been years in the making.IRMM is a new robust systems management product for Linux® on IBM System z™ that manages open system media in heterogeneous distributed environments and virtualizes physical tape libraries. IRMM combines the capacity of multiple heterogeneous libraries into a single reservoir of tape storage that can be managed from a central point.By providing an integrated solution with the opportunity for both mainframe z/OS DFSMSrmm and distributed Tivoli® Storage Manager™ environments to be managed by IRMM, System z can now be a hub for the management of removable media.
The people who thought the "Mainframe is obsolete", and those that thought "Tape is dead", are both proven wrong again with this announcement. People are looking to deploy robust tape automation for backup and archive, and this convergence with mainframe makes perfect sense by providing business value that extends to other distributed systems.
The proof-of-concept that IBM Haifa research center developed back in 1998 became what we now call the iSCSI protocol.The book iSCSI: The Universal Storage Connection introduces the history as follows:
In the fall of 1999 IBM and Cisco met to discuss the possibility of combining their SCSI-over-TCP/IP efforts. After Cisco saw IBM's demonstration of SCSI over TCP/IP, the two companies agreed to develop a proposal that would be taken to the IETF for standardization.
There are three ways to introduce iSCSI into your data center:
Through a gateway, like the IBM System Storage N series gateway, that allows iSCSI-based servers connect to FC-based storage devices
Through a SAN switch or director, a FC-based server can access iSCSI-based storage, an iSCSI-based server accessing FC-based storage, or even iSCSI-based servers attaching to iSCSI-based storage.
Directly through the storage controller.
IBM has been delivering the first method with its successful IBM System Storage N series gateway products, buttoday we have announced additional support for the second and third methods.Here's a quick recap.
New SAN director blades
Supporting the second method, IBM TotalStorage SAN256B Director is enhanced to deliver iSCSI functionality with a new M48 iSCSI Blade, which includes 16 ports (8 Fibre Channel ports; and 8 Ethernet ports for iSCSI connectivity). We also announced a new Fibre Channel M48 Blade which provides 10 Gbps Fibre Channel Inter Switch Link (ISL) connectivity between SAN256B Directors.
With support for Boot-over-iSCSI, diskless rack-optimized and blade servers can boot Windows or Linux over Ethernet,eliminating the management hassles with internal disk.
All of this is part of IBM's overall push into the Small and Medium size Business marketplace, making it easier to shop for and buy from IBM and its many IBM Business Partners, easier to deploy and install storage, and easier tomanage the storage once you have it.
In his blog Rough Type, Nick Carr asks Where is my CloudBook?and points to John Markoff's 2-part series in the New York Times on computing in the clouds.(Read it here: Part 1, Part 2)
At first, I thought he meant computing while in an airplane, but instead, he is talking about computing on a laptop or other hand-held device that does not have an internal disk drive, no installedoperating system, no internal data storage. Instead, the idea is that you boot from a CD, accessyour data, and even some of your programs, over the internet. John used an Ubuntu Linux LiveCD in his example.
This week, I am in Sao Paulo, Brazil, and was "in the clouds" for over 10 hours flying from Dallas to here.The one time I am guaranteed "off-line" from the internet is on the plane, and I spend enough time on planesthat I am able to get work done despite being "disconnected".
The same reasons people want to get out of having a disk drive on their laptop, are the reasons data centersare getting out of internal disk on their servers.
disks crash, and typically are not protected in any RAID configuration on most laptops
operating systems get infected with viruses and malware
storage on one server is generally inaccessible to every other server
Booting from CD is especially clever. No more worrying about fixing your Windows registry, viruses,corrupted operating system files, or the cruft that accumulates on your C: drive that slowsyou down. The CD is the sameevery time, so it is like running your system with a freshly installed operating system every day.
The need for central repositories of data harkens back to the years of the IBM mainframe. Of course, whatmade sense back then continues to make sense now. The old 3270 terminals stored no data, and instead merelyprovided keyboard input and display text screen output to the vast amount of data stored on the central system.Today, the inputs are different, using your finger or mouse instead to point to what you want, sliding itacross to make things happen, and the output may now include photos, audio and video, but the concept isstill the same.
I carry my Ubuntu Linux LiveCD with me on every business trip. Combined with externally rewriteable media,such as a USB key, you can get work done even when you are in an airplane, and upload it whenyou are back on the net.
The IBM Storage and Storage Networking Symposium concludes today. As typical for manysuch conferences, it ended at noon, so that people can catch airline flights.
TS1120 Tape Encryption - Customer Experiences
Jonathan Barney had implemented many deployments of tape encryption, and shared hisexperiences at two customer locations.
The first company had decided to implement their EKM servers on dedicated 64-bitWindows servers. They had three sites, one in Chicago, Alphareta, and New York City,each with two EKM servers. Each library had a single TS3500 tape library, and pointedto four EKM servers, two local, and two remote.
The clever trick was managing the keystore. They decided that EKM-1 was their trustedsource, made all changes to that, and then copied it to the other five EKM servers.His team deployed one site at a time, which turned out to be ok, but he would notrecommend it. Better to design your complete solution, and make sure that all librariescan access all EKM servers.
This company decided to have a single key-label/key-pair for all three locations, but change it every 6 months. You have to keep the old keys for as long as you have tapesencrypted with those keys, perhaps 10-20 years.The customer found the IBM encryption implementation "elegant" and it can be easily replicated to a fourth site if needed.
The second company had both z/OS and Sun Solaris. Initially they planned to have botha hardware-based keystore on System z, and software-based keystore on Sun, but they realized that System z version was so much more secure and reliable, that it made nosense to have anything on the Sun Solaris platform.
On System z, they had two EKM images, and used VIPA to ensure load balancing fromthe library. Tapes written from z/OS used DFSMS Data Class to determine which tapesare encrypted and which aren't. All Tapes written from Sun Solaris were encryptied, written to a separate logical library partition of the TS3500, which in turn contactedthe System z for the EKM management to provide the keys to use for the encryption.
The "gotcha" for this case was that when they tested Disaster Recovery, they had torecover the two EKM servers first, before any other restores could take place, and thistook way too long. Instead, they developed a scaled-down 10-volume "rescue recovery" z/OS image that would contain the RACF database and all EKM related software to actas the keystore during a disaster recovery. Anytime they make updates, they only haveto dump 10 volumes to tape. Restore time is down to only 2 hours.
He gave this advice to deploy tape encryption:
Some third party z/OS security products, like Computer Associates Top Secret orACF2, require some PTFs to work with the EKM. The latest IBM RACF is good to go.
Getting IP support from IOS to OMVS requires IPL.
At one customer, an OMVS monitor software program killed the EKM because it wasn'tin their list of "acceptable Java programs". They updated the list and EKM ran fine.
DO not update EKM properties file while EKM is running. EKM keeps a lot of stuffin memory, and when it is recycled, copies this back to the EKM properties file, reversing any changes you may have done. It is best to shut down EKM, update theproperties file, then start up EKM back up again. This is why you should always haveat least two EKM servers for redundancy.
TSM for Linux on System z
Randy Larson from our Tivoli group presented this session.There is a lot of interest in deploying IBM Tivoli Storage Manager backup and archivesoftware on Linux for System z. Many customers are already invested in a mainframeinfrastructure, may have TSM for z/OS or z/VM, and want the newer features and functions that are available for TSM on Linux.
TSM has special support for Lotus Domino, Oracle, DB2 and WebSphere Application Servers.TSM clients can send backup data to a TSM server internally via Hipersockets, a virtualLAN feature on the System z platform that uses shared memory to emulate TCP/IP stack.
One of the big questions is whether to run Linux as guests under z/VM, or natively onLPAR. The general deployment is to carve an LPAR and run Linux natively untilyour server and storage administration staff have taken z/VM training classes. Oncetrained, they can easily move native LPAR images to z/VM guests. Unlike VMware that takesa hefty 40% overhead on x86 platforms to manage guests, z/VM only takes 5-10% overhead.
For the TSM database and disk storage pools, Randy recommends FC/SCSI disk, with ext3 file system, combined with LVM2 into logical volumes. ECKD disk and reiserfsworks too. Avoid use of z/VM minidisks. Under LVM2, consider 32KB stripes for the TSM database, and 256KB stripes for the disk storage pools. For multipathing, usefailover rather than multibus method. Read IC45459 before you activate "directio".
The TSM for Linux on z is very much like the TSM on AIX or Windows, and not like theTSM for z/OS. For tape, TSM for Linux on z does not support ESCON/FICON attached tape,you need to use FC/SCSI attached tape and tape libraries. TSM owns the library anddrives it uses, so give it a logical library partition separate from z/OS. ForSun/StorageTek customers, TSM works with or without the Gersham Enterprise Distrbu-Tape(EDT) software. Use the IBM-provided drivers for IBM tape. For non-IBM tape, TSM providessome drivers that you can use instead.
That wraps up my week. This was a great conference! If you missed it, look for the one in Montpelier, France this October. Check out the list of IBM Technical Conferencesto find others that might interest you.
The IBM Storage and Storage Networking Symposium continues ...
DS8300 Benchmark for Global Mirror
Phil Allison of Fidelity National Information Services presented his success switching from competition over to IBM DS8300 disk systems for use with Global Mirror. They had usedPerformance Associates famous PAIO driver to help to the benchmarktesting. They ran the benchmars at 2x and 3x their current workloads to see how well the DS8000 performed,measuring IOPS, MB/sec, and millisecond response time (msec). They were very impressed with their results,staying below their target 0.8 msec for most of their runs.
For the Global Mirror, the did a performance "bake-off" between Ciena CN2000 versus Cisco 9216i. These areimplemented differently. Ciena uses a Layer-2 approach, encapsulating the Fibre Channel packets directlyto transport as SDH/SONET or Gigabit Ethernet (GigE), which required dedicated circuits between JacksonvilleFlorida and Little Rock, Arkansas. By contrast, Cisco uses a Layer-3 approach, encapsulating Fibre Channelpackets within an IP packet, which can leverage existing datacenter-to-datacenter backbone.
To add stress to the benchmarks, they used a "Network Impairment" emulator. These artificially inject errors,lose packets, and other signal loss conditions. Running both Cisco and Ciena under these tests help them decide which to purchase, but also enforced that idea that they made the right choice choosing IBM for theirremote distance mirroring solution.
Comparison of Bare Machine Recovery Techniques
"Bare machine recovery" is the phrase used to restore a machine that has no operating system installed (or thewrong operating system). Dave Canan from IBM Advanced Technical Support did a great job reviewing the variousproducts and techniques available, and the pros and cons of each approach. The ones he covered were:
Tivoli Storage Manager - install fresh Windows Operating System, TSM client, and then follow certain steps
Automated System Recovery(ASR) - a new feature of Windows XP and Windows 2003 works with TSM client
Symantec Ghost - formerly callled PowerQuest Drive Image, there are now two versions: Ghost Home Edition and Ghost Corporate Solution Suite
Cristie Bare Machine Recovery(CBMR) - This is an IBM partner that provides both Linux and Windows PE versions. Cristie includes a license for Windows PE, so no need to use the alternative Bart PE method.
SAN Volume Controller - Customer Experience
Bill Giles of Catholic Medical Center, a hospital in New Hampshire, presented his experienceswith IBM System Storage SAN Volume Controller. They have a mix of IBM System x, System p, andSystem i servers, as well as machines from HP, Sun, and Dell. For applications, they havePicture Archiving and Communicatiion System (PACS) for cardiology and radiology, HL7 Interface engine, Clinical Information System, TSM for backup, and Microsoft Exchange fore-mail.
They deployed SVC on AIX, Solaris, Windows 2000 and 2003. They were very delightedwith the results:
Centralized Storage Provisioning
Consolidating disparate storage into a universal platform
Enables non-disruptive data migration
Increased utilization of existing disk resources
Improved disaster recovery with FlashCopy and Metro Mirror
Birds of a Feather (BOF) sessions
We had two BOFs, one for storage attached to System z operating systems, and another for storage attached to Linux, UNIX and Windows systems. This distinctionmade sense when mainframes could only attach to CKD disks and ESCON/FICON tape,and distributed systems could only do FCP/SCSI, but these days, there are all kindsof convergence going on.
Linux on System z can now attach via FCP to LTO tape and SAN Volume Controller, allowing now a wide range of storage options for that platform. z/OS, z/VM, z/VSEand Linux on System z can all access IBM System Storage N series via NFS.
The format was traditional Q&A panel, we had experts at the front of the room,handling the questions and discussion topics brought up by the audience. I'll spareyou the individual questions and answers.
The IBM Storage and Storage Networking Symposium in Las Vegas continues ...
N series and VMware
Jeff Barnett presented how VMware manages disk image files in its VMfs repository, and how N series offersa better alternative. Virtual machines can access N series volumes directly.
Business Continuity with System i
Allison Pate presented the various Business Continuity options for System i. Many customersuse internal storage for System i, but this then hampers Business Continuity efforts. Instead,you can have IBM System Storage DS8000 or DS6000 series disk systems provide disk mirroringbetween clustered systems.
There was a lot of interest in DR550, one of our many compliance storage solutions. Ron Henkhauspresented an overview of our DR550 and DR550 Express offerings. Unlike the competitive disk-onlysolutions, such as the EMC Centera, the DR550 allows you to attach an automated tape library, managing large amounts of fixed content data at a much lower cost point. It also has encryption, for both diskand tape data.
Open Systems Disk Management
Siebo Friesenborg presented the various steps needed to troubleshoot performance problemswith open systems, including the use of "iostat" on AIX systems as an example, and the stepsyou can take to make formal Service Level Agreements (SLA) between the IT department and thevarious lines of business.
IBM Encryption - TS1120 and LTO-4 encryption comparison
Tony Abete presented TS1120 and LTO-4 encryption techniques. Deploying encryption is more thanjust choosing a tape drive. There are a variety of factors involved, such as whether to managethe keys from the application, the operating system, or the library manager. You need policiesto decided when to encrypt tapes and when not to, generating your keys, storing them, and sharingthem with your business partners, suppliers and service providers with which you send tapes.
I can tell that many people are feeling like they are "drinking from a firehose".IBM's success in storage reaches out to so many different aspects of information management,a variety of industries, and disciplines as varied as regulatory compliance and medical imaging.
Registration is now open for our next "Meet the Storage Experts" event in Second Life. All IBMers, clients and IBM Business Partners are welcome to attend. We will focus this time on DS3000 and N series disk systems, tape systems,and IBM storage networking gear.

Continuing this week in Las Vegas, we had a great set of sessions today.
Fibre Channel Overview
I like the manner in whichJim Robinson presented this "basics" session on how Fibre Channel works, why it is spelled "Fibre" not "Fiber", and how all the different layers work in the protocol.
IBM Virtualization Engine TS7700 series
Jim Fisher from the IBM Tucson lab presented the TS7700 series, which replaces our Virtual Tape Server (VTS). Hehad performance numbers to show that it was faster in various measurements against the B20 model of the VTS. Itis supported on the z/OS, z/VM, z/VSE, TPF and z/TPF operating systems.
IBM E-mail Archiving and Storage solution
Ron Henkhaus provided an overview of IBM's E-mail Archive and Storage appliance. The solution combines IBM BladeCenter server blade, DS4200 serieswith SATA disk, and pre-installed software: IBM Content Manager, IBM Records Manager, IBM CommonStore for Lotus Domino and Microsoft Exchange, and IBM System Storage Archive Manager. Services are included to get it connected toyour e-mail environment.
Lee La Frese from our Tucson performance lab presented various performance featuresof the IBM System Storage DS8000 series, and how they compare to competition.
First, some interesting statistics.
Back in 2002, the average high-end EnterpriseStorage Server (ESS) model F20 was configured only for 4 Terabytes (TB). In 2004,the average ESS was up to 12 TB. Today, the average DS8100 is 17.4 TB and the averageDS8300 is 41.5 TB.
51 percent of DS8000 series are configured for FCP only (Linux, UNIX, Windows, i5/OS),35 percent FICON only (System z mainframe), and 14% have both mixed.
Average I/O density has stabilized to about 0.6 IOPS per GB. This means that for everyTB of business data, you can expect most applications to issue 600 Input/Output requestsper second.
While IBM SAN Volume Controller has the fastest SPC-1 and SPC-2 benchmarks, the DS8000also has good results. Looking at just the monolithic "scale-up" systems, DS8000 hasthe fastest SPC-1, and second place for SPC-2.
Compared against the EMC DMX-3, the IBM DS8000 series has superior performance.For example, comparing 2Gbps port performance on each, DMX-3 is able to do 20 IOPS perport, compared to DS8000 with 38 IOPS per port.Compared against HDS USP, the response time for 60,000 IOPS for HDS averaged 10.5 milliseconds (msec), compared to IBM DS8000 less than 6.5 msec.
There are some unique features of the DS8000 to optimize performance. Two areAdaptive Multi-stream Prefetching (AMP) which helps improve processing of databasequeries, and HyperPAV which helps on mainframe workloads.
For FATA disks, performance of sequential reads and writes is only 20 percent less than15K RPM FC disks, but a whopping 50 percent less for random access. Consider using FATAfor audio/video streaming, surveillance data, seismic recordings, and medical imaging.
Comparing 146GB 10K versus 300GB 15K from a capacity perspective was interesting.37TB of 300GB 15K had 20 percent better response time, but 25 percent less maximum throughput,than 37TB of 146GB drives. Depending on your workload, this can help decided which youchoose.
Lee also covered RAID rebuild performance. When an individual HDD fails that is part of a RAIDgroup, the DS8000 performs a rebuild onto a spare drive. A RAID-5 rebuild is processedat 52 MB/sec, compared to RAID-10 at 56 MB/sec. Rebuild processing is low priority,so any other workload will take higher priority to avoid impacting application performance.Compared to EMC, the IBM DS8000 can rebuild RAID-5 73GB 15K RPM drive in only 24 minutes, but it takes 37 minutes to do this on a DMX-3. That is 13 minutes of additional exposure where a second drive failure might cause you to lose all your data in that RAID group!
N series ILM and Business Continuity
James Goodwin from our Advanced Technical Support team presented IBM System Storage N series featuresthat relate to ILM and Business Continuity. He covered features like SnapShot, SnapLock,SnapVault and LockVault.
I have arrived safely in Las Vegas for the IBM System Storage and Storage Networking Symposium. This eventis held once every year. The gold sponsors were: Brocade, Cisco, Finisar, Servergraph, and VMware. Our silversponsor was Qlogic.
I presented IBM's System Storage strategy and an overview of our product line. For those who missed it,our strategy is focused on helping customers in four key areas:
Optimize IT - to simplify and automate your IT operations and optimize performance and functionality, through server/storage synergies, storage virtualization, and intergrated storage infrastructure management.
Leverage Information - to enable a single view of trusted business information through data sharing, and to get the most value from information through Information Lifecycle Management (ILM).
Mitigate Risk - to comply with security and regulatory requirements, and keep your business running with a complete set of business continuity solutions. IBM offers a range of non-erasable, non-rewriteable storage, encryption on disk and tape, and support for IT Infrastructure Library (ITIL) service management disciplines.
Enable Business Flexibility - to provide scalable solutions and protect your IT investment through the use of open industry standards like Storage Networking Industry Association (SNIA) Storage Management Initiative Specification (SMI-S). IBM offers scalability in three dimensions: Scale-up, Scale-out, and Scale-within.
IBM has a broad storage portfolio, in seven offering categories:
Disk Systems, including our SAN Volume Controller, DS family, and N series.
Tape Systems, including tape drives, libraries and virtualization.
Storage Networking, a complete set of switches, directors and routes
Infrastructure Management, featuring the IBM TotalStorage Productivity Center software
Business Continuity, advanced copy services and the software to manage them
Lifecycle and Retention, our non-erasable, non-rewriteable storage including DR550, N series with SnapLock, and WORM tape support, Grid Archive Manager and our Grid Medical Archive Solution (GMAS)
Storage Services, everything from consulting, design and deployment to outsourcing and hosting.
I could talk all day on this, but given that the room was packed, every seat taken and the rest of the audience standing along the walls, I had to keep it down to one hour.
SAN Volume Controller Overview
I presented an overview of the IBM System Storage SAN Volume Controller (SVC), IBM's flagship disk virtualizationproduct. Rather than giving a long laundry list of features and benefits,I focused on the five that matter most:
Reduces the cost and complexity of managing storage, especially for mixed storage environments
Simplifies Business Continuity through non-disruptive data migration and advanced copy services
Improves storage utilization, getting more value from the storage hardware you already have
Enhances personnel productivity, empowering storage administrators to get their job done
Delivers high availability and performance
SAN Volume Controller - Customer Success Stories
A good part of this conference are presented by non-IBMers, which include Business Partners and clientssharing their experiences. In this session, we had two speakers share their experiences with SVC.
David Snyder keeps over 80 web sites online and available. His digital media technologiesteam uses SVC to make their storage administration easier, and ensure high availability for web site content creation and publishing.
Mark Prybylski manages storage at his company, a financial bank. His storage management team uses SVC Global Mirror which provides asynchronous disk mirroring between different types of disk, as part oftheir Business Continuity/Disaster Recovery plan.
The last session I attended was "Storage .. to Optimize your ECM depoloyments" by Jerry Bower, now working for IBM as part of our recent acquisition of the Filenet company. ECM stands for Enterprise Content Management, and IBM is the market leader in this space. Jerry gave a great overview of IBM Content Manager software suite, our newly acquired Filenet portfolio, and the storage supported.
After the sessions was a reception at the Solution Center with dozens of exhibitor booths. For example,Optica Technologies had their PRIZM productswhich are able to connect FICON servers to ESCON storage devices.
I am back at "the Office" for a single day today. This happens often enough I need a name for it.Air Force pilots that practice landing and take-offs call them "Touch and Go", but I think I needsomething better. If you can think of a better phrase, let me know.
This week, I was in Hartford, CT, Somers, NY and our Corporate Headquarters in Armonk, in a varietyof meetings, some with editors of magazines, others with IBMers I have only spoken to over the phone andfinally got a chance to meet face to face.
I got back to Tucson last night, had meetings this morning in Second Life, then presented "InformationLifecycle Management" in Spanish to a group of customers from Mexico, Chile, and Brazil. We have a great Tucson Executive Briefing Center, and plenty of foreign-language speakers to draw from our localemployees here at the lab site.
Sunday, I leave for Las Vegas for our upcoming IBM Storage and Storage Networking Symposium. We will cover the latest in our disk, tape, storage networking and related software.Do you have your tickets? If you plan to attend, and want to meet up with me, let me know.
Last week, a writer for a magazine contacted us at IBM to confirm a quote that writing a Terabyte (TB) on disk saves 50,000 trees. I explained that this was cited from UC Berkeley's famousHow Much Information? 2003 study.
To be fair, the USA Today article explains that AT&T also offers "summary billing" as well as "on-line billing", but apparently neither of these are the default choice. I can understand that phone companies send out bills on paper because not everyone who has a phone has internet access, but in the case of its iPhone customers, internet access is in the palm of your hands! Since all iPhone customers have internet access, and AT&T knows which customers are using an iPhone, it would make sense for either on-line billing or summary billing to be the default choice, and let only those that hate trees explicitly request the full billing option.
Sending a box of 300 pages of printed paper is expensive, both for the sender and the recipient. This informationcould have been shipped less expensively on computer media, a single floppy diskette or CDrom for example. Forthose who prefer getting this level of detail, a searchable digitized version might be more useful to the consumer.
Which brings me to the concept of Information Lifecycle Management (ILM). You can read my recent posts on ILM byclicking the Lifecycle tab on the right panel, or my now infamous post from last year about ILM for my iPod.
His recollection of the history and evolution of ILM fairly matches mine:
The phrase "Information Lifecycle Management" was originally coined by StorageTek in early 1990s as a way to sell its tape systems into mainframe environments. Automated tape libraries eliminated most if not all of the concerns that disk-only vendors tout as the problem with manual tape. I began my IBM career in a product now called DFSMShsm which specifically moved data from disk to tape when it no longer needed the service level of disk. IBM had been delivering ILM offerings since the 1970s, so while StorageTek can't claim inventing the concept, we give them credit for giving it a catchy phrase.
EMC then started using the phrase four years ago in its marketing to sell its disk systems, including slower less-expensive SATA disk. The ILM concept helped EMC provide context for the many acquisitions of smaller companies that filled gaps in the EMC portfolio. Question: Why did EMC acquire company X? Answer: To be more like IBM and broaden its ILM solution portfolio.
Information Lifecycle Management is comprised of the policies, processes,practices, and tools used to align the business value of information with the mostappropriate and cost effective IT infrastructure from the time information isconceived through its final disposition. Information is aligned with businessrequirements through management policies and service levels associated withapplications, metadata, and data.
Whitepapers and other materials you might read from IBM, EMC, Sun/StorageTek, HP and others will all pretty much tell you what ILM is, consistent with this SNIA definition, why it is good for most companies, and how it is not just about buying disk and tape hardware. Software, services, and some discipline are needed to complete the implementation.
While the SNIA definition provides a vendor-independent platform to start the conversation, it can be intimidatingto some, and is difficult to memorize word for word.When I am briefing clients, especially high-level executives, they often ask for ILM to be explained in simpler terms. My simplified version is:
Information starts its life captured or entered as an "asset" ...
This asset can sometimes provide competitive advantage, or is just something needed for daily operations. Digital assets vary in business value in much the same way that other physical assets for a company might. Some assets might be declared a "necessary evil" like laptops, but are tracked to the n'th degree to ensure they are not lost, stolen or taken out of the building. Other assetsare declared "strategically important" but are readily discarded, or at least allowed to walk out the door each evening.
... then transitions into becoming just an "expense" ...
After 30-60 days, many of the pieces of information are kept around for a variety of reasons. However, if it isn'tneeded for daily operations, you might save some money moving it to less expensive storage media, throughless expensive SAN or LAN network gear, via less expensive host application servers. If you don't need instantaccess, then perhaps the 30 seconds or so to fetch it from much-less-expensive tape in an automated tape librarycould be a reasonable business trade-off.
... and ends up as a "liability".
Keeping data around too long can be a problem. In some cases, incriminating, and in other cases, just having toomuch data clogs up your datacenter arteries. If not handled properly within privacy guidelines, data potentially exposes sensitive personal or financial information of your employees and clients. Most regulations require certain data to be kept, in a manner protected against unexpected loss, unethical tampering, and unauthorized access, for a specific amount of time, after which it can be destroyed, deleted or shredded.
So ILM is not just a good idea to save a company money, it can keep them out of the court room, as well as help save the environment and not kill so many trees. Now that 100 percent of iPhone customers have internet access, and a goodnumber of non-iPhone customers have internet access at home, work, school or public library, it makes sense for companies to ask people to "opt-in" to getting their statements on paper, rather than forcing them to "opt-out".
Despite this, or perhaps because of this, over 30 percent of IBM's Linux server revenue is onnon-x86 platforms, avoiding the XenSource vs. VMware decision altogether. Both System z (traditional mainframe servers) and System p (traditional UNIX servers) are able to run many Linux images in a fully virtualized manner, without VMware or XenSource.
Philip Rosedale, chief executive of Linden Labs, which produced the Second Life virtual reality environment, said Second Life and Facebook are popular because they give people a new environment to interact in that they are comfortable with.
Of course I have blogged for months now on my involvement in Second Life, and how IBM is investing in this platform for business purposes. Recently, IBM made news for publishing its Code of Conduct,and set of guidelines on how you run your avatar in virtual worlds, including Second Life. IBM recognizesthe business potential of virtual worlds, and has formed the "3D Internet" group exploring the possibilities.Over 5000 IBM employees now use Second Life on a regular basis.
I was surprised to learn that there were over 23,000 IBMers already on Facebook. I used to be on LinkedIn,but found FaceBook to have more IBMers and have made the switch. Recently, we were told that these 23,000 IBMers spend 19 minutes, on average, per day visiting Facebook pages. Nobody askedme how much time I spend every day on FaceBook, but with over 350,000 employees in the company,I am sure some have ways to track the lives of others.
Both of these count as adding more "FUN" into the workplace, which everyone should strive for. It is also good to know that the skills you developusing Second Life or FaceBook can carry over to your next job role or your next employer.The number-one question I get from new colleagues when I mention either these exciting new ways to communicate and collaborate is: "But how is this related to business?"
Second Life is obvious, a new innovative way to hold meetings with colleagues, Business Partners and clients isgoing to have business value. Meetings in Second Life help you focus on what is being discussed, versus a plaintelephone call where your eyes may wander to other things in your view. Of course nothing beatsthe effectiveness of face-to-face meetings, but Second Life offers a more energy-efficient alternative than traveling to other cities or countries.
Stephen over at RupturedMonkey discusses the challenges of recruiting storage administrators:
There has been a Storage Admin job advertised for many months but no one wants it. Why? It's offering VERY good money but the word has got around the company has poor management practices and most people don't last for more than 6 months. So, with the shortage of good SAN people, good money and conditions, what can that company do to recruit someone? ...
This leads me to the thought that has anyone ever thought about the standards that storage administrators should follow? Can an employer look up a web site to find questions to ask prospective employees? More often than not, they are recruiting because the previous one left so how can companies know what they are getting.
There is actually a great standard called Information Technology Infrastructure Library (ITIL) that applies not just to storage administrators, but other IT personnel such as network administrators and server administrators. Here's a quick web-site about ITIL History:
ITIL History can be traced back to the late 1980’s when the British government determined that the level of IT service quality provided to them was not sufficient enough. The Central Computer and Telecommunications Agency (CCTA), now called the Office of Government Commerce (OGC), was tasked with developing a framework for efficient and financially responsible use of IT resources within the British government and the private sector.
The goal was to develop an approach that would be vendor-independent and applicable to organizations with differing technical and business needs. This resulted in the creation of the ITIL.
This standard spread from the UK to other governments in Europe, and is now being adopted worldwide by government agencies, non-profit organizations and commercial enterprises. IBM, of course, has been involved along the way, encouraging this set of best practices to take hold.
ITIL provides a common vocabulary that puts everyone in the IT industry on the same page, with the ultimate goal of helping companies run their IT organizations more efficiently.
ITIL provides recommendations, or best practices, for managing the way IT provides services to the rest of the organization, in the same way you would the rest of your business, with a defined set of processes.
While ITIL does a great job of describing what needs to be done, it doesn’t describe how to get it done. It doesn’t tell you how to take those best practices and implement them with real-life tools and technology. It’s not prescriptive.
The general process is now referred to as "IT Service Management", and the seven ITIL books are managed by the IT Service Management forum (ITSMf).
ITIL is vendor-independent. You can learn ITIL disciplines at one IT shop, and carry those skills with you when you go to another IT shop that has completely different gear. A common vocabulary would allow employers to post jobs in a consistent manner, and ask questions to those interviewing for the job. You can be ITIL-trained, and even ITIL-certified. IBM offers this training.
Of course, specific skills on how to use specific software to configure storage devices, request change control approvals, or define SAN zones, are useful, but often can be picked up on the job, reading the vendor manuals on the specifics. Of course, you can use IBM TotalStorage Productivity Center, which would allow someone to manage a variety of disk, tape and SAN fabric gear from one interface, greatly reducing the learning curve.
Some people find it surprising that it is often more cost-effective, and power-efficient, to run workloads on mainframe logical partitions (LPARs) than a stack of x86 servers running VMware.
Perhaps they won't be surprised any more. Here is an article in eWeek that explains how IBM isreducing energy costs 80% by consolidating 3,900 rack-optimized servers to 33 IBM System z mainframe servers, running Linux, in its own data centers. Since 1997, IBM has consolidated its 155 strategic worldwide data center locations down to just seven.
I am very pleased that IBM has invested heavily into Linux, with support across servers, storage, software andservices. Linux is allowing IBM to deliver clever, innovative solutions that may not be possible with other operating systems. If you are in storage, you should consider becoming more knowledgeable in Linux.
The older systems won't just end up in a landfill somewhere. Instead, the details are spelled out inthe IBM Press Release:
As part of the effort to protect the environment, IBM Global Asset Recovery Services, the refurbishment and recycling unit of IBM, will process and properly dispose of the 3,900 reclaimed systems. Newer units will be refurbished and resold through IBM's sales force and partner network, while older systems will be harvested for parts or sold for scrap. Prior to disposition, the machines will be scrubbed of all sensitive data. Any unusable e-waste will be properly disposed following environmentally compliant processes perfected over 20 years of leading environmental skill and experience in the area of IT asset disposition.
Whereas other vendors might think that some operational improvements will be enough, such as switching to higher-capacity SATA drives, or virtualizing x86 servers, IBM recognizes that sometimes more fundamental changes are required to effect real changes and real results.

I'm in Chicago this week, but it is actually HOTTER here than in my home town of Tucson, Arizona.
