Two weeks ago, I mentioned in my post [Pulse 2008 - Day 2 Breakout sessions
] thatHenk de Ruiter from ABN Amro bank presented his success storyimplementing Information Lifecycle Management (ILM) across hisvarious data centers. I am no stranger to ABN Amro, having helped "ABN" and "Amro" banks merge their mainframe data in 1991. Henk has agreed to let me share with my readers more ofthis success story here on my blog:
Back in December 2005, Henkand his colleagues had come to visit the IBM Tucson ExecutiveBriefing Center (EBC) to hear about IBM products and services. At the time, I was part of our "STG Lab Services" team that performed ILM assessments at client locations. I explained to ABN Amro that the ILM methodology does not requirean all-IBM solution, and that ILM could even provide benefits with their current mix of storage, software and service providers.The ABN Amro team liked what I had to say, andmy team was commissioned to perform ILM assessments atthree of their data centers:
- Amsterdam (Netherlands)
- Sao Paulo (Brazil)
- Chicago, IL (USA)
Each data center had its own management, its owndecision making, and its own set of issues, so we structuredeach ILM assessment independently. When we presented our results,we showed what each data center could do better with their existing mixed bagof storage, software and service providers, and also showed howmuch better their life would be with IBM storage, software andservices. They agreed to give IBM a chance to prove it, and soa new "Global Storage Study" was launched to take the recommendationsfrom our three ILM studies, and flesh out the details to make aglobally-integrated enterprise work for them. Once completed,it was renamed the "Global Storage Solution" (GSS).
Henk summarized the above with "I am glad to see Tony Pearsonin the audience, who was instrumental to making this all happen."As with many client testimonials, he presented a few charts onwho ABN Amro is today, the 12th largest bank worldwide, 8th largest in Europe. They operate in 53 countries and manage over a trillioneuros in assets.
They have over 20 data centers, with about 7 PB of disk, and over20 PB of tape, both growing at 50 to 70 percent CAGR. About 2/3 of theiroperations are now outsourced to IBM Global Services, the remaining 1/3is non-IBM equipment managed by a different service provider.
ABN Amro deployed IBM TotalStorage Productivity Center, variousIBM System Storage DS family disk systems, SAN Volume Controller (SVC), Tivoli StorageManager (TSM), Tivoli Provisioning Manager (TPM), and several other products. Armed with these products, they performed the following:
- Clean Up. IBM uses the term "rationalization" to relate to the assignment of business value, to avoid confusion with theterm "classification" which many in IT relate to identifyingownership, read and write authorization levels. Often, in theinitial phases of an ILM deployment, a portion of the data isdetermined to be eligible for clean up, either to move to a lower-cost tier or deleted immediately. ABN Amro and IBM set a goal to identifyat least 20 percent of their data for clean up.
- New tiers. Rather than traditional "storage tiers" which are often justTier 1 for Fibre Channel disk and Tier 2 for SATA disk, ABN Amroand IBM came up with seven "information infrastructure tiers" thatincorporate service levels, availability and protection status.They are:
- High-performance, Highly-available disk with Remote replication.
- High-performance, Highly-available disk (no remote replication)
- Mid-performance, high-capacity disk with Remote replication
- Mid-performance, high-capacity disk (no remote replication)
- Non-erasable, Non-rewriteable (NENR) storage employinga blended disk and tape solution.
- Enterprise Virtual Tape Library with remote replicationand back-end physical tape
- Mid-performance physical tape
These tiers are applied equally across their mainframe anddistributed platforms. All of the tiers are priced per "primary GB", so any additional capacity required for replication orpoint-in-time copies, either local or remote, are all folded into the base price.ABN Amro felt a mission-critical applicationon Windows or UNIX deserves the same Tier 1 service level asa mission-critical mainframe application. Exactly!
- Deployed storage virtualization for disk and tape. Thisinvolved the SAN Volume Controller and IBM TS7000 series library.
- Implemented workflow automation. The key product here is IBM Tivoli Provisioning Manager
- Started an investigation for HSM on distributed. This would be policy-based space management to migrate lessfrequently accessed data to the TSM pool for Windows or UNIX data.
While the deployment is not yet complete, ABN Amro feels they have alreadyrecognized business value:
- Reduced cost by identifying data that should be stored on lower tiers
- Simplified management, consolidated across all operating systems (mainframe, UNIX, Windows)
- Increased utilization of existing storage resources
- Reduced manual effort through policy-based automation, which can lead to fewer human errors and faster adaptability to new business opportunities
- Standardized backup and other operational procedures
Henk and the rest of ABN Amro are quite pleased with the progress so far,although recent developments in terms of the takeover of ABN AMRO by aconsortium of banks means that the model is only implemented so far in Europe. Further rollout depends on the storage strategy of the new owners. Nonetheless,I am glad that I was able to work with Henk, Jason, Barbara, Steve, Tom, Dennis, Craig and othersto be part of this from the beginning and be able to see it rollout successfully over the years.

I'm glad to be back home in Tucson for a few weeks. All of these conferences kept mefrom reading up with what was going on in the blogosphere.
A few of us at IBM found it odd that EMC would announce their new Geographically Dispersed Disaster Restart (GDDR) the weekBEFORE their "EMC World" conference. Why not announce all of the stuff all at once instead at the conference?Were they worried that the admission that "Maui" software is still many months awaythat much of a negative stigma? The decision probably went something like this:
EMCer #1: GDDR is finally ready, should we announce now, or wait ONE week to make it part of the thingswe announce at EMC World?
EMCer #2: We are not announcing much at EMC World and what people really want us to talk about, Maui, wearen't delivering for a while. Why can't people understand we are company of hardware engineers, not software programmers! So, better not be associated with that quagmire at all.
EMCer #1: Yes, boss, I see your point. We'll announce this week then.
My fellow blogger and intellectual sparring partner, Barry Burke, on his Storage Anarchist blog, posted [are you wasting money on your mainframe dr solution?"] to bringup the GDDR announcement. The key difference is that IBM GDPS works withIBM, EMC and HDS equipment, being the fair-and-balanced folks that IBM clientshave come to expect, but it appears EMC GDDR works only with EMC equipment.Because GDDR does less, it also costs less. I can accept that. You get whatyou pay for. Of course, IBM does have a variety of protection levels, one probably will meet your budget and your business continuity needs.
To correct Barry's misperception, companies that buy IBM mainframe servers do have a choice.They can purchase their operating system from IBM, get their Linux or OpenSolarisfrom someone else like Red Hat or Novell, or build their own OS distribution fromreadily available open source. And unlike other servers that might require at leastone OS partition from the vendor, IBM mainframes can run 100 percent Linux.GDPS supports a mix of OS data. z/OS and Linux data can all be managed by GDPS.Companies that own mainframes know this. I can forgive the misperception from Barry,as EMC is focused on distributed servers instead, and many in their company may not have muchexposure to mainframe technology, or have ever spoken to mainframe customers.
But what almost had me fall out of my chair was this little nugget from his post:
"If you're an IBM mainframe customer, you are - by definition - IBM's profit stream."
Honestly, is there anyone out there that does not realize that IBM is a for-profitcorporation? In contrast, Barry would like his readers to believe that EMC is selling GDDR at cost, andthat EMC is a non-profit organization. While IBM has been delivering actual solutions thatour clients want, EMC continues to rumor that someday they might get around to offering something worthwhile.In the last six months, the shareholders have interpreted both strategies for what they really are,and the stock prices reflect that:

The colors blue and red to represent IBM and EMC, respectively, were selected by Yahoo graph-making facility. The color red does not necessarily imply EMC is losing money or having financial troubles.)
Of course, I for one would love to help Barry's dream of EMC non-profitability come true. If anyone has any suggestions how we can help EMC approach this goal, please post a comment below.

Continuing my summary of Pulse 2008, the premiere service managementconference focusing on IBM Tivoli solutions, I attended and presentedbreakout sessions on Monday afternoon.
- Tivoli Storage "State-of-the-Subgroup" update
Kelly Beavers, IBM director of Tivoli Storage, presented the first breakout for all of the Tivoli Storage subgroup.Tivoli has several subgroups, but Tivoli Storage leads with revenuesand profits over all the others.Tivoli storage has top performing business partner channel of anysubgroup in IBM's Software Group division.IBM is world's #1 provider of storage vendor (hardware, softwareand services), so this came to no surprise to most of the audience.
Looking at just the Storage Software segment, it is estimatedthat customers will spend $3.5 billion US dollars more in the year 2011 than they did last year in 2007. IBM is #2 or #3 in eachof the four major categories: Data Protection, Replication, Infrastructure management, and Resource management. In eachcategory, IBM is growing market share, often taking away share fromthe established leaders.
There was a lot of excitement over the FilesX acquisition.I am still trying to learn more about this, but what I have gathered so far is that it can:
- Like turning a "knob", you can adjust the level of backupprotection from traditional discrete scheduled backups, to morefrequent snapshots, to continuous data protection (CDP). Inthe past, you often used separate products or features to dothese three.
- Perform "instantaneous restore" by performing a virtualmount of the backup copy. This gives the appearance that therestore is complete.
This year marks the 15th anniversary of IBM Tivoli StorageManager (TSM), with over 20,000 customers. Also, this yearmarks the 6th year for IBM SAN Volume Controller, having soldover 12,000 SVC engines to over 4,000 customers.
- Data Protection Strategies
Greg Tevis, IBM software architect for Tivoli Technical Strategy,and I presented this overview of data protection. We coveredthree key areas:
- Protecting against unethical tampering with Non-erasable, Non-rewriteable (NENR) storage solutions
- Protecting against unauthorized access with encryption ondisk and tape
- Protecting against unexpected loss or corruption with theseven "Business Continuity" tiers
There was so much interest in the first two topics that weonly had about 9 minutes left to cover the third! Fortunately,Business Continuity will be covered in more detail throughoutthe week.
- Business-Driven Storage
Henk de Ruiter from ABN Amro bank presented his success storyimplementing Information Lifecycle Management (ILM) across hisvarious data centers using IBM systems, software and services.
- Making your Disk Systems more Efficient and Flexible
I did not come up with the titles of these presentations. Theteam that did specifically chose to focus on the "business value"rather than the "products and services" being presented. Inthis session, Dave Merbach, IBM software architect, and I presentedhow SAN Volume Controller (SVC), TotalStorage Productivity Center,System Storage Productivity Center, Tivoli Provisioning Managerand Tivoli Storage Process Manager work to make your disk storagemore efficient and flexible.

I attended the main tent sessions on Day 2 (Monday). The focuswas on Visibility, Control and Automation.
- Steve Mills
Steve is IBM senior VP and Group Executive of the IBM Software Group, and presented someinsightful statistics from the IBM Global Technology Outlookstudy, some recent IBM wins, and other nuggets of IT trivia:
- In 2001, there were about 60 million transistors per humanbeing. By 2010, this is estimated to increase to one billion per human
- In 2005, there were about 1.3 billion RFID tags, by 2010this is estimated to grow to over 30 billion
- IBM helped the City of Stockholm, Sweden, reduce traffic congestion 20-25% using computer technology
- Only about 25% data is original, the remaining75% is replicated
- In 2007, there were approximately 281 Exabytes (EB), expected to increase to 1800 EB by the year 2011
- 70 percent of unstructured data is user-created content, but 85 percent of this will be managed by enterprises
- Only 20% of data is subject to compliance rules and standards, and about 30% subject to security applications
- Human error is the primary reason for breaches, with34% of organizations experiencing a major breach in 2006
- 10% of IT budget is energy costs (power and cooling), and thiscould rise to 50% in the next decade
- 30 to 60 percent of energy is wasted. During the next 5 years, people will spend as much on energy as they will on new hardware purchases.
- Al Zollar
Al Zollar is the General Manager of IBM Tivoli. He discussedthe 20 some recent software acquisitions, including Encentuate and FilesX earlier this year.
"The time has come to fully industrialize operations" -- Al Zollar
What did Al mean about "industrizalize"? This is theclosed-loop approach of continuous improvement, including design, delivery and management.
Al used several examples from other industries:
- Henry Ford used standardized parts and processautomation. Assembly of an automatobile went from 12 hours by master craftsmen, to delivering a new model T every 23 seconds off anassembly line.
- Power generation was developed by Thomas Edison. A satellite picture showed the extent of the [Blackout of 2003 in Northeast US and Canada]. The time for "smart grid" has arrived, making sensors andmeters more intelligent. This allows non-essential IP-enabled appliances in our home or office to be turned off to reduce energy consumption.
- [McCarran International Airport] integrated the management of 13,000 assets with IBM Tivoli Maximo Enterprise Asset Management (EAM) software, and was able to increase revenues through more accurate charge-back. Unlike traditional EnterpriseResource Planning (ERP) applications, EAM offers the deep management of four areas: production equipment, facilities, transportation, and IT.
When compared to these other industries, management of IT is in itsinfancy. The expansion of [Web 2.0] and Service-Oriented Architecture [SOA] is driving this need.What people need is a "new enterprise data center" that IBM Tivoli software can help you manage across operational boundaries. IBM can integrate through open standards with management software from Cisco, Sun, OracleMicrosoft, CA, HP, BMC Software, Alcatel Lucent, and SAP.Together with our ecosystems of technology partners, IBM ismeeting these challenges.
IBM clients have achieved return on investment from gettingbetter control of their environment. This week there are client experience presentations Sandia National Labs, Spirit AeroSystems, Bank of America, and BT Converged communication services.
- Live Demo
Chris O'Connor used some of his staff as "actors" to show an incredible live demo of various Tivoli and Maximo products for the mythical launch of "Project Vitalize", thenew online web store for a new "Aero Z bike" from the mythical VCA Bike and Motorcycle company.
Shoel Perelman played the role of "CIO".The CIO locked down all spending, and asked the IT staff to make the shift from bricks-and-mortar to web salesof this new product on in 15 months. While the company andsituation were mythical, all the products that were part of thelive demo are all readily available.The CIO had three goals:
What do we have? where is it? what's connected to what?Traditionally, these would be answered from lists in spreadsheets.The CIO had a goal to deploy IBM Tivoli Application DependenceDiscover Manager (TADDM) which discovered all hardware and software,with an easy to understand view, and how each piece serves the business applications.
Each of the teams have processes, and needed them consistent andrepeatable, tightly linked together. Time is often wasted on thephone coordinating IT changes. For this, the CIO had a goalto deploy Tivoli Change and Configuration Management Database (CCMDB) for "strict change control".The process dashboard is accessible for all teams, to see how all projects are progressing. There is also aCompliance dashboard, which identifies all changes by role, clearly spelling out who can do what.
There is a lot of computerized machinery, Manufacturing assets and robotics. The CIO set a goal to "do more with existing people", and needed to automate key processes.Sales rep wanted to add a new distributor to key web portal.This was all done through their "service catalog", When they needed to deploy a new application, they were able to find servers with available capacity and adjust using automatic provisioning. Thanks to IBM, the IT staff no longer get paged at 3am in the morning, and fewer days are spent in the "war room". They now have confidence that thelaunch will be successful.
Ritika Gunnar played the role of "Operations manager". She highlightedfive areas:
- "Service viewer" dashboard with green/yellow/red indicators forall of their edge, application and datbase servers. This allowsher to get data 4-5 times faster and more accurate.
- Tivoli Enterprise Portal eliminates bouncingaround various products.
- Tivoli Common Reporting for CPU utilization of all systems, helps find excess capacity usingIBM Tivoli Monitor
- On average, 85 percent of problems are caused by IT changes to the environment. IBM can help find dependencies, so that changes in one area do not impact other areas unexpectedly
- Process Automation will Show changes that have been completed, in progress, or overdue.She can see all steps in a task or change request. A"workflow" automates all the key steps that need to be taken.
Laura Knapp played the role of "Facilities manager". She wanted to See all processes that apply to her work using a role-based process dashboard. The advantage of using IBM is that it changes work habits, reduces overtimeby 42 percent, improves morale. The IT staff now works as team,collaborates more, and jobs get done faster with fewer mistakes.Employees are online, accessing, monitoring and managing dataquicker. In days not weeks.
IBM Tivoli Enterprise Console (TEP) served as a common vehicle.She was able to pull up floor plan online, displaying all of the managed assets and mapped features. With the temperature overlay from Maximo Spatial, she was able to review hot spots on data center floor. Heat can cause servers to fail or shut down.
Power utilization chart at peak loadsCan now anticipate, predict and watch power consumption,and were able to justify replacement with newer, more energy-efficient equipment.
The CIO got back on stage, and explained the great success of thelaunch. They use Webstore usage tracking, security tools tracking all new registrations, and trackingserver and storage load.It now only takes hours, not weeks, to add new business partners and distributors.Tivoli Service Quality Assurance toolstrack all orders placed, processed, and shipped.Faster responsiveness is competitive advantage. TheirIT department is no longer seen as stodgy group, but as a world classorganization.
The live demo showed how IBM can help clients with rapid decisionmaking, speed and accuracy of change processes, and automation to take actions quickly. The result is a strong return on investment (ROI).
- Liz Smith
Liz Smith, IBM General Manager of Infrastructure Services, presented the results of an IBM survey to CEOs and CIOs asking questions like: What is the next big impact? Where are you investing?What will new datacenter look like?
The five key traits they found for companies of the future:
- They were hungry for change
- Innovative beyond customer imagination
- Globally integrated
- Disruptive by nature
- Genuine, not just generous
The IT infrastructure must be secure, reliable, and flexible.Taking care of environment is a corporate responsibility, notjust a way to reduce costs.
The five entry points for IBM Service Management: Integrate, Industrialize,Discover,Monitor and Protect.IBM Service management and compliance are critical for theGlobally Integrated Enterprise, with repeatable, scalable and consistent processes that enablechange to an automated workflow. This reduces errors, risks and costs, and improves productivity.IBM has talent, assets and experience to help any client get there.
- Lance Armstrong
Lance lives in Austin, TX, where IBM Tivoli is headquartered,so this made a good choice as a keynote speaker.He is best known for winning seven "Tour de France" bicycle races in a row, but he spoke instead gave an inspirational talk about how he survived cancer.
In 1996, Lance was diagnosed with cancer. Surprisingly, He said it was thegreatest thing that happened to him, and gave him new perspective on his life, family and the sport ofbicycling.Back then, there wasn't a webMD, Google or other Web 2.0 socialnetworking sites for Lance to better understand what he wasgoing through, learn more about treatment options, or find othersgoing through the same ordeal.
After his treatment, he was considered "damaged goods" by manyof the leading European bicycle teams. So, he joined the US Postal Serviceteam, not known for their wins, but often invited to sell TVrights to American audiences. Collaborating with his coachesand other members of his team, he revolutionized the bicycling sport, analyzed everything about the race, and built up morale.He won the first "yellow jersey" in 1999, and did so each yearfor a total of seven wins.
Lance formed the [Livestrong foundation] to help other cancer survivors. Nike came to him and proposed donating 5 million "rubber bracelets"colored yellow to match his seven yellow jerseys, with the name "Livestrong" embossed on them, that his foundation couldthen sell for one dollar apiece to raise funds. What some thought was a silly idea at first has started amovement.At the 2004 Olympics, many athletes from all nations and religious backgrounds, wore these yellow braceletsto show solidarity with this cause.To date, the foundation has sold over 72 million yellow bracelets, and these have served to provide a symbol,a brand, a color identity, to his cause.
He explained that doctor's have a standard speech to cancer survivors.As a patient, you can go out this doorway and never tell anyone,keep the situation private. Or you can go out this other doorway, you tell everybody your story. Lance chose the latter, and he felt it was the best decision he ever made.He wrote a book titled [It's Not About the Bike: My Journey Back to Life].
His call to action for the audience: find out what can you do to make a difference.A million non-governmental organizations[NGO] have started in the past 10 years. Don't just give cash, also give your time and passion.
Lots of things to think about!

This is the second day of our Systems Technology Conference (STC08) in Los Angeles, California.We have over 700 break-out sessions, packed in 16 times slots across 47 rooms.
- IBM Strategy - the New Enterprise Data Center
In February, IBM launched its corporate-wide strategy for the "new enterprise data center", which I discussedalready in my post[Is your data center ready for the future?]
My session was the first in the morning, at 8:30am, but managed to pack the room full of people. A few looklike they just rolled in from Brocade's special get-together in Casey's Irish Pub the night before.I presented how IBM's storage strategy for the information infrastructure fits into the greater corporate-wide themes.To liven things up, I gave out copies of my book[Inside System Storage: Volume I] to those who asked or answered the toughest questions.
- Data Deduplication and IBM Tivoli Storage Manager (TSM)
IBM Toby Marek compared and contrasted the various data deduplication technologies and products available, andhow to deploy them as the repository for TSM workloads. She is a software engineer for our TSM software product,and gave a fair comparison between IBM System Storage N series Advanced Single Instance Storage (A-SIS), IBMDiligent, and other solutions out in the marketplace.If you are going to combine technologies, then it isbest to dedupe first, then compress, and finally encrypt the data. She also explained about the many cleverways that TSM does data reduction at the client side greatly reduces the bandwidth traffic over the LAN,as well as reducing disk and tape resources for storage. This includes progressive "incremental forever" backup for file selection, incremental backups for databases, and adaptive sub-file backup.Because of these data reduction techniques, you may not get as much benefit as deduplication vendors claim.
- The Business Value of Energy Efficiency Data Centers
Scott Barielle did a great job presenting the issues related to the Green IT data center. He is part of IBM"STG Lab Services" team that does energy efficiency studies for customers. It is not unusual for his teamto find potential savings of up to 80 percent of the Watts consumed in a client's data center.
IBM has done a lot to make its products more energy efficient. For example, in the United States, most datacenters are supplied three-phase 480V AC current, but this is often stepped down to 208V or 110V with powerdistribution units (PDUs). IBM's equipment allows for direct connection to this 480V, eliminating the step-downloss. This is available for the IBM System z mainframe, the IBM System Storage DS8000disk system, and larger full-frame models of our POWER-based servers, and will probably be rolled out to someof our other offerings later this year. The end result saves 8 to 14 percent in energy costs.
(Last October, IBM Randy Malik made a similar case in his presentation:[HighVoltage Distributions])
Scott had some interesting statistics. Typical US data centers only spend about 9 percent of their IT budgeton power and cooling costs. The majority of clients that engage IBM for an energy efficiency study are not tryingto reduce their operational expenditures (OPEX), but have run out, or close to running out, of total kW ratingof their current facility, and have been turned down by their upper management to spend the average $20 million USDneeded to build a new one. The cost of electricity in the USA has risen very slowly over the past 35 years, andis more tied the to fluctuations of Natural Gas than it is to Oil prices.(a recent article in the Dallas News confirmed this:["As electricity rates go up, natural gas' high prices, deregulation blamed"])
- Cognos v8 - Delivering Operational Business Intelligence (BI) on Mainframe
Mike Biere, author of the book [BusinessIntelligence for the Enterprise], presented Cognos v8 and how it is being deployed for the IBMSystem z mainframe. Typically, customers do their BI processing on distributed systems, but 70 percent of the world's business data is on mainframes, so it makes sense to do yourBI there as well. Cognos v8 runs on Linux for System z, connecting to z/OS via [Hypersockets].
There are a variety of other BI applications on the mainframe already, including DataQuant,AlphaBlox, IBI WebFocus and SAS Enterprise Business Intelligence. In addition to accessing traditional onlinetransaction processing (OLTP) repositories like DB2, IMS and VSAM, using the [IBM WebSphere ClassicFederation Server], Cognos v8 can also read Lotus databases.
Business Intelligence is traditionally query, reporting and online analytics process (OLAP) for the top 10 to 15 percent of the company, mostly executives andanalysts, for activities like business planning, budgeting and forecasting. Cognos PowerPlay stores numericaldata in an [OLAP cube] for faster processing.OLAP cubes are typically constructed with a batch cycle, using either "Extract, Transfer, Load" [ETL], or "Change Data Capture" [CDC], which playsto the strength of IBM System z mainframe batch processing capabilities.If you are not familiar with OLAP, Nigel Pendse has an article[What is OLAP?] for background information.
Over the past five years, BI is now being more andmore deployed for the rest of the company, knowledge workers tasked with doing day-to-day operations. Thisphenomenom is being called "Operational" Business Intelligence.
For more on this, see the IBM Systems Magazine article [Upgrade Your Mainframe with Operational Business Intelligence].
- IBM GPFS - Fundamentals and What's New
IBM Glen Corneau, who is on the Advanced Technical Support team for AIX and System p, presented the IBMGeneral Parellel File System (GPFS), which is available for AIX, Linux-x86 and Linux on POWER.Unfortunately, many of the questions were related to Scale Out File Services (SOFS), which my colleague GlennHechler was presenting in another room during this same time slot.
GPFS is now in its 11th release since its introducing in 1997. All of the IBM supercomputers on the [Top 500 list] use GPFS. The largest deployment of GPFS is 2241 nodes.A GPFS environment can support up to 256 file systems, each file system can have up to 2 billion filesacross 2 PB of storage. GPFS supports "Direct I/O" making it a great candidate for Oracle RAC deployments.Oracle 10g automatically detects if it is using GPFS, and sets the appropriate DIO bits in the stream totake advantage of GPFS features.
Glen also covered the many new features of GPFS, such as the ability to place data on different tiers ofstorage, with policies to move to lower tiers of storage, or delete after a certain time period, all conceptswe call Information Lifecycle Management. GPFS also supports access across multiple locations and offersa variety of choices for disaster recovery (DR) data replication.
Perhaps the only problem with conferences like this is that it can be an overwhelming["fire hose"] of information!

While HDS blogger Hu Yoshida and IBM blogger Barry Whyte make a [great case for why you should buy IBM SAN Volume Controller
], my favorite arch-nemesis and fellow blogger BarryB on his Storage Anarchist
blog feels the SVC is "blue spray paint".
BarryB's latest round of red-meat rhetoric is his amusing post [This is like déjà vu all over again], titled after a [quote from Yogi Berra].BarryB pokes fun at Andy Monshaw's commentsin Chris Preimesberger's eWeek article [IBM's Big Storage Picture], andmy post ealier this week about Sun's "Open Storage" initiative [Simply Dinners and Open Storage from Sun], as if the two were somehow connected.
He feels I was unfair to accuse EMC of "proprietary interfaces" without spelling out what I was referring to. Here arejust two, along with the whines we hear from customers that relate to them.
- EMC Powerpath multipathing driver
Typical whine: "I just paid a gazillion dollars to renew my annual EMC Powerpath license, so you will have to come back in 12 months with your SVC proposal. I just can't see explaining to my boss that an SVC eliminates the need for EMC Powerpath, throwing away all the good money we just spent on it, or to explain that EMC chooses not to support SVC as one of Powerpath's many supported devices."
- EMC SRDF command line interface
Typical whine: "My storage admins have written tons of scripts that all invoke EMC SRDF command line interfacesto manage my disk mirroring environment, and I would hate for them to re-write this to use IBM's (also proprietary) command line interfaces instead."
Certainly BarryB is correct that IBM still has a few remaining "proprietary" items of its own. IBM has been in business over 80 years, but it was only the last 10-15 years that IBM made a strategic shift away from proprietary and over to open standards and interfaces. The transformation to "openness" is not yet complete, but we have made great progress. Take these examples:
- The System z mainframe - IBM had opened the interfaces so that both Amdahl and Fujitsu made compatible machines.Unlike Apple which forbids cloning of this nature, IBM is now the single source for mainframes because the other twocompetitors could not keep up with IBM's progress and advancements in technology.
Update: Due to legal reasons, the statements referring to Hercules and other S/390 emulators havebeen removed.
- The z/OS operating system - While it is possible to run Linux on the mainframe, most people associate the z/OSoperating system with the mainframe. This was opened up with UNIX System Services to satisfy requests from variousgovernments. It is now a full-fledged UNIX operating system, recognized by the [Open Group] that certifies it as such.
- As BarryB alludes, the unique interfaces for disk attachment to System z known as Count-Key-Data (CKD) was published so that both EMC and HDS can offer disk systems to compete with IBM's high-end disk offerings. Linux on System zsupports standard Fibre Channel, allowing you to attach an IBM SVC and anyone's storage. Both z/OS and Linux on System z support NAS storage, so IBM N series, NetApp, even EMC Celerra could be used in that case.
- The System i itself is still proprietary, but recently IBM announced that it will now support standard block size (512 bytes) instead of the awkward 528 byte blocks that only IBM and EMC support today. That means that any storage vendor will be ableto sell disk to the System i environment.
- Advanced copy services, like FlashCopy and Metro Mirror, are as proprietary as the similar offerings from EMCand HDS, with the exception that IBM has licensed them to both EMC and HDS. Thanks to cross-licensing, you can do [FlashCopy on EMC] equipment. Getting all the storage vendors to agree to open standards for these copy services is still workin progress under [SNIA], but at least people who have coded z/OS JCL batchjobs that invoke FlashCopy utilities can work the same between IBM and EMC equipment.
So for those out there who thought that my comment about EMC's proprietary interfaces in any way implied thatIBM did not have any of its own, the proverbial ["pot calling the kettle black"] so to speak, I apologize.
BarryB shows off his [PhotoShop skills] with the graphic below. I take it as a compliment to be compared to anAll-American icon of business success.
|TonyP and Monopoly's Mr. Pennybags|
Separated at Birth?
However, BarryB meant it as a reference back to long time ago when IBMwas a monopoly of the IT industry, which according to [IBM's History
], ended in 1973. In other words, IBMstopped being a monopoly before EMC ever existed as a company, and long before I started working for IBM myself.
The anti-trust lawsuit that BarryB mentions happened in 1969, which forced IBM to separate some of the software from its hardware offerings, and prevented IBM from making various acquisitions for years to follow, forcing IBM instead into technology partnerships. I'm glad that's all behind us now!

I've talked to several customers who have taken up the bad habit of keeping their backup copiesfor several years for "compliance reasons".
In my post last year [Lost In Translation], I talked about the different meanings of archive:
In explaining the word "archive" we came up with two separate Japanese words. One was "katazukeru", and the other was "shimau". If you are clearing the dinner plates from the table after your meal, for example, it could be done for two reasons. Both words mean "to put away", but the motivation that drives this activity changes the word usage. The first reason, katazukeru, is because the table is important, you need the table to be empty or less cluttered to use it for something else, perhaps play some card game, work on arts and craft, or pay your bills. The second reason, shimau, is because the plates are important, perhaps they are your best tableware, used only for holidays or special occasions only, and you don't want to risk having them broken. As it turns out, IBM supports both senses of the word archive. We offer "space management" when the space on the table, (or disk or database), is more important, so older low-access data can be moved off to less expensive disk or tape. We also offer "data retention" where the data itself is valuable, and must be kept on WORM or non-erasable, non-rewriteable storage to meet business or government regulatory compliance.
The process of archiving your data from primary disk to alternate storage media can satisfy both motivations.
IBM offers software specifically to help with this archival process.For email archive, IBM offers [IBM CommonStore] for Lotus Domino and MicrosoftExchange. For database archive, including support for various ERP and CRM applications, IBM offers [IBM Optim] from the acquisition of Princeton Softech.
The problems occur when companies, under the excuse of simplification or consolidation, feel they can just usetheir backups as archives. They are taking daily backups of their email repositories and databases, and keepingthese for seven to ten years. But what happens when their legal e-discovery team needs to find all emails or database records related to a particular situation, an employee, client or account? Good luck! Most backupsare not indexed for this purpose, so storage admins are stuck restoring many different backups to temporary storage and combing through the files in hopes to find the right data.
Backups are intended for operational recovery of data that is lost or corrupted as a result of hardware failures, application defects, or human error. Disk mirroring or remote replication might help with hardware failures, but any logical deletion or corruption of data is immediately duplicated, so it is not a complete solution. FlashCopy or Snapshot point-in-time copies are useful to go back a short time to recover from logical failures, but since they are usually on the same hardware as the original copies, may not protect against hardware failures. And then there's tape, and while many people malign tape as a backup storage choice, 71 percent of customers send backups to tape, according to a 2007 Forrester Research report.
Backups often aren't viable unless restored to the same hardware platform, with the same operating system and application software to make sense of the ones and zeros. For this reason, people typically only keep two to five backup versions, for no more than 30 days, to support operational recovery scenarios. If you make updatesto your hardware, OS or application software, be sure to remember to take fresh new backups, as the old backupsmay no longer apply.
Archives are different. Often, these are copies that have been "hardened" or "fossilized" so that they make sense even if the original hardware, OS or application software is unavailable. They might be indexed so that they can be searched, so that you only have to retrieve exactly the data you are looking for. Finally, they are often stored with "rendering tools" that are able to display the data using your standard web browser, eliminating the need to have a fully working application environment.
Take any backup you might have from five years ago and try to retrieve the information. Can you do it? This might be a real eye-opener. You might have inherited this backup-as-also-archive approach from someone else, and are trying to figure out what to do differently that makes more sense. Call IBM, we can help.

I am always amused in the manner the IT industry tries to solve problems. Take, for example, theprocess of backups. The simplest approach is to backup everything, and keep "n" versions of that.Simple enough for a small customer who has only a handful of machines, but does not scale well. Inmy post [Times a Million
],I coined the phrase "laptop mentality", referring to people's inability to think through solutions in large scale.
Apparently, I am not alone.Steve Duplessie (ESG) wrote in his post[Random Thoughts]:
"I may even get to stop yelling at people to stop doing full backups every week on non-changing data (which is 80 %+) just because that's how they used to do it. They won't have a choice. You can't back up 5X your current data the way you do (or don't) today."
Hu Yoshida (HDS) does a great job explaining that thereare three ways to perform deduplication for backups:
- Pre-processing. Have the backup software not backup unchanged data.
- Inline processing. Have an index to filter the output of the backup as it sends data to storage.
- Post-processing. Have the receiving storage detect duplicates and handle them accordingly.
Here's an excerpt from his post[Deduplication Ratios]:
"A full backup of 1TB data base tablespace is taken on day one. The next day another full backup is taken and only 2GB of that backup has any changes.
Using traditional full backup approaches after 2 nights, the backup capacity required is 2 x 1TB = 2TB
One method of calculating de-duplication ratios could yield a low ratio:
- Total de-duplicated backup capacity used = 1TB + 2GB = 1.002TB
- If the de-duplication ratio compares the amount of total physical storage used to the total amount that would have been used by traditional backup methods, the ratio = 2TB / 1.002TB = approximately 2:1
Another method of calculating de-duplication ratios could yield a high ratio:
- Total de-duplicated backup capacity used still = 1.002TB
- If the de-duplication ratio compares the amount of data stored in the most recent (second) backup to the amount that would have been used by traditional backup methods, the ratio 1TB / 2GB = 1000GB / 2GB = 500:1"
While IBM also offers deduplication in the IBM System Storage N series disk systems, I find that for backup, itis often more effective to apply best practices via IBM Tivoli Storage Manager (TSM). Let's take a look at some:
- Exclude Operating System files
Why take full backups of your operating system every day? Yes, deduplication will find a lot to reduce fromthis, but best practices would exclude these. TSM has an include/exclude list, and the default version excludesall the operating system files that would be recovered from "bare machine recovery" or "new system install"procedures. Often, if the replacement machine has different gear inside, your OS backups aren't what you need,and a fresh OS install may determine this and install different drivers or different settings.
- Exclude Application programs
Again, yes if there are several machines running the same application, you probably have opportunity for deduplication. However, unless you match these up with the appropriate registry or settings buried down in theoperating system, recovering just application program files may render an unusable system. Applications are bestinstalled from a common source that are either "pushed" through software distribution, or "pulled" from an application installation space.
If you have TB-sized databases, and are only doing full backups daily to protect it, have I got a solution for you.IBM and others have software that are "application-aware" and "database-aware" enough to determine what haschanged since the last backup and copy only that delta. Taking advantage of the TSM Application ProgrammingInterface (API) allows for both IBM and third party tools to take these delta backups correctly.
- User Files
Which leaves us with user files, which are often unique enough on their own from the files of other users,that would not benefit from file-level deduplication. Backing up changed data only, as TSM does with its patented ["progressive incremental backup"] method, generally gets most of the benefits described by deduplication, without having to purchase storage hardware features.
Of course, if two or more users have identical files, the question might be why these are not stored on acommon file share. NAS file share repositories can greatly reduce each user keeping their own set of duplicates.It is interesting that some block-oriented deduplication,such as that found in the IBM System Storage N series, can get some benefit because some user files are oftenderivatives of other files, and there might be some 4 KB blocks of data in common.
Last November, I visited a customer in Canada. All of their problems were a direct result of taking full backupsevery weekend. It put a strain on their network; it used up too many disk and tape resources; and it took too long tocomplete. They asked about virtual tape libraries, deduplication, and anything else that could help them. The answer was simple: switch to IBM Tivoli Storage Manager and apply best practices.

On Tuesday, I covered much of the Feb 26 announcements, but left the IBM System Storage DS8000 for today so that it can haveits own special focus.
Many of the enhancements relate to z/OS Global Mirror, which we formerly called eXtended Remote Copy or "XRC", not to be confused with our "regular" Global Mirror that applies to all data. For those not familiar with z/OS Global Mirror, here is how it works. The production mainframe writes updates to the DS8000, and the DS8000 keeps track of these in cache until a "reader" can pull them over to the secondary location.The "reader" is called System Data Mover (SDM) which runs in its own address space under z/OS operating system. Thanks to some work my team did several years ago, z/OS Global Mirror was able to extend beyond z/OS volumes and include Linux on System z data. Linux on System z can use a "Compatible Disk Layout" (CDL) format (now the default) that meetsall the requirements to be included in the copy session.
IBM has over 300 deployments of z/OS Global Mirror, mostly banks, brokerages and insurance companies. The feature can keep tens of thousands of volumes in one big "consistency group" and asynchronously mirror them to any distance on the planet, with the secondary copy recovery point objective (RPO) only a few seconds behind the primary.
- Extended Distance FICON
Extended Distance FICON is an enhancement to the industry-standard FICON architecture (FC-SB-3) that can help avoid degradation of performance at extended distances by implementing a new protocol for "persistent" Information Unit (IU) pacing. This deals with the number of packets in flight between servers and storage separated by long distances, andcan keep a link fully utilized at 4Gpbs FICON up to 50 kilometers. This is particularly important for z/OS GlobalMirror "reader" System Data Mover (SDM). By having many "reads" in flight, this enhancementcan help reduce the need for spoofing or channel-extender equipment, or allow you to choose lower-costchannel extenders based on "frame-forwarding" technology. All of this helps reduce your total cost of ownership (TCO)for a complete end-to-end solution.
This feature will be available in March as a no-charge update to the DS8000 microcode.For more details, see the [IBM Press Release]
- z/OS Global Mirror process offload to zIIP processors
To understand this one, you need to understand the different "specialty engines" available on the System z.
On distributed systems where you run a single application on a single piece of server hardware, you mightpay "per server", "per processor" or lately "per core" for dual-core and quad-core processors. Software vendors were looking for a way to charge smaller companies less, and larger companies more. However, you might end up paying the same whether you use 1GHz Intelor 4GHz Intel processor, even though the latter can do four times more work per unit time.
The mainframe has a few processors for hundreds or thousands of business applications.In the beginning, all engines on a mainframe were general-purpose "Central Processor" or CP engines. Based on theircycle rate, IBM was able to publish the number of Million Instructions per Second (MIPS) that a machine witha given number of CP engines can do. With the introduction of side co-processors, this was changed to "Millionsof Service Units" or MSU. Software licensing can charge per MSU, and this allows applications running in aslittle as one percent of a processor to get appropriately charged.
One of the first specialty engines was the IFL, the "Integrated Facility for Linux". This was a CP designatedto only run z/VM and Linux on the mainframe. You could "buy" an IFL on your mainframe much cheaper than a CP,and none of your z/OS application software would count it in the MSU calculations because z/OS can't run on theIFL. This made it very practical to run new Linux workloads.
In 2004, IBM introduced "z Application Assist Processor" (zAAP) engines to run Java, and in 2006, the "z Integrated Information Processor" (zIIP) engines to run database and background data movement activities.By not having these counted in the MSU number for business applications, it greatly reduced the cost for mainframe software.
Tuesday's announcement is that the SDM "reader" will now run in a zIIP engine, reducing the costs for applicationsthat run on that machine. Note that the CP, IFL, zAAP and zIIP engines are all identical cores. The z10 EC hasup to 64 of these (16 quad-core) and you can designate any core as any of these engine types.
- Faster z/OS Global Mirror Incremental Resync
One way to set up a 3-site disaster recovery protection is to have your production synchronously mirrored to a second site nearby, and at the same time asynchronously mirrored to a remote location. On the System z,you can have site "A" using synchronous IBM System Storage Metro Mirror over to nearby site "B", and alsohave site "A" sending data over to size "C" using z/OS Global Mirror. This is called "Metro z/OS Global Mirror"or "MzGM" for short.
In the past, if the disk in site A failed, you would switch over to site B, and then send all the data all over again. This is because site B was not tracking what the SDM reader had or had not yet processed.With Tuesday's announcement, IBM has developed an "incremental resync" where site B figures out what theincremental delta is to connect to the z/OS Global Mirror at site "C", and this is 95% faster than sendingall the data over.
- IBM Basic HyperSwap for z/OS
What if you are sending all of your data from one location to another, and one disk system fails? Do you declare a disaster and switch over entirely? With HyperSwap, you only switch over the disk systems, but leave therest of the servers alone. In the past, this involved hiring IBM Global Technology Services to implementa Geographically Dispersed Parallel Sysplex (GDPS) with software that monitors the situation and updates thez/OS operating system when a HyperSwap had occurred. All application I/O that were writing to the primary locationare automatically re-routed to the disks at the secondary location. HyperSwap can do this for all the disk systems involved,allowing applications at the primary location to continue running uninterrupted.
HyperSwap is a very popular feature, but not everyone has implemented the advanced GDPS capabilities.To address this, IBM now offers "Basic HyperSwap", which is actually going to be shipped as IBMTotalStorage Productivity Center for Replication Basic Edition for System z. This will run in a z/OSaddress space, and use either the DB2 RDBMS you already have, or provide you Apache Derby database for thosefew out there who don't have DB2 on their mainframe already.
Update: There has been some confusion on this last point, so let me explain the keydifferences between the different levels of service:
- Basic HyperSwap: single-site high availability for the disk systems only
- GDPS/PPRC HyperSwap Manager: single- or multi-site high availability for the disk systems, plus some entry-level disaster recovery capability
- GDPS/PPRC: highly automated end-to-end disaster recovery solution for servers, storage and networks
I apologize to all my colleagues who thought I implied that Basic HyperSwap was a full replacement for the morefull-function GDPS service offerings.
- Extended Address Volumes (EAV)
Up until now, the largest volume you could have was only 54 GB in size, and many customers still are using 3 GB and 9 GB volume sizes. Now, IBM will introduce 223 GB volumes. You can have any kind of data set on these volumes,but only VSAM data sets can reside on cylinders beyond the first 65,280. That is because many applications still thinkthat 65,280 is the largest cylinder number you can have.
This is important because a mainframe, or a set of mainframes clustered together, can only have about 60,000disk volumes total. The 60,000 is actually the Unit Control Block (UCB) limit, and besides disk volumes, youcan have "virtual" PAVs that serve as an alias to existing volumes to provide concurrent access.
Aside from the first item, the Extended Distance FICON, the other enhancements are "preview announcements" which means that IBM has not yet worked out the final details of price, packaging or delivery date. In many cases, the work is done, has been tested in our labs, or running beta in select client locations, but for completeness I am required to make the following disclaimer:
All statements regarding IBM's plans, directions, and intent are subject to change or withdrawal without notice. Availability, prices, ordering information, and terms and conditions will be provided when the product is announced for general availability.
