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.
