Today was the "First Ever Live Virtual Virtualization Tech Fair" sponsored by IBM and VMware. This was a 1-day event hosted by Unisfair.
The day included presentations done at a conference call, along with exhibition booths.
We had an exhibition booth exclusively for "storage virtualization" featuring our IBM System Storage SAN Volume Controller (disk virtualization) and IBM System Storage TS7520 Virtualization Engine (a virtual tape library, or VTL).
People who were logged in were represented in silhouette form. When someone walked into the booth, our army of "booth reps" were able to chat with them and answer their questions. They could also peruse the various online materials we made available about each product.
Here are some of my observations:

In case you haven't noticed, IBM System Storage makes most of their announcements on Tuesdays. IBM announced a lot today, so here is a quick run-down.
IBM continues its market leadership with these new set of features and offerings!

One of the differences between IBM and the other storage vendors is that IBM is also in the business of middleware, application-aware backup software, and advanced copy services. This allows IBM to put togethersolutions that work to address specific challenges for our clients.
IBM has written a whitepaper on a cleverVSS Snapshot Backup for Exchange using IBM Tivoli Storage Manager and the point-in-time copy capabilities of IBM System Storage disk systems.
A problem in the past was that each vendor's point-in-time copy method had its own unique proprietary interface.Microsoft Developed Volume Shadow Copy Services (VSS) as a common interface front-end to resolve this concern.IBM Tivoli Storage Manager for Mail can invoke standard VSS interfaces, and this in turn can invoke FlashCopyon the IBM System Storage SAN Volume Controller, DS8000 series, or DS6000 series disk system.
You might be thinking: Wouldn't it have been less effort to just have TSM for Mail invoke IBM proprietary interfaces,rather than having to put full VSS support into TSM for mail, and then full VSS support into IBM's various disksystems? Perhaps, but IBM doesn't decide to do things because it is the cheapest way, we focus on what is theright way, and in this case, customers now have more choices, then can use TSM for Mail with IBM or non-IBM disksystems that support the VSS interface, and IBM disk systems can be employed into other uses for VSS snapshot.
Of course, we would like our clients to consider both TSM and IBM System Storage disk systems for a combined solution,not because they are required to make the solution work, but because both are best-of-breed, and whitepapers likethis show how they can provide synergy working together.
There's some good discussion in the comments section over at Robin Harris' StorageMojo blog for hispost [Building a 1.8 Exabyte Data Center].To summarize, a student is working on a research archive and asked Robin Harris for his opinion. The archive will consist of 20-40 million files averaging 90 GB in size each, for a total of 1800 PB or 1.8 EB. By comparison, anIBM DS8300 with five frames tops out at 512TB, so it would take nearly 3600 of these to hold 1.8 EB. While this might seem like a ridiculous amount of data, I think the discussion is valid as our world is certainly headed in that direction.
IBM works with a lot of research firms, and the solution is to put most of this data on tape, with just enough disk for specific analysis. Robin mentions a configurion with Sun Fire 4540 disk systems (aka Thumper). Despite Sun Microsystems' recent [$1.7 Billion dollar quarterly loss], I think even the experts at Sun would recommend a blended disk-and-tape solution for this situation.
Take for example IBM's Scale Out File Services [SoFS] which today handles 2-3 billion files in a single global file system, so 20-40 million would present no problem. SoFS supports a mix of disk and tape, with built-in movement, so that files that were referenced would automatically be moved to disk when needed, and moved back to tape when no longer required, based on policies set by the administrator. Depending on the analysis, you may only need 1 PB or less of disk to perform the work, which can easily be accomplished with a handful of disk systems, such as IBM DS8300 or IBM XIV, for example.
The rest would be on tape. Let's consider using the IBM TS3500 with [S24 High Density] frames. A singleTS3500 tape library with fifteen of these HD frames could hold 45PB of data, assuming 3:1 compression on 1TB-size 3592 cartridges. You wouldneed 40 (forty) of these libraries to get to the full 1800 PB required, and these could hold even more as higher capacity cartridges are developed. IBM has customers with over 40 tape libraries today (not all with these HD frames, of course), but the dimensions and scale that IBM is capable lies within this scope.
(For LTO fans, fifteen S54 frames would hold 32PB of data, assuming 2:1 compression on 800GB-size LTO-4 cartridges.so you would need 57 libraries instead of 40 in the above example.)
This blended disk-and-tape approach would drastically reduce the floorspace and electricity requirements when compared against all-disk configurations discussed in the post.
People are rediscovering tape in a whole new light. ComputerWorld recently came out with an 11-page Technology Brief titled [The Business Value of Tape Storage],sponsored by Dell. (Note: While Dell is a competitor to IBM for some aspects of their business, they OEM their tape storage systems from IBM, so in that respect, I can refer to them as a technology partner.) Here are some excerpts from the ComputerWorld brief:
For IT managers, the question isnot whether to use tape, but whereand how to best use tape as part of acomprehensive, tiered storage architecture.In the modern storage architecture,tape plays a role not onlyin data backup, but also in long-termarchiving and compliance.
So, whether you are planning for an Exabyte-scale data center, or merely questioning the logic of a disk-for-everything storage approach, you might want to consider tape. It's "green" for the environment, and less expensive on your budget.

Once again it's Tuesday, which means IBM announcement day!
Today IBM announced [two new DS3400 SAN Express Models]. These two new models will replace the IBM System Storage DS3400 SAN Express Kit model 41U and 42U to be withdrawn from marketing today. The DS3000 series of scalable, flexible, and affordable storage solutions support IBM System x, System p, and BladeCenter servers.
Two new IBM System Storage DS3400 SAN Express Kits are being introduced that provide the parts needed to setup and configure a SAN with the exception of a SAN switch that can be ordered separately. The IBM System Storage DS3400 SAN Express Kits contain Emulex EZPilot software that enables automated installation and configuration of the SAN components. IBM System Storage DS3400 SAN Express Kits models 41S and 42S and Emulex EZPilot software work in conjunction with the IBM TotalStorage SAN16B-2 Express Model Switch which comes with eight ports and eight 4 Gbps SFPs. The EZPilot software can support configurations with either one or two SAN16B-2 switches.
The 41S is a single-controller model DS3400 with two HBA cards and four cables. The 42S is the dual-controller model with two HBA cards and eight cables.Read More]
