Well, it's Tuesday again, but this time, today we had our third big storage launch of 2009! A lot got announced today as part of IBM's big "Dynamic Infrastructure" marketing campaign. I will just focus on the
disk-related announcements today:
IBM System Storage DS8700
IBM adds a new model to its DS8000 series with the
[IBM System Storage DS8700]. Earlier this month, fellow blogger and arch-nemesis Barry Burke from EMC posted [R.I.P DS8300] on this mistaken assumption that the new DS8700 meant that DS8300 was going away, or that anyone who bought a DS8300 recently would be out of luck. Obviously, I could not respond until today's announcement, as the last thing I want to do is lose my job disclosing confidential information. BarryB is wrong on both counts:
IBM will continue to sell the DS8100 and DS8300, in addition to the new DS8700.
Clients can upgrade their existing DS8100 or DS8300 systems to DS8700.
BarryB's latest post [What's In a Name - DS8700] is fair game, given all the fun and ridicule everyone had at his expense over EMC's "V-Max" name.
So the DS8700 is new hardware with only 4 percent new software. On the hardware side, it uses faster POWER6 processors instead of POWER5+, has faster PCI-e buses instead of the RIO-G loops, and faster four-port device adapters (DAs) for added bandwidth between cache and drives. The DS8700 can be ordered as a single-frame dual 2-way that supports up to 128 drives and 128GB of cache, or as a dual 4-way, consisting of one primary frame, and up to four expansion frames, with up to 384GB of cache and 1024 drives.
Not mentioned explicitly in the announcements were the things the DS8700 does not support:
ESCON attachment - Now that FICON is well-established for the mainframe market, there is no need to support the slower, bulkier ESCON options. This greatly reduced testing effort. The 2-way DS8700 can support up to 16 four-port FICON/FCP host adapters, and the 4-way can support up to 32 host adapters, for a maximum of 128 ports. The FICON/FCP host adapter ports can auto-negotiate between 4Gbps, 2Gbps and 1Gbps as needed.
LPAR mode - When IBM and HDS introduced LPAR mode back in 2004, it sounded like a great idea the engineers came up with. Most other major vendors followed our lead to offer similar "partitioning". However, it turned out to be what we call in the storage biz a "selling apple" not a "buying apple". In other words, something the salesman can offer as a differentiating feature, but that few clients actually use. It turned out that supporting both LPAR and non-LPAR modes merely doubled the testing effort, so IBM got rid of it for the DS8700.
Update: I have been reminded that both IBM and HDS delivered LPAR mode within a month of each other back in 2004, so it was wrong for me to imply that HDS followed IBM's lead when obviously development happened in both companies for the most part concurrently prior to that. EMC was late to the "partition" party, but who's keeping track?
Initial performance tests show up to 50 percent improvement for random workloads, and up to 150 percent improvement for sequential workloads, and up to 60 percent improvement in background data movement for FlashCopy functions. The results varied slightly between Fixed Block (FB) LUNs and Count-Key-Data (CKD) volumes, and I hope to see some SPC-1 and SPC-2 benchmark numbers published soon.
The DS8700 is compatible for Metro Mirror, Global Mirror, and Metro/Global Mirror with the rest of the DS8000 series, as well as the ESS model 750, ESS model 800 and DS6000 series.
New 600GB FC and FDE drives
IBM now offers [600GB drives] for the DS4700 and DS5020 disk systems, as well as the EXP520 and EXP810 expansion drawers. In each case, we are able to pack up to 16 drives into a 3U enclosure.
Personally, I think the DS5020 should have been given a DS4xxx designation, as it resembles the DS4700
more than the other models of the DS5000 series. Back in 2006-2007, I was the marketing strategist for IBM System Storage product line, and part of my job involved all of the meetings to name or rename products. Mostly I gave reasons why products should NOT be renamed, and why it was important to name the products correctly at the beginning.
IBM System Storage SAN Volume Controller hardware and software
Fellow IBM master inventory Barry Whyte has been covering the latest on the [SVC 2145-CF8 hardware]. IBM put out a press release last week on this, and today is the formal announcement with prices and details. Barry's latest post
[SVC CF8 hardware and SSD in depth] covers just part of the entire
The other part of the announcement was the [SVC 5.1 software] which can be loaded
on earlier SVC models 8F2, 8F4, and 8G4 to gain better performance and functionality.
To avoid confusion on what is hardware machine type/model (2145-CF8 or 2145-8A4) and what is software program (5639-VC5 or 5639-VW2), IBM has introduced two new [Solution Offering Identifiers]:
5465-028 Standard SAN Volume Controller
5465-029 Entry Edition SAN Volume Controller
The latter is designed for smaller deployments, supports only a single SVC node-pair managing up to
150 disk drives, available in Raven Black or Flamingo Pink.
EXN3000 and EXP5060 Expansion Drawers
IBM offers the [EXN3000 for the IBM N series]. These expansion drawers can pack 24 drives in a 4U enclosure. The drives can either be all-SAS, or all-SATA, supporting 300GB, 450GB, 500GB and 1TB size capacity drives.
The [EXP5060 for the IBM DS5000 series] is a high-density expansion drawer that can pack up to 60 drives into a 4U enclosure. A DS5100 or DS5300
can handle up to eight of these expansion drawers, for a total of 480 drives.
Pre-installed with Tivoli Storage Productivity Center Basic Edition. Basic Edition can be upgraded with license keys to support Data, Disk and Standard Edition to extend support and functionality to report and manage XIV, N series, and non-IBM disk systems.
Pre-installed with Tivoli Key Lifecycle Manager (TKLM). This can be used to manage the Full Disk Encryption (FDE) encryption-capable disk drives in the DS8000 and DS5000, as well as LTO and TS1100 series tape drives.
IBM Tivoli Storage FlashCopy Manager v2.1
The [IBM Tivoli Storage FlashCopy Manager V2.1] replaces two products in one. IBM used
to offer IBM Tivoli Storage Manager for Copy Services (TSM for CS) that protected Windows application data, and IBM Tivoli Storage Manager for Advanced Copy Services (TSM for ACS) that protected AIX application data.
The new product has some excellent advantages. FlashCopy Manager offers application-aware backup of LUNs containing SAP, Oracle, DB2, SQL server and Microsoft Exchange data. It can support IBM DS8000, SVC and XIV point-in-time copy functions, as well as the Volume Shadow Copy Services (VSS) interfaces of the IBM DS5000, DS4000 and DS3000 series disk systems. It is priced by the amount of TB you copy, not on the speed or number of CPU processors inside the server.
Don't let the name fool you. IBM FlashCopy Manager does not require that you use Tivoli Storage Manager (TSM) as your backup product. You can run IBM FlashCopy Manager on its own, and it will manage your FlashCopy target versions on disk, and these can be backed up to tape or another disk using any backup product. However, if you are lucky enough to also be using TSM, then there is optional integration that allows TSM to manage the target copies, move them to tape, inventory them in its DB2 database, and provide complete reporting.
Yup, that's a lot to announce in one day. And this was just the disk-related portion of the launch!
It's Tuesday, and you know what that means... IBM Announcements!
IBM System Storage ProtecTIER
Today, IBM refreshed its IBM System Storage ProtecTIER data deduplication family with new hardware and software. On the hardware side, The [TS7650G gateway] now has 32 cores and 64GB RAM. The [TS7650 Appliance] now has 24 cores and 64GB of RAM, and the [TS7610 Appliance Express] has 4 cores and up to 16GB of RAM.
On the software side, all of these now support Symantec's proprietary "OpenStorage" OST API. This applies across the board, from the [Enterprise Edition], [Appliance Edition], and the [Entry Edition]. For those using Symantec NetBackup as their backup software, the OST API can provide advantages over the standard VTL interface.
IBM Systems Director Storage Control
The second announcement has an interesting twist. I could file this in my "I Told You So" folder. Offiically, it's called the [Cassandra Complex], where you accurately predict how something will turn out, but being unable to convince anyone else of what the future holds.
About ten years ago, I was asked to be lead architect of a new product to be called IBM TotalStorage Productivity Center, which was later renamed to IBM Tivoli Storage Productivity Center. This would combine three projects:
Tivoli Storage Resource Manager (TSRM)
Tivoli SAN Manager (TSANM)
Multiple Device Manager (MDM)
The first two were based on Tivoli's internal GUI platform, and the MDM was a plug-in for IBM Systems Director. I argued that administrators would want everything on a single pane of glass, and that we should bring all the components under a common GUI platform, such as IBM Systems Director. Unfortunately, management did not agree with me on that, and preferred instead to leave each interface alone to minimize development effort. The only "unification" was to give them all similar sounding names, four components packaged as single product:
Productivity Center for Data (formerly TSRM)
Productivity Center for Fabric (formerly TSANM)
Productivity Center for Disk (formerly MDM)
Productivity Center for Replication (formerly MDM)
While this management decision certainly allowed version 1 to hit the market sooner, this was not a good "first impression" of the product for many of our clients.
In 2002, IBM acquired Trellisoft, Inc. which replaced the internally-developed TSRM with a much better interface, but again, this was different GUI than the other components. A "launcher" was created that would launch the various disparate interfaces for each component for Version 2. At this point, we have different development teams scattered in five locations, with the first two components being developed by the Tivoli software team, and the other two components being developed by the System Storage hardware team.
Often times, when a technical lead architect and management do not agree, things do not end well. The lead architect has to leave the product, and management is forced to take alternative actions to keep the product going. In my case, management considered the idea of a common GUI as an expensive "nice-to-have" luxury we could not afford, but I considered this a "must-have". I moved on to a new job within IBM, and management, unable to continue without my leadership, gave up and handed the entire project over to the Tivoli Software team.
The Tivoli Software team took a whiff at the pile of code and agreed that it stunk. Dusting off my original design documents, they pretty much discarded most of the code and re-wrote much from scratch, with a common database, common app server, and common GUI platform. Unfortunately, Productivity Center for Replication was held up waiting for some hardware prerequisites, but the other three components would be packaged together as "Productivity Center v3 - Standard Edition" and was a big improvement over the prior versions.
In Version 4, TotalStorage Productivity Center was renamed to Tivoli Storage Productivity Center, and the Replication component was brought into the mix. A scaled-down version packaged as Productivity Center "Basic Edition" was made available as a hardware appliance named "System Storage Productivity Center" or SSPC. The idea was to provide a pre-installed 1U-high hardware console that had the basic functions of Productivity Center, with the option to upgrade to the full Tivoli Storage Productivity Center with just license keys.
So, now, years later, management recognizes that a common GUI platform is more than just a "nice-to-have". IBM now support three very specific use cases:
1. Administration for a single product
For small clients who might have only a single IBM product, IBM is now focused on making the GUI browser-based, specifically to work with the Mozilla Firefox browser, but any similar browser should work as well. The new IBM Storwize V7000 GUI is a good example of this.In this case, the browser serves as the common GUI platform.
2. Administration for both servers and storage devices
For mid-sized companies that have administrators managing both servers and storage, IBM announced this month the new [IBM Systems Director Storage Control v4.2.1] plug-in, which provides Tivoli Storage Productivity Center "Basic Edition" support. This allows admins already familiar with IBM Systems Director for managing their servers to also manage basic storage functions. This is the "I Told You So" moment, connecting server and storage administration under the IBM Systems Director management platform makes a lot of sense, it did when I came up with the idea 10 years ago! Hmmmm?
3. Administration for just the storage environment
For larger companies big enough to have separate server and storage admin teams, IBM continues to offer the full Tivoli Storage Productivity Center product for the storage admins. The most recent release enhanced the support for IBM DS8000, SVC, Storwize V7000 and XIV storage systems.
Today, analysts consider IBM's [Tivoli Storage Productivity Center] one of the leading products in its category. I am glad my original vision has finally come to life, even though it took a while longer than I expected.
