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.
