A year ago today, July 1 2008, the new PeopleSoft Enterprise Financials System ("EFS") went live. As of that moment, the old CUFS system running on the Mainframe went into "legacy" mode, running reports. All new financial data went into EFS.
Today, July 1 2009, the Mainframe has officially been decommissioned. This was the last step in a year-long system retirement plan. It's an end of an era.
I'd like to take a moment to recognize those of you who assisted with the Mainframe, either during its production run, or in the recent shutdown. The University has relied on the Mainframe as our primary enterprise computing system for more than 30 years. The Mainframe is a solid platform, designed to handle very high volume input and output (I/O) and emphasize throughput computing. The Mainframe was the first to offer virtual machines, each with its own protected address spaces. Our IBM zSeries Mainframe ran up to 4 "logical partitions", although I believe by the time EFS went live we only had 3 LPARs.
Yet, times change. In the last 10-15 years, the IT industry has increasingly replaced Mainframe platforms with "open systems" (UNIX, Windows, ..) and personal computer networks. But we shouldn't forget the roots of this industry workhorse.
