"Armonk, N.Y. and Gainesville, Fla., March 6, 2003 - IBM announced today that the University of Florida has selected the Linux-only IBM eServer zSeries 800 as the heart of the university's Advanced Computing and Information Systems (ACIS) laboratory at the school's Department of Electrical and Computer Engineering in Gainesville, Florida. "The sale of the z800 was made by IBM Business Partner Cornerstone Systems, Inc. The university is the 1,000th customer of IBM's entry-class mainframe, the z800, which began shipping in March of last year. A collaborative grant from the National Science Foundation funded the purchase. "The university plans to integrate the z800 running z/VM, IBM's advanced virtualization software, a 3.36 Terabyte IBM Enterprise Storage Server (code named "Shark") and a 32-node IBM eServer xSeries cluster running VMWare and Linux to support its pioneering research in the emerging field of grid computing. The goal of grid computing is to enable the secure, shared usage of geographically distributed computing resources and services as if they resided on an individual user's computer."
