IBM's top-end Unix server has moved ahead of its Hewlett-Packard competition in a widely watched server speed test--but HP expects to reclaim its position by the end of March.
By doubling the memory in its 32-processor p690 "Regatta" server from 256GB to 512GB, IBM increased its speed measurement from 403,000 to 428,000 transactions per minute, a smidgen faster than the 423,000 from HP's 64-processor Superdome. HP's system remains less expensive, though, at $6.6 million to IBM's $7.6 million.
The test, run by the Transaction Performance Council (TPC), measures the performance of a server handling simulated database transactions such as checking inventory, placing orders and recording payments. The top-ranked machine still is a 128-processor behemoth from Fujitsu, but it uses unconventional database software. HP and IBM use Oracle 9i.
