The latest servers are part of Compaq's price performance strategy, which is aimed at attacking similar technology from rival IBM, said Paul Miller, director of marketing for Compaq's industry standard server group.
The ProLiant DL580 offers hot-swappable, mirrored memory which provides for internal failover. Powered by Intel's Xeon MP processor, the ProLiant DL580 is available in configurations of as many as four Xeon chips. It starts for $8,499 (£5,812), according to Compaq.
The company also released a two-way ProLiant ML530 and issued upgrades to two other Intel-based systems.
The ProLiant ML530 runs Intel's Xeon dual processor (DP) chips. Sporting PCI-X bus technology for faster I/O throughput, the ML530 runs for $5,199 (£3,555).
Compaq added ATA RAID capabilities to two existing servers, the ProLiant ML350 and ProLiant ML330. The ML350 and ML330 start at $1,949 (£1,333) and $1,422 (£972), respectively.
Compaq is second only to IBM in a recent report on worldwide server market share by IDC. Compaq holds a 16.3% share of the overall worldwide server market, behind IBM's 26.3% share of the same.
