IBM has bolstered the high end of its Unix server line with Power4+ processors and additional features, and disclosed flexible pricing strategies for its pSeries servers.
The eServer p690, p670 and p655 Unix servers now have faster clock speeds as a result of the Power4+ chips, which are available in 1.5GHz and 1.7GHz. The Power4+ chip is a .13 micron version of IBM's Power4 architecture of Unix and Linux servers.
The latest configurations of the p670 and p690 will be available on 30 May, although the latest p655 will not be available until late July.
The p690 starts at $493,386 for an eight-way configuration with the 1.5GHz Power4+ chips, 8Gbytes of memory, two 36Gbyte hard drives and IBM's AIX operating system
The p670 starts at $190,411 for a four-way configuration with 4Gbytes of memory, two 36Gbytes hard drives and AIX.
The p655 will be available in two configurations - a four-way version with the 1.7GHz chip for $50,000 and an eight-way version with the 1.5GHz chip for $70,000.
Customers will be able to buy pSeries servers with additional processors that are turned off until needed. The processor on/off pricing strategy is cost effective for as many as 90 days' of additional processor use, after which it is more economical to buy the extra computing power permanently.
