The new IBM servers will be shipped with the company's new Tivoli Usage and Accounting Manager metering tool, IBM said. The tool can track usage by business unit, helping companies better allocate costs, said Jeff Howard, director of System P marketing at IBM.

The servers will be available Aug. 11. Pricing was not immediately disclosed by IBM.

Separately, the Power.org group, founded by IBM and 11 other firms in 2004 to develop and promote the Power technology, last week disclosed that it has developed a unified Instruction Set Architecture (ISA) for the Power processor.

The ISA details how a chip communicates with the operating system.

Previously, the Power ISA was slightly modified for different uses, such as for desktops, embedded systems and servers.
