IBM Corp. said it has developed a prototype of a low-power server that cuts power consumption in half when compared to the p610 server that debuted earlier this year with 450W power consumption and dissipation of 1,536 BTUs per hour.
As part of a research effort funded by the Defense Advanced Research Projects Agency to address power consumption and to help reduce cooling and power supply costs for IT infrastructures, IBM said its systems are based on a combination of software tweaks and memory partitioning using either Intel Pentium or IBM PowerPC processor cores.
"The most important issue is to reduce the total cost of ownership and look at how much it takes to run a system," said Mootaz Elnozahy, a manager of the systems software department with IBM Research in Austin. "Doing this involves building cooler processing systems to reduce the overall power in the systems."
IBM established the Low Power Center at the IBM Austin Research Lab as part of a company-wide initiative to address energy consumption. Developments at the lab have included the design and implementation of IBM's 405LP ultra-low power embedded PowerPC processor and the prototype of its Super Dense Server. DARPA also has agreed to provide $2 million in funding to support the Low Power Center.
Separately, IBM is slated to give technical details of its 64-bit PowerPC Microprocessor during the Microprocessor Forum in San Jose in October. According to Micro Design Resources, which organizes the annual event, Peter Sandon, senior processor architect for IBM's PowerPC group will describe a new 64-bit PowerPC processor designed for desktops and entry-level servers.
The processor is based on an 8-way superscalar design that supports symmetric multi-processing and a vector processing unit with over 160 specialized vector instructions, according to MDR.
