IBM has unveiled eleven new servers that meet stringent version 2.0 guidelines now in effect under the U.S. Environmental Protection Agency's ENERGY STAR(R) program. A virtual explosion of data, estimated at 2.5 quintillion bytes a day and growing, is driving up energy costs in data centers. Qualifying criteria for the new ENERGY STAR rating -- including features such as efficient power supplies, real time power usage measurement, advanced power management for lowering usage during idle periods -- can help organizations dramatically lower the amount of energy required to run data centers increasingly under pressure to handle more data more efficiently.

IBM's servers that have earned the ENERGY STAR cover the full range of IBM's two and four socket systems: four from IBM's Power Systems line-up; and seven from the IBM System x and Pure Flex series. All ENERGY STAR version 1.0 qualified servers are now expected to meet the version 2.0 requirements and provide data on the server's performance/power characteristics. The specific Power System and System x servers qualified for ENERGY STAR version 2.0 include: Power 730, Power 740, Power 750 and Power 760 servers.

The qualified System x servers are: x3650 M4 HD, x3650 M4, x3500 M4, x3550 M4, dx360 M4, nx360 M4 and x222.
