IBM next month will start powering its blade servers with Intel’s low-voltage version of its “Nocona” processor, a move designed to reduce the energy consumption and heat generated by the dense-form-factor systems. Using the processor in IBM’s BladeCenter HS20 systems will reduce the power consumption per processor by about 50 watts and by up to 1.5 kilowatts per chassis. The low-voltage Xeon processor—which, like all chips with the Nocona core, can run both 32- and 64-bit applications—consumes about 55 watts, a little more than half of the 103 watts consumed by the regular Xeon.
