Green data centers and hot chips

Today´s computing environment is changing, with growing emphasis on reducing both operational energy costs and the high capital costs to reliably deliver power and cooling to systems in factory-sized data centers. The ldquogreeningrdquo of data centers is challenging microprocessor and system designs, including server, storage, and network designs, to deliver ever higher performance within strict power and cooling constraints. This paper outlines some of the challenges, research approaches and holistic solutions to more energy efficient data centers, starting with microprocessor and system design and extending to the broader environment.
