The Case for Energy-Proportional Computing
December 2007 (vol. 40 no. 12)
pp. 33-37
Energy-proportional designs would enable large energy savings in servers, potentially doubling their efficiency in real-life use. Achieving energy-proportionality will require significant improvements in the energy usage profile of every system component, particularly the memory and disk subsystems.
