Abstract :
Direct energy and energy dependent infrastructure costs are major contributors to the total cost of a data center. This paper evaluates the energy saving potential of the ARM Cortex-A9 MPCore processor, compared to more conventional Intel Xeon processors, when running certain server applications. The presented measurements show a three to eleven times better energy efficiency for ARM Cortex-A9 processors compared to Intel Xeon processors. Using these measurements as input to the cost model for a typical data center presented by Hamilton, we analyze the resulting cost reductions.
