Server Power Consumption: Measurements and Modeling with MSRs

Piotr Arabas, Michal P. Karpowicz

Abstract: Precise model of power consumption is crucial for the design of controllers improving energy effectiveness of servers. This paper shows how the power usage statistics available via processor registers may be correlated to the total power consumption measurements of servers performing different types of operations. Identification of such relations may support development of power consumption models and application specific energy-aware server controllers.
