Power and Performance Modeling in a Virtualized Server System

Abstract

Virtualization has become a very important technology which has been adopted in many enterprise computing systems and data centers. Virtualization makes resource management and maintenance easier, and can decrease energy consumption through resource consolidation. To develop and employ sophisticated resource management, accurate power and performance models of the hardware resources in a virtualized environment are needed. Based on extensive experiments and measurements, this paper presents accurate power and performance models for a high performance multi-core server system with virtualization.
