Optimized Management of Power and Performance for Virtualized Heterogeneous Server Clusters

This paper proposes and evaluates an approach for power and performance management in virtualized server clusters. The major goal of the authors approach is to reduce power consumption in the cluster while meeting performance requirements. The contributions of this paper are: a simple but effective way of modeling power consumption and capacity of servers even under heterogeneous and changing workloads, and an optimization strategy based on a mixed integer programming model for achieving improvements on power-efficiency while providing performance guarantees in the virtualized cluster.
