VirtualPower: Coordinated Power Management in Virtualized Enterprise Systems

Tags:
virtualization

Overview Power management has become increasingly necessary in large-scale datacenters to address costs and limitations in cooling or power delivery. This paper explores how to integrate power management mechanisms and policies with the virtualization technologies being actively deployed in these environments. The goals of the proposed VirtualPower approach to online power management are to support the isolated and independent operation assumed by guest Virtual Machines (VMs) running on virtualized platforms and to make it possible to control and globally coordinate the effects of the diverse power management policies applied by these VMs to virtualized resources. To attain these goals, VirtualPower extends to guest VMs 'Soft' versions of the hardware power states for which their policies are designed.
