Method for scaling the speed of operation of at least one processor unit in a virtualized resource-sharing system

摘要

The invention refers to a method for scaling the speed of operation of at least one processor unit in a virtualized resource-sharing system in order to reduce power consumption, wherein the virtualized system comprises at least one server and a total number of N virtual machines (VMs) running on N·a switched-on processor units, by adjusting the speed of at least one processor unit (and preferably of all processor units) to its maximum speed multiplied by a factor that depends on the number of active VMs. Estimations of performance and power consumption are also part of the invention.
