摘要：Moderncloud data centers are virtualized for resource multiplexingand services consolidations. Virtual machines (VMs)residing in the same server cluster share the same hardware resources and power supply while they may have different QoS requirements for their services and applications. Moreover, the power consumption of the server cluster ishighly dynamic since different virtual machines have different workloads due to different services requests.Cluster level power and QoS coordination is crucial for data center level energy efficiency coordinationas well as high quality service provisioning.In this paper we propose the power and QoS aware multi-level resource coordination and schedulingin virtualized servers, i.e., the cluster-level power control layer, the VMs resource allocationlayer, and the QoS optimizationlayer. Thisthree-levelcontrollingframeworkschedulesand allocateshardware resource for QoS guaranteeandcluster levelpowermanagement.We use dynamic frequency scaling for QoS mitigating when power budgetchanges. The experimentresults show that the proposed multi-level coordinatedcontrol architectureconsumes 5.36%and6.96%less power for web servers and computing intensive virtual machines, respectivelywhile itcan guarantee the response time of web server and execution time of computing tasksno more than those without the proposed controlling approach.
