Abstract: Energy consumption has become an important part of the operational cost of data center,and virtualization technology is one of the effective methods to reduce the energy consumption of data center.In order to reduce the high energy consumption of data center,we used the technology of virtualization,combining the heterogeneity of the physical machine and the multi-dimensional nature of resources that the virtual machine requires in the data center.A measurement model for the performance of different physical machines and another one for the multi-dimensional resource utilization rate were proposed,and then,on the premise of that,a deployment algorithm for virtual machine based on heterogeneous cloud platform was proposed.Simulation results show that the algorithm,compared with the MBFD and BFD,can reduce the energy consumption of system effectively,besides,it improves the utilization rate of resources and reduces the waste of resource.

Key words: Virtualization,Data center,Heterogeneous,Energy consumption
