Abstract:With the rapid development of computer hardware performance and virtualization technology, server virtualization technology is being used increasingly to reduce the integration cost of information center room or improve hardware utilization. However, how to choose the best server hardware to build high performance and low cost virtualization platform, especially on performance evaluation is one of the urgent problems. This paper briefly introduces four kinds evaluation methods of virtual server. Through the analysis and comparison between different methods, it assess the advantages or disadvantages of evaluation methods and its application environment. Based on the analysis above, it puts forward reference suggestions for better deploying server virtualization system.
