Evaluating dynamic performance of VMM in server consolidation

With the IT development, computer is more powerful and can accommodate more virtual servers than ever. Due to users' random requests, it is not economical to start all virtual servers beforehand. One reasonable approach is to start virtual servers dynamically. It will lead to varied performance in server consolidation. Thus, one of the key problems is how to evaluate dynamic performance of VMM in server consolidation. However, no evaluation approach for dynamic performance of VMM in server consolidation is available now. We present an approach to evaluate dynamic performance of VMM in server consolidation. The approach adopts popular application servers, such as Web and database server as workload. We firstly give the problem definition. Then we define performance metrics for evaluating dynamic performance of VMM in server consolidation. Finally, we use the approach to evaluate dynamic performance of VMM in server consolidation.
