Performance evaluation of server virtualization in data center applications

One of the important targets in new generation data centers is minimizing the cost through efficient use of available resources. Virtualization is a new technology that provides an opportunity for extension of independent virtual resources based on available physical systems. This paper evaluates performance of virtualized versus non-virtualized servers in data center applications. We have presented a tile based evaluation based on heterogeneous workloads to compare several key parameters and demonstrate effectiveness of virtualization techniques. Moreover, we have evaluated the virtualized server models using V-Motion techniques and maximum sever consolidation. Results of evaluation for different criteria confirm that server virtualization technique has high throughput and CPU usage as well as good performance with noticeable agility. Experimental results which are obtained through our prototype model demonstrate that server virtualization can significantly reduces resource consumption while improves system performance. Obtained results certify that server virtualization can be a strategic decision for saving the investment, increasing service performance and creating new virtual environments.
