Metrics for Computing Performance of Data Center for Instigating Energy Efficient Data Centers

Data centers now play an important role in modern IT infrastructures. Although much research effort has been made in the field of green data center computing, performance metrics for green data centers have been left ignored. This paper is devoted to identify and implement energy efficiency and green computing performance metrics in data centers. The metrics h elps data center managers to measure and implement cost and power savings in data centers. A metrics based energy efficiency model for categorizing data center into measureable units is proposed which divides data center into four measureable areas and maps metrics to measure their efficiency and performance. The results generated after applying Power Usage Effectiveness metrics clearly demonstrate poor performance of data center with PUE value of 3.5, which indicates very inefficient data center.
