本文描述了两个数据中心效率指标：电源使用效率（PUE）和计算电源效率（CPE）。PUE表征了用于IT工作的总数据中心功率的比例。CPE表征了数据中心的整体效率，考虑了IT设备利用率以及数据中心中的电力使用方式。这里介绍了三项数据中心研究的PUE结果。数据表明，精心设计和管理的数据中心的PUE为2.0。需要更多的研究来确定典型数据中心的价值范围。提出了一个数据中心基础设施和能源成本模型，以比较硬件成本与基础设施和能源成本。通过分析PUE对这些成本的影响，说明数据中心效率对数据中心运营总成本的影响。Copyright © 2007 by ASME
This work describes two data center efficiency metrics: Power Usage Effectiveness (PUE) and Compute Power Efficiency (CPE). PUE characterizes the fraction of the total data center power used for IT work. CPE characterizes the overall data center efficiency, considering IT equipment utilization as well as how power is used in the data center. The PUE results from three data center studies are presented here. The data suggests that a carefully designed and managed data center has a PUE of 2.0. More studies are required to determine the range of values for the typical data center. A data center infrastructure and energy cost model is presented to compare hardware costs to infrastructure and energy costs. The impact of PUE on these costs is examined to illustrate the impact of data center efficiency on the total cost of operating a data center.Copyright © 2007 by ASME
