摘要

在过去的几十年里，对计算机基础设施和软件不断增长的需求导致了数据中心的数量和规模的显著增加。数据中心使用的能源(这里包括IT设备的电力和冷却基础设施的电力)急剧增加。电能使用效率(PUE)是衡量数据中心(DC)能源效率的经典指标。讨论了它的优点和缺点。综合了改进PUE的一些补充指标和新指标。这一分析有助于研究人员识别直流系统能效评估的主要趋势。

An analysis of the power usage effectiveness metric in data centers

During the last decades the growing demand for computer infrastructures and software has led to important increased in the number and the dimension of data centers. The energy used by the data centers (here are included the power for IT equipment and the power for the cooling infrastructure) has increased dramatically. The paper proposes an analysis of Power Usage Effectiveness (PUE), the classical metric for measuring energy efficiency in Data Centers (DC). A discussion of its advantages and of its shortcomings is presented. Some complementary metrics and new metrics for improving PUE are synthesized. This analysis can help researchers to identify the main trends of Energy Efficiency assessment in DC.
