摘要
文章首先对数据中心评价指标PUE及其延伸指标DCi E、WUE、p PUE、PUEr、WAPUE的概念及意义进行归纳梳理,进而介绍绿色网格组织(The Green Grid,TGG)新提出的对数据中心进行精确和多维度评价的数据中心绩效指标(Performance Indicator,PI)的内涵和应用。在此基础上,分析归纳影响PUE指标的因素及其应用中存在的争议和问题。综合目前的研究成果,归纳应用指标指导工程实践的合理建议,包括项目自身评价对比、工程扩容扩展的决策评判等方面,以期对相关工程实践提供有益参考。
This paper sums up the concept and signifcance of PUE evaluation indexes and its extension indexes such as DCiE, WUE, pPUE, PUEr, WAPUE used in data centers, then introduces the connotation and application of the new data Center Performance indicators proposed by The Green Grid organization for accurate and multi-dimensional evaluation. On this basis, we summarize the factors that effect PUE index and its application disputes and problems. Based on current researches, reasonable advices for guiding the engineering practice are given, including projects evaluation and comparison, decision evaluation on project scale extension, etc., in order to provide useful reference for relevant engineering practices.
