云数据中心精密空调配电方案浅析

随着云计算大潮的崛起，作为云计算承载体云计算数据中心规模迅速增长。与传统电信级数据中心相比，云计算数据中心具有大规模、高功率密度、高效率、智能化等特点。云计算数据中心与传统电信级数据中心在基础设施等诸多方面存在很大差异。本文讨论了云计算数据中心与传统电信级数据中心基础设施在空调配电方面的不同，分析了现有数据中心常用的几种精密空调配电方案，从可靠性、可维护性、建设内容、建设成本等方面分析了各种方案的优缺点。并结合近年来国内各数据中心因精密空调配电故障造成数据中心故障情况，给出一种适应云计算数据中心的精密空调配电方案。

PrimaryAnalysis on Precision Cooling Power Supply Scheme in Cloud Data Center

The scale ofcloud computing data center which as the basis ofcloud computing is growing rapidly with the rise of cloud computing trend. Compared with telecom data center, cloud computing data center has some characteristics of large- scale, high- density, high- efficiency, intelligence, etc. There are lots of differences in many aspects such as infrastructure between cloud computing data center and traditional telecom data center. This paper studies some kinds of power supply schemes for precision cooling, gets the differences among these schemes, analyzes the advantages and disadvantages of every scheme in terms of reliability, maintainability, building contents, construction costs, etc. Combined with domestic data center failures caused by precision cooling power supply failures in recent years, this paper proposes a power supply scheme of precision cooling applied to cloud computing data center.
