PUE与WUE双优型数据中心构建方法
Construction method for PUE and WUE dual-optimal data center
摘要:
随着云计算、数据中心行业的快速发展,其能源消耗与水资源消耗增加的问题日益凸显,为建设PUE(电能利用效率)与WUE(水利用效率)双优型绿色数据中心,本文介绍了几种可行的冷却系统解决方案,并进行了技术经济分析,着重对比了系统原理、运行模式、算力产出、PUE、WUE、CLF(冷却负荷因子)、TCO(总体拥有成本),提出了PUE与WUE双优型数据中心的构建方法,并就不同设计目标的数据中心给出了方案建议。
Abstract:
With the rapid development of the cloud computing and data center industries, the issues of energy consumption and water consumption are becoming increasingly prominent. To build a green data center with power usage effectiveness (PUE) and water usage effectiveness (WUE) dual-optimal, this paper presents several feasible cooling system solutions and conducts a technical and economic analysis. It focuses on comparing system principles, operation modes, computing power output, PUE, WUE, cooling load factor (CLF), and total cost of ownership (TCO). It proposes a construction method for a PUE and WUE dual-optimal data center, and provides scheme suggestions for data centers with different design goals.
