摘要
数据中心数量及规模的增长使得数据中心能耗问题愈发凸显,多国政府针对数据中心能耗问题制定了相应的政策、法规,以促进数据中心节能。对数据中心能耗构成及能效指标进行了研究,从供配电系统、制冷系统及IT设备3个方面对数据中心能效影响因素进行了分析,然后对当前主流的数据中心能效优化策略进行了总结;在此基础上,提出了数据中心即服务的能效优化策略,该能效优化策略充分考察了数据中心服务性能和能耗的匹配性,能够有效实现数据中心全局能效优化。
The growth of the number and scale of data centers makes the energy consumption problem of data centers more and more prominent.Many governments have formulated corresponding policies and regulations to promote the energy saving of data centers.The energy consumption of data center is mainly composed of power supply and distribution system energy consumption,refrigeration system energy consumption and it equipment energy consumption.This paper first analyzes the energy consumption composition and energy efficiency index of data center,then analyzes the influencing factors of energy efficiency of data center from three aspects of power supply and distribution system,refrigeration system and it equipment,summarizes the current mainstream energy efficiency optimization strategies of data center,and on this basis,puts forward the data center as a This energy efficiency optimization strategy fully investigates the matching of data center service performance and energy consumption,and can effectively realize the global energy efficiency optimization of data center.
