数据中心服务器功耗模型研究进展

Research progress of server power consumption model in data center

数据中心为中国经济社会的蓬勃发展提供了强大的支撑力量,同时数据中心的高速发展也带来了巨大的能耗问题。数据中心服务器是能流和热流的基本单元,本文探讨了服务器的分类、不同工作负载下的机架功耗趋势;从3个方面梳理国内外研究中所使用的服务器功耗模型,并对模型的准确性以及模型应用进行了研究,以期为数据中心发展提供借鉴。

Data centers have provided a strong supporting force for the vigorous development of China's economy and society;at the same time,the high-speed development of data centers has brought about huge energy consumption problems.As the basic unit of energy and heat flow in data center servers,in this context,this paper discusses the classification of servers,the trend of rack power consumption under different workloads;compares the server power consumption models used in domestic and international studies from three aspects and investigates the accuracy of the models as well as the application of the models,in order to provide reference for data center development.
