数据中心基础设施连续运行要求与能源配置

Continuous Operation Requirements and Energy Configuration of Data Center Infrastructure

现代数据中心对基础设施的一个基本要求是,该系统必须能连续运行,从规划设计的角度讲,连续运行的基本条件是能源输入的连续性。除要求数据中心主供电能源-市电具备较高的可用性外,正确的配置备用能源就成为保障数据中心连续运行的关键。本文从主供电能源一市电掉电后系统的工作状态,以及IT设备对连续供电和连续制冷的要求,讲述了备用能源的配置方法,并对当前业内在备用能源配置方面存在的错误观念和做法,也包括相关标准的适应性和正确性,做了详细的探讨。

A basic requirement of modem data centers for infrastructure is that the system must be able to run continuously. From the perspective of planning and design, the necessary condition for continuous operation is the continuity of energy in put. In addition to the requireme nt of high availability of the main power supply (utility power) for a data center, correct configuration of standby energy is the key to ensure continuous operation of the data center. From the working state of the system after power failure of the main power supply and also the requirement of IT equipment for continuous power supply and continuous refrigeration, this paper describes the configuration method of standby energy. Furthermore, some improper conceptions and practices regarding the standby energy configuration in the current industry are discussed, and the adaptability and correctness of relevant standards are also introduced.
