摘要
数据中心在不断发展,高功率密度的机架也在不断发展,这对电源供给、冷却系统等提出了新的挑战。介绍了《数据中心电信基础设施标准》(ANSI/TIA-942-2005)对数据中心分级及对电源的要求;分析了数据中心的用电负荷,配电系统的可靠性;对各级数据中心配电系统提出了推荐性方案。
Racks with high power density are growing continuously with the growing of data centers, thus resulting in a new challenge to the power supply and cooling system. The classification of data centers and power supply requirements by Telecommunications Infrastructure Standard for Data Centers （ ANSI / TIA - 942- 2005 ） ; the electricity load and the distribution system reliability of data centers are analyzed; the recommended scheme for distribution system of each levels of data centers are presented.
