据估计,全世界所有的计算机房、数据中心等每年约消耗电能400亿kWh。1从关键基础设备来提高效率任何设备或系统的效率可定义为所需要的有用输出与输入之比。假如机房的用电效率达到100%,那么所有的电能都用到IT设备上。但是,实际上机房需要保持适宜的室内环境、电力供应、冷却以及防护,因此,大部分的电能是机房中的基础电器设备消耗掉的,而不是IT负载。 It is estimated that all computer labs and data centers around the world consume about 40 billion kWh of power annually. 1 Increasing Efficiency from Critical Infrastructure Devices The efficiency of any device or system can be defined as the ratio of useful output to input required. If the electricity efficiency of the engine room reaches 100%, then all the power is used on the IT equipment. However, in fact, the equipment room needs to maintain proper indoor environment, power supply, cooling and protection. Therefore, most of the power is consumed by the basic electrical equipment in the equipment room instead of the IT load.
