A datacenter is built with a specific maximum power capacity, and power and cooling--not floor or rack space-- is often the limiting factor in determining the compute power in any given facility. Unfortunately, power in the datacenter is rarely efficiently allocated, ***and the full power budget envelope is seldom used***. HP Dynamic Power Capping enables IT to allocate power to individual servers based on actual usage versus faceplate estimates, thereby reclaiming unused energy in the datacenter.
每个数据中心构建时都有一定的最大供电量，决定任何一个数据中心计算能力的限制性因素常常是电力和冷却资源，而不是场地或机架空间。遗憾的是，数据中心中的电力很少得到有效分配，***最大电力余量很少得到使用***。
