数据中心电力需求的超高速增长始于当前和下一代数字专用集成电路（ASIC）-中央处理单元（CPU）、双倍数据速率存储器（DDR）和网络ASIC-所需的高功耗，以及用于人工智能和机器学习功能的高功率图形处理单元（GPU）的爆炸式使用。超大规模数据中心的数量也将从2015年底的259个增加到2020年的485个。到2020年，它们将占所有已安装数据中心服务器的47%[1]。服务器出货量的增长一直受到大型超大规模数据中心的推动，这些数据中心的服务器通常配置为最大限度地提高生产力，并以高利用率运行。服务器功耗不断上升，并且这种趋势将持续到不久的将来，无论是中端还是高端功率服务器[2]，如图1所示。
The hyperspeed growth of data center power demand starts with the high power consumption required by the current and upcoming generations of digital application-specific integrated circuits (ASICs)-central processing unit (CPU), double data rate memories (DDR) and networking ASICs-in addition to the exploding use of high-power graphics processing units (GPUs) for artificial intelligence and machine-learning functions. Hyperscale data centers will also increase in number, from 259 at the end of 2015 to 485 by 2020. They will represent 47% of all installed data center servers by 2020 [1]. Server shipment growth has been driven by large, hyperscale data centers, where servers are often configured for maximum productivity and operate at high utilization rates. Server power consumption is perpetually escalating, and this trend will continue into the near future for both midrange and high-end power servers [2], as shown in Figure 1.
