Data Centers require enormous amounts of electrical energy to operate. The resultant emissions in the form of heat, directly, and carbon, indirectly, are cause for concern among Data Center managers and owners. In the past, and in many contemporary instances as well, Data Center managers have struggled to rein in large energy bills as operational activities increased. This paper attempts to address the problems without affecting operational efficiency of Data Centers and while maintaining high standards of system uptime. The latter is made possible by observing a set standard of Power Usage Efficiency and through rationalizing power consumption of equipment and Data Center infrastructure itself. Our research has shown that it is possible to control power consumption, and thus bring about savings in terms of electric bills paid, even when the count of servers in Data Centers racks increase from four to seven. Experiments conducted in the course of our research indicate to maintain a high quality of Data Center operational state and keep power consumption under control even in the wake of rising user numbers. The resultant savings in electrical units consumed, shall ultimately contribute in a small yet meaningful way towards a smaller carbon footprint and a greener planet.

降低数据中心碳排放的节能方法

数据中心需要大量电能才能运行。由此产生的直接热量和间接碳排放引起了数据中心经理和所有者的关注。过去，在许多当代情况下，随着运营活动的增加，数据中心经理一直在努力控制巨额能源费用。本文试图在不影响数据中心运营效率的情况下解决这些问题，同时保持高标准的系统正常运行时间。后者是通过遵守一套电力使用效率标准并通过合理化设备和数据中心基础设施本身的功耗来实现的。我们的研究表明，可以控制电力消耗，从而节省电费，即使数据中心机架中的服务器数量从四台增加到七台。在我们的研究过程中进行的实验表明，即使在用户数量不断增加的情况下，也要保持数据中心的高质量运行状态并控制功耗。由此产生的电力消耗节省，最终将以一种小而有意义的方式为减少碳足迹和更绿色的地球做出贡献。
