美国数据中心“浪费”宝贵的电力

据称,可将服务器机房的能耗降低40%。

美国自然资源保护委员会(NRDC)数据中心的一个报告称,美国数据中心浪费了价值30亿美元的电力,而通过将服务器机房的电力浪费削减40%,即可节省等量的电力成本。

这个名为《数据中心产业能效缩放:评估核心驱动因素和阻碍因素》称,放置有美国95%服务器的接近300万个数据中心的能效优化进展缓慢,并且不尽平衡。

能效优化在300个数据中心当中的进展缓慢并且不平衡——据估计,这300个数据中心容纳了美国95%的服务器。

这个报告称,因为约有三分之一运行的服务器不再被需要,且更多的服务器“都利用率过低”——仅以18%的容量运行,浪费了几十亿美元和千瓦时的电力。

2013年,美国数据中心的电力能耗达到910亿kWh。

据美国自然资源保护委员会预测,到2020年它们的年度电力能耗将达到1400亿kWh。

这个报告指出,到了那个阶段,美国数据中心产业将需要50个大型的煤电发电站,而这些发电站将排放近1.5亿吨的碳污染物。

该报告虽然认识到缺乏一致的衡量标准,然而却预计2014年数据中心通过提高服务器管理水平可节省390亿kWh的电力。

这个报告指出,这个领域取得进步的最大障碍是内部矛盾。

美国自然资源保护委员会预计,80%的企业机构经历着“激励机制不一致”问题,因为它们的数据中心管理和电力的采购由不同部门负责。

这个报告提出的务实性建议包括协同决策者的激励机制,以及简化衡量服务器使用的标准。

更有争议性的问题是要求公布数据中心能源和碳排放数据,以及为多租赁用户的数据中心设立“绿色租赁”条约。

美国自然资源保护委员会高科技能效总监Pierre Delforge表示,大部分的注意力集中在曝光度高的超大型云数据中心,如谷歌和脸谱网的云数据中心。

“它们的效率已经非常高,且电力能耗仅占到美国数据中心电力能耗的5%,” Delforge说道。

“然而小型、中型的企业和多租赁用户的数据中心仍然在浪费大量的能源。”

Delforge表示,需要创建最佳实践和政策,以加速能效最佳实践在整个产业的采用。

“接近三分之一的租赁出去的数据中心空间将在未来一年进行续约,因此最好是现在就行动,” Delforge说道。

Clicking on one of those will center on that item, and another set of “neighbors” will come into view, allowing you to navigate around exploring by similar artists, songs, or users. Speaking of users, the Zune “Social” is also great fun, letting you find others with shared tastes and becoming friends with them.
