快速增长的服务器能源支出和气候变化的警告迫使IT行业关注由可再生能源供电的网络中心。关于这一问题的现有建议产生次优性能，因为它们通常假设某些特定类型的可再生能源，忽视了跨源协调的好处。本文迈出了探索由混合可再生能源系统供电的绿色能源中心的第一步，该系统包括基载电源、间歇电源和备用储能。我们提出了GreenWorks，一个由可再生能源混合供电的绿色高性能计算中心的电源管理框架。具体而言，GreenWorks的特点是针对不同可再生能源的时间和容量量身定制的分层电力协调方案。使用真实的数据中心的工作负载跟踪和可再生能源发电数据，我们表明，我们的计划允许绿色发电商实现更好的设计权衡。
The rapidly growing server energy expenditure and the warning of climate change have forced the IT industry to look at datacenters powered by renewable energy. Existing proposals on this issue yield sub-optimal performance as they typically assume certain specific type of renewable energy sources and overlook the benefits of cross-source coordination. This paper takes the first step toward exploring green datacenters powered by hybrid renewable energy systems that include baseload power supply, intermittent power supply, and backup energy storage. We propose GreenWorks, a power management framework for green high-performance computing datacenters powered by renewable energy mix. Specifically, GreenWorks features a hierarchical power coordination scheme tailored to the timing and capacity of different renewable energy sources. Using real datacenter workload traces and renewable power generation data, we show that our scheme allows green datacenters to achieve better design trade-offs.
