CSR: Small: Designing Server Clusters to Handle Variable Solar and Wind Power

随着数据中心规模的增加，为服务器集群供电和冷却所消耗的能量已经成为运营数据中心的总拥有成本的重要部分。因此，减少数据中心的能源和碳足迹以及使用诸如太阳能和风能的绿色能源来运行数据中心的趋势越来越明显。在这个项目中，我们将进行基础研究的系统支持服务器集群，旨在使用可变的功率，如可再生能源。我们将设计一种新的供应方技术来管理数据中心服务器集群的能源和电力足迹，并使此足迹适应供应方波动。我们的解决方案使服务器集群中的计算和数据节点能够实现负载循环，从而使其功率和能源足迹能够适应不断变化的供应曲线。我们将设计研究如何分布式存储和服务器虚拟化可以适应利用服务器的这种责任循环，以减少能源使用。这项工作的更广泛的影响包括一个新的研究生研讨会课程可持续计算，夏季REU项目，包括本科生，特别是来自代表性不足的群体，在这项研究中，并推广到K-12教师和社区大学教师通过教程可持续性。

As data centers have increased in size, the energy consumed in powering and cooling server clusters has become a significant fraction of the total cost of ownership of operating a data center. As a result, there is an increasing trend towards reducing the energy and carbon footprint of data centers as well as in using green sources of energy such as solar and wind power to run data centers. In this project, we will conduct fundamental research on system support for server clusters that are designed to run using variable power, such as that from renewable sources. We will design a new supply-side technique to manage the energy and power footprint of a data center server cluster and to adapt this footprint to supply-side fluctuations. Our enables compute and data nodes in a server cluster to be duty-cycled so that their power and energy footprint can be gracefully adapted to a varying supply curve. We will design study how distributed storage and server virtualization can be adapted to exploit such duty-cycling of servers to reduce energy use. The broader impacts of this work include a new graduate seminar course on Sustainable Computing, summer REU projects to include undergraduate students, especially from underrepresented groups, in this research, and outreach to K-12 teachers and community college faculty via tutorials in sustainability.
