数据中心电源管理正从基于最大节点功率使用的自组织方法发展到采用功率可伸缩组件的系统方法。此外，还可以利用功率和吞吐量的关系来增加执行的总工作量，并安全地超额提供机架空间，同时保持低于总功率限制。这项研究描述了一个一般的框架，提高吞吐量在一个地方一级，同时负载平衡的可用聚合功率下的一组操作约束。我们的解决方案适用于那些由于计划外电源波动而无法扩展电源电路数量或寻求有效利用其可用电源预算的数据中心。该框架特别适合于具有异构工作负载的环境，因此具有非均匀的功率分配要求。基于两分钟内的典型工作负载，本文表明非均匀功率分配方案比均匀功率分配机制提高了16%以上的吞吐量
Data center power management is evolving from ad hoc methods based on maximum node power usage to systematic methods that employ power-scalable components. In addition, it is possible to exploit the power and throughput relationship to increase the total work performed and safely overprovision the rack space while staying below an aggregate power limit. This research describes a general framework for boosting throughput at a local level while load-balancing the available aggregate power under a set of operating constraints. Our solution is useful for those data centers that cannot expand the number of power circuits or seek effective usage of their available power budget due to unplanned power fluctuations. The framework is particularly well suited for environments with a heterogeneous workload and hence, a non-uniform power allocation requirement. Based on a representative workload for a two minute period, this paper shows a non-uniform power allocation scheme increases throughput by over 16% versus a uniform power allocation mechanism
