数据中心的服务器级电源监控可以显着促进其高效管理。然而，由于每个服务器的专用功率计的成本，大多数数据中心电源管理仅关注UPS或集群级电源监控。在本文中，我们提出了一种低成本的新的电源监控方法，只使用一个传感器来提取所有服务器的功耗信息。我们利用服务器电源的传导电磁干扰，通过非侵入式单点电压测量来测量其功耗。使用一对商用级Dell PowerEdge服务器，我们证明我们的方法可以估计每台服务器的功耗，平均绝对百分比误差约为3%。
Server-level power monitoring in data centers can significantly contribute to its efficient management. Nevertheless, due to the cost of a dedicated power meter for each server, most data center power management only focuses on UPS or cluster-level power monitoring. In this paper, we propose a low-cost novel power monitoring approach that uses only one sensor to extract power consumption information of all servers. We utilize the conducted electromagnetic interference of server power supplies to measure its power consumption from non-intrusive single-point voltage measurement. Using a pair of commercial grade Dell PowerEdge servers, we demonstrate that our approach can estimate each server's power consumption with ~3% mean absolute percentage error.
