Abstract

Data center management (DCM) is increasingly becoming a significant challenge for enterprises hosting large scale online and cloud services. Machines need to be monitored, and the scale of operations mandates an automated management with high reliability and real-time performance. Existing wired networking solutions for DCM come with high cost. In this paper, we propose a wireless sensor network as a cost-effective networking solution for DCM while satisfying the reliability and latency performance requirements of DCM. We have developed Cap Net, a real-time wireless sensor network for power capping, a time-critical DCM function for power management in a cluster of servers. Cap Net employs an efficient event-driven protocol that triggers data collection only upon the detection of a potential power capping event. We deploy and evaluate Cap Net in a data center. Using server power traces, our experimental results on a cluster of 480 servers inside the data center show that Cap Net can meet the real-time requirements of power capping. Cap Net demonstrates the feasibility and efficacy of wireless sensor networks for time-critical DCM applications.
CapNet:数据中心功率封顶的实时无线管理网络
数据中心管理(DCM)日益成为承载大规模在线和云服务的企业面临的重大挑战。机器需要监控,操作规模要求高可靠性和实时性的自动化管理。现有的DCM有线网络解决方案成本较高。在本文中,我们提出了一种无线传感器网络作为DCM的一种经济有效的网络解决方案,同时满足DCM的可靠性和延迟性能要求。我们开发了Cap Net,一种用于功率封顶的实时无线传感器网络,一种用于服务器集群电源管理的时间关键DCM功能。Cap Net采用高效的事件驱动协议,仅在检测到潜在的功率封顶事件时触发数据收集。我们在一个数据中心部署和评估Cap Net。利用服务器功率跟踪,在数据中心内480台服务器集群上的实验结果表明,Cap Net可以满足功率封顶的实时性要求。Cap Net演示了无线传感器网络在时间关键型DCM应用中的可行性和有效性。
