摘要： 分布式存储作为目前流行的数据中心存储系统,在具有高性能、高扩展性的同时,面临着系统能耗增加的问题。为此,基于Ceph分布式存储,分析其数据布局在节能方面的不足,提出划分功耗组的节能优化算法,以提升系统节能比例。建立Ceph的多级功耗模型并给出管理策略,设计并实现Ceph系统的多级功耗管理框架,以进行Ceph系统功耗的动态管理。实验结果证明,该框架能够有效降低Ceph分布式存储的能耗,并保证系统的服务质量和数据可用性。

Abstract: Distributed storage systems are widely used in data centers,because of high performance and scalability,yet most of them are not energyefficient.This paper,based on Ceph,analyses the data layout’s disadvantage in energy saving and proposes a power group partition algorithm to increase the energysaving proportion,builds a multilevel power mode of Ceph and proposes a multilevel power management strategy,besides,it designs and implements a power management framework based on the two former points,to manage Ceph’s power dynamicly.Experimental results show that this framework can reduce the power consumption of Ceph effectively,meanwhile,the quality of service,data availablity are preserved.

Key words: distributed storage, energy saving computing, Ceph storage, power consumption management, data layout
