Abstract: In recent years, the number and size of data centers and cloud storage systems has increased. These two corresponding trends are dramatically increasing energy consumption and disk failure in emerging facilities. This paper describes a new chunk-based proportional-power layout called CPPL to address the issues. Our basic idea is to leverage current proportional-power layouts by using declustering techniques. In this way, we can manage power at a much finer-grained level. CPPL includes a primary disk group and a large number of secondary disks. A primary disk group contains one copy of available datasets and is always active in order to respond to incoming requests. Other copies of data are placed on secondary disks in declusterd way for power-efficiency and parallel recovery at a finer-grained level. Through comprehensive theoretical proofs and experiments, we conclude that CPPL can save more power and achieve a higher recovery speed than current solutions.
