Abstract
A method, computer program product, and computer system are disclosed for disk management in a distributed storage system, wherein the distributed storage system comprises a plurality of disks within a main disk ring, and the disks store target data. In one embodiment, the method comprises dividing the target data into cold target data and hot target data, and grouping one or more disks within the main disk ring into a cold data disk ring and the remaining one or more disks within the main disk ring into a hot data disk ring, based on the cold target data's and the hot target data's positions on disks. The method further comprises migrating the cold target data on disks not within the cold data disk ring onto disks within the cold data disk ring while migrating the hot target data on disks not within the hot data disk ring onto disks within the hot data disk ring, and reducing a spinning rate of disks within the cold data disk ring.
