Abstract
A data storage system includes an interface circuit configured to receive a read request for a chunk of data; a disk array including a plurality of main disks and a plurality of sub disks; an input/output control circuit configured to read a chunk from the main disks according to the read request; a data mapping circuit configured to store mapping relations between logical addresses and physical addresses of chunks; and a data relocation control circuit configured to control relocation of chunks stored in the disk array. The data relocation control circuit is configured to control movement of a first chunk stored in a main disk in an overloaded state to a main disk in an underloaded state, and to control movement of a second chunk stored in a sub disk to a main disk which can accommodate a required bandwidth of the second chunk.
