摘要:
The present invention provides techniques, including a method and system, for relocating data between storage systems. In one embodiment of the present invention a host collects usage information from a plurality of storage systems, and determines the relocation destination LU for data stored in the LU to be relocated. The host alters an LU logical position name table that determines matching between the logical position names of data and LUs. It also carries out data relocation between storage subsystems by shifting data stored in an origin LU to be relocated to a destination LU. In another embodiment relocation of files is provided.
