ABSTRACT:
A disk array subsystem includes a logical volume allocation controller, which divides and reallocates data of the same logical volume LVN among a plurality of magnetic disk drive groups when a magnetic disk group is added thereto. Successful logical-volume allocation can reduce the I/O processing frequency between magnetic disk drive groups, thus achieving enhanced performance of the disk array subsystem.
