ABSTRACT:
To efficiently manage performance resources while preventing a failure of a control processing from affecting another control processing in a disk array apparatus. The disk array apparatus has a disk array controller, which includes a CPU incorporating a plurality of processor cores that cannot be physically separated from each other, and each processor core serves as an unit processor. One unit processor manages the unit processors separately, allocates a self-contained control program to each unit processor so that the operation of the unit processor can be terminated appropriately or the unit processor can operate until the operation of the whole CPU is terminated, and manages the processing load or processing status of the allocated control program on a unit-processor basis.
