To efficiently manage performance resources while preventing a failure of a control processing from affecting another control processing in a disk array apparatus. A disk array apparatus (1) has a disk array controller (11), the disk array controller (11) has a CPU (110) incorporating a plurality of processor cores (1110-111N) that cannot be physically separated from each other, 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 in such a manner that the operation of the unit processor can be terminated appropriately or in such a manner that 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. |
