A storage management apparatus manages a plurality of storage apparatuses in a storage system that disperses and stores data that is made redundant so as to have a predetermined redundancy level. The storage management apparatus includes: a patrol process unit that performs, at a patrol speed, a patrol process of confirming that the plurality of storage apparatuses are being operated normally; a relocating process unit that performs, at a relocating process speed, a relocating process of moving the data between the plurality of storage apparatuses; a recovery process unit that performs, at a recovery process speed, a recovery process of recovering the redundancy level of the data when a fault occurs in the plurality of storage apparatuses; and a processing speed control unit that controls the recovery process speed or a sum of the patrol process speed and the relocating process speed to have a predetermined value. |
