Method and apparatus for controlling power supply to recording devices of redundant-array-of-independent-disks group

An apparatus for controlling power supply to recording devices of a redundant-array-of-independent-disks group, the apparatus comprising:

• a power supply unit that supplies power for each of a plurality of power supply groups configured to supply the power to a first recording device that belongs to a first redundant-array-of-independent-disks group and a second recording device that belongs to a second redundant-array-of-independent-disks group, the second redundant-array-of-independent-disks group including recording devices different from those of the first redundant-array-of-independent-disks group;
• and
• a power-supply control unit that cuts off, when a malfunction occurs in a specific recording device, power supply to a power supply group that includes the specific recording device, wherein
• each of the power supply groups includes
• at least one recording device that belongs to the first redundant-array-of-independent-disks group;
• and
• at least one recording device that belongs to the second redundant-array-of-independent-disks group.
