Abstract
A power supply unit 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 includes recording devices different from those of the first redundant-array-of-independent-disks group. A power-supply control unit cuts off, when a malfunctioning occurs in a specific recording device, power supply to a power supply group that includes the specific recording device.
Claims6
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 malfunctioning occurs in a specific recording device, power supply to a power supply group that includes the specific recording device.
A method of controlling power supply to recording devices of a redundant-array-of-independent-disks group, the method comprising:
- supplying 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
- cutting off, when a malfunctioning occurs in a specific recording device, power supply to a power supply group that includes the specific recording device.
