wherein, if a fault occurs with one storage device, among the plurality of storage devices, to which power is supplied from the first power supply device, the power supply controller supplies power from the second power supply device and exchanges the one storage device for another storage device.
12. The storage apparatus according to claim 1,
wherein the power supply unit detects the voltage and current of the power supplied from the first power supply device andor the second power supply device, and
wherein the power supply controller calculates the power consumption amount from the information on the voltage and current detected by the power supply unit and information including the configuration information of the storage device and the power coefficient of the storage device.
13. The storage apparatus according to claim 1,
wherein the first power supply device andor the second power supply device can be installed in the storage apparatus,
wherein the power supply unit identifies the power supplied from the first power supply device andor the second power supply device, and
wherein, at the time of a fault with a power supply which has an identification signal supplied from the first power supply device andor the second power supply device, the power supply unit specifies the type of the faulty power supply, and transmits information including notification to the effect that the power supply of the first power supply device or the second power supply device is to be exchanged to the management terminal connected to the storage apparatus.
14. The storage apparatus according to claim 1,
wherein the power supply unit minimizes the power supplied by the second power supply device, and provides another expansion mechanism for the minimized power to make same compatible with the first power supply device.
15. A power supply method of a storage apparatus comprising a power supply unit for supplying power to a plurality of storage devices and a power supply controller for controlling a method of supplying power from the power supply unit, the power supply method comprising:
a first step in which the power supply unit makes redundant the power supplied from the first power supply device which supplies AC power andor the second power supply device which supplies DC power and supplies this power to the plurality of storage devices; and
a second step in which the power supply controller supplies power from the first power supply device to one storage device among the plurality of storage devices in response to a configuration input by the operator and supplies power from the second power supply device to another storage device.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
