The supply of power to a storage apparatus can be made redundant by means of power inputs from two types of power supply, namely an AC power supply and a DC power supply. The storage apparatus comprises 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, wherein the power supply unit makes redundant the power supplied from a first power supply device which supplies AC power and/or from a second power supply device which supplies DC power, and supplies this power to the plurality of storage devices, and wherein, in response to an operator configuration input, the power supply controller supplies power from the first power supply device to one storage device among the plurality of storage devices and supplies power from the second power supply device to another storage device.
