ABSTRACT:
The present invention includes a plurality of disk units for storing data from a host computer, a plurality of power supply apparatuses for supplying DC power to each of the disk units via main power supply wirings, and a redundant power supply apparatus for generating, with any one of the disk units among the plurality of disk units as a load, DC power to the load. As auxiliary power supply wirings for guiding the output of the redundant power supply apparatus to each of the disk units, a common power supply wiring that is common to each of the power supply apparatuses, a plurality of branch power supply wirings branching from the common power supply wiring and connected to each of the disk units, and a redundant power supply wiring for connecting the redundant power supply apparatus and the common power supply wiring are wired to a backboard.
