Abstract:
A power device of the present invention makes a plurality of DC/DC converters redundant, and supplies power individually to a plurality of disk drives. Each first DC/DC converter is respectively made correspondent to a subgroup. One first DC/DC converter is connected to the disk drives respectively inside one subgroup, and the other first DC/DC converter is connected to the disk drives inside the other subgroup. A second DC/DC converter is made correspondent to all of the subgroups. Second DC/DC converters respectively supply direct-current power to any one disk drive of the disk drives in the subgroups.
