Abstract
Rush current is dispersed with a power control section having a simple construction, irrespective of the number of disk units. A plurality of disk modules each having a built-in power section and a built-in disk drive are grouped and housed in a single disk unit. A plurality of disk units are provided in response to the system scale. An input/output control section is provided in a disk unit, and performs control of data input/output to and from the plurality of disk modules in the same unit and issuance, upon power-on, of a power-on instruction in compliance with a predetermined procedure. There is provided a first power control section common to all the disk units for instructing power-on in a lump. A second power control section is provided for each disk module of a disk unit, and instructs power-on to the power section and the disk drive within the module upon receipt of both a power-on instructing signal from the input/output control section in the same unit and another power-on instructing signal from the external first power control section.
