Abstract:
This storage control apparatus 100 is able sufficiently to manifest the merits of economization of electrical power. The storage control apparatus 100 includes one or more additional storage units 150 which are adapted for the supply of power to them to be turned ON and OFF individually. Each of these additional storage units 150 includes a plurality of storage devices 154 (for example, a plurality of HDDs). When a user actuates a management device 106, and causes one or more RAID groups and a spare HDD for each of these RAID groups to be set within the storage control apparatus 100, an MPU 140 of the storage control apparatus 100 controls the management device 106 to make the user set each RAID group and the spare HDD for it within the same additional storage unit 150.
