The storage control device of the present invention reduces the power consumption amount by stopping the transmission of power to enclosures that are not accessed. A plurality of additional enclosures are switch-connected via backend switches to a base enclosure. Drives that have not been accessed for a predetermined time or more undergo spin-down. When all of the drives in the enclosure enter a spin-down state, the supply of power from the power supply in the enclosure to the respective drives is stopped. The base enclosure that manages the system constitution of the storage control device turns OFF the switch connected to the enclosure when all of the drives in a certain enclosure have spun down. The transmission of power to this enclosure is accordingly stopped.
