ABSTRACT:
The disk array device supplies appropriate power to various parts in accordance with the operating mode in cases where the output of the main power supply drops. The disk array device adjusts the power from a commercial power source6with an AC/DC power supply5, and supplies this power to a power supply common bus7. A disk drive group1and a control circuit board group2constituting electrical loads are respectively connected to the power supply common bus7. When the supply of power from the main power supply stops, the capacitor box3supplies a relatively large current for a short time only, in order to retain data during an instantaneous power outage. Then, the battery boxes4supply power to the power supply common bus7for a relatively long period of time, in order to perform destage control and memory backup. The battery boxes4perform balancing control of the output current in order to suppress variation in the output current value among the battery boxes4.
