摘要：
The present invention enables the configuration of a disk array device to be changed in accordance with its purpose of use. Plural disk drive groups each comprising plural disk drives 81 are disposed in the same disk drive unit. Respective disk drive groups are connected to respectively different HDD control boards 82. Each HDD control board 82 is disposed with a connection circuit 200 and switch circuits 210. A signal is outputted from a management terminal to switch the switch circuits 210, whereby adjacent HDD control boards 82 can be connected and operated. Also, by switching the switch circuits 210, adjacent HDD control boards 82 can be mutually separated and operated independently.
