ABSTRACT:
Provided is a computer system which includes plurality of computers including a first, second, and third computers, and a storage device coupled to the plurality of computers via a network, in which: the first computer is configured to: access data in a storage area of the storage device; cut, based on settings information and loads on the plurality of computers, at least a part of electric power supplied to the first computer; and send, before cutting the at least a part of electric power supplied to the first computer, a takeover request to the second computer; and the second computer accesses the data within the storage area after receiving the takeover request. With the configuration as described above, power consumption in NAS is reduced.
