Title: Cluster system and method of controlling power-supply to blade servers included in cluster system

Abstract: A cluster system includes a plurality of blade servers including at least one auxiliary blade server, the rest of the blade servers being used for actual operation of the cluster system, a power-supply unit supplying electrical power to each of the blade servers, a power-supply controller which controls on/off in supplying electrical power to each of the blade servers from the power-supply unit, and a blade server monitoring unit which monitors whether there occurs any trouble in each of the blade servers. The power-supply controller, when the blade server monitoring unit finds a trouble in any one of the blade servers, stops power-supply to a blade server in which the trouble was found, and turns the auxiliary blade server into a blade server to be used for actual operation of the cluster system, in place of the blade server in which the blade server monitoring unit found a trouble.
