An active control program and a passive control program included in the same program cluster in a plurality of storage nodes are each arranged in the storage nodes different from each other. Each of the storage nodes is configured to include a plurality of active or passive control programs. When any one of the plurality of the passive control programs is switched to active, a change of an operation status is made for the different passive control program operating in the storage node that includes the passive control program switched to active.
