Abstract
Each of one or more storage device units has a switch device for relaying communication in accordance with a communication interface in which the number of master devices that can exist in the same domain is defined and having a plurality of switch ports. A controller unit has a storage controller having a plurality of initiator ports. A storage controller acquires, via each of the plurality of initiator ports, the ID of a storage device unit connected to the initiator port. The storage controller determines a system configuration on the basis of a port ID relationship between the plurality of initiator ports and the plurality of acquired IDs. The storage controller performs switch setting, for each of the one or more switch devices, that corresponds to the determined system configuration, via at least one initiator port connected to the switch device.
