Abstract: The present invention can shorten a response time required by a client computer to receive configuration information after transmitting a request for the configuration information to a storage system. A storage controller updates a plurality of pieces of configuration information based on control. A server computer transmits, to a storage controller, input information designating configuration information among the plurality of pieces of configuration information, according to a preconfigured schedule. The storage controller transmits output information including the configuration information inside the storage controller to a server computer based on the input information. The server computer receives output information, and stores the output information in association with the input information. Upon receipt of the input information from a client computer, the server computer transmits the output information associated with the received input information to the client computer.
