PROBLEM TO BE SOLVED: To provide a system for correctly recognizing a SAN topology since conventional SAN management cannot recognize geographical distance between devices. SOLUTION: The system comprises a topology repository, a SAN manager, and a discovery list. The topology repository stores configuration data of a SAN. The SAN manager, coupled to the repository and the discovery list, receives configuration data in response to a request for configuration data from each component in the SAN in accordance with the discovery list; compares received data with data stored in the repository; updates the repository with the received data if the received data differs from the stored data; and outputs data stored in the repository, the output data showing distance between a switch and components coupled to the switch.
