Abstract: A storage management system, where when adding a specified area of storage media to a storage tiered in response to a request from a host computer, a management computer: obtains storage media information, including I/O frequency of a data storage area of a volume(s) as well as performance information and structure information of the storage media, from the storage apparatus; identifies one or more storage media, which have not been allocated to any of the volumes with the I/O performance in excess of the I/O frequency, on the basis of the structure information of the storage media so that the data storage area of the volume(s), to which a specified storage in the storage tiered is allocated, would achieve a specified I/O performance target; and issues an instruction to the storage apparatus to create a storage tiered by using the identified storage media.

Abstract: A storage tiered that satisfies desired performance is configured by recognizing the type and capacity of storage media of a storage apparatus, which are held by a user, and using the storage media.

Abstract: Even if no port of the attribute communicable with communication ports which the other storage control apparatuses comprise exists among the communication ports which the storage control apparatus comprises, connecting the respective storage control apparatuses as communicable. Among communication ports, the migration source communication port and the migration destination communication port are selected. The path connected to the migration source communication port is migrated to the migration destination communication port, and the migration source communication port is made a free communication port. The attribute of the free communication port is changed to a specified attribute, and the communication port of the other storage control apparatus is connected to the communication port.
