摘要： 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. 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.

摘要： In a storage system 1, a storage apparatus A having a first pool 1430 including segments as unit storage areas and a storage apparatus B having a second pool 1430 having the same configuration are communicably connected to each other. In the storage system, an external volume identifier is associated with a logical volume 1420 included in the first pool 1430, the external volume identifier being used by a controller 1500 in the storage apparatus B to identify and manage the logical volume 1420 as an external volume 1425 that is a virtual volume in the storage apparatus B. Moreover, a volume identifier 5110 of the logical volume 1420 included in the first pool 1430 is rewritten into the external volume identifier in order to enable the storage apparatus B to utilize the logical volume 1420 created from the first pool 1430.
