Patent ID: 7730259

Claim:
A storage subsystem configuration management method for use in a computer system, wherein the computer system comprises a storage subsystem, a host computer connected to the storage subsystem through a network, and a management computer that accesses the storage subsystem and the host computer, wherein the storage subsystem comprises a first interface that is connected to the network, a first processor that is connected to the first interface, a first memory that is connected to the first processor, and a storage device that stores data read and written by the host computer, wherein the host computer comprises a second interface that is connected to the network, a second processor that is connected to the second interface, and a second memory that is connected to the second processor, wherein the management computer comprises a third interface that is connected to the network, a third processor that is connected to the third interface, and a third memory that is connected to the third processor, wherein the storage subsystem comprises a virtual storage resource pool configured by at least one virtual storage extent, and wherein the virtual storage extent is allocated with at least one of a storage resource of the storage device and a storage resource of an external storage device provided by an external storage subsystem connected to the storage subsystem equipped with the storage device, and is provided to the host computer as a storage extent from and into which data is read and written, the storage subsystem configuration management method comprising: obtaining, by the management computer, storage configuration information, which includes at least one of information about a configuration of a RAID (Redundant Array of Independent Disks) group configured by the storage device and information about a configuration of an interface connected to the external storage device, from the storage subsystem through the third interface; obtaining, by the management computer, hardware resource use information, which includes at least one of information about use of the storage resource provided to the host computer through the virtual storage extent and information about use of the interface connected to the external storage device, based on the obtained storage configuration information; determining, by the management computer, based on the obtained hardware resource use information, a configuration of the storage subsystem to prevent from concentrating a load on a specific hardware resource; transmitting, by the management computer, a configuration change instruction to make a change to the determined configuration to the storage subsystem; and making, by the storage subsystem, a configuration change based on the configuration change instruction received from the management computer through the first interface.
