<p>Provided is a computer system including a host computer (106), a storage system (131), and a management computer (110), in which the storage system receives data I/O request to virtual logical volumes and data I/O request to one or more real logical volumes (137), each of the virtual logical volumes is allocated to one of one or more pools (138), storage areas of physical storage systems are allocated to all storage areas defined as the pools, and when a performance problem has occurred in one of the virtual logical volumes, the management computer selects the one of the virtual logical volumes, and selects a pool other than the pool to which the selected virtual logical volume is allocated and the real logical volumes as a migration destination of the selected virtual logical volume, to thereby prevent a performance problem from being caused by interference among the virtual logical volumes sharing the pool.</p> |
