Abstract
The present invention provides a technique for arranging a virtual logical volume group for satisfying target response performance and realizing a cost reduction. For this purpose, in the present invention, in a storage managing system which manages a storage subsystem comprising in a pool using plural storage devices (hierarchies) having different performances and provides plural virtual logical volumes from the pool, the plural virtual logical volumes are classified into plural groups on the basis of information concerning target response performance concerning each of the plural virtual logical volumes such that each of the plural virtual logical volumes satisfies the target response performance. A new pool is allocated to each of the plural groups of the virtual logical volumes. Further, information indicating a correspondence relation between the pool and the virtual logical volumes included in the groups is generated and the information is output.
