Abstract: A method for storage management is provided which displays the materials on which it is determined which of the thin provisioning volume or the logical unit (LU) is to be used for storage promotion. The method is executed in a computer system having one or more host computers, one or more storage subsystems, and a management computer. The storage subsystem includes a physical disk and a disk controller. The disk controller provides the host computer with the thin provisioning volume. The management computer obtains the allocated capacity from the disk controller and the host-recognized capacity from the host computer. By subtracting the obtained allocated capacity from the host-recognized capacity, the management computer calculates an improved capacity. By dividing the calculated improved capacity by the obtained host-recognized capacity, the management computer calculates an improvement ratio and displays the calculated improvement ratio.

Abstract: A user operates an input device to set information necessary for reserving a volume and a port while looking at a screen for reservation management displayed on a display device Next, a storage management program retrieves reservable volumes and ports using a volume retrieval subprogram of a policy basis. At this point, when a policy concerning performance is inputted, the storage management program inquires of a performance analysis program of a storage performance management server whether the performance is satisfied. When the volume and the port are found, the storage management program stores reservation information in a reservation management DB using a reservation subprogram. When the volume and the port are not found, the storage management program judges whether an alternative volume for the reserved volume is present using a volume adjustment subprogram.
