Abstract:
1. A management method for a storage system including a storage subsystem configured to store data, a host computer configured to communicate data with the storage subsystem, and a system management device configured to provide management functions to the storage system, the storage subsystem including a plurality of components, the method comprising: displaying a configuration window on a display area of the system management device, the configuration window providing a view of a configuration of the plurality of components in the storage subsystem and load information for each of the plurality of components, and allowing a user to enter proposed adjustments to configuration information for at least one of a logical or physical configuration of said storage system and an operational status; displaying a performance window on the display area of the system management device together with the configuration window, the performance window providing bandwidth utilization information relating to at least one of the plurality of components in the storage subsystem, the performance window allowing the user to enter proposed adjustments in performance through a setting of various performance parameters; displaying at least one of a real-time mode graph and a performance history mode graph of the at least one component whose bandwidth utilization information is being displayed on the performance window, the displayed graph being dependent upon a selection of the user, the real-time mode dynamically providing the bandwidth utilization information and the performance history mode providing the bandwidth utilization information for a given period in the past, the configuration window, the performance window, and the graph being displayed together on the same display area to be viewed by a user at the same time; simulating performance of at least one of the plurality of components in the storage subsystem based on the proposed adjustments to the configuration parameters and performance parameters, whereby the user is able to compare simulated performance using the proposed adjustments to past performance as displayed in the graph, such that the user is able to alter the proposed adjustments and view the simulated results in real-time before applying the proposed adjustments to the storage subsystem; displaying a setting window on the display area of the system management device, said setting window including a configuration change screen comprising a configuration area for displaying configuration information for storage volumes among the plurality of components, a list area for displaying a correspondence relationship that the user is able to indicate between a source volume and a target volume for data migration, and a graph area for displaying a performance graph able to show performance of at least one of a prior and a present source and target volume and a simulating graph able to show a simulated performance of at least one of the prior and the present source and target volume based on applying the correspondence relationship; and indicating a candidate target volume that is able to migrate the data stored in the selected source volume and a non-candidate target volume with a different identifier.
