Patent ID: 8589651

Claim:
A migration destination decision support method which is a method for supporting a decision on a storage device as a data migration destination, comprising the steps of: (A) including, each time data is migrated from a migration-source storage device in one or more storage systems comprising multiple storage devices to a migration-destination storage device in the one or more storage systems, information serving as information denoting a migration history related to this data migration and comprising origin identification information which is identification information corresponding to a migration origin being a storage device that is a migration source at the time of a first migration of this data, information related to a migration-source storage device of this data migration, and information related to a migration-destination storage device of this data migration, in history management information which comprises information denoting multiple migration histories; (B) specifying the migration-source storage device; (C) receiving an input of a combination of attribute conditions, which are conditions related to one or more administrator-desired device attributes, for the migration-destination storage device; (D) identifying, based on storage device management information comprising information denoting multiple device attributes for each storage device, all device attribute combinations, which are one or more device attributes that conform to the attribute condition combination that has been inputted in the (C); (E) calculating, based on the history management information and all of the device attribute combinations identified in the (D), migration trends denoting migrations that have been carried out from one or more storage devices that conform to one of the device attribute combinations to one or more storage devices that conform to another one of the device attribute combinations, for multiple migration origins; (F) identifying, from among multiple migration trends calculated for the multiple migration origins, a migration trend to which the specified migration-source storage device belongs, based on the multiple migration trends, the device attribute combination of the specified migration-source storage device, and the migration history related to the migration-source storage device, which is identified from the history management information; and (G) displaying information denoting at least the migration trend identified in the (F) from among the multiple migration trends.
