Abstract: A migration destination storage apparatus among a plurality of storage apparatuses and has a controller for sending or receiving information to or from a host computer and managing each migration destination volume as an access target of the host computer. The controller manages each migration destination volume by dividing the migration destination volumes into a plurality of resource groups based on identification information for identifying each migration source volume; manages a plurality of resources related to each migration destination volume by associating them with each resource group; and manages each migration destination volume and each resource belonging to each resource group as operation targets to be allocated individually to each migration source user who uses each migration source volume, and as operation targets over which only each migration source user has operation authority.

Abstract: A storage management system, if the required response performance of the file is added to the access request from the host computer, compares the required response performance of the file with the response performance of the pool volume assigned to the page. If the response performance of the compared pool volume does not satisfy the required response performance, the storage management system selects a pool volume whose response performance satisfies the required response performance from the pool volumes, migrates the page to the selected pool volume, and stores the data in the page to which the pool volume is assigned.

Abstract: Resources migrated from migration source storage apparatuses to a migration destination storage apparatus are appropriately allocated to each migration source user. A migration destination storage apparatus among a plurality of storage apparatuses and has a controller for sending or receiving information to or from a host computer and managing each migration destination volume as an access target of the host computer.

Abstract: A computer system regarding which there is no possibility that data loss or data leakage will occur caused by volume migration is provided. The computer system includes: a memory resource to be accessed by a host computer; a storage system for providing a volume, which logicizes the memory resource, to the host computer; and a management device for managing migration of the volume. When detecting a task of migration of the volume based on a request from a first administrator, the management device compares an encryption function setting status of the volume with the encryption function setting status of a migration destination object of the volume; and sends notice of this comparison result to a second administrator, who is different from the first administrator, for security management of the storage system.

Abstract: Problem To constantly allocate the page storing the actual data of the file to which the required response performance is provided in the pool volume satisfying the required response performance. Solution The storage management system 23210, if the required response performance of the file is added to the access request from the host computer 10000, compares the required response performance of the file with the response performance of the pool volume assigned to the page 20041 and, if the response performance of the compared pool volume does not satisfy the required response performance, selects a pool volume whose response performance satisfies the required response performance from the pool volumes, migrates the page 20041 to the selected pool volume 20070, and stores the data in the page 20041 to which the pool volume 20070 is assigned.

Abstract: As a result of operating interference between managing users using the storage apparatus, management tasks on the storage apparatus are delayed and there is the risk of host tasks being delayed or stopped. With a storage apparatus which is managed by a plurality of managing users and a control method thereof, management target resources are divided into a plurality of resource groups; and, by executing exclusive control processing which places the resource groups into an exclusive control range for management operations by the managing users, the scope of the exclusive control can be configured in just proportion and convenience and user friendliness can be improved.

Abstract: The present invention provides a technique capable of preventing data loss due to relocation of physical storage devices. When a request to relocate a logical storage area is issued, it is determined if the logical storage area to be relocated, which is composed of the physical storage devices in the source storage apparatus, can be configured in the destination storage apparatus, and if it is, the physical storage devices that constitute the logical storage area to be relocated are switched into a write-inhibit state in the source storage apparatus, and the write-inhibit state of the physical storage devices is maintained until the physical storage devices are set up and the logical storage area to be relocated is configured in the destination storage apparatus.
