摘要： 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.

摘要： 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.

摘要： 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.

摘要： Provided is a storage device which partitions data from a host into multiple partitioned data and distributes, encrypts and stores them together with a parity to and in multiple memory mediums. This storage device executes processing of restoring the partitioned data or the parity stored in a memory medium to be subject to encryption re-key based on decrypted data of the partitioned data or the parity stored in each memory medium other than the memory medium to be subject to encryption re-key among the multiple memory mediums, storing the restored partitioned data or the parity in a backup memory medium while encrypting the restored partitioned data or the parity with a new encryption key, and thereafter interchanging the backup memory medium and the memory medium to be subject to encryption re-key so that the backup memory medium will be a memory medium configuring the parity group and the memory medium to be subject to encryption re-key will be the backup memory medium.

摘要： In order to manage and operate Pool created in storage system A and a virtual volume using Pool in storage system B, it is required to copy the virtual volume of storage system A into a virtual volume of storage system B and new storage regions for copy of virtual volume into storage system B are needed. Storage system B acquires configuration information of Pool and a virtual volume of storage system A and inputs a logical volume included in Pool of storage system A to storage system B based on the acquired configuration information. Storage system B transforms the acquired configuration information for use in storage system B and creates Pool and a virtual volume from the input logical volume based on the transformed configuration information.
