摘要： This invention provides a storage system enabling it to properly rebuild a storage device involved in failure. In the storage system, a controller repairs data for which an access request has been issued, returns a reply to the source of the access request, and stores the repaired data. As regards data for which access is not requested, the controller executes rebuilding of storage regions corresponding to rebuild management units in priority-based order and changes priority for executing the rebuilding, based on access frequencies for a first period and access frequencies for a second period that is shorter than the first period.

摘要： Even though storage systems are different in types, storage pools in a plurality of storage systems are integrated, and a storage volume is created in a suited storage pool corresponding to a storage requirements. In an information system where a plurality of storage systems (a disk array, an SDS system, and an HCI system) is present, when creating the storage volume using requested storage requirements as parameters, a storage management server selects a storage pool that satisfies the storage requirements based on comparison of the storage requirements and characteristic information held in first management information (a storage pool management table), the server creates the storage volume in the selected storage pool, and the server adds an entry relating to the created storage volume to second management information (a volume management table).

摘要： The present invention effectively utilizes computation resources by allocating the computation resources, in accordance with conditions, to a process that shares a computation resource with another process and a process that occupies a computation resource. Execution control causes a processor core allocated to a storage control process to be occupied by the storage control process, the execution control causes a processor core allocated to an application process to be shared with another process, and the execution control changes the number of processor cores allocated to the storage control process on the basis of I/O information indicating a state of an I/O.

摘要： A file server stores storage management information and migration policy information. The storage management information includes information that indicates a storage attribute for each storage apparatus. The migration policy information includes a plurality of information sets. Each of the information sets includes information that indicates a condition of a file attribute and information that indicates a condition of a storage attribute of a storage apparatus that is a migration destination. The file server specifies a migration target file, specifies a storage apparatus that conforms to the storage attribute condition indicated by the information set that includes the information indicating a condition of a file attribute that conforms to that of a file attribute of a target file based on the storage management information, and migrates a target file from a storage apparatus that has stored the target file to the storage apparatus that has been specified.

摘要： A scale-out storage system includes a plurality of computer nodes each of which has a memory and a processor, and a storage apparatus. The computer nodes have one or more redundancy groups each of which is a group for metadata protection. Each of the one or more redundancy groups includes two or more of the computer nodes including a primary node being a primary computer node and a secondary node being a secondary computer node, and a failover is performed from the primary node to the secondary node. The memory of the primary node has stored therein metadata related to the redundancy group and to be accessed for control. The metadata is redundantly stored in the memory of the primary node and the memory of the secondary node.
