A storage apparatus includes a plurality of resources including a plurality of types of surplus resources, determines a surplus resource introduction plan used for coping with abnormalities, and controls allocation of the surplus resources according to the determined introduction plan. The storage apparatus includes a processor. The processor detects an abnormality associated with the resource of the storage apparatus, calculates one or more surplus resource introduction plans capable of coping with the abnormality on the basis of management information of the resource of the storage apparatus when the abnormality is detected, and determines, when there are a plurality of introduction plans, an introduction plan used for coping with the abnormality on the basis of a state in which other abnormalities that are likely to occur concurrently with the abnormality can be coped with, by surplus resources remaining when the introduction plans are executed.

Resource management apparatus, resource management method, and nonvolatile recording medium

A storage control apparatus includes a first logical volume in which data has been stored in a pool that includes at least one of one or a plurality of logical volumes based on a plurality of physical storage devices as a pool volume, and divides the first logical volume into at least two real areas. The storage control apparatus allocates the first logical volume to a second logical volume that is a virtual logical volume that has been divided into at least two virtual areas. The storage control apparatus executes a first data movement processing for moving all data of the first logical volume to at least one pool volume other than the first logical volume, and allocates a real area of a movement destination of the data to a virtual area of an allocated destination of a real area of a movement source of the data as substitute for the real area in the first data movement processing.

Storage apparatus to which thin provisioning is applied and including logical volumes divided into real or virtual areas

A configuration management system for a storage system including a host computer, a storage device providing a storage area for data processed by the host computer, and a communication network connecting the host computer and the storage device communicatively is disclosed. The configuration management system comprises a system condition table storing a system condition, a storage configuration table storing storage configuration information, a performance table storing a performance condition indicating a storage performance. searching the system condition table is searched using the required system condition and the performance table is searched using the required performance condition. If the storage system satisfying the required conditions fails to be extracted, content of the required system condition is changed and searching of the system condition table and the performance table is carried out.

Configuration management system and configuration management method for storage system

By considering a device life and time needed for data migration, data stored in a storage apparatus is securely preserved until a retention term of each of the data. Multiple disk devicesA toC that store a data file generated by a service server apparatusare included. A migration managerof a management server apparatusacquires preservation period information that indicates a preservation period of the data file from the service server apparatus, and calculates a preservation term of the data file based on the preservation period information. The migration managerof the management server apparatusalso acquires data amount information of the data file from the service server apparatus, and calculates a necessary time needed for migrating the data file to other disk devices AA toC. When the preservation term comes later than an operation guarantee term recorded in advance for each of the disk devicesA toC, the migration managerof the management server apparatuscompares the end of the migration with the operation guarantee term, and determines the necessity of the migration.
