To facilitate the management of a storage system that uses a flash memory as a storage area. A controller of the storage system provided with a flash memory chip manages a surplus capacity value of the flash memory chip, and transmits a value based on the surplus capacity value to a management server, on the basis of at least one of a definition of a parity group, a definition of an internal LU, and a definition of a logical unit. The management server displays a state of the storage system by using the received value based on the surplus capacity value.

Method for managing storage system using flash memory, and computer

Pairs are formed from a plurality of dispersed volumes and copying between the volumes is conducted by a series of remote operations from a management server. A management serverinstructs the generation of configuration setting filesto host computersselected so as to form copy pairs. If the configuration setting files are generated by host agents, the management serverinstructs copy start to a host computerhaving a primary volume. The host agentgenerates a prescribed command via a copy pair control moduleand causes a storage subsystemto execute copying between the volumes. When copying is completed, the management serveracquires the newest storage configuration information from the storage subsystemand updates configuration information DB

Storage system and setting method for storage configuration information

A method of allocating storage areas, intended to reserve the storage areas formed on a storage device for storing data, this method including the steps of: registering beforehand as a storage configuration information table, information on multiple storage areas to be managed and on the position where the storage device is installed; registering information on the purposes of use and positions of the storage areas beforehand as a position management table; acquiring position information from the position management tablein accordance with an allocation request for a storage area associated with the purpose of use; selecting an unallocated storage area from the storage configuration information tablewith reference to the position information; and sending information on a selected area to a client from which the allocation request was issued.
