摘要： The present invention is able to improve the processing performance of a storage system by respectively virtualizing the external volumes and enabling the shared use of such external volumes by a plurality of available virtualization storage devices. By virtualizing and incorporating the external volume of an external storage device, a first virtualization storage device is able to provide the volume to a host as though it is an internal volume. When the load of the first virtualization storage device increases, a second virtualization storage device 2 is newly introduced, and connected to the storage system. When a transfer direction is issued from a management terminal, the external volume relating to the selected logical volume is transferred from the first virtualization storage device to the second virtualization storage device.

摘要： A DBMS performs a checkpoint process for maintaining consistency of data. A snapshot acquisition control program detects the checkpoint process externally to the DBMS and creates a snapshot in an external storage according to the timing of the checkpoint. Correspondence between checkpoints and snapshots is maintained in a CP-SH correspondence management table to make it possible to restore in a short time data at the time of an arbitrary checkpoint.

摘要： In a storage subsystem, performance tuning is performed with respect to whole logical devices including external storage subsystems that are not directly connected to host computers. Physical storage units presented by the external storage subsystems are defined as logical devices of the storage subsystem itself, and I/O processing requests from the host computers are relayed to those logical devices. At the time of relaying, I/O processing conditions are monitored. When there exists an external storage subsystem whose load is high, then, operating conditions of ports and processors are examined. In the case where the load can be reduced by changing the configuration of those ports and processors, the configuration is changed to reduce the load. In the case where the load can not be reduced, data is migrated from a logical device having a high load to a logical device having a sufficient performance.
