STORAGE SYSTEM AND OPERATION METHOD OF STORAGE SYSTEM |
摘要 |
The present invention is able to improve the processing performance of a storage system by respectively virtualizing the external volumes (3) and enabling the shared use of such external volumes by a plurality of available virtualization storage devices (1, 2). By virtualizing and incorporating the external volume (3A) of an external storage device (3), a first virtualization storage device (1) is able to provide the volume to a host (4) as though it is an internal volume. When the load of the first virtualization storage device (1) 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 (7), the external volume (3A) relating to the selected logical volume is transferred from the first virtualization storage device (1) to the second virtualization storage device (2). |
