Abstract:
The storage system includes a first storage device, configured to be installed in a first site and providing a primary logical volume in which data received from a host computer is written; a second storage device, configured to be installed in a second site and providing a virtual logical volume, which has no structure for storing data received from the first storage system; and a third storage device, configured to be installed in a third site and providing a secondary logical volume in which data received from the second storage system is written. Data written in the primary logical volume of the first storage device are remote-copied to the secondary logical volume of the third storage device via the virtual logical volume of the second storage device.
