Figure 1 Unifying copy operations between different storage systems
Unifying connections from a host to different storage systems
When a system has multiple storage systems, a host usually needs to connect to all storage systems.
When a system administrator configures the connections from a host to volumes, they need to
follow the different instructions depending on the storage systems.
If you install External Storage, a system administrator only needs to configure the connection from
a host to the P9500 storage system. After the configuration is completed, a host can manipulate
volumes in the external storage system in the same way as volumes in the P9500 storage system.
