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 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 XP External Storage, a system administrator only needs to configure the connection from a host to the XP 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 XP storage system.
