Typically, if a system consists of multiple storage systems, the host must be connected to each of the storage systems. When configuring the connections from the host to the volumes, the system administrator must follow specific instructions for each of the storage systems.
With Universal Volume Manager, the administrator configures the connection from the host to your storage system, and then uses mapped volumes in an external storage system in the same way as volumes in the local storage system.
With Universal Volume Manager, you can perform all procedures in external storage with the same software as when you use the local storage system.
For example, you can use a replication program to perform copy operations between the local storage system and external systems, including the following:
- Copying data from a volume in the local storage system to a volume in the external system
- Copying data from a volume in one external system to a volume in another external system
This image shows the copy operations before and after installation of Universal Volume Manager.
