XP External Storage Software
External Storage is a program product that enables you to operate multiple storage systems, including
the HP StorageWorks XP24000 Disk Array, as if they are all in one storage system. This allows system
administrators to easily manage different types of multiple storage systems.
For example, External Storage enables you:
•
To unify copy operations between different storage systems.
•
To unify connections from a host to different storage systems.
The following subsections explain how the copy operations and the host connection will change after
Universal Volume Manager is installed.
Unifying Copy Operations between Different Storage Systems
When you copy data between different storage systems, the copy operations are usually different
depending on the storage system which you use.
If you install External Storage, you can perform the following copy operations in the same way as when
you copy data between volumes in the storage system.
•
To copy data between a volume in the storage system and a volume in an external storage system.
•
To copy data between a volume in an external storage system and a volume in another external
storage system.
