XP External Storage
XP External Storage provides the virtualization of a multi-tiered storage area network comprised
of heterogeneous storage systems. It enables the operation of multiple storage systems connected
to an HP XP storage system as if they were all one storage system and provides common
management tools and software. The shared storage capacity comprised of external storage
volumes can be used with storage system-based software for data migration and replication, as
well as any host-based application. Combined with HP StorageWorks XP Auto LUN Software, XP
External Storage provides a data lifecycle management solution across multiple tiers of storage.
The key features and benefits of XP External Storage include:
•
Virtualizes external storage attached to the XP storage system
•
Enables deployment of multi-tiered storage
•
Integrates heterogeneous systems
•
Creates extended storage capacity independent of physical location
•
Creates new opportunities based on enhanced capability of existing business continuity
software and management tools to manage external storage devices
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 that you use.
If you install XP External Storage, you can perform the following copy operations in the same way
as when you copy data between volumes in the XP storage system.
•
To copy data between a volume in the XP 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.
