System Requirements

The system requirements for XP External Storage are:

•HP XP storage system (First storage system)

All the necessary hardware and microcode required for XP External Storage operations must be installed and enabled. In this user's guide, the first storage system is called local storage system.

•Storage system other than the first storage system

A second storage system must be available and operate as an external storage system. The kinds of storage systems that can be used as an external storage system include HP StorageWorks EVA storage systems, HP StorageWorks MSA storage systems, and other similar storage systems. For detailed information on the storage systems that can be used as the external storage system, see “Storage Systems Supported as External Storage Systems” (page 37).

•Remote Web Console computer (user-supplied computer)

See the HP StorageWorks XP24000/XP20000 Remote Web Console User Guide for instructions on installing and using the Remote Web Console computer.

NOTE: You must operate the Remote Web Console computer in Modify mode to perform XP External Storage operations. Users in View mode can only view XP External Storage information.

•License key for XP External Storage program product You need a license key to install XP External Storage.

Storage Systems Supported as External Storage Systems

For the storage systems that are currently supported as external storage, contact HP.
