Figure 3 Concept of XP External Storage

By mapping an external volume as an internal volume using XP External Storage as shown in Figure 3 (page 13), it becomes possible to operate the external volume using Remote Web Console as if it is a volume in the local storage system.

XP External Storage Components

Systems using XP External Storage usually contain the following components:

•Local storage system

•External storage system

•Remote Web Console computer

•XP External Storage

•External volume

•Internal volume, which is a virtual representation of an external volume

•LDEVs (Logical Devices) in an external volume

•Cross-subsystem path

•Mapping path

Figure 4 (page 14) illustrates the relations of the XP External Storage components.
