External Storage XP requirements
Installing External Storage XP
To perform External Storage XP operations with Command View XP or XP Remote Web Console, you must
install an External Storage XP license key.
1. Start Command View XP or XP Remote Web Console for the local array.
2. Enable the External Storage XP options in Command View XP or XP Remote Web Console and on
each External Storage XP array.
For instructions, see the HP StorageWorks Command View XP user guide for XP Disk Arrays or the
HP StorageWorks XP Remote Web Console user guide for XP12000/XP10000/SVS200.
Preparing for External Storage XP settings
Before using External Storage XP, collect the information necessary for defining its settings. The following
information is required:
Table 3 External Storage XP requirements
Item Requirement
Required products
• HPStorageWorks Command View XP version 2.0 or later, or
XP Remote Web Console
• HP StorageWorks LUN Configuration and Security Manager
XP (for
setup)
• HP StorageWorks RAID Manager XP version 01.12.06 or later
(if Business Copy XP is used)
Maximum number of external LUs
addressable per local array port
1,024 per port
Maximum number of external LUs that can
be connected
• For the XP12000, 15,360 volumes can be connected
• For the XP10000/SVS200, 8,192 volumes can be connected
• 1,024 volumes can be connected per port
NOTE: If you use Snapshot XP, the number of external LUs that can
be connected is as follows:
• For the XP12000:
Number of external LUs + Number of virtual LUs ≤15,360
• For the XP10000/SVS200:
Number of external LUs + Number of virtual LUs ≤8,192
Maximum number of FC paths that can exist
to one external LU
8
Maximum capacity of an external LU 2 TB (4,294,967,296 blocks) per external LU (OPEN-V)
If you specify an external LU that is larger than 2 TB, you can only
access data stored in the field up to 2 TB.
Minimum capacity of an external LU About 38 MB (77,760 blocks) per external LU (non-OPEN-V)
When the volume’s emulation type is OPEN-V, minimum capacity
is about 47 MB (96,000 blocks) per external LU.
