Table 2 XP External Storage requirements (continued)
Requirement Item
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 HP XP Snapshot Software, 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
NOTE: A LUN ID of a connected external volume should
be set in the range of 0 – 1,023. An external volume that
has a LUN ID equal to or larger than 1,024 cannot be
connected.
8 Maximum number of FC paths that can exist to one external
LU
2 TB (4,294,967,296 blocks) per external LU (OPEN-V) Maximum capacity of an external LU
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.
About 38 MB (77,760 blocks) per external LU
(non-OPEN-V) Minimum capacity of an external LU
When the volume's emulation type is OPEN-V, minimum
capacity is about 47 MB (96,000 blocks) per external LU.
Installing XP External Storage
To perform XP External Storage operations with XP Command View Advanced Edition Software
or Remote Web Console, you must install an XP External Storage license key.

following information is required:
•
Ports that can be set to external ports (see “External ports” (page 17) )
•
External array and LUs to map to the internal LDEVs (see “External LU to be mapped” (page 17) )
•
Configuration of external LU groups (see “External LU groups” (page 17) )
