Introduction
Every XP or XP7 disk array that is connected to an instance of HP XP7 Performance Advisor must
have a valid HP XP7 Performance Advisor license to monitor the internal raw disk capacity of the
XP disk array or the usable capacity of the P9500 and XP7 disk array. HP XP7 Performance Advisor
monitors the internal raw disk capacity in an XP disk array or the usable capacity in a P9500 disk
array for which a license is generated at the Hewlett-Packard Authorization Center (HPAC) website
(URL:
). To monitor internal raw disk capacities, generate Permanent
licenses. To monitor usable capacities, you can generate Permanent and Meter based Term licenses.
For more information, see
“HP XP7 Performance Advisor licenses” (page 22)
The internal raw disk capacity refers to the total capacity of all the RAID groups created on the XP
disk array. It excludes the disk capacity occupied by the external RAID groups and pool volumes,
such as the thin provisioning pools and the virtual volumes.
The usable capacity is calculated as the sum of the following: Total allocated LDEV capacity + total
unallocated LDEV capacity + reserved capacity.
•
Total allocated LDEV capacity includes the allocated internal LDEVs
•
Total unallocated LDEV capacity includes the unallocated internal LDEVs
•
Reserved capacity includes the pool volumes, such as thin provisioning, snapshot, and
continuous access journal volumes
So, usable capacity = Internal LDEVs —(External Volumes + Virtual Volumes)
