Introduction
Every XP or P9000 disk array that is connected to an instance of P9000 Performance Advisor must
have a valid P9000 Performance Advisor license to monitor the internal raw disk capacity of the XP
disk array or the usable capacity of the P9500 disk array. P9000 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:
http://
webkey.external.hp.com ). 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
P9000 Performance Advisor licenses .
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.
NOTE:
If there are unprocessed RAID groups (those without LDEVs) and you see a difference between the
actual internal raw disk capacity and the value displayed in P9000 Performance Advisor, HP
recommends that you use outband mode of configuration data collection to get the accurate data.
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
