HP StorageWorks XP Performance Advisor Software v4.6 Release Notes (T1789-96097, June 2010)

• The ThP Pool main category under Charts displays the associated DKAs in addition to the RAID

Groups and their physical LDEVs, host groups and their virtual volumes. The following metrics are

introduced to monitor a ThP pool's utilization:

• Frontend Vs. Backend Hit Ratio: It is the ratio of the total frontend I/Os on a ThP pool versus

the total backend tracks associated with a ThP pool.

• ACP Pair Util Total: Provides ACP utilization caused by the I/O cache miss, where frontend

I/Os happening on a ThP pool are received at the array backend. ACP utilization also correlates

to the utilization of RAID groups associated with a ThP pool.

• LDEV RG Utilization: The utilization of LDEVs that form VVols and belong to a RAID group that

is associated with a ThP pool.

• Overall RAID Group Utilization: When a RAID group is associated with a ThP pool, this metric

provides the extent of RAID group utilization caused by I/Os on a ThP pool.

Points to note

This section describes important information related to XP Performance Advisor v4.6.

• Outband is the preferred and default mode of configuration data collection for an XP Disk Array

of type XP24000, XP20000, XP12000, or XP10000. If the Service Processor (SVP) on the XP Disk

Array is accessible and registered with your management station, HP recommends that you use

the Outband mode of configuration data collection. XP Performance Advisor receives the accurate

internal raw disk capacity from the XP Disk Array (same as shown by the Remote Web Console

(RWC)) through the Outband mode.
