HP XP P9000 Performance Advisor Software v5.5 User Guide (T1789-96337, Februrary 2013)

IMPORTANT:
• The LDEV table does not display hyperlinks in the ACP Pair ID and ACP Pair Util fields for RAID
groups spanning across multiple ACP pairs. Hence, no chart for the same can be created.
• For a P9000 disk array, the LDEV table does not display the ACP Pair Util field for RAID
groups. So, a chart for the ACP pair utilization metrics cannot be plotted.
• An XP24000 type array has 32 CHIPs, 8 ACP pairs, and 4 MPs per port, an XP20000 type
array has 8 CHIPs, 4 ACPs and 4 MPs per port.
• If configuration data is collected through the inband mode for array configured with external
storage volumes, the RAID group information of the external storage volume is displayed as
Ext-RdGp. All volumes of the external array group is considered as a single non-existing (virtual)
group, is termed as the External RAID Group and is denoted by Ext-RdGp. Performance data
is collected for all the volumes.
• All virtual volumes that are not associated with any pool, do not have RAID group information,
and of unknown type, are considered as a single non-existing (virtual) volume group. This
single non-existing (virtual) volume group is denoted as VVol-Grp in the RG column in the LDEV
table and Performance data is collected for all these volumes.
Viewing SLPR information
IMPORTANT: This section is applicable only for the XP disk arrays.
Click a SLPR value in the LDEV table to view the detail view for that SLPR in a separate browser
window. In the SLPR window, the line above the table indicates the hierarchical information of the
selected SLPR. The SLPR view includes two tabs, the CLPR tab and the Ports tab.
The CLPR tab displays the following details for each CLPR in the selected SLPR:
• Cache size
• write pending data
• Sidefile usage data
• Read hits data
Click a CLPR to view the associated details. For more information, see “CLPR detail view” (page 227).
The Ports tab displays the following details for each port associated with the selected SLPR:
• Maximum IO/s
• Average IO/s
• Minimum IO/s
• Maximum MB/s
NOTE: By default, the value displayed is 0 for arrays that do not support SLPR or CLPR.
