HP StorageWorks P9000 Performance Advisor Software v5.3 User and Troubleshooting Guide (T1789-96322, August 2011)

Viewing LDEV data
P9000 Performance Advisor displays the following data on the Array View LDEV screen for all the
LDEVs that belong to an XP or a P9000 disk array:
• The performance data of all the LDEVs
• The data on associated components, such as the following:
• The summary for individual RAID groups, which includes:
• RAID level
• Associated ACP pair
• Disk mech details
• Associated drive type and RPM rate
• The I/Os and MB/s data for individual CHIP ports
For an XP disk array, in addition to the above-mentioned, the total utilization of the individual ACP
pairs is also displayed.
For a P9000 disk array, in addition to the above-mentioned, the MP blade IDs are also displayed for
those MP blades that have LDEVs currently assigned to them.
To view the above-mentioned data for an XP or a P9000 disk array, select LDEV in the component
selection tree for the corresponding XP or P9000 disk array.
IMPORTANT:
Since, the CHIP/CHA and ACP/DKA MPs are moved to the MP blades in the P9000 disk arrays,
their MP utilization metrics are not applicable for the P9000 disk arrays. For more information, see
“Viewing MP blade utilization for P9000 disk arrays” on page 224.
