Introduction
HP XP7 Performance Advisor provides the overall configuration, performance, and utilization
summary of the XP and the XP7 disk arrays on the Array View screen (see “Array View
screen” (page 174)). The data is displayed from the last performance data collection time stamp
and includes the following:
• The configuration and component distribution summary.
• The performance summary, which includes the average performance of the frontend and the
backend components, Cache, and CLPR for an XP disk array.
In addition to the above-mentioned, the continuous access data and average utilization of
each MP blade is also displayed for an P9500/XP7 disk array.
• The utilization summary, which includes the total utilization of the Cache, Bus (cache memory
and shared memory), ACP, and the CHIP for an XP disk array.
The utilization summary for an P9500/XP7 array includes the total utilization of the Cache,
Bus (cache memory and shared memory), and the MP blade.
From the high level summary, you can further drill down to view the performance data of the
individual CHIPs or CHAs, ACPs or DKAs, MP blades, LDEVs, RAID groups, ports, ThP and smart
pools.
NOTE: The CHIPs and ACPs are applicable only for the XP10000, XP12000, and the
XP20000 Disk Arrays. They are replaced by the CHAs and the DKAs for the XP24000 and
P9500 disk arrays.
