Introduction
HP XP P9000 Performance Advisor provides the overall configuration, performance, and utilization
summary of the XP and the P9000 disk arrays on the Array View screen (see
“Array View screen”
(page 172) ). 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 a P9000 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 a P9000 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 XP48, XP128, XP10000, XP12000,
and the XP20000 Disk Arrays. They are replaced by the CHAs and the DKAs for the XP24000
Disk Array and the P9000 disk arrays, such as the P9500.
