Introduction
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 Figure 11 on page 193). 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.
