1 Overview of HP XP P9000 Performance Advisor Software HP XP P9000 Performance Advisor Software collects, monitors, and displays the performance of XP and P9000 disk arrays. HP XP P9000 Performance Advisor collects performance data for individual components such as LDEV, CHIP/CHA, ACP/DKA, DKC, and MP blades (applicable for only P9000 disk arrays).
2 General best practices for using Performance Advisor • For Performance Advisor and Command View AE to coexist, ensure that the following minimum prerequisites are met before you proceed with the Performance Advisor installation: ◦ 30 GB free space on hard drive ◦ 4 GHz CPU or Dual processor system with minimum 2 GHz CPU each ◦ 4 GB RAM • HP recommends that the host system communicate with a maximum of three disk arrays (XP and P9000 disk arrays) at a time.
3 Configuration and performance collection • HP recommends that you do not upgrade an HP XP P9000 Performance Advisor when a scheduled configuration collection or a manual configuration collection for an array is in progress. • During configuration data collection, if you want to know the percentage of CHIP port utilization (Micro Processor (MP)), HP recommends using the OutBand mode of configuration data collection.
Example configuration for a host agent that collects data for four XP24000 disk arrays at 2 minute collection interval with <10,000 LDEVs (combined from all four XP24000 disk arrays): • ◦ CPU: SUNW, UltraSPARC-T2 1165 MHz ◦ RAM: 8 GB ◦ SWAP:16 GB ◦ LAN speed: 1000 Mbps FD ◦ OS: Solaris v10 ◦ JAVA Heap Size: 1 GB Maximum number of LDEVs Table 1 (page 7) provides the list of tested configurations that HP recommends for using Performance Advisor.
4 Database configuration • Ensure that the Auto Grow option is enabled (select the Auto Grow check box on the Database – Configure screen). HP does not recommend changing the database size manually. The Auto Grow option when enabled changes the database size automatically based on the performance data collection rate. • Database growth size depends on the number of schedules, LDEVs, and the frequency of schedules.
5 Charts and reports • Do not generate charts or reports when the data purge or archival is in progress. • To improve charting and overall HP XP P9000 Performance Advisor GUI response, perform a manual purge, so that auto purge does not run during the time when HP XP P9000 Performance Advisor is most frequently used. • When determining if auto purge is running, check Event log.
6 Performance Advisor deployment The typical and recommended Performance Advisor – XP and P9000 disk arrays – host agent configurations are as shown in the following figures: Figure 1 Performance Advisor – XP array – host agent configuration 1 Figure 2 Performance Advisor – XP and P9500 disk array – host agent configuration 2 10 Performance Advisor deployment
