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. • Avoid toggling the configuration collection between OutBand and InBand modes.
◦ Minimum 100 MB LAN speed ◦ Maximum 65,000 LDEVS for all the XP and P9000 disk arrays whose data is collected by the host agent ◦ Maximum four XP and P9000 disk arrays per host agent, if none of the disk arrays have more than 2,500 LDEVs (total of 10,000) ◦ Minimum 512 MB heap size NOTE: All the above depends on other applications running on the host agent.
Table 2 Java heap size settings Host agents Number of LDEVs Set Java heap size 1 < 30,000 LDEVs 1024MB 1 > 30,000 LDEVs 1536MB NOTE: Systems with low main memory (less than 2GB) might not be able to allocate 1536MB of memory to Java, due to which the Java application will not start. In such a case, it is suggested that you set the heap size value to an MB value lesser than 1536MB or use the default value set on the host system.
4 Database configuration • Ensure that the Auto Grow option is enabled (select the Auto Grow checkbox 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 11
