1 Overview of HP StorageWorks P9000 Performance Advisor HP StorageWorks P9000 Performance Advisor Software collects, monitors, and displays the performance of XP and P9000 disk arrays. 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).
IMPORTANT: P9000 Performance Advisor is called XP Performance Advisor in the pre-5.0 versions. P9000Watch and P9000Sketch are called XPWatch and XPSketch in the pre-5.0 versions.
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 2GHz 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.
General best practices for using Performance Advisor
3 Configuration and performance collection • 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. Every time you toggle between OutBand and InBand modes, you need to delete the existing performance schedules and create new schedules after the configuration collection is complete.
• 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 512MB heap size NOTE: All the above depends on other applications running on the host agent.
Host agents Number of LDEVs Set Java heap size Management Station Number of LDEVs Set Java heap size 1 < 64,000 LDEVs Set an appropriate value or use the default value that is set on the management station.
Configuration and performance collection
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. • Occasionally visit the Database – Configure screen to view current database size and disk space for better capacity planning.
Database configuration
5 Charts and reports • Do not generate charts or reports when the data purge or archival is in progress. • To improve charting and overall P9000 Performance Advisor GUI response, perform a manual purge, so that auto purge does not run during the time when P9000 Performance Advisor is most frequently used. • When determining if auto purge is running, check Event log. • Reports can be generated to view array performance data for a specified duration.
Charts and reports
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 .
