HP StorageWorks P9000 Performance Advisor Software v5.4 Best Practices Guide (T1789-96334, April 2012)
• 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.
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: 8GB
• SWAP:16GB
• LAN speed: 1000 Mbps FD
• OS: Solaris v10
• JAVA Heap Size: 1GB
• Maximum number of LDEVs
Table 1 provides the list of tested configurations that HP recommends for using Performance Advisor.

For DKC and Ports, you can set the data collection frequency to 10 minutes.
• A maximum of six disk arrays can be managed from a single host agent.
• A maximum of 13 disk arrays can be managed by one management station.
• Maximum java heap size setting
Table 1 provides the list of tested java heap size configurations that HP recommends on the
management station and host system.

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.
