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.
