HP XP P9000 Performance Advisor v5.5 Software Best Practices Guide (T1789-96343, February 2013)
◦ 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.
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.

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 2 (page 8) provides the list of tested java heap size configurations that HP recommends
on the management station and host agents system.
