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.
