HP XP P9000 Performance Advisor v6.0 Software Best Practices Guide

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 7) provides the list of tested java heap size configurations that HP recommends

on the management station and host agents 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.

> 30,000 LDEVs1

Set an appropriate value or use the

default value that is set on the

management station.
