HP XP P9000 Performance Advisor Software v5.5 Install Guide (T1789-96339, February 2013)

Collecting information about the XP and the P9000 disk arrays that you will monitor
1. Determine the number of logical devices (LDEVs) for each XP and P9000 disk arrays.
2. Determine how frequently you want to access data from the XP and the P9000 disk arrays.
IMPORTANT: The rate of data collection can affect the loads seen by the XP and the P9000
disk arrays, and the management station.
HP XP P9000 Performance Advisor provides the following types of data collection:
• Configuration data collection:
The frequency of configuration data collection depends on how often you change the
configuration of an XP or a P9000 disk array. For example, if you add a LUN to an XP or a
P9000 disk array every week, you might collect configuration data at least once a week to
see the changes reflected in your HP XP P9000 Performance Advisor database.
• Performance data collection:
For troubleshooting the XP or the P9000 disk array performance issues, HP recommends
a collection frequency of 1 to 3 minutes.
◦
IMPORTANT: Frequent collection increases the load on the XP and the P9000 disk
arrays and also the management station. For real-time troubleshooting, HP recommends
using HP XP P9000Watch, which is one of the utilities included in HP XP P9000
Performance Advisor to collect real-time performance data for troubleshooting purpose.
◦ For general monitoring and forecasting resource utilization, HP recommends a collection
frequency of 5 - 30 minutes.
Determining the management station and host requirements
Follow these steps to determine your management station and host setup requirements:
1. Check the supported configuration for the management station and the host agent. For more
information, see “Verifying the supported configurations for HP XP P9000 Performance Advisor”
(page 28) and “Verifying the supported configurations for HP XP P9000 Performance Advisor
host agents” (page 37).
2. Increase the management station and the host agent configuration based on the number of
LDEVs you require and the collection frequencies you want to set. For more information, see
“Estimating the required configuration” (page 24).
Estimating the required configuration
The following items can help you estimate the configuration you will need:
• To estimate the number of XP and the P9000 disk arrays that can be supported with one
