HP StorageWorks P9000 Performance Advisor Software v5.4 Install Guide (T1789-96330, April 2012)

1. Check the supported configuration for the management station and the host agent. For more
information, see Verifying the supported configurations for P9000 Performance Advisor and
Verifying the supported configurations for P9000 Performance Advisor host agents.
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.
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 manage-
ment server and host agent:

LDEVs30 mins65K411
LDEVs45 mins130K821
LDEVs60 mins148K1341
For collecting DKC and the port data, you must set the data collection frequency to 10 minutes.
• To estimate management station's disk volume space required for the P9000 Performance Advisor
database:
• HP recommends that there be at least a week's historic data available when you are forecasting
using charts or alarms.
• Determining disk space requirements:
Use the following formula to determine the disk space requirements for P9000 Performance
Advisor on a daily basis. The factors that influence the output are the number of: XP and P9000
disk arrays, LDEVs, ports, and DKC components. Also, the performance data collection and
frequency influence the output.
Free_Space (MB/day for one array) = [(SECONDS_PER_DAY / Ldev_Collec-
tion_frequency) * LDEVs * Ldev_Space ] + [(SECONDS_PER_DAY /
Port_Collection_ frequency) * PORTs * Port_Space] + [(SECONDS_PER_DAY/
Dkc_Collection_ frequency) * Dkc_Space]
where:
• Free_Space (MB/day) = Total free disk space (in MB) required for a day
• LDEVs = Total number of LDEVs in an XP or a P9000 disk array (includes journal volumes,
pool volumes, external volumes, and so on)
• PORTs = Total number of ports for an XP or a P9000 disk array
• Ldev_Collection_frequency = Collection frequency for LDEVs (in seconds)
• Port_Collection_frequency = Collection frequency for ports (in seconds)
• Dkc_Collection_ frequency = Collection frequency for DKC (in seconds)
• Ldev_Space ( per Ldev) = 0.0002 MB
• Port_Space (per port) = 0.00008 MB
• Dkc_Space (per collection) = 0.0002 MB
• SECONDS_PER_DAY = 86400
