Determining disk space requirements

Use the following formula to determine the disk space requirements for P9000 Performance Advisor
on a day basis. The factors that influence the output are the number of arrays, LDEVs, ports, DKC
components, performance data collection, and collection frequency:

Free_Space (MB/day for one array) = [(SECONDS_PER_DAY /

Ldev_Collection_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)
