Figure 11 (Page 2 of 3). RACF EstimatedStorage Usage

Storage
Subpool Usage How to Estimate Size
ESQA RACF data sharing control area 300 (when enabled for sysplex communication)
Class descriptor table (CNSX) (number_of_IBM-defined_classes × 28) +
(number_of_IBM-defined_entries_in_router_table × 30) +
(number_of_customer_defined_classes × 58) + 26
For Security Server (RACF), there are 145 IBM-defined
classes and 167 IBM-defined entries in the router table, so
the size of the CNSX is 9096 +
(number_of_customer_defined_classes × 58). If you install a
PTF that adds entries, you will need to recalculate this
number.
LSQA ACEE and related storage
Notes:
1. Applications can place this storage
in a different subpool.
2. Applications can create multiple
ACEEs in this and other storage
subpools.
400 + installation_data_length +
terminal_installation_data_length +
application_installation_data + (52 for every 78 temporary
datasets, rounded up to the next multiple of 52)
If the address space has been dubbed an OpenEdition
process, then add: 52 +
(number_of_connected_groups_with_GIDs × 4)
Add 112 bytes if the user has CLAUTH for a class with a
POSIT value over 127.

profiles in a different storage
subpool.
