For installations with no prior service data, the task time reported
in SMF type 4, 5, 30, 34, and 35 records can be converted to service
units using the tables in CPU capacity table.
Examples of resource groups
- To give a department a “dedicated 4381” amount of
capacity, you can specify the following resource group:
- Name
- 4381-91E
- Description
- Capacity of a 4381
- Capacity Minimum
- 309
- Capacity Maximum
- 309
- To assure half the capacity of a 9672 Model Y96
system, with 9 physical CPs, to a service class, specify the following:
- Name
- HALFSYS3
- Description
- Preserve half of SYS3 (9672 Mod Y96)
- Capacity Maximum
- 24129
Since the 9672 Model Y96 has 5362 raw CPU service
units per second, with 9 physical CPs, 0.5 X 9 X 5362 is 24129. The
24129 is captured service units allocated to the address spaces in
the resource group.
