Using SMF task time

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.
