Use this window to activate, deactivate, or change the number of Utility Capacity on Demand (Utility CoD) processors. You can also set, reset, or disable the processor minute usage limit for Utility CoD.
Utility CoD allows you to activate the inactive processors that are installed on your managed system to meet the variable workload demands of your business. When you use Utility CoD, activated Utility CoD processors are placed in the default shared processor pool and are used only as needed by uncapped partitions. If all non-Utility CoD processors in the default shared processor pool are being used, and one or more uncapped partitions require additional resources, then the managed system allows the uncapped partitions to use one Utility CoD processor for one minute, and one Utility CoD processor minute of use is recorded. The managed system continues to use this Utility CoD processor and record processor minutes until the Utility CoD processor is no longer needed. The managed system continuously monitors the processor utilization within the default shared processor pool. If additional processor resources are needed, the managed system automatically uses additional Utility CoD processors and records processor minutes for those processors. You pay only for the number of processor minutes that the Utility CoD processors are used. Optionally, you may prepay for Utility CoD usage.
