Using Utility Capacity on Demand

Utility Capacity on Demand (CoD) automatically provides additional processor capacity on a temporary basis within the shared processor pool.

Utility CoD use is measured in processor minute increments and is reported at the Utility CoD website. Payment is required based on the reported use of processor minutes. You must purchase and pay for an order that includes a quantity of Utility CoD billing features.

Each managed system has a reporting limit and a reporting threshold. These values are set by the Utility CoD Enablement Code. On managed systems with 1 - 4 inactive processor cores, the reporting threshold is 500 minutes, and the reporting limit is 1000 minutes. On managed systems with 5 - 16 inactive processor cores, the reporting threshold is 1000 minutes, and the reporting limit is 2000 minutes. If the number of inactive processor cores is more than 16, then the reporting threshold is 2500 minutes, and the reporting limit is 5000 minutes.

The HMC displays a message on the desktop when the number of unreported minutes reaches 90% of the reporting threshold. To ensure that you can continue to use your Utility CoD processor cores, you should report when your reporting threshold reaches 90%.
