Branch circuit power measurement and dynamic power distribution |
| 摘要 |
A mechanism is provided for dynamically changing power caps for a set of powered elements. Current being consumed by the set of powered elements P on a branch circuit is measured and available current on the branch circuit is determined. A new total power cap for a current time period t is identified based on a current total power cap and the measured current. A difference in total power caps (ΔTPC) is determined and, for each powered element p in the set of powered elements P at the current time period, a new power cap PC (p,t) is determined based on the previous power cap PC(p,t−1) and the difference of the total power caps to the set of powered elements P. A power cap of each powered element p is then dynamically set to the new power cap PC (p,t). |

1. A method, in a data processing system, for dynamically changing power caps for a set of powered elements, the method comprising:
measuring current being consumed by the set of powered elements P on a branch circuit; determining available current on the branch circuit; identifying a new total power cap for a current time period t based on a current total power cap and the measured current; determining a difference in total power caps (ΔTPC); for each powered element p in the set of powered elements P at the current period, determining a new power cap PC (p,t) based on the previous power cap PC(p,t−1) and the difference of the total power caps to the set of powered elements P; and dynamically setting a power cap of each powered element p to the new power cap PC (p,t). |
