System and method for throttling power in one or more information handling systems
First Claim
1. A method of controlling power consumption of a group of information handling systems that use a common power source, the method comprising:
- storing an aggregate power limit for a group of information handling systems, the storing comprising storing trip point data that corresponds to a current trip point for a shared circuit breaker;
monitoring individual power consumption levels for the information handling systems, the monitoring comprising monitoring computers that draw power from the shared circuit breaker;
automatically calculating an aggregate power consumption for the group of information handling systems, based on the individual power consumption levels;
automatically determining whether the aggregate power consumption for the group of information handling systems approaches the aggregate power limit;
in response to determining that the aggregate power consumption approaches the aggregate power limit, automatically selecting at least one information handling system among the group for power reduction; and
in response to determining that the aggregate power consumption approaches the aggregate power limit, automatically communicating with the selected information handling system to cause the selected information handling system to reduce power consumption.

Abstract
An information handling system includes support for dynamic power throttling. In one embodiment, an information handling system includes power level detection and power control modules. The power level detection module may monitor power consumption for the information handling system and may automatically transmit power level data to a power level manager, based on the monitored power consumption. The power control module may receive power control data from the power level manager. The power control module may also automatically adjust power consumption of the information handling system, in accordance with the power control data received from the power level manager. In another embodiment, an information handling system may include an interface and a power level manager. The power level manager may receive power information for computers via the interface, may automatically compute an adjusted power threshold setting, and may automatically transmit the adjusted power threshold setting to a computer.
