Abstract:
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.
