Abstract
A method for managing the power of a chassis includes receiving a plurality of modular information handling systems into the chassis, receiving a plurality of information handling resources into the chassis, virtualizing access of one of the modular information handling resources to two or more of the plurality of modular information handling systems, the modular information handling systems sharing the modular information handling resource, and, upon initialization of one of the information handling systems, determining power requirements of the shared information handling resource, receiving power requirements from the information handling systems, determining whether the power requirements from the information handling system includes power requirements of the shared information handling resource, subtracting the power requirements of the shared information handling resource from the power requirements of the information handling system to determine resultant power requirements, comparing the resultant power requirements with available power, and allowing operation of the information handling system.
