Abstract:
1. A system comprising: a group of multiple information handling system nodes pooled together in a common credit/debit power pool; one or more common sources of power coupled to provide power to each node of the group of information handling system nodes; and at least one processing device coupled to each given one of the group of multiple information handling system nodes and configured to: where the processing devices of the group of information handling system nodes are configured to communicate among themselves to dynamically allocate and reallocate power between the individual nodes of the group of information handling system nodes in a distributed peer-to-peer manner based on the real time monitored power consumption and available amount of power in the power pool such that the total power provided to all of the information handling system nodes never exceeds the group power limit by temporarily decreasing by a given amount the assigned power cap of at least one of the information handling system nodes that has been consuming a lower real time monitored power amount than its assigned power cap, and by temporarily increasing by at least a portion of the decreased given amount the assigned power cap of at least one other one of the information handling system nodes that has been consuming a real time monitored power amount that is equal to its assigned power cap such that the total of the assigned power caps for all of the information handling system nodes never exceeds the assigned total group power limit.
