An information handling system includes first and second power supplies, a chassis BMC, and a sled. The power supplies each assert a power good indication when the power supply is providing power on a power rail. The chassis BMC receives the power good indications and asserts a loss of redundancy indication when one of the power good indications is deasserted. The sled includes a sled BMC and a host processing system. The sled receives the loss of redundancy indication and in response, asserts a processor over temperature indication to the host processing system. When both power good indications are asserted, the chassis BMC directs the sled BMC to operate the host processing system in accordance with a normal operation sled current limit. When one of the power good indications is deasserted, the chassis BMC directs the sled BMC to operate the host processing system in accordance with a reduced power operation sled current limit. The reduced power operation sled current limit is a lower limit than the normal operation sled current limit.

Methods and systems for power management are disclosed. The disclosed power management method and systems may improve the likelihood of data processing systems providing desired computer implemented services while meeting power budget goals and/or other types of goals regarding power consumption, use, and/or provisioning. To improve the likelihood of the power budgets being met, the system may dynamically update power allocations to various components of data processing systems. The power allocations may be dynamically allocated by predicting how changes in existing power allocations may impact the ability of the data processing system to service power allocation requests. If it appears that changes in one or more existing power allocations may allow a power allocation request to be serviced, then the power allocations may be dynamically reallocated to free allocable power. The freed allocable power may be used to service the power allocation.

A system for controlling power to a complex system, comprising a plurality of processors, one or more power supply unit, each power supply unit including an overcurrent warning system and a baseboard management controller coupled to the plurality of processors and the one or more power supply unit, wherein the baseboard management controller is configured to determine whether a power cap control has been enabled and to adjust an overcurrent warning threshold of the overcurrent warning system.
