Abstract: A mechanism is provided for throttling power utilized by a set of power consumption devices using priority-aware power capping. Responsive to unassigned power budget remaining in the overall power budget after a minimum power budget value has been assigned to the child device based on an associated priority of the child device, an additional power budget value equal to a remaining priority-based exposed power demand value of the child device is assigned to the child device in response to the remaining unassigned power budget being greater than or equal to the remaining priority-based demanded power value thereby forming a total power budget for the child device. Responsive to design limitations of power distribution equipment in the data processing system or contractual limits of the data processing system being reached, a throttling is implemented by each child device based on the total power budget assigned to the child device.

Abstract: A mechanism is provided for statistical determination of power circuit connectivity based on signal detection in a circuit. Signal data from the circuit gathered and a determination is made as to whether a signal of interest is present in the gathered signal data from the circuit using a statistical analysis of the gathered signal data. The statistical analysis comprises using a mean current value and statistical deviation of the current value of the signal data over a predetermined period of time to compute a confidence range. The confidence range is compared to a first threshold and a second threshold. A determination is made that the signal is present in response to the confidence range being above the first threshold. A determination is made that the signal is not present in response to the confidence range being below the second threshold.

Current being consumed by the set of powered elements P on a branch circuit is measured and available current on the branch circuit is determined. A new total power cap for a current time period t is identified based on a current total power cap and the measured current.

A power cap of each powered element p is then dynamically set to the new power cap PC (p,t).

Abstract: A communications system is provided for direct communications between powered elements. A controller hub injects a first message via a modulated communication signal onto a branch circuit using a hub-side power line communication (PLC) coupler. An element-side PLC coupler associated with a powered element in a set of powered elements detects the first message and sends an interrupt to a mini-controller in the powered element. The mini-controller receives the interrupt from the element-side PLC coupler, extracts the first message using the element-side PLC coupler; reads a destination identifier in the first message; compares the destination identifier in the first message to a mini-controller identifier in the mini-controller; sends an acknowledgement message back to the controller hub in response to the destination identifier in the first message matching the mini-controller identifier, and forwards the first message to the powered element.
