Abstract: A power supply comprising a hardware interface having conductive contacts and conforming to a power supply design standard comprising a pin-out definition specifying that a first conductive contact is to be dedicated to communicating first information of a first type. The power supply comprises first, second, and third circuitry. The first circuitry is to determine the first information. The second circuitry is to determine second information of a second type, wherein the second type of information is other than the first type. The third circuitry is to send, via the first conductive contact, a communication comprising the first information and the second information. In embodiments, a PCB comprises a connector to couple the PCB to the power supply via an interconnect to be coupled to the hardware interface, and an IC to receive the communication, and identify the first and second information.

Abstract: A system detects a powerdown event, such as a power loss event, and performs a flush of volatile memory to persistent memory during a powerdown sequence. The system includes an energy backup device to power the system during the powerdown sequence. The system is configurable with optional settings that configure the powerdown sequence specific to a type of the energy backup device.

Abstract: Techniques and mechanisms for providing power telemetry information which indicates a total load current from one or more power supply units (PSUs). In an embodiment, a device is coupled to receive a first signal from the current share bus which is coupled to each of multiple PSUs. A voltage level of the first signal represents a target amount of current to be output by each of the one or more PSUs. A second signal is generated based on both the first signal, and on an indication of a scale according to which a primary PSU of the one or more PSUs represents a target amount of current. In another embodiment, an amplification is performed, based on the second signal and on a total number of the one or more PSUs, to generate an Isys signal which indicates a total load current output by the one or more PSUs.
