    Abstract: Periods of interoperability of sideband buses prevent effective management of managed devices by a remote access controller. Embodiments avoid periods of inoperability of sideband buses and recover the sideband bus without resetting the managed devices or the IHS (Information Handling System). The remote access controller configures timer and transmits the timer to a managed device. The managed device monitors the sideband for messages for the remote access controller. If no messages are received before expiration of the timer, the managed device resets its sideband bus endpoint, without resetting the managed device.

    Abstract: An information handling system includes a power assist unit (PAU) and a baseboard management controller (BMC). The PAU is coupled to a power rail and includes a power storage element, a converter coupled to the power storage element and the power rail, and a controller. The controller receives a current level indication indicating a current provided to a load of the information handling system, directs the converter to provide power from the power storage element to the power rail when the current level indication is greater than a threshold level, directs the converter charge the power storage element from the power rail when the current level indication is greater than the threshold level, and provides a charge level indication that indicates an amount of charge on the power storage unit. The BMC receives the charge level indication, and sets a peak power limit for the information handling system based on the charge level indication.

    Abstract: An information handling system (IHS) includes a power supply unit (PSU) and a power assist unit (PAU). The PSU provides power to a power rail at a first voltage level when he IHS is in a first platform state, and at a second voltage level when the IHS is in a second platform state. The PAU includes a power storage element, a converter coupled to the power storage element and to the power rail, and a controller. The controller determines whether the IHS is operating in the first or second platform state, directs the converter to provide power from the power storage element to the power rail at the first voltage level when the information handling system is in the first platform state, and to direct the converter to provide power from the power storage element to the power rail at the second voltage level when the information handling system is in the second platform state.

  • Publication number: 20200133363
    Abstract: An information handling system includes active and standby power supplies and a power assist unit. The power supplies provide power to a power rail. The standby power supply supplies current to the power rail when a current demanded by a load is greater than a proportion of a maximum current demand, and is off when the current demand is less than the proportion. The power assist unit is coupled to the power rail and includes a power storage element, a converter coupled to the power storage element and to the power rail, and a controller. The controller receives a current level indication that indicates the current demanded by the load, and in response to the current level indication indicating that the current demand peaks to greater than the proportion of the maximum current demand, directs the converter to provide power from the power storage element to the power rail to prevent the second power supply unit from turning on.

    Abstract: Examples described herein relate to allocation of power to engines and a surplus power available for use by one or more engines. A power management controller reserves power for one or more processors of the offload engine and provides a surplus power level. Based on a request for a workload performance by the first processor, the power management controller provides power to a processor based on the reserved power for the processor. Allocation of the surplus power can be made based on a priority of a workload relative to other workloads.
