Abstract: Systems, methods, and non-transitory computer-readable storage media for smart power clamping of a redundant power supply. A system configured according to this disclosure can measure, at a baseboard management controller, a system power consumption which indicates total power being delivered by a first power supply unit and a second power supply unit. The system can determine that the system power consumption exceeds a system power consumption capacity and, in response to the determination, communicate a power clamping signal to a processor, resulting in a reduced system power consumption. The system can further identify that the reduced system power consumption exceeds the system power consumption capacity and initiate a hardware throttling of at least one of the first power supply unit and the second power supply unit.

Abstract: An apparatus may include a chassis that can receive a sled and a locking mechanism. The locking mechanism can mechanically lock the sled to the chassis to prevent a sudden power loss that can be caused from an unexpected removal of the sled from the chassis. To avoid a sudden power loss, a voltage-sensing electrical switch lock can be implemented to the chassis to mechanically lock the sled to the chassis until the sled is ready to be removed. The sled may include one or more computing devices that need to be inactive before removing the sled. The apparatus includes a controller that may detect whether at least one of computing devices in the sled are in an active state or in an inactive state. Based on the determination of the state of the computing devices in the sled, the controller may activate the locking mechanism or de-active locking mechanism.

Abstract: In some implementations, a rack management controller can dynamically manage power supply units in a server rack system. For example, the rack management controller can determine how many power supply units should be powered on based on the power requirements of the server rack system. The management controller can configure a power management controller to turn on the determined number of power supply units. The rack management controller can receive status signals from the power supply units in the server rack. The rack management controller can detect when a power supply unit fails based on the status signals. The rack management controller can dynamically reconfigure the power management controller to replace the failed power supply unit by turning on a reserved power supply unit.
