Abstract: Examples to restore a trusted backup configuration for a node. Example techniques include failover to an alternate firmware of the node, in response to an unverifiable condition of an existing firmware of the node. The node may validate a first configuration file stored in the node. The first configuration file includes a first backup configuration. The node may validate a second configuration file stored in the node based on the validation of the first configuration file. The second configuration file includes a second backup configuration. In response to the validation of at least one of the first configuration file and the second configuration file, the node may select one of the first backup configuration and the second backup configuration, and apply the selected backup configuration to the node.

Abstract: Examples disclosed herein relate to initializing a fan speed of a computing device using a high-water value when a pre-runtime event occurs. A management controller (MC) receives sensor data from sensors of the computing device. A fan speed of a fan is controlled using a fan control value based on the sensor data. The fan control value is monitored to determine a high-water value of the fan control value. The high-water value is stored in a location that is accessible by a pre-runtime fan control engine of the computing device. In response to a pre-runtime event, the fan speed is initialized to a speed using the high-water value.
