摘要： An Information Handling System (IHS) includes multiple hardware devices, and a baseboard Management Controller (BMC) in communication with the plurality of hardware devices. The BMC includes executable instructions for monitoring a parameter of one or more of the hardware devices of the IHS when a custom BMC firmware stack is executed on the BMC. The instructions that monitor the parameter are separate and distinct from the instructions of the custom BMC firmware stack. When the parameter exceeds a specified threshold, the instructions are further executed to control the BMC to perform one or more operations to remediate the excessive parameter.

摘要： A method and information handling system (IHS) for controlling an IHS in response to an environmental event includes a management controller dynamically polling at least one environmental event source for environmental event data. The environmental event data is received from the environmental event source. A first environmental event value is identified within the environmental event data. The method further includes determining if the first environmental event value is outside of a threshold specification. In response to the first environmental event value being outside of the threshold specification, a first action associated with the first environmental event value is identified. The IHS is triggered to perform the first action.

摘要： An Information Handling System (IHS) includes multiple hardware devices, and a baseboard Management Controller (BMC) in communication with the plurality of hardware devices. The BMC includes a first processor for executing a custom BMC firmware stack, and transmitting a watchdog message at an ongoing basis. The BMC also includes a second processor for receiving the watchdog message. When the watchdog message is received within a specified elapsed period of time, allow continued operation of the custom BMC firmware stack, and when not received within the specified elapsed period of time, place the BMC in a failsafe mode of operation.

摘要： Methods and systems for supporting similar thermal devices may involve collecting, by a thermal module on a management controller of an information handling system, device information about an add-in card, determining whether the add-in card was previously defined by matching the device against a table, searching the table based on the determination that the add-in card was not previously defined, determining whether the add-in card is supported by finding a match in the table, and applying a thermal tier associated with the match in the table based on the determination that the add-in card is supported. The device information collected may involve at least two of a reseller part number, description, device identifier, sub device identifier, vendor identifier, sub vendor identifier, slot identifier, lane width, and auxiliary power indicator. The search of the table may involve at least one of the description, lane width, and sub vendor identifier.

摘要： A controller may be configured to receive a wake-up message, the wake-up message including an address identifying a particular one of a plurality of information handling systems to be awakened from a non-awake state of the particular information handling system. The controller may also be configured to identify the particular information handling system based at least on the address included in the received wake-up message. The controller may further be configured to cause a host management controller of the particular information handling system to awaken from a non-awake state of the host management controller. The controller may also be configured to, after the host management controller of the particular information handling system has awakened, forward the wake-up message to the particular information handling system to cause the particular information handling system to awaken.
