Abstract: Methods and systems for power management are disclosed. The disclosed power management method and systems may improve the likelihood of data processing systems providing desired computer implemented services while meeting power budget goals and/or other types of goals regarding power consumption, use, and/or provisioning. To improve the likelihood of the power budgets being met, the system may dynamically update power allocations to various components of data processing systems. The power allocations may be dynamically allocated by predicting how changes in existing power allocations may impact the ability of the data processing system to service power allocation requests. If it appears that changes in one or more existing power allocations may allow a power allocation request to be serviced, then the power allocations may be dynamically reallocated to free allocable power. The freed allocable power may be used to service the power allocation.

Abstract: 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.

Abstract: 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.

Abstract: 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.
Abstract translation: 控制器可以被配置为接收唤醒消息，该唤醒消息包括标识要从特定信息处理系统的非清醒状态唤醒的多个信息处理系统中的特定一个的地址。 控制器还可以被配置为至少基于接收到的唤醒消息中包括的地址来识别特定信息处理系统。 控制器还可以被配置为使特定信息处理系统的主机管理控制器从主机管理控制器的非唤醒状态唤醒。 控制器还可以被配置为在特定信息处理系统的主机管理控制器已经唤醒之后，将唤醒消息转发到特定信息处理系统以使特定信息处理系统唤醒。

Abstract: Embodiments of the present disclosure provide systems and methods to provide dynamic participation of multiple services to generate an overall health score in a Desktop Bus (D-Bus) platform. According to one embodiment, an Information Handling System (IHS) includes multiple hardware devices that are managed by a plurality of D-Bus objects that communicate among one another using a D-Bus in which the D-Bus objects are arranged in a hierarchy of parent-child relationships. The IHS also includes computer-executable code to cause each of the D-Bus objects to receive a request for a health score of one of one of the hardware devices that it manages using one or more child objects that interact with the one hardware device, generate an intermediate health score using measurements obtained by its child objects, and send the intermediate health score to its parent object.

Abstract: 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.
