  • Patent number: 10437754
    Abstract: A management controller may request units of diagnostic information from a BIOS of the management controller's host computing device. The management controller may trigger an interrupt, in response to which the BIOS, by the execution of a processor of the host, may cause the diagnostic information to be copied to a video memory of the management controller. Upon the completion of the interrupt handler, a graphics controller of the management controller may cause the diagnostic information to be transferred to a non-volatile memory, and transferred out-of-band to a client device.

  • Patent number: 10346239
    Abstract: A system is described wherein power degradation can be used in conjunction with predictive failure analysis in order to accurately determine when a hardware component might fail. In one example, printed circuit boards (PCBs) can unexpectedly malfunction due to a variety of reasons including silicon power variation or air mover speed. Other hardware components can include silicon or an integrated circuit. In order to accurately monitor the hardware component, telemetry is used to automatically receive communications regarding measurements of data associated with the hardware component, such as power-related data or temperature data. The different temperature data can include junction temperature or ambient air temperature to determine an expected power usage. The actual power usage is then compared to the expected power usage to determine whether the hardware component can soon fail.

  • Patent number: 10303574
    Abstract: Self-generated thermal stress evaluation concepts are described. In one embodiment, a system includes a computing device, a cooling system, such as fans, that draws heat away from the computing device, and a management controller. The management controller can sense a temperature in the computing device and compare it against a temperature profile. The temperature profile can specify one or more target temperatures in the computing device over time. Based on the comparison, the management controller can adjust a cooling capacity of the cooling system. The adjustment to the cooling capacity can be achieved by reducing the speed of the fans, for example, to raise the temperature in the computing device. Processing tasks can also be executed in the computing device and, in response to the detection of an error in the computing device, the management controller can record the error and a profile for the error for further evaluation.

  • Patent number: 10261880
    Abstract: A smart add-in card can be leveraged to perform testing on a host server computer. The add-in card can include an embedded processor and memory. Tests can be downloaded to the add-in card to test a communication bus between the host server computer (motherboard) and the add-in card. In a particular example, a PCIe communication bus couples the motherboard to the add-in card and the tests can inject errors on the PCIe communication bus. The tests can be developed to test errors that are typically difficult to test without the use of special hardware. However, the smart add-in card can be a simple Network Interface Card (NIC) that resides on the host server computer during normal operation and is used for communication other than error testing. By using the NIC as a testing device, repeatable and reliable testing can be obtained.

  • Patent number: 10255151
    Abstract: A smart add-in card can be leveraged to perform testing on a host server computer. The add-in card can include an embedded processor and memory. Tests can be downloaded to the add-in card to test a protocol under which the add-in card operates. In a particular example, a PCIe communication bus couples the motherboard to the add-in card and the tests can purposely violate the PCIe specification. The tests can be developed to test conditions that are typically difficult to test without the use of special hardware. However, the smart add-in card can be a simple Network Interface Card (NIC) that resides on the host server computer during normal operation and is used for communication other than security testing. By using the NIC as a testing device, repeatable and reliable testing can be obtained.

  • Patent number: 9984021
    Abstract: Provided are systems and methods for a location-aware, self-configuring peripheral device. In some implementations, the peripheral device may include two or more personalities. In these implementations, a personality enables the peripheral device to provide a service. In some implementations, the peripheral device may be configured to receive a configuration cycle. In some implementations, the peripheral device may further select a personality from among two or more personalities. The peripheral device may use information derived from the configuration cycle to make this selection. Selecting a personality may further include configuring the peripheral device according to the selected personality.

  • Patent number: 9930051
    Abstract: In a cloud environment, each host computer can have its own security service processor with an independent network interface for communicating with a remote server over a network. The security service processor can provide remote management and security functionalities for various devices connected using different buses on a platform in each host computer. The security service processor can provide a centralized mechanism to verify and authenticate firmware updates for various devices using different buses. A hardware interface can allow the security service processor to provide remote debugging and diagnostic capabilities. The security service processor can also provide some of the typical functionalities of a baseboard management controller or can be used in addition to the baseboard management controller.

  • Patent number: 9807013
    Abstract: Techniques and solutions for automatically filtering network broadcast traffic are described. For example, network broadcast traffic can be automatically filtered by turning broadcast filtering on and off (e.g., as a continuous strobe pattern that alternates enabling and disabling of broadcast filtering). For example, a computing device (e.g., via a network interface or management controller of the computing device) can automatically enable network broadcast traffic filtering during a first time period (e.g., a four second time period) and disable network broadcast traffic filtering during a second time period (e.g., a one second time period). A computing device can also automatically enable and disable network broadcast traffic filtering according to an on-off pattern (e.g., based on various criteria, such as network queue size, broadcast traffic volume, etc.).
