Abstract: Embodiments are described for recovery, via a sideband management bus, of firmware of a device such as an FPGA (Field Programmable Gate Array) card installed within an IHS (Information Handling System). A remote access controller of the IHS generates a security key for the device and transmits it to the device. The remote access controller requests the device to report the current version of the firmware in use by the device. The response from the device is authenticated based on the security key. If the current firmware version reported by the device is consistent with the master firmware version, the device is halted and the current firmware of the device is replaced with the master firmware. The device is initialized based on the master firmware used to update the device firmware.

Abstract: Methods, systems, and computer programs encoded on computer storage medium, for receiving a request to switch a mode of an information handling system (IHS) from a multi-socket mode to a multi-single socket mode; in response to receiving the request, placing each socket of the IHS in an auxiliary power state independent of each other; after placing each socket of the IHS in the auxiliary power state, altering parameters of the sockets of the IHS, including: altering CPU straps, power sequencing, reset sequencing, and bus re-direction associated with one or more of the sockets of the IHS; and in response to altering the parameters of the sockets of the IHS, switching the mode of the IHS from the multi-socket mode to the multi-single socket mode such that a processor for each socket is a bootstrap processor.

Abstract: Embodiments are described for supporting remote monitoring and management of FPGA (Field Programmable Gate Array) card operations. The FPGA card includes an external interface supporting core operations of the FPGA and for accessing functions defined by the programmable logic of the FPGA. Network activity data is collected from a network controller of the FPGA card. In response to invocation of an internal operations interface function by an external interface request, the collected network activity data is included in a network report for transmission to a remote access controller. A proxy message compliant with the external interface is used to transport the collected network activity data that is not supported by the external interface. The proxy message is transmitted to an FPGA management controller via the external interface, where it is converted to remote management protocol and transmitted to the remote management controller.

Abstract: Systems and methods are disclosed for securing an information handling system. A method for securing an information handling system may include securing the information handling system in an enclosure with a locking mechanism of a bezel; receiving a request to unlock the bezel at a baseboard management controller (BMC), the BMC communicatively coupled to the bezel; retrieving a first artifact stored in a trusted platform module (TPM) in response to the request; attempting to authorize the request using the first artifact; and unlocking the locking mechanism if the request is authorized.

Abstract: In accordance with embodiments of the present disclosure, a management controller configured to provide management-domain management of an information handling system may include a processor and a key management utility embodied in non-transitory computer-readable media. The key management utility may be configured to issue one or more commands to a cryptoprocessor for storing and sealing a key encryption key on the cryptoprocessor, wherein the key encryption key is for decrypting a media encryption key for encrypting and decrypting data stored to a storage resource of a host domain of the information handling system. The key management utility may also be configured to issue one or more commands to the cryptoprocessor for unsealing and retrieving the key encryption key from the cryptoprocessor.

Abstract: Embodiments are described for securing access to a debug port of an FPGA (Field Programmable Gate Array) card installed within an IHS (Information Handling System). A remote access controller determines the status of the FPGA card debug port via a query to a management controller of the FPGA card. The remote access controller generates a passcode for the debug port and disables the debug port via a message to the management controller. The management controller detects a request, that includes a requestor password, for access to the debug port. The remote access controller authorizes the requestor's access to the debug port if the requestor password matches the generated passcode. The remote access controller disables the debug port upon each power cycle of the FPGA card or upon detecting removal of a device from the debug port.

Abstract: A method may include in response to determining a host system is off, configuring a video controller of an information handling system including setting a display resolution of the video controller and writing management video data associated to a primary frame buffer such that management video data is able to be retrieved by the video controller for output to one or both of a first display associated with the host system and a second display of a management interface communicatively coupled to a management controller communicatively coupled to the processor and the memory and configured to provide out-of-band management of the information handling system. The method may further include in response to determining the host system is on, writing the management video data to an alternate frame buffer such that management video data is able to be retrieved by the video controller for output to the second display.
