Abstract: Systems and methods for using Peripheral Component Interconnect Express Vendor-Defined Message (PCIe-VDM) and Inter-Integrated Circuit (I2C) transport for network communications are described. In some embodiments, an IHS may include: a host processor; a Basic Input/Output System (BIOS) coupled to the host processor; a Baseboard Management Controller (BMC) coupled to the host processor; and a memory coupled to the BMC, the memory having program instructions stored thereon that, upon execution, cause the BMC to: receive a message over a network while the host processor is powered off, wherein the message originates from a remote IHS and targets the BMC; and in response to a pass-through data transfer rate available to the BMC not meeting a threshold value: power on the host processor; request that the BIOS boot up; and perform a communication with the remote IHS via a PCIe bus using a PCIe-VDM supported by the host processor.

Abstract: A storage controller failover system includes servers, storage controllers coupled to storage subsystems, and a switching system coupling the servers to the storage controllers. A storage controller configurations and storage controller caches for each of the storage controllers are stored in one or more database. A failure is detected of a first storage controller that has provided first storage communications along a first path between a first server and a first storage subsystem and, in response, a second storage controller that is configured to take over the first storage communications from the first storage controller is determined based on its second storage controller configuration. A first storage controller cache for the first storage controller is provided to the second storage controller, and the second storage controller is caused to provide the first storage communications along a second path between the first server and the first storage subsystem.

Abstract: In accordance with embodiments of the present disclosure, an information handling system may include a processor, an information handling resource communicatively coupled to the processor, and a management controller communicatively coupled to the processor and the information handling resource and configured to provide out-of-band management of the information handling system. The management controller may further configured to receive a message indicating that an existing private key associated with the information handling resource is compromised, the message including a replacement public key for replacing an existing public key associated with the information handling resource and associated with the existing private key and responsive to the message, cause the existing public key associated with the information handling resource to be replaced with the replacement public key.
