US Patent 10521376 Enclosure management over PCIE

An apparatus may include a baseboard management controller (BMC) configured to monitor one or more statuses of a storage array enclosure of the BMC. The BMC may further communicate with a host device of a PCIe network topology via a PCIe port of the BMC including performing a direct memory access (DMA) write to store status information of the enclosure to a memory of the host device via the PCIe network topology and performing a DMA read to retrieve control information from the memory of the host device via the PCIe network topology. In addition, the BMC may control one or more devices of the storage array enclosure based on the retrieved control information.
