Providing system inventory data from a firmware to a baseboard management controller using an OEM-defined uniform resource identifier
A firmware driver generates a REST Hypertext Transfer Protocol (“HTTP”) request to an original equipment manufacturer (“OEM”)-defined uniform resource identifier (“URI”) for combined inventory data to an interface exposed by a baseboard management controller (“BMC”). The firmware driver receives the combined inventory data from the BMC in response to the request to the OEM-defined URI exposed by the BMC. The firmware driver performs an inventory of the managed computing system to obtain updated inventory data and determines if the updated inventory data and the combined inventory data are identical. If the updated inventory data and the combined inventory data are not identical, the firmware driver generates new combined inventory data for the managed computing system and posts (e.g., by way of a call to an HTTP POST method) the new combined inventory data for the managed computing system to the OEM-defined URI exposed by the BMC.
