Rest over IPMI interface for firmware to BMC communication
Technologies are described herein for a representational state transfer (“REST” or “RESTful”) over an Intelligent Platform Management Interface (“IPMI”) interface for firmware to a baseboard management controller (“BMC”) communication and applications thereof. These applications include, but are not limited to, remote firmware configuration, firmware updates, peripheral device firmware updates, provision of management information such as system inventory data, cloning and batch migration of firmware configuration settings, and firmware integrity monitoring. This functionality can be provided in a way that enables communication between BMCs and firmware to utilize modern manageability interfaces while maintaining backward compatibility with previous IPMI implementations.
1. A computer-implemented method, comprising:
executing a first driver in a firmware of a computing system to:
obtain management data for the computing system, and

11. The non-transitory computer-readable storage medium of claim 10 , wherein the management server is configured to:
receive the REST HTTP request comprising the management data from the IPMI agent;
store the management data; and
receive and respond to a request received from a management client for the management data.
12. The non-transitory computer-readable storage medium of claim 11 , wherein the management server is further configured to:
generate a REST HTTP response to the REST HTTP request; and
provide the REST HTTP response to an interface exposed by the IPMI agent.

receive a REST HTTP response from the management server;
generate an OEM IPMI response comprising the REST HTTP response; and
provide the OEM IPMI response comprising the REST HTTP response to the second driver.
14. The non-transitory computer-readable storage medium of claim 13 , wherein the second driver is further configured to:
receive the OEM IPMI response comprising the REST HTTP response from the IPMI agent;
retrieve the REST HTTP response from the OEM IPMI response received from the IPMI agent; and
provide the REST HTTP response to an interface exposed by the first driver.
15. The non-transitory computer-readable storage medium of claim 9 , wherein the management data is expressed using a JavaScript Object Notation (JSON) format based on an Open Data Protocol (OData).
16. The non-transitory computer-readable storage medium of claim 9 , wherein the management data is obtained at a boot time of the computing system.
17. A computing system, comprising:
one or more processors;
a baseboard management controller (BMC); and
at least one non-transitory computer-readable storage medium having computer-executable instructions stored thereupon which, when executed by the one or more processors, cause the computing system to:
execute a first driver in a firmware of the computing system to:
