LVC21F-314 Standardizing the Arm servers side-band management interface

Session Abstract

Level: Advanced The Arm Server Base Manageability Requirements (SBMR) Specification defines standard firmware and hardware management interfaces for Arm servers. The SBMR "side-band" interface is used for communicating power sensors, telemetry data, and RAS and other events from the Arm server CPUs to the BMC. The data is then made available to remote management software through interfaces such as Redfish and IPMI. In this presentation, we will highlight the design and requirements of the Arm servers side-band management interface. We will also showcase proof-of-concept porotype of the interface using the OpenBMC firmware and Zephyr open source projects running on ASPEED AST2600 evaluation kit and Arduino Due microcontroller board. Finally, we will present upstreaming and enabling activity around this prototype.
