The OpenBMC project is a Linux Foundation collaborative open-source project whose goal is to produce an open source implementation of the Baseboard Management Controllers (BMC) Firmware Stack.[1][2][3] OpenBMC is a Linux distribution for BMCs meant to work across heterogeneous systems that include enterprise, high-performance computing (HPC), telecommunications, and cloud-scale data centers.[3][4]


OpenBMC traces its origin to 2014, when four Facebook engineers at a Facebook hackathon event created the prototype version.[5] Founding organizations of the OpenBMC project are Microsoft, Intel, IBM, Google, and Facebook.[6][3]


OpenBMC uses the Yocto Project as the underlying building and distribution generation framework.[7] OpenBMC uses D-Bus as an inter-process communication (IPC).[8][9] OpenBMC includes a web application for interacting with the firmware stack.[10]


Google/Rackspace partnership
Barreleye G2 / Zaius—two-socket server platform using POWER9 processors.[11][12]
Power Systems AC922 also "Witherspoon" or "Newell"—two-socket, 2U Accelerated Computing (AC) node using POWER9 processors with up to 6 Nvidia Volta GPUs.[13][14] AC922 was used in the U.S. Department of Energy's Sierra and Summit supercomputers.[15][16]
Raptor Computing Systems / Raptor Engineering
Talos II—two-socket workstation and development platform; available as 4U server, tower, or EATX mainboard.[17][18]


u-bmc is a project which is developed parallel to OpenBMC but uses gRPC instead of IPMI.[19]
