SMBus Interface
ConnectX®-6 Lx technology maintains support for manageability through a BMC.
ConnectX®-6 Lx OCP 3.0 adapter can be connected to a BMC using MCTP over SMBus or
MCTP over PCIe protocols as if it is a standard NVIDIA OCP 3.0 adapter. For configuring
the adapter for the specific manageability solution in use by the server, please contact
NVIDIA Support.
