The card satellite controller (SC) provides independent supervisory and card management functions including power and temperature monitoring. The host server board management controller (BMC) can interact with the satellite controller to monitor and control the card through out-of-band communication. The card supports the PLDM protocol over MCTP over SMBUS, complying with DMTF standards. Refer to the Alveo Card Out-of-Band Management Specification for Server BMC (XD038) for more information.
