Question My X12DDW-A6, X12DPI-N and X12SPW-F systems all have Host Interface in BMC settings.  What is for?  What happen if I disabled it? Answer Host interface is a new BMC in-band communication protocol that was introduced in Supermicro X12 and H12 motherboards.  It is using http secure connection to communicate between the host system and BMC internally through USB port.  If you disabled the host interface, the system will be revert to KCS  for communication between host and BMC.
