The Intel RMM3 is a 1.23-inch x 2.30-inch printed circuit board. When installed onto the Intel
RMM connector on Intel server boards, it provides an increased level of manageability over
basic server management available to the server board. Designed to work with the Integrated
Baseboard Management Controller (BMC), this small form-factor mezzanine card enables
graphical server control from anywhere, at anytime.
RMM3 has two variations – RMM3 Lite and RMM3 Lite-V, which have the same functionality as
RMM3. RMM3 Lite currently only can be used on Intel® S3420GPRX, it has not RMM3-
dedicated NIC. The management traffic only can go through onboard Integrated BMC-shared
NIC (NIC5 on Intel® S3420GPRX) and share network bandwidth with the host system. RMM3
Lite-V module currently only can be used on Intel® SR1640TH server system, its RMM3-
dedicated NIC is separated and integrated on server board.
