mBMC
The mini Baseboard Management Controller (mBMC) is an Application Specific Integrated
Circuit (ASIC) with many peripheral devices embedded into it. The mBMC contains the logic
needed for controlling the system, monitoring the sensors, and communicating with other
systems and devices via various external interfaces.
The following figure is a block diagram of the mBMC as it is used in a server management
system. The external interface blocks to the mBMC are the discrete hardware peripheral device
interface modules.
