Figure 21. External Interfaces to mBMC
5.3 mBMC Hardware Architecture
The following figure shows an example of the internal functional modules of the mBMC in a
block diagram. The mBMC controls various server management functions, such as the system
power/reset control, a variety of types of sensor monitoring, system initialization, fault resilient
booting (FRB).
The memory subsystem consists of flash memory to hold the mBMC operation code, firmware
update code, System Event Log (SEL), Sensor Data Record (SDR) repository, and mBMC
persistent data.
A private SMBus provides the mBMC with access to various sensors located in the server
system.
