5.1Sahalee Baseboard Management Controller (BMC)

The Sahalee Baseboard Management Controller (BMC) contains a 32-bit RISC processor and associated peripherals used to monitor the system for critical events. The Sahalee BMC is designed to be the central server management controller in an enterprise server system and is common to several Intel® Architecture 32-bit-based and Intel Itanium™ Processor-based platform implementations. The Sahalee BMC contains the logic needed for executing the firmware, controlling the system, monitoring sensors, and communicating with other systems and devices via various external interfaces.

The Sahalee BMC resides on an Intel® Management Module (IMM) that mounts onto the Intel® Server Board Set SE8500HW4 Mainboard. Either an IMM Professional or IMM Advanced is required to boot and use the Intel® Server Board Set SE8500HW4. See the Intel® Management Module Installation and User’s Guide for a description of these parts.

Figure 8 shows the I2C block diagram for Intel® Server Board Set SE8500HW4 and both the Intel® Server Platform SR4850HW4 and Intel® Server Platform SR6850HW4.
