22. Baseboard Management Controller (BMC)
22.1 Feature Support
22.1.1 IPMI 2.0 Features
x Baseboard management controller (BMC).
x IPMI Watchdog timer.
x Messaging support, including command bridging and user/session support.
x Chassis device functionality, including power/reset control and BIOS boot flags support.
x Event receiver device: The BMC receives and processes events from other platform subsystems.
x Field replaceable unit (FRU) inventory device functionality: The BMC supports access to system FRU devices
using IPMI FRU commands.
x System event log (SEL) device functionality: The BMC supports and provides access to a SEL.
x Sensor device record (SDR) repository device functionality: The BMC supports storage and access of system
SDRs.
x Sensor device and sensor scanning/monitoring: The BMC provides IPMI management of sensors. It polls sensors
to monitor and report system health.
x IPMI interfaces.
x Host interfaces include system management software (SMS) with receive message queue support, and server
management mode (SMM).
x Terminal mode serial interface.
x IPMB interface.
x LAN interface that supports the IPMI-over-LAN protocol (RMCP, RMCP+).
x Serial-over-LAN (SOL).
x ACPI state synchronization: The BMC tracks ACPI state changes that are provided by the BIOS.
x BMC self test: The BMC performs initialization and run-time self-tests, and makes results available to external
entities.
