BMC System Management Health Monitoring

The BMC tracks the health of each of its IPMI sensors and report failures by providing a "BMC
FW Health" sensor of the IPMI 2.0 sensor type Management Subsystem Health with support for
the Sensor Failure offset. Only assertions should be logged into the SEL for the Sensor Failure
offset. The sensor number of the failed sensor is provided in event data byte 2, as per the IPMI
2.0 Specification. The BMC Firmware Health sensor asserts for any sensor when 10
consecutive sensor errors are read. These are not standard sensor events (that is, threshold
crossings or discrete assertions). These are BMC Hardware Access Layer (HAL) errors like I2C
NAKs or internal errors while attempting to read a register. If a successful sensor read is
completed, the counter resets to zero.

Processor Sensors

The BMC provides IPMI sensors for processors and associated components, such as voltage
regulators and fans. The sensors are implemented on a per-processor basis.

Thermal and Acoustic Management

This feature refers to enhanced fan management to keep the system optimally cooled while
reducing the amount of noise generated by the system fans. Aggressive acoustics standards
might require a trade-off between fan speed and system performance parameters that
contribute to the cooling requirements, primarily memory bandwidth. The BIOS, BMC, and
SDRs work together to provide control over how this trade-off is determined.
This capability requires the BMC to access temperature sensors on the individual memory
DIMMs. Additionally, closed-loop thermal throttling is only supported with buffered DIMMs.
