Thermal Monitoring

The BMC provides monitoring of component and board temperature sensing devices. This
monitoring capability is instantiated in the form of IPMI analog/threshold or discrete sensors,
depending on the nature of the measurement.
For analog/threshold sensors, with the exception of Processor Temperature sensors, critical
and non-critical thresholds (upper and lower) are set through SDRs and event generation
enabled for both assertion and de-assertion events.
For discrete sensors, both assertion and de-assertion event generation are enabled.
Mandatory monitoring of platform thermal sensors includes:
Inlet temperature (physical sensor is typically on system front panel or HDD

backplane)
Board ambient thermal sensors

Processor temperature

Memory (DIMM) temperature

CPU VRD Hot monitoring

Power supply inlet temperature (only supported for PMBus*-compliant PSUs)

Additionally, the BMC firmware may create "virtual" sensors that are based on a combination
of aggregation of multiple physical thermal sensors and application of a mathematical formula
to thermal or power sensor readings.
9.3.10.1 Absolute Value versus Margin Sensors
Thermal monitoring sensors fall into three basic categories:
Absolute temperature sensors – These are analog/threshold sensors that provide a

value that corresponds to an absolute temperature value.
Thermal margin sensors – These are analog/threshold sensors that provide a value

that is relative to some reference value.
Thermal fault indication sensors – These are discrete sensors that indicate a specific

thermal fault condition.
9.3.10.2 Processor DTS-Spec Margin Sensor(s)
Intel ® Server Systems supporting the Intel
incorporate a DTS based thermal spec. This allows a much more accurate control of the
thermal solution and will enable lower fan speeds and lower fan power consumption. The
main usage of this sensor is as an input to the BMC's fan control algorithms. The BMC
implements this as a threshold sensor. There is one DTS sensor for each installed physical
processor package. Thresholds are not set and alert generation is not enabled for these
sensors.
