which specific platform targets are configured, which in turn determines how the system fans
operate to meet those targets. Platform profile targets are determined by the type of platform
that is selected when running the FRUSDR utility.
4.6 Standard Fan Management
The Integrated BMC controls and monitors the system fans. For each fan, there is a fan speed
sensor that provides fan failure detection. Some systems also provide fan presence detection in
which the Integrated BMC maps into per-fan presence sensors.
It is possible for the Integrated BMC to control the speed of some fans. Controllable fans are
divided into fan domains in which there is a separate fan speed control for each domain and a
separate fan control policy configurable for each domain. Two or more fans tied to a common
fan domain cannot be controlled independently. For the Intel
®
Server Board S5400SF, there are
four fan domains, which control four system fan connectors and two CPU fan connectors. The
following table identifies the association of the on-board fan connectors to a specific fan domain.

A fan domain can have a set of temperature and fan sensors associated with it. These are used
to determine the current fan domain state. A fan domain has three states: sleep, nominal, and
boost. The sleep and boost states have fixed but configurable (via OEM SDRs) fan speeds
associated with them. The nominal state has a variable speed determined by the fan domain
policy. An OEM SDR record is used to configure the fan domain policy.
Fan domain state is controlled by several factors (states in order of precedence, high to low):
Boost
Associated fan in a critical or non-recoverable state (non-redundant fan configuration).
Fan domain is in an insufficient resources redundancy state (redundant fan
configuration).
Any temperature sensor in a critical or non-recoverable state, with the exception of
Processor Thermal Control Monitoring sensor (ProcHot) or VRD Over-Temperature
(VRDHot) sensor.
