Intel ® Server Board S2600CP and Intel ® Server System P4000CP Platform Management
The primary function of ME is to implement the NM 2.0 feature set. In this architectural model,
the ServerEngines* Pilot III BMC provides the external (LAN) interface to ME in the form of IPMI
bridging. A remote Node Manager application would establish a management session with the
ServerEngines* Pilot III BMC which in turn would bridge IPMI commands through the secondary
IPMB to the ME. In this scenario, the ServerEngines* Pilot III BMC simply acts as a proxy for
this communication pipe. The ME may also generate alerts to the ServerEngines* Pilot III BMC,
which may log these into the system SEL and/or output them to the remote application in the
form of IPMI LAN alerts.
The ServerEngines* Pilot III BMC needs access to various system registers in the processor
core silicon and integrated memory controller subsystem. Examples include Processor core and
Memory DIMMs temperature information. The ServerEngines* Pilot III BMC requires this
information as input into its fan speed control algorithms. The ServerEngines* Pilot III BMC
accesses these registers via the secondary IPMB bus connection to ME. Depending on the
particular data or register access needed, this is done using either the ME’s PECI proxy
functionality or through an abstracted data construct provided by the ME.
Also in this architecture, both the ServerEngines* Pilot III BMC and the ME are connected to the
system power supplies via a common PMBus (SMBUS physical) connection (SMLINK 1.) The
ME accesses the system power supplies in support of various NM 2.0 features. The
ServerEngines* Pilot III BMC monitors the power supplies in support of various power-related
telemetry and status information that is exposed as IPMI sensors.
