Server Board S2600WP TPS
4.13.2
Features
NM provides feature support for policy management, monitoring and querying, alerts and
notifications, and an external interface protocol. The policy management features implement
specific IT goals that can be specified as policy directives for NM. Monitoring and querying
features enable tracking of power consumption. Alerts and notifications provide the foundation
for automation of power management in the data center management stack. The external
interface specifies the protocols that must be supported in this version of NM.
The role of BMC in Node Manager will include:
 External communication links
 Command passing through BMC
 Alerting
 BIOS-BMC-ME communication

Overview
The Intel
®
Server Platform Services (SPS) is a set of manageability services provided by the
firmware executing on an embedded ARC controller within the IOH. This management controller
is also commonly referred to as the Management Engine (ME). The functionality provided by the
SPS firmware is different from Intel
®
Active Management Technology (Intel
®
AMT or AT)
provided by the ME on client platforms.
Server Platform Services (SPS) are value-added platform management options that enhance
the value of Intel
®
platforms and their component ingredients (CPUs, chipsets, and I/O
components). Each service is designed to function independently wherever possible, or grouped
together with one or more features in flexible combinations to allow OEMs to
differentiate platforms.
4.14.2
BMC – Management Engine (ME) Distributed Model
The Intel
®
Server Board S2600WP covered in this specification will require Node Manager 2.0
(NM2.0) support.
The following management architecture would need to be supported on the
baseboard to meet product and validation requirements. The NM 2.0 functionality is provided by
the Intel
®
C600-A PCH Management Engine (ME).
The server management architecture is a partitioned model which places the Management
Engine, which is an embedded controller in the Intel
®
C600-A PCH, in between the BMC and
the processors. In this architecture, the PCH Management Engine is the owner of the PECI 3.0
bus and the ServerEngines* Pilot III BMC communicates with the ME through a SMBus*
connection (SMLINK 0.)
The ME provides PECI proxy support that allows the ServerEngines*
Pilot III BMC firmware to access processor functions available on the PECI bus.
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,
