Intel® Server System SR1640TH TPS 

Functional Architecture 

Revision 1.0 

 

 

21 

Intel order number: E94847-001 

The platform management subsystem is based on the Integrated BMC features of the 
ServerEngines* Pilot II. The onboard platform management subsystem consists of 
communication buses, sensors, system BIOS, and server management firmware. The 
following diagram provides an overview of the Server Management Bus (SMBUS) 
architecture used on this server board.  

ƒ

  Integrated Baseboard Management Controller (Integrated BMC). 

ƒ

  IPMI Watchdog timer. 

ƒ

  Messaging support, including command bridging and user/session support. 

ƒ

  Chassis device functionality, including power/reset control and BIOS boot flags 

support. 

ƒ

  Event receiver device: The Integrated BMC receives and processes events from 

other platform subsystems. 

ƒ

  Field replaceable unit (FRU) inventory device functionality: The Integrated BMC 

supports access to system FRU devices using IPMI FRU commands. 

ƒ

  System event log (SEL) device functionality: The Integrated BMC supports and 

provides access to a SEL. 

ƒ

  Sensor device record (SDR) repository device functionality: The Integrated BMC 

supports storage and access of system SDRs. 

ƒ

  Sensor device and sensor scanning/monitoring: The Integrated BMC provides IPMI 

management of sensors. It polls sensors to monitor and report system health. 

ƒ

 IPMI 

interfaces. 

o  Host interfaces include system management software (SMS) with receive 

message queue support and server management mode (SMM). 
o  Terminal mode serial interface 
o IPMB 

interface 

o  LAN interface that supports the IPMI-over-LAN protocol (RMCP, RMCP+) 

ƒ

 Serial-over-LAN 

(SOL) 

ƒ

  ACPI state synchronization: The Integrated BMC tracks ACPI state changes provided 

by the BIOS. 

ƒ

  Integrated Baseboard Management Controller (Integrated BMC) self test: The 

Integrated BMC performs initialization and run-time self tests, and makes results 
available to external entities. 

 
For more information, refer to the IPMI 2.0 Specification. 

The Integrated BMC supports the following non-IPMI features. This list does not preclude 
support for future enhancements or additions. 

ƒ

  In-circuit Integrated BMC firmware update. 

ƒ

  Fault resilient booting (FRB): FRB2 is supported by the watchdog timer functionality 

ƒ

  Chassis intrusion detection and chassis intrusion cable presence detection. 

ƒ

  Basic fan control using TControl version 2 SDRs. 

ƒ

  Acoustic management: Support for multiple fan profiles. 

ƒ

  Signal testing support: The Integrated Baseboard Management Controller (Integrated 

BMC) provides test commands for setting and getting platform signal states.
