Справочник Пользователя для Intel Server Board S5500HCV S5500HCVR

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, and the system BIOS, and server management firmware. 
Figure 21 provides an illustration of the Server Management Bus (SMBUS) architecture as used 
on these server boards.  



  Baseboard management controller (BMC). 



  IPMI Watchdog timer. 



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



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



  Event receiver device: The BMC receives and processes events from other platform 

subsystems. 



  Field replaceable unit (FRU) inventory device functionality: The BMC supports access to 

system FRU devices using IPMI FRU commands. 



  System event log (SEL) device functionality: The BMC supports and provides access to 

a SEL. 



  Sensor data record (SDR) repository device functionality: The BMC supports storage 

and access of system SDRs. 



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

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



 IPMI 

interfaces: 

- 

Host interfaces include system management software (SMS) with receive message 
queue support and server management mode (SMM).  

- IPMB 

interface. 

- 

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



 Serial-over-LAN 

(SOL) 



  ACPI state synchronization: The BMC tracks ACPI state changes provided by the BIOS. 



  BMC Self-test: The BMC performs initialization and run-time self-tests, and makes 

results available to external entities.

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



  In-circuit BMC firmware update 



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