QSSC-S4R Technical Product Specification Main Board Server Management

3. Main Board Server Management

3.1 Introduction

The QSSC-S4R Server Management consists of many embedded technologies. These technologies are a combination

of the following:

x Board instrumentation

x Sensors

x Interconnects

x Server management controllers

x Firmware algorithms

x System BIOS

The QSSC-S4R board set platform management system is based on the IPMI 2.0 Specification. The system includes

the following major elements:

x Baseboard Management Controller (BMC) with RTC access

x IPMI messaging, commands, and abstractions

x Sensors for status, voltage, temperature and fan speed

x Sensor Data Records (SDRs) and SDR repository

x Field Replaceable Unit (FRU) information and System Globally Unique ID (GUID)

x Autonomous event logging

x System Event Log (SEL) [3639 events]

x BMC watchdog timer, covering the BIOS and run-time software

x IPMI channels, sessions, and users

x Serial/modem paging

x Serial/modem/LAN alerting using the Platform Event Trap (PET) format

x DPC (Direct Platform Control): IPMI messaging over LAN (available via onboard network controllers)

x Platform Event Filtering (PEF)

x IPMI terminal mode support

x BIOS logging of POST progress and POST errors

x Integration with the BIOS console redirection via IPMI v2.0 serial port sharing

x Serial Over LAN (SOL 2.0) support

3.1.1 IPMI 2.0 Features

x Baseboard management controller (BMC).

x IPMI Watchdog timer.

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

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

x Alert processing device including platform event trap (PET) and Simple Network Management Protocol (SNMP)

alerts via LAN interfaces.

x Platform event filtering (PEF) device.

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

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

using IPMI FRU commands.
