II2 IPMI v2.0

This course covers Intelligent Platform Management Interface version 2

formateur
Objectifs
  • Explaining the functional units used in an IPMI system (BMC, SDR, SEL, PEF, etc.).
  • Understanding the bus protocols on which IPMI messages are transferred : I2C, IPMB, SMbus.
  • Clarifying the chassis management based on ICMB protocol.
  • Sending alerts through LAN or serial/modem interfaces.
  • Explaining the parameterizing of message channels.
  • Studying the IPMI commands through sequences.
  • Detailing how system software and BMC embedded software interact.

  • This course has been delivered several times to companies developing complex processing systems.
A more detailed course description is available on request at training@ac6-training.com
Prerequisites
  • Experience of a 32-bit processor, such as NXP ColdFire or AMCC 4XX microcontrollers.
  • Knowledge of Ethernet is recommended, see our course reference cours N1 - Ethernet and switching
