Intelligent Platform Management Interface (IPMI)

BY: DEREK WUNG

Outline Background information Objective System Design

Background Information What is IPMI?

History of IPMI

Advantages of using IPMI

IPMI is Composed of Software

• IPMIview

Hardware

Objective:Create system that implements IPMI

for standalone electronics chassis

Baseboard Management Controller (BMC)

Heart of IPMI Helps elements

communicate with one another

I2C- 2 lines: Clock (SCL) & Data (SDA)

SCL Traffic Lights SDA Roads

BMC: Renesas H8S/2167

144 pins

12 pins for I2C (6 ports)

3 ports for transmitting/receiving data

Non-Volatile Storage: Phillips PCF8582C-2

Preserves information when power is off

I2C-compatible Ten-year data

storage

Sensors

Remote Management Card: MegaRAC G4

IPMI V 2.0 Directly connect

to BMC

Interfaces for IPMI Messaging
