Intelligent Platform Management Interface Spec, v.2, Rev. 1.1
This document presents the base specifications for the Intelligent Platform Management Interface (IPMI) architecture. The IPMI specifications define standardized, abstracted interfaces to the platform management subsystem. IPMI includes the definition of interfaces for extending platform management between board within the main chassis, and between multiple chassis.
The term “platform management” is used to refer to the monitoring and control functions that are built in to the platform hardware and primarily used for the purpose of monitoring the health of the system hardware. This typically includes monitoring elements such as system temperatures, voltages, fans, power supplies, bus errors, system physical security, and more. It includes automatic and manually driven recovery capabilities such as local or remote system resets and power on/off operations. It includes the logging of abnormal or ‘out-of-range’ conditions for later examination and alerting where the platform issues the alert without aid of run-time software. Lastly it includes inventory information that can help identify a failed hardware unit.
This document is the main specification for IPMI. It defines the overall architecture, common commands, event formats, data records, and capabilities used across IPMI-based systems and peripheral chassis. This includes the specifications for IPMI management via LAN, serial/modem, PCI Management bus, and the local interface to the platform management.
