Abstract

The invention is applied in the field of computers, and provides an intelligent platform management interface (IPMI) message transmission device, an IPMI message transmission system and computer equipment. The IPMI message transmission device comprises an intelligent platform management bus (IPMB) message receiving and processing task unit, an IPMB message receiving interface, an IPMB message transmitting interface and an IPMB message transmitting and response waiting interface, wherein the IPMB message receiving and processing task unit is used for acquiring message from an IPMB message buffer queue, performing response message matching if the acquired message is response message, and putting the request message into an IPMB request message queue if the acquired message is request message; the IPMB message receiving interface is used for reading the message in the IPMB request message queue; the IPMB message transmitting interface is used for transmitting the verification passing IPMI message by the drive of an I2C bus; and the IPMB message transmitting and response waiting interface is used for calling the IPMI request message transmitted by the IPMB message transmitting interface and acquiring the corresponding response message acquired by the IPMB message receiving and processing task unit. The device and the system provide connection guarantee for construction of an IPMI management network.

Description

technical field [0001] The invention belongs to the field of computers, and in particular relates to an IPMI message transmission device, a system and computer equipment. Background technique [0002] In the Intelligent Platform Management Interface (Intelligent Platform Management Interface, IPMI) specification, it is supported to expand the platform management function of the system by adding additional management controllers. Communication between these management controllers is achieved through an intelligent platform management bus (Intelligent Platform Management Bus, IPMB). IPMB bus is based on I 2 C serial bus, intelligent and non-intelligent I can be mounted on the IPMB bus 2 C equipment. [0003] The Intelligent Platform Management Bus Communications Protocol Specification v1.0 defines a byte-level transmission protocol for IPMI message packets between intelligent devices. 2 The C physical interfaces together form the IPMB bus. [0004] The IPMB bus uses a req...
