Problems solved by technology

[0006] The IPMB dual-bus connection method has the following disadvantages: if the I2C signal of any IPMC or BMC node has a hardware signal abnormality (SCL or SDA is always low), it will clamp the entire I2C bus (normal data transmission and reception cannot be performed), causing all IPMC Nodes cannot communicate through the I2C bus signal; in addition, the location of the I2C faulty single board cannot be located
This centralized data management method cannot control the equipment environment in a timely manner, especially when the number of managed slots increases and the amount of data increases sharply, the feedback delay of chassis information is even more serious
At the same time, when the hardware of the communicating IPMC node fails, it will still clamp the I2C bus, causing the BMC to lose control of the bus

Abstract

A distributed intelligent platform management bus (IPMB) connection method and ATCA frame. The ATCA frame having a plurality of slots is provided with ATCA boards inserted into the slots. Each ATCA board comprises two main control boards and at least one node board, each node board being provided with an IPMC thereon; a BMC is integrated on the two main control boards respectively, and an IPMI is disposed on each main control board; the BMC on each main control board is in a point-to-point star connection with the IPMC on each node board and the IPMI on the other main control board; the BMC exchanges data with the IPMC node of a peripheral board via the IPMI; the BMC exchanges data with the IPMI via the local bus, and the IPMI exchanges data with each IPMC node of the peripheral board via independently distributed I2C-based multipath IPMB buses, the total number of the I2C-based multipath IPMB buses provided by the IPMI corresponding to the number of the peripheral boards.

Description

technical field [0001] The invention relates to the field of computers, in particular to a distributed intelligent platform management bus (Intelligent Platform Management BUS, IPMB for short) connection method and an ATCA machine frame. Background technique [0002] The Advanced Telecom Computing Architecture (ATCA) standard originated from the CompactPCI standard, a new generation of mainstream industrial computing technology widely used in telecommunications, aerospace, industrial control, medical equipment, intelligent transportation, military equipment and other fields. It is a cost-effective, modular-based, compatible, and scalable hardware architecture for next-generation converged communications and data network applications. [0003] The Intelligent Platform Management Interface (IPMI for short) was originally an industrial standard adopted by peripheral devices of an enterprise system with an Internet (Intel) architecture. like figure 1 As shown, in the ATCA chas...
