Minitype universal hardware platform architecture system for telecom and calculation, and reliability management method

Abstract

The invention provides a reliability management method used for a small telecom and calculation general hardware platform framework (MicroTCA) system; wherein, the MicroTCA system comprises at least a MicroTCA bearing management controller (MCMC), a main bearing board FRU information equipment and a standby bearing board FRU information equipment; the method comprises the steps as follows: when the main bearing board FRU information equipment is determined not in place or failure occurs, the FRU data of the standby bearing board FRU information equipment is used for configuration disposal. Meanwhile, the invention also discloses a MicroTCA system and a MicroTCA bearing management controller. In the embodiment of the invention, when the failure occurs to the bearing board FRU information equipment, complex main / standby conversion flow is not needed to be started, correct FRU data can be gained only by accessing the standby bearing board FRU information equipment, thus achieving the normal configuration and ,management on the system equipment.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a small general hardware platform architecture for telecommunications and computing (Micro Telecommunications Computing Architecture, MicroTCA) system and reliability management method. Background technique [0002] MicroTCA is a general-purpose hardware platform architecture for small telecommunications and computing developed by the PCI Industrial Computer Manufacturers Group (PICMG). MicroTCA uses Advanced Mezzanine Cards (AMC) to build systems. AMCs that support hot swapping can Plugs directly into the backplane of the MicroTCA. MicroTCA mainly targets low-end, cost-sensitive telecom or computing applications that require a small physical size. The main applications include wireless base stations, routers, media gateways, etc. The name of the basic MicroTCA specification is MicroTCA.0, which defines MicroTCA's chassis structure, management, power supply, heat...

AI Technical Summary

Problems solved by technology

If the MicroTCA system needs to work normally, MCH2 must start the active / standby switchover action, activate MCH2, and MCH2 will take over the work of MCH1. 2 The C bus accesses the FRU information device 2 of the carrier board to take over the management work, controls the normal power on and off of the AMC board and performs E-Keying management. This switching trigger increases the frequency and risk of active / standby switching

[0011] 2. The system has a long-term risk of faulty operation

[0012] To sum up, in the MicroTCA specification, the MCH and the FRU information equipment on the carrier board only pass through a dedicated I 2 C interface connection, therefore, can lead to the inconsistency of information synchronization of the FRU information equipment of the load board and the heavy burden of active-standby switchover in the load-carrying board FRU management bus architecture defined by the MicroTCA specification

Information synchronization failure will cause MCH to lose control of AMC management, and the system will not be able to configure and manage AMC normally

At the same time, the switching of the MCH depends on the quality of the corresponding carrier board FRU information equipment, which reduces the reliability of the system.
