Abstract

The invention discloses a multi-main-control-panel redundant backup system based on a PCIe bus. The system comprises a main board circuit A (12), a main board circuit B (13), a main board circuit C (14), a PCIe switching circuit (15), an FC channel card circuit (10) and a PCIeRaid card circuit (11). After the system is powered on, a test computer transmits an initial configuration file into a PCIe management chip (7), and then the PCIe management chip (7) writes the initial configuration file into a serial EEPROM (8) in a programming mode. After programming writing is completed, the system is restarted, and the PCIe management chip (7) reads the initial configuration file in the serial EEPROM (8) through an SMBus for the purpose of configuring a port register of the PCIe management chip (7), a partition pattern and a clock pattern. The multi-main-control-panel redundant backup system achieves real-time switching in a failure, and the real-time performance of the system is improved.

Description

[0001] technical field [0002] The invention relates to a redundant backup system of multiple main control boards, in particular to a redundant backup system of multiple main control boards based on PCIe bus. Background technique [0003] The redundant backup system of multiple main control boards is mainly used for high-safety and high-reliability system applications. When the system is abnormal, it can perform fault location and backup system switching. The previous multi-master board redundant backup system includes: main board, PCI peripheral board, board status monitoring system, I2C controller, CPU processor and BMC controller. The board status monitoring system is used to collect the voltage, current and temperature signals on the board to detect whether the system is running normally. However, the previous redundant backup system with multiple main control boards is a fault-tolerant computer based on the CPCI bus. When the backup system is switched, the computer sy...
