VPD data management system and method with redundancy and fault-tolerant capabilities

The invention belongs to the technical field of data management, and particularly provides a VPD data management system and method with redundancy and fault-tolerant capabilities, the system comprises a mainboard and a backboard, the mainboard is provided with a BMC, the backboard is provided with two EEPROMs, the two EEPROMs are in communication connection with the BMC through I2C links, and VPD data are stored in the EEPROMs; when the BMC is started, the VPD data of the two EEPROMs are read to a cache and verified, and when verification is passed, the VPD data of one EEPROM are selected and used for external interactive reading; when the VPD data are written, one EEPROM is selected, the calculated verification value and the VPD data are written into the EEPROM together, and after writing is completed, the VPD data are flashed to another EEPROM. And the content of the two EEPROMs is ensured to be correct normally. 本发明属于数据管理技术领域，具体提供一种具有冗余和容错能力VPD数据管理系统、方法，所述系统包括主板和背板，所述主板上设置有BMC，背板上设置有两个EEPROM，两个EEPROM分别通过I2
