Abstract
A method of data synchronization is to be implemented by a redundant server system including an active input/output module (IOM) and a passive IOM. The method includes: allocating a primary transfer buffer in the active IOM; allocating a secondary transfer buffer in the passive IOM; collecting pieces of secondary dedicated-sensor data, and storing the pieces of secondary dedicated-sensor data in the primary transfer buffer at once; collecting pieces of primary dedicated-sensor data; after the pieces of primary dedicated-sensor data have been collected, updating the primary state data based on the pieces of primary dedicated-sensor data thus collected and the pieces of secondary dedicated-sensor data stored in the primary transfer buffer at once, and storing the primary state data thus updated in the secondary transfer buffer; and updating the secondary state data based on the primary state data that have been updated and that are stored in the secondary transfer buffer.
