A multiple I/O interfacing system for a storage device and communicating method for the same are disclosed. The present invention is particularly embodied in the storage product of a computer system, where it implements a high-reliability connection between the processing units of at least two input/output cards. The preferred embodiment of the multiple I/O communicating method includes a first step of periodically broadcasting commands and data packets by the processing units for each I/O card. Simultaneously the processing units determine if any communication path fails. If there is no failed path, a first path is preferably being a master path, and a second path is being a secondary path. If one of the paths fails, the other one will be the communication path since a redundant mechanism activates. Next, the failure message will be sent to system unit the failure is eliminated.
