System and method for fail-over data transport

摘要

A system and method for maintaining a communications within a computer system after a data transport failure across a first link. Fail-over capability is attained by re-establishing communications across a secondary link using different transport mechanisms. Between two Input/Output Processors (IOPs) within a computer system, such as a server, a series of data transactions therebetween are queued until transaction completion. Upon detection of a failure condition between the IOPs across the first link, the IOPs engage fail-over mechanisms to preserve uncompleted data transactions until communications are re-established across the secondary link.
