ABSTRACT:
The present invention is directed to a system and method of providing an embedded input/output interface failover. An apparatus for providing an input/output interface with failover functionality between a host and a target may include a first data transfer route suitable for communicatively coupling the apparatus to a host system, a second data transfer route suitable for communicatively coupling the apparatus to a target, and a third data transfer route suitable for communicatively coupling the apparatus to the target. A memory suitable for storing electronic data is also included, the memory including a program of instructions. A controller is communicatively coupled to the first data transfer route, the second data transfer route, the third data transfer route and the memory. The controller is suitable for performing the program of instructions, wherein the program of instructions configures the controller to transfer data between the host and target utilizing the third data transfer route should the second data transfer route become unavailable.
