Abstract
A system, method and storage medium for providing redundant I/O access between a plurality of interconnected processor nodes and I/O resources. The method includes determining whether a primary path between the interconnected processor nodes and the I/O resources is operational, where the primary path includes a first processor node and a primary multiplexer. If the primary path is operational, the transactions are routed via the primary path. If the primary path is not operational, the transactions are routed between the interconnected processor nodes and the I/O resources via an alternate path that includes a second processor node and an alternate multiplexer.
