Abstract

An information handling system includes a peripheral component interconnect express root complex, a basic input output system, and a root complex mirroring block. The peripheral component interconnect express root complex includes a plurality of peripheral component interconnect express ports. The basic input output system is in communication with the peripheral component interconnect express root complex, and is configured to detect a peripheral component interconnect express adaptor configuration, and to set a peripheral component interconnect express mirroring setting based on the peripheral component interconnect express adaptor configuration. The root complex mirroring block is in communication with the basic input output system, and is configured to mirror data between a first peripheral component interconnect express adaptor and a second peripheral component interconnect express adaptor based on the peripheral component interconnect express mirroring setting.
