Abstract
A data processing system is implemented with a backup PCI Express system, which is able to take over as the primary PCI Express system for ensuring that an endpoint device continues to function in a desired manner when a root complex in the primary PCI Express system is no longer functioning correctly or is deactivated for maintenance. The endpoint device is coupled to the primary root complex and a backup root complex through a multiplexer. When a failure or shutdown of the primary root complex is detected, the multiplexer is signaled to switch the communication of data from occurring between the primary root complex and the endpoint device to then occur between the backup root complex and the endpoint device. A PCI Express Link may be utilized to communicate such a failure or shutdown and/or to transfer information from the primary PCI Express system to the backup PCI Express system when the switch occurs.
