Abstract
A system and method for achieving peripheral component interconnect express (PCIe) redundancy and recovery are disclosed. In some embodiments, the system comprises an accelerated compute fabric (ACF) comprising a PCIe switch, an application host communicatively coupled to the ACF using one or more upstream PCIe links, and an endpoint device communicatively coupled to the ACF using one or more downstream PCIe links. The application host is configured to send PCIe transaction layer packets (TLP) addressed to the ghosted endpoint devices through the one or more upstream PCIe links, and the ACF is configured to redirect the PCIe TLP packets to the endpoint device through the one or more downstream PCIe links.
