Aspects disclosed in the detailed description include peripheral component interconnect express (PCIe) hosts adapted to support remote PCIe endpoints. In this regard, a PCIe host is configured to determine a temporal distance to an attached PCIe endpoint and compare the temporal distance to a predetermined threshold value. In one aspect, the PCIe host defines a first configuration parameter for the attached PCIe endpoint if the temporal distance is greater than the predetermined threshold value. In another aspect, the PCIe host defines a second configuration parameter different from the first configuration parameter for the attached PCIe endpoint if the temporal distance is less than or equal to the predetermined threshold value. By differentiating the attached PCIe endpoints based on temporal distances, the PCIe host can support compatibly a plurality of attached PCIe endpoints regardless of physical connection distances with the attached PCIe endpoints.
