Claim 11:
12. A method for extending a peripheral component interconnect express (PCIe) fabric, comprising:
enumerating, by a host root complex of a host PCIe fabric, endpoints of the host PCIe fabric; and
enumerating, by a root complex end point (RCEP) of an extended PCIe fabric, endpoints of the host PCIe fabric,
wherein the RCEP is an endpoint of the host PCIe fabric and a root complex of the extended PCIe fabric,
connecting, by the host root complex, the endpoints of the host PCIe fabric using a first set of bus numbers; and connecting, by the RCEP, the endpoints of the extended PCIe fabric using a second set of bus numbers separate from the first set of bus numbers.
