Claim 0:
1. A system for extending a peripheral component interconnect express (PCIe) fabric, comprising:
a host root complex of a host PCIe fabric; and
a root complex end point (RCEP) of an extended PCIe fabric, wherein the RCEP is an endpoint of the host PCIe fabric and a root complex of the extended PCI e fabric,
wherein the host root complex is configured to enumerate endpoints of the host PCIe fabric, and the RCEP is configured to enumerate endpoints of the extended PCIe fabric,
wherein the host root complex is further configured to connect to the endpoints of the host PCIe fabric using a first set of bus numbers, and the RCEP is further configured to connect to the endpoints of the extended PCIe fabric using a second set of bus numbers separate from the first set of bus numbers.
