Abstract
Described herein are enhancements for deploying a Peripheral Component Interconnect Express (PCIe) switch in a computing enclosure. In one implementation, a PCIe switch is coupled to a plurality of hosts and at least one network interface via PCIe lanes. The PCIe switch is configured to exchange communications between the plurality of hosts and the one or more physical network interfaces and emulate, to each host of the plurality of hosts, a physical network interface. The PCIe switch is further configured to receive a communication from a first host of the plurality of hosts directed at a second host in the plurality of hosts using an emulated physical network interface for the first host, and transfer the communication to the second host as though the communication were received at an emulated physical network interface for the second host.
