VMware NSX Data Center is a network virtualization platform for the software-defined data center (SDDC), delivering networking and security entirely in software, abstracted from the underlying physical infrastructure.

NSX enables guest virtual machines running under the ESXi hypervisor to attach to virtual networks. Traffic flowing on these virtual networks can traverse arbitrary routed IP network topologies, by encapsulating their traffic using the VXLAN protocols and forwarding that traffic through tunnels configured between points in the IP network.

The Lenovo® NSX Gateway, which was introduced in RackSwitch™ products starting with CNOS 10.8, enables servers which are not part of the NSX environment to attach to NSX virtual networks and communicate with other servers, real or virtual, which are attached to those same virtual networks.

This paper describes the functionality of the NSX gateway as implemented on Lenovo switches. It is suitable for technical and managerial individuals working in environments where NSX is used.
