Hardware VTEP for multi-rack deployments

Hardware VTEP for multi-rack deployments

  • Dell Technologies recommends selecting network switches that support hardware-based Virtual Tunnel Endpoints (VTEP) for multi-rack deployments. This feature is beneficial for customers expecting to deploy VxRail clusters over multiple racks, and do not want to extend the Layer 2 networks across racks. This feature is also beneficial in avoiding a rack being single point of failure, as the virtual machines in the management workload domain can migrate between racks without the need to change the IP address.

    The feature supports the bridging of Layer 2 network traffic VxRail nodes in different racks through packet encapsulation and decapsulation on a Layer 3 overlay network. This feature optimizes VxRail network traffic across racks in a multi-rack cluster by eliminating the need to route through upstream routing services.
