NSX segments

  • Segments are used to connect VMs to Layer 2 networks, and they can be either VLAN or Overlay segments. For the Mgmt WLD, when the NSX Edge Nodes and AVNs are deployed from SDDC Manager, two segments are created for the AVNs—Region A and X-Region—to be used for the VMware Aria Suite of components. You can create overlay-backed NSX segments or VLAN-backed NSX segments. Both options create two NSX segments (Region-A and X-Region) on the NSX Edge cluster deployed in the default management vSphere cluster. Those NSX segments are used when you deploy the VMware Aria Suite products. Region-A segments are local instance NSX segments; X-Region segments are cross-instance NSX segments. Two segments are created to allow Edge Node traffic to flow through the ESXi hosts to the physical network. The following table shows the segments that are created to support AVN in the virtual infrastructure of the SDDC.

    For the VI WLD, the Edge automation is used to deploy the NSX Edges from SDDC Manager. The Edge uplink segments are created at this time. Segments for workloads are created as a Day-2 activity outside of SDDC Manager.
