Edges can be installed as a single standalone device or paired with another Edge to provide High Availability (HA) support. However, the HA configuration is supported only on wired WAN connections.

HA Options

When you configure the Edges in HA mode, the Edges automatically select one of the following options:

  • Standard HA – This option is selected when both the Active and Standby Edges are connected to the same WAN links.
  • Enhanced HA – This option is selected when the Edges are connected to different WAN links.

The HA options are supported on the following SD-WAN Edge platforms: 510, 510N, 520, 520v, 540, 610, 610N, 620, 620N, 640, 640N, 680, 680N, 840, 2000, 3400, 3800, and Virtual Edge.

Note: HA is supported only between identical SD-WAN Edge platform models. For more information on the Edge platform models, see https://sdwan.vmware.com/get-started.
Note: Mixing Wi-Fi capable and Non-Wi-Fi capable Edges in High Availability deployments is not supported. While the Edge models 510N, 610N, 620N, 640N, and 680N appear identical to their Wi-Fi capable counterparts, deploying a Wi-Fi capable Edge and a Non-Wi-Fi capable Edge of the same model (for example, an Edge 640 and an Edge 640N) as a High-Availability pair is not supported. Customers should ensure that the Edges deployed as a High Availability pair are of the same type: both Wi-Fi capable, or both Non-Wi-Fi capable.
