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