Configuring high availability

The solution architecture allows maintaining high availability of SD-WAN instances in the event of shutdown or overload of virtual machines, CPE devices, and SD-WAN Controllers. High availability of these components is achieved by installing redundant devices and connections between them.

We recommend that you take into account the need for high availability of solution components when deploying an SD-WAN instance.

To configure high availability:

1. In the menu, go to the SD-WAN → SD-WAN instance templates subsection.

   A table of SD-WAN instance templates is displayed.

2. Click the SD-WAN Instance template.

   The settings area is displayed in the lower part of the page. You can expand the settings area to fill the entire page by clicking the expand button .

3. Select the High availability tab.

   The high availability settings are displayed.

4. Select the number of SD-WAN Controller nodes to use when deploying an SD-WAN instance.
5. Click Save in the upper part to save the configuration of the SD-WAN instance template.
