How many vManage devices are recommended for deployment in an SD-WAN setup?

In an SD-WAN setup, it is recommended to deploy an even number of vManage devices, specifically two, to ensure high availability and redundancy. The two vManage instances operate in an active-standby configuration. This setup provides a failover mechanism, ensuring that if one vManage device goes down, the other can take over without significant disruption to network operations.

Using two vManage devices also allows for load balancing and can facilitate maintenance, where you can perform updates or changes on one device while the other remains operational. This redundancy helps in maintaining continuous management and monitoring of the SD-WAN environment, contributing to the overall resilience of the network.

Deploying more than two vManage devices, while possible, would generally add unnecessary complexity, especially for smaller or medium-sized deployments. It's essential to balance redundancy with operational overhead to keep the environment manageable and efficient.
