How many controllers can be a part of Clustering in AOS 8.0?
It depends on the hardware model or the devices used in clustering.
If we are using only 72xx controllers in a cluster deployment, then we can have upto 12 nodes in a cluster.
If we are using 70xx controllers and VMC devices, upto 4 nodes can be a part of the cluster.
In case of RAP deployment only 4 nodes are supported in the cluster.
