Active/Active Clustering Full Mesh configuration is an enhancement to the Active/Active Clustering configuration option and provides the highest level of availability possible with high performance. Full Mesh deployments provide a very high level of availability for the network, because all devices have one or more redundant partners, including routers, switches, and security appliances. Every device is wired twice to the connected devices, so that no single point of failure exists in the entire network. For example, every SonicWall firewall uses redundant ports to connect twice to each networking device.
For more information about Full Mesh deployments, see the Active/Active Clustering Full Mesh Deployment Technote, available on https://support.sonicwall.com/.

You can also configure a Full Mesh deployment using only two firewalls, one per Cluster Node, as shown in Two-Unit Full Mesh Deployment.
