• No Single Point of Failure in the Core Network: In an Active/Active Clustering Full-Mesh deployment, there is no single point of failure in the entire core network, not just for the firewalls. An alternative path for a traffic flow is always available in case there are simultaneous failures of switch, router, firewall on a path, thus providing the highest levels of availability.
• Port Redundancy: Active/Active Clustering Full-Mesh utilizes port redundancy in addition to HA redundancy within each Cluster Node, and node level redundancy within the cluster. With port redundancy, a backup link will take over in a transparent manner if the primary port fails. This prevents the need for device level failover.Redundant ports can be used along with Active/Active Clustering. If one port should have a fault, the traffic is seamlessly handled through the redundant port without causing an HA or Active/Active failover. A Redundant Port field in the Network > Interfaces > Edit Interface page becomes available when Active/Active Clustering is enabled.
