The synchronization network is used to pass connection synchronization and other state information between cluster members. State Synchronization between cluster members ensures that if there is a failover, connections that were handled by the failed machine will be maintained. The cluster has one external virtual IP address and one internal virtual IP address. In the previous illustration, the IP address of the cluster is 192.168.10.100. This configuration is not recommended and should be used for backup only.ĭefining the Cluster Virtual IP Addresses Note - This release presents an option to use only two interfaces per member, one external and one internal and to run synchronization over the internal interface. This is the External interface with IP address 192.168.10.1 on Member_A and 192.168.10.2 on Member_B, and is the interface that the cluster external interface sees. Each has an interface with an IP address facing the Internet through a hub or a switch.

Example ClusterXL TopologyĬlusterXL uses unique physical IP and MAC addresses for each cluster member, and a virtual IP addresses for the cluster itself. All connections are shared between the remaining gateways without interruption. If any individual Check Point gateway in the cluster becomes unreachable, transparent failover occurs to the remaining operational machines in the cluster, thus providing High Availability. In Load Sharing configurations, all functioning machines in the cluster are active, and handle network traffic (Active/Active operation). Load SharingĬlusterXL Load Sharing distributes traffic within a cluster of gateways so that the total throughput of multiple machines is increased. The glue that binds the machines in a ClusterXL cluster is the Cluster Control Protocol (CCP), which is used to pass synchronization and other information between the cluster members.

The cluster members synchronize their connection and status information across a secure synchronization network. Enhanced throughput (in Load Sharing modes)Īll machines in the cluster are aware of the connections passing through each of the other machines.Zero downtime for mission-critical environments (when using State Synchronization).
