What is the maximum number of members supported in Check Point cluster?
The following are the maximum numbers of supported members in a cluster:
- Up to 8 cluster members are supported in ClusterXL (in Load Sharing mode, configuring more than 4 members significantly decreases cluster performance due to amount of Delta Sync).
- Up to 5 cluster members are supported 3rd party cluster (in Crossbeam chassis, configuring more than 4 members (APMs) significantly decreases cluster performance due to amount of Delta Sync).
- Up to 2 cluster members are supported in VRRP cluster running Gaia OS (refer to sk105170)
Note: In Crossbeam DBHA configuration, the above requirement applies to a single chassis (Check Point code is not aware of DBHA).
Refer to sk93306: ATRG: ClusterXL R6x and R7x - Chapter "Introduction to ClusterXL" - section "ClusterXL requirements for hardware and software" - "Requirements for number of cluster members"
If state synchronization is used in the cluster, then the recommended maximum number of nodes is 4 regardless of the clustering mode used.
VSX VSLS uses a more efficient state synchronization method and can safely support more than 4 nodes in a cluster.
