## Solution

These are the maximum numbers of supported members in a cluster:

* Up to 5 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](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk105170))

Note: In Crossbeam DBHA configuration, the above requirement applies to a single chassis (Check Point code is not aware of DBHA).

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.  

**Notes**:

* For information on supported cluster members in ElasticXL, see the [Scalable Platforms Administration Guide](https://sc1.checkpoint.com/documents/R82.10/WebAdminGuides/EN/CP_R82.10_ScalablePlatforms_AdminGuide/Content/Topics-SPG/ElasticXL/ElasticXL-Important-Notes.htm?tocpath=Working%20with%20ElasticXL%20Cluster%20%7C_____1) for your version.
