A VSX Cluster has two or more identical, interconnected VSX Gateways for continuous data synchronization and transparent failover. Virtual System Load Sharing (VSLS) enhances throughput by distributing Virtual Systems, with their traffic load, among multiple, redundant machines.
For more about Check Point ClusterXL features and functionality see the R80.20 ClusterXL Administration Guide.
VSX supports High Availability and transparent failover for VSX Gateways and for Virtual Systems. If the Active VSX Cluster Member fails, all sessions continue to run, securely and without interruption, on a Standby VSX Cluster Member. Users stay connected and do not notice the failover. They are not required to authenticate again on failover.
Use Selective Sync to activate, delay, or disable VSX Cluster Member synchronization.
Load Sharing offers significant performance advantages while providing failover for individual Virtual Systems. Using multiple Gateways instead of a single gateway significantly increases performance for CPU intensive applications such as VPNs, Security Servers, Policy Servers, and Active Directory (LDAP).
By distributing Virtual System instances between different VSX Cluster Members, the performance load is efficiently spread amongst the VSX Cluster Members. For example, Active Virtual System 1 runs on VSX Cluster Member A, while Active Virtual System 2 runs on VSX Cluster Member B. Standby and Backup Virtual System instances are likewise distributed amongst VSX Cluster Members to maximize throughput, even in a failover scenario.
VSLS provides an excellent scalability solution, allowing administrators to add additional VSX Cluster Members to an existing VSLS cluster as traffic loads and performance requirements increase.
