Installation in cluster environment

You can deploy ESET Mail Security in a cluster environment (for example, in a failover cluster). We recommend that you install ESET Mail Security on an active node and then redistribute the installation on passive node(s) using the ESET Cluster feature of ESET Mail Security. Apart from the installation, the ESET Cluster will serve as a replication of ESET Mail Security configuration to ensures consistency between cluster nodes necessary for correct operation.
