Installation in cluster environment

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