Clustering

March 26, 2020 Contributors

The clustering capabilities of the product enable the following features:

  • Centralized management of configuration for multiple MTA nodes

  • Replicated, redundant, configuration repository with revision control

  • Log aggregation pulls log files from MTA nodes to centralized location(s) on the network

  • Replication of a variety of real-time metrics to allow cluster-wide coordination for inbound and outbound traffic shaping

  • DuraVIP™, our IP Failover mechanism.

Clustering is based on the concept of having a cluster of machines that communicate using a group communication message bus. Ideally, a cluster will have a dedicated gigabit network for transmission of replicated data and internal message moves.

The product assumes that the cluster network is a trusted network, meaning that it leaves host based authentication to be implemented by the network administrator at an appropriate firewall on the network.
