Product Documentation

StrongKey Tellaro Appliances are always installed in a clustered configuration for HA in a production environment. All the servers function in a master-master where any server can receive transactions and will asynchronously replicate data records between all other nodes in the cluster.

When KeyAppliance software stack gets installed on StrongKey Tellaro appliances, it includes a ZeroMQ (ZMQ) module which is responsible for replication of database objects among nodes in the cluster. It uses 3 ports for replication between nodes of the cluster: 7001, 7002, 7003.
