1.4 Redundant Hardware Configurations

You can install redundant hardware instances of Corente Services Gateways for high availability and to allow you to perform maintenance tasks.

A redundant hardware installation consists of two Corente Services Gateways that use the same configuration, a primary instance and a redundant, or failover, instance. You configure both instances with dedicated back-channel network interfaces that are connected through a network device such as a hub or switch. The primary and failover instances then communicate through the back-channel network interface on a the 1.1.1.1/30 subnet. The failover instance detects if the primary instance becomes unavailable and then automatically takes over.
