Failover feature allows you to provide high availability setup of SMSEagle devices in uptime-critical environments.
Enhance the reliability of your communications with SMSEagle’s HA-cluster failover solutions, designed to keep your SMS connectivity uninterrupted even in the most demanding environments. This powerful system automatically switches to back up resources to prevent downtime, giving you peace of mind and ensuring your critical messages are always delivered without delay.
SMSEagle devices has its own failover mechanism based on HA-cluster. This feature allows you to assure high availability of SMSEagle devices in uptime-critical environments. To enable failover (HA-cluster) you need at least 2 devices (‘aka’ nodes). The failover feature monitors devices and detects faults with the most vital services (web server, database engine, modem software, modem connectivity, SNMP agent, accessibility of whole node).
In the cluster you have one MASTER device and one BACKUP device. HA-cluster is accessed via Virtual IP address.
Every node in HA-cluster can have one of three states:
When HA-cluster detects failure of at least one function of MASTER device it immediately switches cluster’s IP assignment to the BACKUP device (node) providing continuous usage of the SMSEagle HA-cluster for a user.
Failover cluster can be easily configured using Web-GUI. For each device in failover cluster:
Save configuration. Reboot each device after saving. The configuration should be exactly the same on both devices in HA-cluster.
