Failover Architecture
You can configure LogLogic appliances in a one-to-one HA pair failover configuration.
There is a single active appliance with a single standby appliance. The standby appliance continually stays in sync with the active appliance and automatically takes over for the active appliance if a problem arises.
Each appliance has its own private IP address. The HA pair itself has a public IP address, which serves as the single entry point for the HA pair. All external systems point to the public IP address so data goes to the active appliance in the HA pair regardless of which appliance it is at a given time.
LogLogic failover is built on three software layers that together ensure failover membership, database replication, and recurring node resynchronization.
