Glossary of Terms: SQL Failover
Definition: When clustering software detects a failure in the primary cluster node, it moves operation of the SQL Server to the secondary node in the cluster in a process called failover. Since the secondary node has access to the same data as the primary node, operation continues without downtime or data loss.
