The failover target assumes the network identity of the failed source. When the target
assumes the identity of the source, user and application requests destined for the source
server or its IP address(es) are routed to the target.
When partnered with the Storage Mirroring Recover data replication capabilities, failover
routes user and application requests with minimal disruption and little or no data loss. In
some cases, failover may be used without data replication to ensure high availability on
a server that only provides processing services, such as a web server.
