How does the SnapServer (GuardianOS) Failover option work
This information is not Operating System specific
The SnapServers' (GuardianOS) redundant network interfaces ensure that an active port is available at all times. If the primary port (Ethernet1) fails due to a hardware or cable problem, the secondary port (Ethernet2) assumes its network identity. Ethernet2 uses IP aligning and assumes the MAC and IP addresses of Ethernet1. The transition is transparent to users, although some users may experience a few seconds of inactivity. If the failed port comes back online, it resumes its role as the primary interface. The Failover mode ensures server availability to the network, however it does not provide switch-fault tolerance.
