Application Considerations
To understand how backup data streams are directed during network failover
process, consider the topology in
data to the backup server through Path 1, but a link failure occurs between the
backup server and the switch. Because the data can no longer be sent from
Switch #1 to the Adapter A interface on the backup server, the data is redirected
from Switch #1 through Switch #2, to the Adapter B interface on the backup
server. This occurs without the knowledge of the backup application because all
fault tolerant operations are handled by the adapter team interface and trunk
settings on the switches. From the client server perspective, it still operates as if it
is transmitting data through the original path.
