Chapter 2 Product Description
Ethernet redundancy
From the factory, the ports on the four port Ethernet adapter are teamed using Adapter
Fault Tolerance (AFT) software provided by the network adapter vendor, such as
Intel. This provides automatic redundancy for the Ethernet connections. One AFT
team is dedicated to the command and control network connection in Profile storage
systems. The other is dedicated to streaming media transfers.
Adapter Fault Tolerance (AFT) is achieved by a team of two or more adapters
configured to provide a backup network connection. AFT teams have a primary
adapter and a backup, or secondary, adapter. During normal operation, only the
primary adapter transmits traffic. If the primary adapter or the link to the primary
adapter fails due to switch, port, cable, or remote adapter failure the secondary adapter
automatically takes over. For more information on fault tolerance, refer to the online
documentation provided with the teaming software configuration tool.
NOTE: If you are using redundant network connections, ensure that the Ethernet
switches used support Spanning Tree Protocol (STP), and that the protocol is
configured as described in
“Redundant Ethernet network requirements” on
page 17 .
