Network Teaming Features
NOTE
Using both on-board NICs in a team does not allow the use of NIC 1 for
server management access. To support both network teaming features and
server management features, a third NIC must be added and teamed
to NIC 2.
The network controller provides several options for increasing throughput and fault tolerance when
running Linux
†
:
• Adapter Fault Tolerance (AFT) - provides automatic redundancy for your adapter. If the
primary adapter fails, the secondary takes over. AFT works with any hub or switch.
• Adaptive Load Balancing (ALB) - creates a team of 2 adapters to increase transmission
throughput. Also includes AFT. Works with any 10Base-TX or 100Base-TX switch.
• Fast EtherChannel
†
(FEC) or Intel
®
Link Aggregation - creates a team of up to 6 adapters to
increase transmission and reception throughput. Also includes AFT. Requires a FEC-enabled
switch.
To set up an option, read the instructions in the Linux readme files.
Adapter Fault Tolerance
Adapter Fault Tolerance (AFT) is a simple, effective, and fail-safe approach to increase the
reliability of server connections. AFT gives you the ability to set up link recovery to the server
adapter in case of a cable, port, or network interface card failure. By assigning two server adapters
as a team, AFT enables you to maintain uninterrupted network performance.
AFT is implemented with two server adapters: a primary adapter and a backup, or secondary,
adapter. During normal operation, the backup will have transmit disabled. If the link to the
primary adapter fails, the link to the backup adapter automatically takes over.
