Considerations
Windows NT versions prior to 4.0 do not support Adapter Teaming
options.
Adapter Teaming options require NT 4.0 with Service Pack 4.0 or later
(or Service Pack 3.0 and the Windows Hot Fix).
In Windows NT, teaming options cannot be implemented on adapters
that have been configured for VLANs. NetWare can support teaming
options and VLANs on the same adapters.
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.
Adaptive Load Balancing
Adaptive Load Balancing (ALB) is a simple and efficient way to increase
your server's transmit throughput. With ALB you group server
adapters in teams to provide an increased transmit rate (up to 8 Gbps)
using a maximum of eight adapters. The ALB software continuously
analyzes transmit loading on each adapter and balances the rate across
the adapters as needed. Adapter teams configured for ALB also
provide the benefits of AFT. Receive rates remain at 100 Mbps or
1 Gbps depending on the primary adapter's capability.
To use ALB, you must have two to eight server adapters installed in
your server and linked to the same network switch.
