B-40 Installing the Operating System
Setup of Adapter Fault Tolerance (AFT)/Adaptive Load
Balancing (ALB)
Adapter Fault Tolerance (AFT) is a feature that creates a group containing more than one adapter.
With this feature, when the working adapter gets any problem, the process on it is automatically
transferred to the other adapter in the group.
Adaptive Load Balancing (ALB) is a feature that creates a group containing more than one adapter
and enhances the throughput by operating packet transmission from the server by all the adapters.
This feature includes AFT feature.
IMPORTANT:
All the adapters specified as a group of Adapter Teaming must exist
on the same LAN. If they are connected to the separate switches,
they will not work normally.
The adapters specified as a group of Adaptive Load Balancing
(ALB) can be connected to only Switching Hub.
When exchange the mother board or option network card, make sure
to remove the adapter team before exchanges and recreate the
adapter team after exchange complete.
Verify that the switch fully supports the IEEE 802.3ad standard
before using IEEE802.3ad Link Aggregation (DLA).
