NOTE:

Dual Channel Network Fault Tolerance teaming capabilities are not supported on

systems running Windows® 2000.

Switch-assisted Dual Channel NFT
Switch-assisted Dual Channel NFT requires a minimum of two adapters in a channel team and a minimum

of one adapter per group. When you select Switch-assisted Dual Channel NFT, the Team Members

window becomes team members grouping and displays two windows labeled Group 0 and Group 1.
Switch-assisted Dual Channel NFT and Preference Order
Provides the same options as Switch-assisted Dual Channel Network Fault Tolerance except it offers the
additional option to select the priority order of the group (Group 0 or Group 1) used for the primary and

secondary teams.
802.3ad Dynamic Dual Channel NFT
Dynamic Dual Channel NFT requires a minimum of two adapters in a channel team and a minimum of

one adapter per group. All team members within each group are dynamically placed into a port-
trunk/channel by dynamic LACP agreement with the switch. It provides the safety of additional backup

links between the server and hub/switch. One channel team provides a primary adapter and another

channel team provides a secondary, backup adapter. If the adapters in the primary team fail, a link to

one of the adapters in the secondary, backup team automatically takes over.
802.3ad Dynamic Dual Channel NFT and Preference Order
Provides the same options as 802.3ad Dynamic Dual Channel NFT except it offers the additional option

of setting the priority order of the adapters that are used in the primary and secondary teams.
Dual Channel Load Balancing
Dual Channel Load Balancing allows the creation of two teams, called groups, inside of a single team.
Each group is assigned one or more teamed ports. Each group can also be connected to a different

switch to provide switch fault tolerance. Full inbound and outbound load balancing is provided across

both groups. Should any group completely fail, caused by a failure of all teamed ports in the group or by

a failure of the group's switch, the team remains available through the other group.
Two types of Dual Channel Load Balancing teams can be configured:

Switch-assisted Dual Channel Load Balancing teams

802.3ad Dynamic Dual Channel Load Balancing team

Switch-assisted Dual Channel Load Balancing teams
The Switch-assisted Dual Channel Load Balancing team type allows you to define one group of team

members to be treated as a Switch-assisted Load Balancing (SLB) group to one switch, and a second

group of team members to be treated as an SLB group to a second switch.
With Switch-assisted Dual Channel Load Balancing, all transmit packets are load balanced among all

team members based on a load balancing algorithm in the teaming device driver. The receive packets
are load balanced among all team members by both the switch and the team. If a failure of any team

member occurs, the packets are load balanced among the remaining adapters.
There must be a minimum of two adapters in a Switch-assisted Dual Channel Load Balancing team with a

minimum of one adapter in each group. Only Gigabit adapters can be used for Switch-assisted Dual
Channel Load Balancing.
