Advanced team types
The advanced team types provide a selection of fault-tolerant and load-balancing features,
including Network Fault Tolerance (NFT), Transmit Load Balancing (TLB), and Switch-assisted
Load Balancing (SLB).
Dual Channel Network Fault Tolerance
Dual Channel NFT provides the safety of additional backup-links between the server and
hub/switch. It is implemented with one channel team providing a primary adapter and another
channel team providing a secondary, backup adapter. During normal operations, if the adapters
in the primary team fail, a link to one of the adapters in the secondary, backup team automatically
takes over.
Four types of Dual Channel NFT teams can be configured:
•
Switch-assisted Dual Channel NFT
• Switch-assisted Dual Channel NFT and Preference Order
• 802.3ad Dynamic Dual Channel NFT
• 802.3ad Dynamic Dual Channel NFT and Preference Order
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 porttrunk/ 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
