Network Fault Tolerance Only (NFT)

Network Fault Tolerance (NFT) is the foundation of HP Integrity Network Adapter Teaming.
In NFT mode, from two to eight teamed ports are teamed together to operate as a single virtual
network adapter. However, only one teamed port–the Primary teamed port–is used for both
transmit and receive communication with the server. The remaining adapters are considered to
be standby (or secondary adapters) and are referred to as Non-Primary teamed ports. Non-Primary
teamed ports remain idle unless the Primary teamed port fails. All teamed ports may transmit
and receive heartbeats, including Non-Primary adapters.
The fault-tolerance feature that NFT represents for HP Integrity Network Adapter Teaming is
the only feature found in every other team type. It can be said that the foundation of every team
type supports NFT.
NFT is a basic feature of HP Integrity Network Adapter Teaming. Refer to
Advanced Teaming"

Network Fault Tolerance Only with Preference Order

Network Fault Tolerance Only with Preference Order is identical in almost every way to NFT.
The only difference is that this team type allows the SA to prioritize the order in which teamed
ports should be the Primary teamed port. This ability is important in environments where one
or more teamed ports are more preferred than other ports in the same team. The need for ranking
certain teamed ports better than others can be a result of unequal speeds, better adapter capabilities
