is there any throughput advantage when it comes two a file server with 2 NIC's. Is there a throughput advantage in teaming the NIC's vs. non teaming the NIC's?

Thanks.

Yes there is always advantage with NIC teaming, but it depends on how the NICs are configured.
You can get the detailed on NIC teaming at this link

There is definitely advantages to teaming your NICs but there are design considerations to take into mind as well. For instance if both NICs connect to different switches active/active balancing between the two probably isn't a good idea unless you know the rest of the environment is proper. In addition to the link above, you should look into a vendor provided drive/option as those tend to work better. For instance HP and Dell both have 'teaming' software for their nics which makes them present to the system as 1 active interface with the aggregate bandwidth of the whole, and/or allowing active/passive failover, etc

If you will configur as load balance, you will definetly see th gain in performance. But if for fault tolerance, then you won't see any performance gain.

with the hp teaming software, you can generally leave it to 'automatic' and it'll decide which policy works best. it's a good thing regardless of performance to have multiple links in case somebody unplugs one accidentally. the only reason not to team them would be if you didn't have the switch ports available. at least that's my 2-cents
