100Gb NIC Recommendations

[swezey]

Hi, iXians! We're getting ready to add a Dell S6100-ON 40/100 Gb switch and are looking for suggestions for a compatible 100Gb NIC to connect our two FreeNAS boxes at 100Gb. We have Chelsio 40Gb NICs ATM. Does anyone have a good suggestion? It can be a single port or dual port but we are probably only going to use a single port at the moment because we only have 8 100Gb ports on the switch right now and we need room for the servers as well. Any help is appreciated. Thanks!

Bill

P.S. Both FreeNAS boxes are SuperMicro one with an X10DRH-iT motherboard and the other with an X8DT3/X8DT motherboard.

Sorry, we are running TrueNAS Core - old habits die hard - version TrueNAS-12.0-U8.1.

Your X8DT3 Board supports PCIE x8 Gen2 highest, don’t think a 100Gb NIC exists for that. 100Gb NICs comes with PCIE x16 Gen3 or Gen4.
There is simply not enough bandwidth for such a card with this board.
