Recommendations for 25G SFP28 NICs

Hey folks, this might a bit more for /sysadmin, but we're looking at running 25G between our ToR switches (most likely FlexFabric 5950's) and servers and was hoping to get some input from some of you early adopters.

We haven't touched a lot of 25G yet and our VARs aren't very technical so I was looking for some advice or recommendations on which brand of NICs to use. Thinking mostly about reliability, driver support and performance. Servers will be running Linux (Ubuntu) and won't be doing anything crazy so most cards cover our required feature sets.

We're looking at:

  • Broadcom (BCM57414)
  • Mellanox (ConnectX-4 Lx EN)
  • QLogic (41262)
