Computer, end program.

Well, google is out of my deterministic universe or whatever you call it. I can live without google gods as I've been for the past 10 years. I use mostly my search engine and duckduckgo.com witch uses google algorithm and filter all the crap google feeding you. If you get no match then there is no much even if google match you with a few million crap pages that have nothing to do with what you looking for. also duckduckgo.com have tor link page on the TOR network where you can match your search more accurately without all of that censorship that filter your taffic, but anyway
I know I can't get 40G speed from my HDDs all I need is to make sure the adapter is operating properly (at 40G speed) in freeNAS and if possible not to spend time on long line coding the adapter just to run it. I know I have to make some adjustments

Thank you

I have the MCX314-BCBT (2015/12/11 - rev: AB). According to the manufacturer the MCX314A-BCCT is the pro version (RoCEv2* & stuff). The BCBT I have just worked right out of the box.

*edit: as far as i understood the manual, RoCEv2 only on pro version

I can't find this card on eBay I found MCX314A-BCBT are they the same ?
but the pro version is not a bad price is used but I never had problems with this type of used equipment

I just tested the
Mellanox ConnectX-3 MCX314A-BCCT
on the esxi with Direct Patch I/O and it can't started
see attachment

Simple answer is not to use esxi

I have 5 of these cards, I run them in Linux routers, freenas, and pfsense(with a little extra work)

Never had a single issue once I got past tuning it correctly

I think pass trough I/O is the same as installing it on bare metal isn't it. If there is no driver !!!
Can you tell me how did you tune adapter that is not showing on freenas I am a newbie in freenas and freebsd

Do you have some guide how to install the driver for this adapter

Thank you
