$54 OBO for Chelsio S320E LP CR Dual 10 Gbps PCIe x8. Wondering if it's a fair buy? Looking for use with EXSi, FreeNAS, and Windows (7-10).
FYI: the Intel X520-DA2 is on the ESXi HCL
, I would think the X520-DA1 by extension would work as well, but the X520-DA1 is not showing up on the list
Intel x520-DA2(/-DA1) compatible SPF/SPF+ modules includes Intel, Avago, Finisar, and HP Gigabit SX modules.

@epicurean For ESXI I would get the X520 hands down. They are some of the best supported cards around and have a giant installed base.
Just put an X520 DA1 into my esxi 6 server and it was plug and play.
I have 2 connectx 2 between a microtek switch , workstation win10 pro 64bit and my Unraid 64bit server and only seem to get around 350mbps max i ever saw when transferring from files , from SSD to SSD. At times the connection will drop low into the mid 30's for some reason. kinda ticks me off and i need to research why... OK now to the question would these Intels cards be better supported in Win10 pro then the Connectx 2 cards? better thru put ? Seems like Intels site for this card still has support..
The intel cards would be no faster the rate limiting process here is single ssd to ssd transfer. But beyond that there are some Linux networking stack optimizations that need to be performed with unraid to run at the full 1gb/s . Linus had a video briefly talking about this issue with unraid and windows 10. But didn't go into detail about what unraid suggested but I'm sure they are optimizing jumbo frames send and receive buffers and RSS. I have a few of these connectx2 sfp, vpi, and connectx3 vpi nice and I can scale them to full bandwidth from Windows 10 and windows server 2012r2 and 2016. With rdma transfers I have hit 20 gigabytes per second transfers with 7 connectx2 vpi nics from Windows server to windows server.

I know this is a very old, like very old thread.... but hey i used the search bar!!! LOL
I was just on Aliexpress and found these cards for $5 each...
so is this still the good thing to go with?
I have old connectx-1 and connectx-2 using a specific port called CX4 (to not be confused with ConnectX-4)...

oh i see now... they default showing the NIC but it is just the SFP+ module for $4... card is $23...There is a limit 1 per customer, i was able to buy it - nic + sfp+ module - 6 euro incl. delivery to EU
screenshot from my invoice attached.
how about going this route? rj45 - no limit on purchase and when you bulk in shipping, we are talking $~10 each

i am now seeing all the fakes out there.. interesting stuff. Even if you buy new on Amazon, you need to inspect each card and make sure you have a true card!!!!
I got burned recently on the x520 nics ... :/ bought 5 of them and they wont accept the DAC, got a few other x520 around with no issues on the same DACs
i was contemplating the rj45s to not deal with DAC...
in all honesty, i dont need all this i have.. could seriously downgrade and just buy another x520 off of amazon... that way i can return it no matter what.
Did you buy via credit card? That is what I am thinking of doing if I dont go amazon to then leverage fraud protection on my CC. Figured i would call them first to make sure...
