So I have FreeNAS inside ESXi running on my R710, and I want to connect the server directly to my PC for performance improvements to my iSCSI. I'm really new to 10GbE and beyond, but I found two cheap options with SFP and QSFP but I want to make sure that I don't go buying something I can't use.

​

SFP

Cable: https://www.ebay.com/itm/Arista-CAB-SFP-SFP-7M-10G-SFP-Passive-Copper-Cable-7-Meter-or-23-Feet/303257002612

QSFP

Cable: https://www.ebay.com/itm/FCBG410QB1C10-Finisar-Quadwire-40Gb-s-QSFP-Parallel-Active-Optical-Cable-10M/202750685411?hash=item2f34e1f0e3:g:m0EAAOSwYw1dSQXI&LH_BIN=1

My goal is either to either passthrough the NIC straight to FreeNAS, or in the event that FreeNAS doesn't support it, let ESXi handle the NIC and continue virtually switching to the FreeNAS VM. I want to run that directly to my Windows 10 PC and I'd prefer to do it on as cheap a budget as possible, as I just did some upgrades and had to replace a mobo on the PC.

If I could get any advice on these, or even other options, I would really appreciate it!

​

Edit:

The people on the Discord convinced me to push my budget and get the Mellanox ConnectX-3's, so I'm going with that and the optical cable. Hopefully that should have me all set for my first < 1Gb/s line.
