Basically will the combination listed in the title work?
Bit of background:
A while ago I got my hands on 2x XL710 cards and an optical DAC cable for very little money.
Basically I have sweet 40G connection between my main PC and the FreeNAS server.
However now I want to move the server into a different room and the cable is too short.
Also I dont really want to drill massive holes for the QSFP connector to pass the cable to the next room.
One option would be 40G optical modules but with Intel locking other vendors out, the E40GQSFPSR module is a pricey option.
The multi-fiber cables are somewhat expensive as well and the MPO connector is almost a big as the module itself.
I would be willing to drop down to 10G however.
Intels 10G SR module is somewhat cheap, the cables are super-cheap and the LC connector is reasonably small.
However I would like to avoid having to buy 2x X710 cards as well.
And that is how we arrive at the combination mentioned in the title.
Unfortunately Intel does not offer QSFP-SFP adapters itself and I would like to avoid a bad buy or even damaging any equipment.
Any guidance is highly appreciated :)
