Yeah I know other networking gear vendors usually tend to be d*cks and milk for branded parts that's why I asked more about server cards. All my networking gear is mtk so no surprises to expect here. I was just wondering if I'll need to get full set of quite pricey SFP+ modules or I could get away with mtk DAC cables for connection between CRS317 and Linux servers with Intel x710 cards.Hi, according to my experience at 10Gbps DAC, some cables are standard by brand, if you want to connect the mikrotik with an Intel PC, it will probably work; if you're trying to connect different mikrotiks using that DAC the it will definitely work, however if your idea is to connect to a different vendor like Cisco / Juniper then it won't work, because they add something called CRC which is a kind of coding for that vendor and the other end will not recognize that cable.

From my experience with Intel 10 GbE drivers, at least some include an option to use unsupported SFP+ modules at your own risk.I ordered Intel compatible DAC cable. I hope it's gonna work :/ I'm starting to be a bit afraid that this card is from some OEM and accepts eg only HP or Dell parts... I bought it in some standard consumer electronics shop. dmesg shows following message:
