Too bad they didn't mention that while the cable is direct attach, the ends each have an EEPROM in them saying what the cable is. This EEPROM can be a source of immense frustration, if it's got the wrong data in it, or if both ends do not agree.
This should be higher up for anyone considering DACs for homelab use. I had a lot of issues due to this when mixing Aruba switches with Intel nics in my rack. Ended up going to fiber and SFPs.
