alt Hacker NewsWhen I did server room buildouts for VFX, I used to use DAC for short distance and fibre for anything longer than a rack.
However that was mainly because I always thought fibre was much more fragile. I mean in a sense it is, it really doesn't like being pull through a thatch of other wires. The solution of course is to do nice cabling.
Nowadays I'm not actually sure if DACs are cheaper than fibre now

Yep still are, although fiber transceivers are surprisingly affordable, and of course you can usually re-use jumpers when you upgrade transceivers so TCO over a couple generations might be comparable.
