Oh man --- The trolling here is amazing!!! First off, you can't just plug a fiber cable into an ethernet socket. You need at least SFP+'s for 10G fiber connections, plus the cost of fiber itself -- it's way more expensive than a 100mbit connection. That said, we do use SFP+ based 10G for our varnish layer -- the amount of traffic pushed by those boxes compared to the amount it would cost to buy a bunch of additional machines makes the extra cost of the interfaces (and don't forget the switch ports! 10G switches cost more than 100mbit switches) make perfect financial sense. Leslie PS - someone technical may point out that DAC (which is copper! gasp!) is cheaper than two SFP+'s and a fiber cable. That's true! However we have had major issues with DAC compatibility on the switch side, and some issues on the hardware side. SFP+'s rarely (albeit occasionally) have that issue. Plus we can keep a spare inventory that is usable in multiple places, making our sparing easier and life easier on the DC techs when we need to scramble for an unexpected 10G need.
