Thanks tman222!
I think that's a good idea. FS actually has the custom option there to select chelsio compatibility.
@Derelict
I appreciate your thoughts on the matter.
In my experience, fiber has it's own set of reliability issues (physically weak, requires careful handling, no pinching/bending/pulling, dust and debris can quickly ruin a connection.)
Not saying that it's worse than a custom DAC or CAT 6/7 solution for patching, but I'm just not convinced it's absolutely superior either. I'll think about it. I think I like the elegance of a custom DAC, especially when FS can make them for so cheap anyway... If the system changes at a later date, I don't mind the DACs being throwaways if they served their purpose.
At least one of the 10G connections out of the pfsense box needs to be a 10GBaseT to go to the Intel 10G integrated on the motherboard of the SIEM appliance, so in some ways I'm a bit married to some copper here.
