Thanks for all the help and those who reached out to me off list. I changed the 
10G switch to a Netgear one, everything has been ordered and should start 
arriving tomorrow. Ordering cables was the only setback. Even though Amazon 
would state they had them in stock, when I went to complete the order, every 
cable would show "to be delivered in 1 to 4 weeks". Tried multiple vendors and 
had the same result for all of them. Oh well, I will get everything connected 
to the 10G switch when the cables do show up.

Watch for an updated lab article on my site.

If I break the seal on the server's case, I void the warranty. I have never 
worked with 10GbE before and never thought of adding it to the lab but that 
UBNT 10G switch looked affordable considering the cost of other 10G managed

I’m not a hardware dude, but couldn’t you get a fiber NIC for your server?

Something like this:

With those prices, I will have to rethink the switch I plan to use!!!

It used to be that 10GBASE-T was outside of the SFP+ power envelope but there’s 
a couple of SFP+ modules with 10GBASE-T media now—they work by “modifying” the 
10GBASE-T spec to reduce its power usage. The downside is reduced cable length 
support and what I assume is an absolute ton of heat output.<>

I would be somewhat concerned about running a bunch of those in my switch but 
one or two would probably be fine. You could also look for a standalone media 
converter that takes SFP+ on one end and delivers 10GBASE-T on the other 
side—probably the more expensive but safer solution since it’s full power and 
dumping its heat somewhere that’s not directly into your switch.

I have a SuperMicro server with dual 10GBASE-T ports. I am looking at a 
Ubiquiti UniFi Switch 16 XG. I know that switch has four 10GBASE-T ports but I 
plan on using those for my NAS that has 10GBASE-T ports. Is it possible to 
connect the server's 10GBASE-T ports to an SFP+ port with a specific cable and 
connectors? If so, any recommendations on what to use?
