I just got one of these yesterday. It had no trouble working with the "Ubiquiti" Fiberstore SR SFP+ transceiver that I plugged into it. I have it paired with a US-16-XG for more RJ45 ports.
I plan on actually putting it to use on July 22nd when I host my next LAN. I can't wait for my players' machines to be the bottleneck of my download setup. I didn't see any aggregation settings in the control panel for the switch. I expect 10 guests including me so 10Gb should do just fine for now. I wonder if the switch is even capable of LACP. If not, for $150 it's not a big deal.
