Although SFP+ modules are not officially supported, my Aruba s2500 switch recognizes the Ubiquiti UF-RJ45-10G version of this device perfectly. They auto-negotiate a full 10Gb/s connection speed, and file transfers can almost maximize connection speeds, although my cable is close to the 100-foot limit. As expected, they get pretty hot, but it's not that hot, which is a problem. Overall I'm very happy with it.
