<p><span style="color:black">Is there such a thing as a 10G SFP+ module that has an RJ45 socket instead of fiber? Not a direct copper link but for cat6/6e/7 ethernet cable.<o:p></o:p></span></p>
<p><span style="color:black">Looking at a few 10G switches and Netgear has a 12 port 10G with rj45 that way affordable but my existing gear all uses sfp+ lc fiber.<o:p></o:p></span></p>
<p><span style="color:black">The new NetworkManager in centos 7 support link aggregation directly with very cool failover and high bandwidth methods that are supportable in the switching I'm looking at from supermicro (24 port 10G all sfp+ for under $6k).<o:p></o:p></span></p>
