I've been looking for a 10GBaseT SFP+ module and I found forum posts that are a few years old, like 2011-2013 era. Now that it's 2015, are there any 10GBaseT SFP+ modules that could be put in one of two 10G expansions sleds for 3750x or 3560x, or any other SFP+ capable Cisco switch yet?
Reason I ask is because I am looking at a Dell FX2 chassis server which can hold 8 'blade' servers in 2U of rack space. In the back there are two different I/O agrigators for networking, one is 4 10gbe SFP+ ports (FN410S), and another is 4 100/1000/10000 auto sensing Cat5e/6a RJ-45 interfaces (FN410T).
If I get the RJ-45 interface I/O module the benefit is auto-sensing so I could still link up to a standard 1gbps switch port, and grow into 10gbe-t.
If I get the SFP+ I/O module for this server, well then I am limited to 10gig twinax or fiber SFP+ modules.
