We mostly stick with SFP+ based switches and use SFP+ DAC, Active Optical, or fiber, depending upon distance. The switches are a bit cheaper, use less power, and have more connectivity options. But, if you need to leverage your existing copper infrastructure for some reason, then the RJ45 connections are probably your best bet. If you are talking about server room, I'd stick with SFP+. $.02, YMMV
