I’m going to be purchasing a house soon so I will finally have the opportunity to run networking cables to all of my equipment. I have been researching 10Gb networking and have a few questions.
First off, is it worth the extra expense to get hardware that uses copper and RJ45 connectors, or should I just be looking at switches and NICs that use SFP/+?
It is my understanding that if I went with SFP I would need to use much more expensive copper transceivers to get the RJ45 I am used to, but is there any real downside to just getting optical transceivers and running fiber through the home? The only one I can see is that I lose the option of falling back to the built in 1Gb NIC on the motherboard. However I have Wi-Fi which would get me by until I could get the problem fixed.
If I do go with SFP, are the transceivers specific to a certain model/manufacturer of equipment, or can I use, just as an example, a Dell transceiver with a Cisco switch?
I know for SFP+ direct attach is supported without the need for a transceiver, would that have any benefits over fiber transceivers?
My current plan for the high level structure is going to be
MB8600 Modem -> RT-AC68U -> 10Gbe switch LAN (Wi-Fi APs, client devices, NAS).
Eventually I would like to put a big beefy PC in a closet and use a low power ITX build to just stream Windows VMs as my main clients.
