I currently have the switches, DB server, fiber cable, ConnectX-2 & ConnectX-3, and the finisar (6 total) transceivers. The other equipment, and in general I want to make sure I have all the right "connection" pieces for this project to go smooth as possible. I've linked to the items for sale, or info... it doesn't mean these are the cheapest prices though!! So those reading later --- google.
Connection Plan from start to end-point:
-...
Netgear XS712T <--> LB4M <--> DB Server
