I've tried for the longest time to keep storage on a workstation to reduce costs, but in the long run it has really cost me a lot more time and headaches than I'd like to deal with. Presently I only have a 1 Gb CAT6 network. I'd like to build this out to a 10 Gb over ethernet network that at least supports at minimum 2 workstations and 1 server with 10 Gb over CAT6 and the rest with gigabit. The more 10Gb ports the merrier, but I can't break the bank. The machines that would be 10 Gb would be an older 2010 Mac Pro, a newer Hackintosh system, and a FreeBSD server that I'll be offloading the storage to. I'm looking to do this as affordably as possible and was hoping that I could get some input. Any suggestions as far as the switch and network cards go that would work on older Mac Pros? So far I'm hitting a lot of mixed information and I'd like to keep this as simple and clean as possible with the ability to expand.
