I am about to add 3 new servers into an existing network, which is currently all on 1gbps ethernet. All of the new servers are SSD-based and to me it makes sense to go with 10gbps coming out of the servers into a switch, and then 1gbps out to the workstations. The new server location is about 200 feet from the existing networking equipment/old server location, so using Cat 6A/Cat 7 copper would be REALLY nice/economical. Where I am hitting a jam is any 48 port gigabit + 4 10gbps switch is $$$. I am trying to find a small 10gbps copper switch, say an 8 port, that is expandable, and compatible with a 48 port 1gbps switch. Does such a thing exist?
