Run lots of cables, or use a switch?
We've just had a shiny new HP ProCurve 5406zl switch installed in to our current server room comms cabinet, in to which goes our current batch of servers. It's fitted with 14 fibre ports to feed other cabinets around the school in a star topology. During the summer, our server room is moving to an adjacent room after a refurb. However the comms cabinet is staying in the old room (literally next door). It has not been budgeted, or planned that the comms cabinet, with all it's fibre will be moving, so I am debating one of the following options....
1). Run individual ethernet cables from each server, through a hole in the wall, back to the 5406zl switch.
2). Install a Procurve 1800-24G gigabit switch in each of our two server racks, make a 2Gb trunk to each switch from the 5406zl, meaning only running 4 cables which could be put in mini trunking, then having all the server connections accessible at the server racks
I feel i should plug all my important stuff, ie the servers, straight in to our core switch, but for fault finding and tidyness would prefer to go for option number 2! What sort of real world performance hit would you get using option 2 - negligible? What would you do?
