As someone who doesn't work in a datacenter, is the rackmount absolutely necessary? Apple offers the Mac Pro in a server configuration.
Yes. Rack-mounting 2U Servers in a 42U cabinet means I can fit 16 comfortably with room to breathe, plus have my cable management solution, and room for a Power Distribution device.
Trying to shoehorn server towers into the same rack means I can fit 6 servers, with each pair sitting on a heavy-duty shelf. My cable management is screwed because I'm putting power, data, and control all bundled together up both sides of the rack, and if I need to perform hardware replacement/addition/maintenance, the server has to be removed, surgery done, and then hauled back into place.
Let's not forget the whole density thing - if I can fit 6 quad-CPU xServes in one cabinet, or 16 quad-CPU PowerEdge Servers, which one gives me the best bang for my (ridiculously expensive) pay-by-the-square-foot-per-month footprint dollar?
As English is not my native language, may I correct you English?
How about I correct both? Since Utopia is an ideal of a place, and a proper noun as such: It must be Utopia! Alternatively: It must be Utahpia!
