While you have no reason to believe that anyone in your company would ever have a reason to mess with your servers, unless you have a way to lock your IT room, you may want to invest in a server cabinet with locking doors. Unlike server racks, you will find that most server cabinets have doors on the front and full side panels.
Make Sure Your New Server Rack Can Breathe
If you are going to put your servers in a server cabinet instead of rack, you need to keep in mind the fact that your servers need to be able to breathe. Access to cooling air is vital for the life of your servers as they tend to generate a remarkable amount of heat, especially when they are under a heavy load. Read the specs very carefully before you order your new cabinet so that you don’t end up burning down one of your servers.
