Computer or server room location is the first consideration, before even considering the layout of the room’s contents. Most designers agree that, where possible, the computer room should not be built where one of its walls is an exterior wall of the building. Exterior walls can often be quite damp and can contain water pipes that could burst and drench the equipment. Certainly avoid exterior windows that will not only be a security risk, but also be susceptible to breakages. Also, try to avoid both the top floors and basements that may be prone to flooding or leaks in the case of roofs. If a centralised computer room is not feasible, server closets on each floor may be an option. This is where computer, network and phone equipment are housed in closets and each closet is stacked above each other on the floor that they service.
