Space for wiring[edit]

Determine use of raised floor and/or overhead cable trays.

Some rack-to-rack cable organization will be necessary.

Rack Layout[edit]

It is crucial to lay out your racks, shelving, and stand-alone systems with accuracy of a few inches when considering location over raised floor access ports.

You should have a minimum of three feet between rack front and back to allow for opening of doors.

A 6' rack spacing interval is recommended as floor tiles come in 2'x2'.

The location of the wheels and/or feet at the bottom of a rack are critical to being able to lift floor panels.

Space for other necessities[edit]

You will absolutely have to have space for at least one desk with monitor and storage units for copious documentation and spare parts.

Phones and switches[edit]

Place light, power, and fire switches in an easy to reach place

Make sure phone is in easy reach of fire suppression cut off switch, NOT the other way around.


Consider putting "non-computer" assets in separate rooms. You can contain leaks easier, as well as keep service technicians away from servers, increasing security, and reducing the need for supervision.
