Dell Data Center Site Planning Guide Introduction This Site Planning Guide contains recommendations to help you establish the basic site requirements for proper rack installation in your data center. The information contained herein is intended as Dell's basic recommendations for average users of Dell components in typical situations; it is not exhaustive, may not be suited for all circumstances, and is not a substitute for a careful evaluation by each user of such user's specific needs and circumstances.
Dell Data Center Site Planning Guide Ceiling Clearance Before a recommended ceiling height can be provided, there are several things that first must be considered. First and foremost is compliance with the National Fire Protection Association (NFPA), which provides guidance for adequate clearance around fire detection and suppression devices. Typically this is 46 centimeters (cm) (18 inches [in]) minimum above the top of the rack enclosure. Dell recommends additional clearance of at least 30 cm (12 in).
Dell Data Center Site Planning Guide Cooling Requirements Consideration should be given to the intended method of cooling the equipment to be deployed in the rack, understanding the equipment’s specifications, chilled air mass demand, air flow protocol, and installation orientation in the rack to ensure that the air flow protocol aligns with the facility design for the separation of hot from cold.
Dell Data Center Site Planning Guide Re-provision air where a higher demand exists. There are numerous types of vent tiles with varying resistance to flow. By putting more restrictive tiles or a lesser number of vent tiles in areas where the equipment requirements are lower, greater volumes of chilled air can be rerouted to areas with greater chilled air requirements. Consider implementing containment to provide full separation between hot and cold air.
Dell Data Center Site Planning Guide Ensure that you have the following unloading, receiving, and moving equipment available: A loading dock NOTE: If no loading dock is available, you can add inside delivery service to your order so that your rack can be unloaded. If a loading dock is available but you do not specify inside delivery service, the rack will be delivered only as far as the loading dock.
