Server Room Design
Factors to be considered Cooling AC Environment Control Flooring Lighting Electrical
I .Server Room Construction
- Specify the room height or the minimum clearance between false ceiling and flooring. Rack height + 1 foot is the minimum requirement.
- Specify the size of the room.
- Specify whether false ceiling is required.If required specify the height clearance. Ideally go for fire proof false Ceiling.
- Specify the minimum door openings.Fire proof door.
- It is highly recommended that the door enter from the Hall. This will be easy for material movement and easy accessible for service providers.
- Specify the use of tile or static free flooring. Specify the Height of false flooring.
- Specify the provision of a access control door to restrict access.
- Specify thickness for all walls.
- AC Ducting provision.
- Smoke detector provision.
II. Server Room Environment Control
- HVAC to provide constant temperature and humidity control in degrees C and the Relative Humidity (RH) based on the standards for active or passive components.
- Specify the minimum number of air changes per hour, and spec Positive Pressure to reduce dust.
- Calculate the cooling in cubic meters per hour of 12 C cool air based on the number of 20 A circuits. You may also want to calculate the expected equipment BTU output.
- Intake and exhaust of HVAC at 2.6m above finished floor (AFF)
- Need for a secondary cooling system and/or temperature alarm system. NOTE air conditioning systems will freeze in the winter if it is cold enough.
III. Server Room Fire Suppression Concerns
- wire cage over sprinkler heads
- Dry system or wet system with drainage trough to avoid leaks and condensation damage
- Two coats fire retardant white paint on walls and /or drywall
- Fire proof doors, conduit , false ceiling , flooring.
IV. Flooding
- Location to be high and dry or racks curbed to prevent flood damage
- Avoid penetration through ceiling on serer room.
- Dont plan any water sources above the server room
V. Server Room Lighting
- Specify the Min Ft candles @ 1 meter AFF as per the bicsi standard
- Specify fixture locations
- Specify minimum lighting height above finished floor
- Specify Emergency lighting
- Dont plan the lights straight above the racks.
VI. Electrical
- Specify the power requirement of the servers
- Specify the power panel for the room
- Dont provide switches on power sockets.
- Provide different color sockets for raw and UPS power supply.
- Grounding All equipment and cables grounded
- Floor grounding if anti-static selected
- Separate convenience electrical for power tools at set intervals around room
- Data power minimum 2 duplex plugs 3 wire 120vac, additional as per spec and room expectations
- Specify 240 VAC as required
- Separate power for AC unit? or potential AC unit
- Specify the requirement of UPS /Genset
VII. Controlled special purpose space
- Telecommunication rooms are recommended to be dedicated to the function. Unrelated equipment prohibited, this includes ductwork, piping, and building electrical
VIII. Tray system
1. Cable tray
