Computer Room Preparation
The following guidelines are recommended when preparing a computer room for installation of an HP 9000
rp4410 or HP 9000 rp4440 server:
•
Locate the computer room away from the exterior walls of the building to avoid the heat gain from
windows and exterior wall surfaces
•
When exterior windows are unavoidable, use windows that are double- or triple-glazed and shaded to
prevent direct sunlight from entering the computer room
•
Maintain the computer room at a positive pressure relative to surrounding spaces
•
Use a vapor barrier installed around the entire computer room envelope to restrain moisture migration
•
Caulk and vapor seal all pipes and cables that penetrate the envelope
•
Use at least a 12-inch raised floor system for minimum favorable room air distribution system (underfloor
distribution)
•
Ensure a minimum clearance of 12 inches between the top of the server cabinet and the ceiling to allow
for return air flow and ensure that all ceiling tiles are in place
•
Allow 18 inches (or local code minimum clearance) from the top of the server cabinet to the fire sprinkler
heads
