General computer room requirements

Preparing for installation
The purpose of a computer room is to maintain an ideal environment for
your computer equipment, including your HP Disk Array XP128. The
following guidelines are recommended:
• Locate the computer room away from exterior walls of the building to
avoid the heat gain from windows and exterior wall surfaces.
• When locating near exterior windows is unavoidable, use windows
that are double or tripled glazed and shaded to prevent direct sunlight
from entering the computer room.
• Maintain the computer room at a positive pressure relative to the
surrounding spaces to reduce the introduction of contaminants.
• 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 a 10-inch to 12-inch raised floor system for the most favorable
room air distribution system if the under floor area is being used as an
as part of the air circulation system.
Space planning
A site prep begins with your existing floor plan. The location of the new
equipment should be selected and a new floor plan should be developed.
You can use this section to satisfy the disk array physical requirements,
ensuring that your site is ready when the disk array arrives. Your floor plan
should include the location of:
• Walls
• Cable paths, including lengths
• All equipment in your computer room, including furniture, cabinets,
racks, data comm equipment, and systems
• Electrical outlets
• Immovable objects
• Floor vents
