General computer room requirements

The goal of a computer room is to maintain an ideal environment for

computer equipment, including XP disk arrays.

Make sure your computer room adheres to all national and local building

codes for a data center/computer room environment.

HP recommends that you follow these general guidelines:

• Locate the computer room away from 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 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 introduction of contaminants.

• Install a vapor barrier around the entire computer room envelope

(floors/walls/ceiling) to help keep moisture out of the room. This is

especially important if your computer room is located underground.

• Caulk and vapor-seal all pipes and cables that penetrate the computer

room envelope.

Electrostatic discharge (ESD) can cause component damage, especially

during servicing operations.

Static charges occur when objects are separated or rubbed together. The

voltage level of a static charge is determined by the following factors:

• Types of materials

• Relative humidity — low humidity tends to increase ESD voltage.

• Rate of change — a standard air conditioner cools the air and lowers

humidity. The faster the air is cooled and dried, the greater the

likelihood of ESD.
