Windows
Avoid housing computers in a room with windows. Sunlight entering a computer room may
cause problems. Magnetic tape storage media is damaged if exposed to direct sunlight. Also, the
heat generated by sunlight places an additional load on the cooling system.
Space Requirements
This section contains information about space requirements for an hp server. This data should
be used as the basic guideline for space plan developments. Other factors, such as airflow, lighting,
and equipment space requirements must also be considered.
Delivery Space Requirements
There should be enough clearance to move equipment safely from the receiving area to the
computer room. Permanent obstructions, such as pillars or narrow doorways, can cause equipment
damage.
Delivery plans should include the possible removal of walls or doors.
Operational Space Requirements
Other factors must be considered along with the basic equipment dimensions. Reduced airflow
around equipment causes overheating, which can lead to equipment failure. Therefore, the
location and orientation of air conditioning ducts, as well as airflow direction, are important.
Obstructions to equipment intake or exhaust airflow must be eliminated.
The locations of lighting fixtures and utility outlets affect servicing operations. Plan equipment
layout to take advantage of lighting and utility outlets. Do not forget to include clearance for
opening and closing equipment doors.
Clearance around the cabinets must be provided for proper cooling airflow through the equipment.
If other equipment is located so that it exhausts heated air near the cooling air intakes of the hp
server cabinets, larger space requirements are needed to keep ambient air intake to the hp server
cabinets within the specified temperature and humidity ranges.
Space planning should also include the possible addition of equipment or other changes in space
requirements. Equipment layout plans should also include provisions for the following:
•
Channels or fixtures used for routing data cables and power cables
• Access to air conditioning ducts, filters, lighting, and electrical power hardware
• Power conditioning equipment
