HP StorageWorks XP12000 Disk Array Site Preparation Guide

Environmental requirements

The environmental specifications for operating your disk array must be
satisfied before installation.

Altitude

The maximum altitude for disk array operation is 3,000 meters. For
nonoperational or storage situations, the maximum altitude is 4,000 meters.

Air conditioning

Use separate computer room air conditioning duct work. If it is not separate
from the rest of the building, it might be difficult to control cooling and air
pressure levels. Duct work seals are important for maintaining a balanced
air conditioning system and high static air pressure. Adequate cooling
capacity means little if the direction humidity levels increase when the
ducts are exposed to warm air, producing condensation. Condensation on
any disk hardware can damage the components.

Any questions regarding the adequacy of airflow construction should be
referred to and evaluated by a qualified structural engineer.
