Therefore, the XP24000 is not suitable in a hot isle containment system. XP20000 cooling airflow has air intake at front and hot air exhaust out the rear. Therefore, the XP20000 is suitable in hot isle containment system. Controlling dust and pollution Airborne contaminants and particles of a certain size and hardness can damage the system. Some of the most common contaminants are dust, smoke, ash, corrosive gases and corrosive particulate. Mechanical filters on the disk array protect it by trapping large dust particles. Smaller particles can pass through most filters, and can eventually cause problems in mechanical parts and electrical contacts. Prevent small dust particles from entering the computer room by maintaining its air conditioning system at a high static air pressure level. Your HP representative can help you determine if you need to be concerned about airborne contaminants including gaseous chemical contaminants. HP strongly recommends your site be evaluated for metallic particulate contamination and gaseous chemical contaminants for sites with suspect air quality concerns. Evaluation should be done before the system is installed and periodically monitored. 36 Site requirements for the HP Disk Arrays
