Cooling requirements HP Integrity Superdome 2 is a rack mounted system that cools by drawing air in the front and exhausting it out the rear. General ASHRAE best practices must be followed when installing Superdome 2 in a data center: • Hot/cold aisle layout • Fully blank any unused space in the rack with appropriate blanking panels • Ensure minimal air recirculation by making sure that no gaps exist between adjacent racks • Ensure an adequate hot-air return path to the computer room air conditioners (CRAC) or computer room air handlers (CRAH), which minimizes the flow of hot air over any rack HP Integrity Superdome 2 utilizes variable speed fans to realize the most efficient use of air. The volume of air required varies with the temperature of the air supplied to the inlet of HP Integrity Superdome 2.

Cooling requirements
HP Integrity Superdome 2 is a rack mounted system that cools by drawing air in the front and
exhausting it out the rear. General ASHRAE best practices must be followed when installing
Superdome 2 in a data center:
Hot/cold aisle layout
Fully blank any unused space in the rack with appropriate blanking panels
Ensure minimal air recirculation by making sure that no gaps exist between adjacent racks
Ensure an adequate hot-air return path to the computer room air conditioners (CRAC) or
computer room air handlers (CRAH), which minimizes the flow of hot air over any rack
HP Integrity Superdome 2 utilizes variable speed fans to realize the most efficient use of air. The
volume of air required varies with the temperature of the air supplied to the inlet of HP Integrity
Superdome 2. The following table and chart illustrate the necessary volume of air to enable
proper operation:
