Cooling Requirements

The cooling system in Superdome was designed to maintain reliable operation of the system in the
specified environment as shown in the Superdome Specifications Table

Superdome Specifications Table

Superdome Specifications Table. In addition, the system is

designed to provide a redundant cooling (i.e. N+1 fans and blowers) that allows all of the
cooling components to be "hot swapped." The typical power dissipation for the PA-8600 is
28,850 BTUs/hour for a fully populated 32-processor cabinet. For PA 8700, the typical power
dissipation is approximately 23,660 BTUs/hour for a fully populated 32-processor cabinet.

NOTE:

NOTE: For other configurations see "Site Prep Guide 6th Edition", Table 5. For maximum power
dissipation, see Superdome Specifications Table

Superdome was designed to operate in all data center environments with any traditional room
cooling scheme (i.e. raised floor environments) but in some cases where data centers have
previously installed high power density systems, alternative cooling solutions may need to be
explored by the customer. Since no such system has been available previously, HP teamed with
Liebert to develop an innovative data room cooling solution called DataCool. DataCool is a
patented overhead climate system utilizing fluid based cooling coils and localized blowers capable
of cooling heat loads of several hundred watts per square foot. Some of DataCool's highlights are
listed below:
Liebert has filed for several patents on DataCool
DataCool, based on Liebert's TeleCool, is an innovative approach to data room cooling
Liquid cooling heat exchangers provide distributed cooling at the point of use
Delivers even cooling throughout the data center preventing hot spots
Capable of high heat removal rates (500 W per square foot)
Floor space occupied by traditional cooling systems becomes available for revenue generating
equipment.
Enables cooling upgrades when installed in data rooms equipped with raised floor cooling

DataCool is a custom-engineered overhead solution for both new data center construction and for data
