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

. 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-way cabinet. For PA-
8700, the typical power dissipation is approximately 23,660 BTUs/hour for a fully populated 32-way cabinet.

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 room upgrades for
high heat loads. It is based on Liebert's TeleCool product, which has been installed in 600 telecommunications equipment
rooms throughout the world. The system utilizes heat exchanger pump units to distribute fluid in a closed system through
patented cooling coils throughout the data center. The overhead cooling coils are highly efficient heat exchangers with
blowers that direct the cooling where required. The blowers are adjustable to allow flexibility for changing equipment
placement or room configurations. Equipment is protected from possible leaks in the cooling coils by the patented
monitoring system and purge function that detects any leak and safely purges all fluid from the affected coils. DataCool
has interleaved cooling coils to enable the system to withstand a single point of failure and maintain cooling capability.

HP has entered into an agreement with Liebert to reference sell the DataCool solution.
The HP/Liebert business relationship will be managed by HP Complementary Products Division.
DataCool will be reference by HP. Installation, service and support will be performed by Liebert.
HP will compensate the HP Sales Representative and District Manager for each DataCool that Liebert sells to a
customer referred by HP.
An HP/Liebert DataCool website will be setup to get more information on the product and to manage the reference
sales process. Please go to
