Facility planning for implementation 31

• Secondary plumbing requires pipe hangers capable of supporting the following weights:

o 6 foot supply line piping, including water-filled pipes and hoses weighing 143.35 kg (315.37 lbs)

o 6 foot return line piping, including water-filled pipes and hoses weighing 96.37 kg (212.02 lbs)

The rack supply leg must have additional support from a clevis hanger. Facility water hoses may require

additional support.

• The appropriate plumbing kits must be ordered for each HP Apollo f8000 Rack and iCDU to be

installed. For more information, see "Plumbing considerations (on page 24)."

• The facility must be able to accommodate a fluid drain system that connects the iCDU and HP Apollo

f8000 Rack drains to the facility drain system.

For specific information on facility water and secondary loop water requirements, see "Coolant requirements

(on page 31)."

Coolant requirements

General thermal requirements

The table below lists the coolant requirements that the facility must meet in order to support an HP Apollo

8000 System installation. In addition to the requirements listed, the coolant must meet the requirements

prescribed in the section "Water quality requirements (on page 31)."

Facility cooling capacity

(Performance is affected by water temperature)

320 kW maximum per four rack

configuration (80 kW per rack)

The HP Apollo 8000 System can adequately handle the heat load capacity if the facility water temperature

range is 4°C (39°F) to 27°C (80°F) and the minimum facility water differential pressure is 20 psid.

The temperature of the primary cooling water leaving the CDU is normally 35°C (95°F) to 40°C (104°F) with

inlet primary water of 20°C (68°F) to 27°C (80°F).

The primary flow can be calculated based on the facility inlet water temperature. Maximum load is 150 gpm

per CDU at 320 kW. This is based on 25°C (77°F) in and 35°C (95°F) out. Most facilities will have much

lower flow rates, as flow decreases and primary outlet temperature increases as the primary inlet temperature

and rack load decreases. A typical data center with 21°C (70°F) primary water inlet temperature will be less

than 80 gpm per 320 kW heat load.
