Frequently asked questions
Answer
The cooling capacity of the heat exchanger unit depends on the water
supply temperature and the server inlet set point. The HPE Adaptive
Rack Cooling System can cool rack-mounted components consuming
up to 150 kW of electrical power.
No. All IT equipment that uses the front-to-back cooling system can be
used without restriction in conjunction with the HPE Adaptive Rack
Cooling System.
The HPE Adaptive Rack Cooling System and IT racks are sealed as
much as possible to contain the IT heat load. There could be some
heat passed to the room through conduction of the system panels or
any gaps in between panels that are not fully sealed.
Yes, the control system automatically adjusts the water flow and air
flow to maintain IT inlet temperature set points and supply the proper
volume of air required by the system. IT heat is removed to the facility
water loop.
Water is connected to the unit using a 2-inch flexible hose with cam
and groove fittings.
HPE recommends using the HPE ARCS Water Hookup Kit, part
number P00675-B21.
Yes, the HPE Adaptive Rack Cooling System can operate with doors
open. However, there might be some air exchange with the room and
associated heat load to the room.
CAUTION: Opening both the front and rear doors at the same
time may compromise cooling capacity.
No, assuming that the water quality is maintained, the HPE Adaptive
Rack Cooling System is maintenance-free.
During normal operation some condensation might form, but the HPE
Adaptive Rack Cooling System condensation control system ensures
that the condensation does not reach any rack-mounted components.
Condensation is collected inside the HPE Adaptive Rack Cooling
System unit on the drift eliminator and gathered in the condensation
pan for draining to facility drains.
