Recommended - ANS The conditions are narrower, and represent the target conditions at
which the hardware environment should be maintained for optimal reliability and performance.
Allowable Specifications - ANS Specifications are generally quite varied and define the
maximum limit that the hardware should never exceed. Example, may accommodate warm
temperatures, but that may not be best for the hardware to achieve the most reliable
operation.
Humidity and temperature - ANS What two metrics is the HVAC system trying to control in a
facility?
Conductive anodic filament (CAF) Formation - ANS is a well-studied phenomenon driven by
chemical, humidity, voltage, and mechanical means.
Letent heat of fusion - ANS The amount of heat to melt ice.

, Cold Liquid HVAC - ANS HVAC system is helpful in hot desert climates--taking air that needs to
be cooled into the HVAC unit intake. The intake air goes through stages before it is sent to the
data center.
Downflow Method - ANS The most common airflow path used by CRAC units, a combination
of return air entering the top of the unit and supply air being discharged from the bottom of the
unit.
Discharged Air - ANS air typically empties into a raised floor plenum below the electronic
equipment racks. The air supply pressurizes the raised floor plenum and then exits through cold
tiles, which are perforated floor tiles located next to the rack-mounted equipment.
Up-flow Method - ANS The cold supply air from the unit can be discharged through the
bottom, the front, or through the top. The warmer return air can also be configured to enter the
CRAC unit from the front, the rear, or the top
Direct Expansion - ANS What is the most common air conditioning system used in HVAC?
Infrastructure right-sizing - ANS Matches growth with the capacity to optimize the
investment.
N+2 - ANS If a HVAC system is built where there is one main system and two backup systems
it would fall into which redundancy class?
Power usage effectiveness (PUE) - ANS The ratio of the total amount of power that might be
used by the headend or hub, to the power required for the critical or IT equipment--includes
power used for lighting, cooling systems, power distribution.
