Matches growth with the capacity to optimize the investment.
N+2
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)
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.
PUE
total facility power used/total consumed power by IT equipment
Carbon Usage Effectiveness (CUE)
a ratio of the total carbon emissions due to the total energy consumption of the data center compared to
the energy consumption of the data center's servers and IT equipment.
Water Usage Effectiveness (WUE)
a ratio of the annual water usage to how much energy is being consumed by the IT equipment and servers,
and is expressed in liters/ kilowatt-hour (L/kWh).
2 AWG
gauge of wire should be used inside the facility to bound the equipment to the ground
National Fire Protection Association
The organization OSHA ask for help to create workplace electrical safety standards
Overage
can be the result of long-term problems that create swells, or, overvoltage can be thought of as an
extended swell. Overvoltage’s are also common in areas where supply transformer tap settings are set
incorrectly and loads were reduced.
Underage
result from long-term problems that create sags. The term "brownout" describes this problem and has
been superseded by the term "undervoltage." Brownout is ambiguous in that it also refers to commercial
power delivery strategy during periods of extended high demand. Undervoltage can create overheating
in motors and lead to the failure of non-linear loads such as computer power supplies.
Power Spike
occurs when the power level rises above normal levels and then drops back to normal in less than one
second.

Power Surge
occurs when the power level rises above normal levels and stays there for more than one or two seconds.
Power Quality
problems generally indicate that stray frequencies have entered the power system through bad cords or
loose connections.
Red Cable
cable used in the upstream path
Humidity and temperature
The two metrics the HVAC system is controlling in a facility.
Ethernet
Recommended
The conditions are narrower, and represent the target conditions at which the hardware environment
should be maintained for optimal reliability and performance.
Allowable Specifications
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
What two metrics is the HVAC system trying to control in a facility?
Conductive anodic filament (CAF) Formation
is a well-studied phenomenon driven by chemical, humidity, voltage, and mechanical means.
Letent heat of fusion
The amount of heat to melt ice.
Cold Liquid HVAC
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
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
