System Requirements Summary
This section summarizes the requirements that must be considered in preparing the site for the
server.
Power Consumption and Air Conditioning
To determine the power consumed and the air conditioning required, follow the guidelines in
Table 2-9 .
NOTE:
When determining power requirements, consider any peripheral equipment that will
be installed during initial installation or as a later update. Refer to the applicable documentation
for such devices to determine the power and airconditioning that is required to support these
devices.
Maximum power is the sum of the worst case power consumption of every subsystem in the box
and should be used to size worst case power consumption. Typical power consumption numbers
are what HP engineers have measured when running power-intensive applications. These are
generally lower than maximum power numbers because all of the subsystems in the box to
simultaneously drawing maximum power for long durations is uncommon.
