Spectra Stack Tape Library - Power Consumption and Cooling

POWER CONSUMPTION AND COOLING
REQUIREMENTS
The power and cooling requirements for the library depend on the number and type
of drives installed and number of library modules. The following table provides the
maximum power consumption and heat load for the base module fully loaded with
half-height and full-height drives and expansion modules fully loaded with half-
height and full-height drives. Use this information to calculate the total maximum
power consumption and heat load values, which can be used to build a power budget
for the library.
All values are measured at the AC input and include power supply efficiency. The
values are averages of observed hardware. In general, the lighter the load on the
power supplies, the less efficient they are. The power supply efficiency in turn affects
the power draw of all components.
