Power Consumption and Cooling Requirements
The power and cooling requirements for the library depend on the number
and type of drives installed. The following table provides the maximum
power consumption and heat load for the base library and for each
additional component added to the base library. 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.
