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.
