Cache
memory
and
RAID
controller
battery
Each
RAID
controller
contains
256
MB
of
cache
memory.
It
also
contains
a
sealed,
rechargeable
lithium
ion
battery
that
maintains
data
in
the
cache
in
the
event
of
a
power
failure.
This
battery
provides
cache
backup
for
up
to
three
days
in
the
event
of
a
power
loss.
The
service
life
of
the
battery
is
36
months,
after
which
time
the
battery
must
be
replaced.
For
information
about
replacing
the
battery,

“Replacing
the
cache
battery
in
the
RAID
controller”
