v
Where
rack
cabinets
are
in
rows,
each
rack
cabinet
must
touch
the
rack
cabinet
that
is
next
to
it.
This
reduces
the
amount
of
hot
air
that
can
flow
around
from
the
back
of
the
rack
into
the
intakes
of
the
storage
subsystems
that
are
in
that
rack
cabinet.
You
should
use
Suite
Attach
Kits
to
completely
seal
any
gaps
that
remain
between
the
rack
cabinets.
For
details
about
Suite
Attach
Kits,
contact
your
marketing
representative.
v
Where
rack
cabinets
are
in
rows
front-to-front
or
back-to-back,
a
gap
of
at
least
1220
mm
(48
in.)
must
separate
the
rows
across
the
cold
aisle.
v
To
ensure
correct
airflow
in
each
rack
cabinet,
the
rack
filler
plates
must
be
installed
in
unused
positions.
Also,
all
the
gaps
in
the
front
of
the
rack
cabinets
must
be
sealed,
including
the
gaps
between
the
storage
subsystems.
Preparing
for
installation
Before
installing
the
DS4800
Storage
Subsystem,
create
a
detailed
plan
of

in
your
storage
configuration.
The
plan
should
include
determining
RAID
levels,
failover
requirements,
operating
systems
to
be
used,
and
total
storage
capacity
requirements.
Complete
the
following
steps
to
prepare
the
DS4800
for
installation
into
a
rack
cabinet:
1.
Prepare
the
site
to
meet
all
area,
environmental,
power,
