enclosure
configurations
and
intermix
combinations
Although
the
DS4300
Storage
Subsystem
supports
various
types
of
DS4000
storage
expansion
enclosures,
not
all
combinations
of
these
supported
storage
expansion
enclosures
are
possible
or
supported
as
storage
expansion
enclosures
intermixed
within
a
DS4300
Storage
Subsystem
configuration.
In
addition,
if
you
intermix
storage
expansion
enclosures
with
SATA
and
FC
drives
within
a
DS4300
Storage
Subsystem
configuration,
an
FC/SATA
intermix
premium
feature
must
be
purchased
for
that
DS4300
Storage
Subsystem.

is
three
no
matter
what
type
of
storage
expansion
enclosures
used
or
whether
there
is
a
mix
of
14-drive

16-drive
storage
expansion
enclosure
in
the
drive

or
not
when
the
three

was
purchased.
Otherwise,
the
maximum
