Notes:
1.
Important:
DS4000
EXP700s
are
not
supported
by
the
DS4800
unless
they
have
been
upgraded
(with
the
DS4000
EXP700
Models
1RU/1RX
Switched-ESM
Option
Upgrade
Kit)
to
have
the
same
internal
switched
capabilities
as
the
DS4000
EXP710.
2.
The
DS4800
does
not
support
the
attachment
of
storage
expansion
enclosures
operating
at
1
Gbps,
such
as
the
EXP500.
Intermixing
storage
expansion
enclosures
in
the
same
drive
loop
You
can
intermix
EXP810s,
EXP710s,
and
EXP100s.
When
intermixing
EXP810s
with
EXP710s
or
EXP100s
in
the
same
drive
loop,
the
Link
Rate
switch
for
all
storage
expansion
enclosures
in
the
intermixed
drive
loop
must
be
2
Gbps
because
the
EXP710
and
EXP100
only
operate
at
2
Gbps.
There
are
maximum
limits
to
the
number
of
fibre
channel
hard
drives
that
you
can
configure
in
redundant
drive
channel
pairs.
The
maximum
number
of
drives
dictates
a
fixed
number
of
supported
EXP710
or
EXP100
and
EXP810
drive
enclosure
combinations.

the
numbers
of
14-drive

can
combine
for
use
in
a

drive
channel/loop
pair
in
a
DS4800
configuration.

The

that
a

of
112

has
two
RAID

are
identical
and
interchangeable.
The
