DS4500
Storage
Server
The
IBM
DS4500
storage
server
provides
dual,
redundant
controllers
with
fibre
channel
interfaces
to
both
the
host
and
drive
loops.
The
DS4500
storage
server
has
redundant
cooling,
redundant
power,
and
battery
backup
of
the
controller
cache.
Designed
to
provide
maximum
host
and
drive-side
redundancy,
the
DS4500
storage
server
supports
direct
attachment
of
up
to
four
hosts
that
contain
two
host
adapters
each.
By
using
external
fibre
channel
managed
hubs
and
switches
in
conjunction
with
the
DS4500
storage
server,
you
can
attach
up
to
64
hosts
with
two
adapters
each
to
a
DS4500
storage
server.
The
DS4500
storage
server
is
compatible
with
the
following
IBM
products:
v
IBM
FAStT
EXP500
(see
Chapter
13
on
page
111)
v
IBM
DS4000
EXP700
and
DS4000
EXP710
The
DS4000
controller
firmware
must
be
upgraded
to
version
05.21.xx.xx
or
later
to
enable
DS4500
storage
server
support
for
the
DS4000
EXP700.
The
DS4000
controller
firmware
must
be
upgraded
to
version
06.11.xx.xx
or
later
to
enable
DS4500
storage
server
support
for
the
DS4000
EXP710.
v
IBM
DS4000
EXP100
The
DS4000
controller
firmware
version
05.41.xx.xx
enables
the
DS4500
storage
server
to
support
the
DS4000
EXP100.
However,
it
is
recommended
that
you
upgrade
the
DS4000
controller
firmware
to
the
latest
version
available
(06.11.xx.xx
or
higher).
Important:
The
DS4500
storage
server
currently
supports
the
concurrent
attachment,
or
intermixing,
of
fibre
channel
and
Serial
ATA
storage
expansion
units
in
a
single
DS4500
storage
server
configuration.
To
enable
FC/SATA
intermixing
with
the
DS4500
storage
server,
you
must
purchase
the
FC/SATA
Intermix
premium
feature
and
perform
the
required
DS4000
Storage
Manager
and
firmware
upgrades
to
support
FC/SATA
intermixing.
