Upgrading
controllers
The
IBM
System
Storage
DS4800
Controller
Cache
Upgrade
Kit
enables
you
to
upgrade
the
DS4800
controller
memory
cache
either
in
the
DS4800
storage
subsystem
models
82A/H
to
4
GB
of
memory
cache
per
controller
or
in
the
DS4800
storage
subsystem
models
82A/H
and
84A/H
to
8
GB
of
cache
memory
per
controller.
There
are
three
DS4800
controller
cache
upgrade
options
that
are
available
from
IBM:
v
DS4800
Model
82A/H
Cache
upgrade
to
8
GB.
This
option
upgrades
the
DS4800
controllers
with
2
GB
of
cache
memory
per
controller
to
DS4800
controllers
with
4
GB
of
cache
memory
per
controller.
v
DS4800
Model
82A/H
Cache
upgrade
to
16
GB.
This
option
upgrades
the
DS4800
controllers
with
2
GB
of
cache
memory
per
controller
to
DS4800
controllers
with
8
GB
of
cache
memory
per
controller.
v
DS4800
Model
84A/H
Cache
upgrade
to
16
GB.
This
option
upgrades
the
DS4800
controllers
with
4
GB
of
cache
memory
per
controller
to
DS4800
controllers
with
8
GB
of
cache
memory
per
controller.
Important:
v
The
machine
type
and
model
for
the
DS4800
are
printed
on
the
product
label
affixed
to
the
DS4800
storage
subsystem
chassis.
As
a
result,
the
label
that
identifies
this
information
does
not
change
when
you
perform
a
DS4800
controller
upgrade.
However,
after
you
upgrade
the
controller
cache,
the
DS4800
storage
subsystem
functions
as
and
is
treated
as
the
DS4800
model
with
the
cache
memory
to
which
you
have
upgraded.
If
you
perform
a
future
controller
replacement,
ensure
that
you
identify
the
correct
controller
part
number
for
your
DS4800
and
mention
that
you
have
previously
upgraded
the
DS4800
storage
subsystem
controllers.
v
Whenever
you
add
options
to
your
DS4800
storage
subsystem,
be
sure
to
update
the
MAC
information
in
Attention:
Do
not
dispose
of
the
DS4800
controller
CRUs
that
you
replace
with
the
controller
CRUs
in
this
upgrade
kit.
If
separate
return
processing
instructions
for
the
DS4800
controller
CRUs
you
replace
are
included
with
this
upgrade
kit,
follow
the
instructions
to
return
the
replaced
controllers.
