Memory
Requirements
Note:
The
configuration
of
a
system
that
was
ordered
with
memory
Capacity
Upgrade
on
Demand
(CUoD)
features
will
appear
slightly
different
than
the
configuration
in
this
discussion.
When
the
system
is
ordered,
the
installed
memory
is
positioned
according
to
the
following
guidelines:
v
The
pSeries
690
has
eight
memory
slots.
Four
memory
slots
use
inward-facing
memory
cards
and
four
use
outward-facing
memory
cards.
The
inward-facing
memory
slots
are
used
by
the
first
and
second
processor
module
positions,
while
the
outward-facing
memory
slots
support
the
third
and
fourth
8-way
processor
module
positions.
v
A
pSeries
690
system
with
only
one
processor
MCM
position
populated
has
access
to
only
two
inward-facing
memory
slots.
v
Minimum
system
memory
is
8
GB.
Maximum
system
memory
is
512
GB.
v
Memory
is
available
in
4
GB,
8
GB,
16
GB,
32
GB,
and
64
GB
inward-facing
and
outward-facing
increments.
v
The
following
memory
configuration
considerations
are
recommended
to
ensure
the
optimum
performance
is
obtained
for
the
system:
–
Memory
should
be
installed
in
identical
pairs.
–
All
available
memory
locations
should
be
populated
with
memory
cards.
–
Memory
sizes
should
be
balanced
as
closely
as
possible
across
all
populated
MCM
locations.
v
The
number
of
active
memory
book
slots
in
a
system
is
related
to
the
number
of
populated
MCM
locations.
Two
memory
book
slots
are
activated
with
each
MCM
that
is
installed.
–
The
first
MCM
installed
activates
the
first
and
second
inward-facing
memory
positions.
–
The
second
MCM
installed
activates
the
third
and
fourth
inward-facing
memory
positions.
–
The
third
MCM
installed
activates
the
first
and
second
outward-facing
memory
positions.
–
The
fourth
MCM
installed
activates
the
third
and
fourth
outward-facing
memory
positions.
v
It
is
recommended
that
all
systems
have
access
to
a
4-mm
or
8-mm
tape
drive
for
submission
of
system
dump
information,
if
required.
This
function
can
be
accomplished
through
locally
attached
or
network-attached
devices
as
appropriate.
