For
more
information
on
the
Configuration/Setup
Utility
program,
see
When
you
use
online-spare
memory,
you
must
consider
the
following
information:
-
You
cannot
enable
online-spare
memory
while
the
server
is
operating
in
mirroring
mode.
-
The
minimum
memory
configuration
is
two
single-rank
DIMMs
installed
in
branch
0,
DIMM
connector
1
(in
channel
0)
and
connector
4
(in
channel
1);
however,
online-sparing
is
not
supported
with
this
configuration.
-
To
support
online-sparing
in
branch
0,
you
must
add
a
second
pair
of
DIMMs.
The
spare
pair
of
DIMMs
can
be
single-rank
or
double-rank
and
must
be
the
same
speed,
type,
size
(or
larger),
and
technology
as
the
failed
pair
of
DIMMs.
The
spare
pair
must
be
installed
in
branch
0,
DIMM
connector
2
(in
channel
0)
and
connector
5
(in
channel
1).
However,
if
the
DIMMs
are
double-rank
and
you
install
the
spare
pair
of
DIMMs
in
branch
1,
DIMM
connector
7
(channel
2)
and
connector
10
(channel
3)
rather
than
branch
0,
then
branch
1
will
support
online-sparing
and
branch
0
will
not.
-
Branch
0
and
branch
1
operate
independently.
v
The
following
notes
apply
when
the
server
operates
in
non-mirroring
mode
(normal
mode):
–
DIMMs
must
be
installed
in
matched
pairs.
If
you
install
a
second
pair
of
DIMMs
in
DIMM
connector
7
and
DIMM
connector
10,
they
do
not
have
to
be
the
same
size,
speed,
type,
and
technology
as
the
DIMMs
in
DIMM
connector
1
and
DIMM
connector
4.
However,
the
size,
speed,
type,
and
technology
of
the
DIMMs
that
you
install
in
DIMM
connector
7
and
DIMM
connector
10
must
match
each
other.

The
amount
of

the
system
configuration.
A
certain
amount
of
memory
must
be
reserved
for
system
resources.
To
view
the
total
amount
of
installed
memory
and
the
amount
of
configured
memory,
run
the
Configuration/Setup
Utility
program
and
select
System
Summary
from
the
menu.
For
