Memory
mirroring
and
sparing
Memory
mirroring
stores
data
in
memory
pair
1
and
2
and
memory
pair
3
and
4
simultaneously.
To
support
memory
mirroring,
you
must
install
identical
dual
inline
memory
modules
(DIMMs)
in
memory
pair
1
and
2
and
memory
pair
3
and
4.
For
more
information,
see
the
section
about
installing
memory
modules
in
the
Option
Installation
Guide
on
the
IBM
xSeries
Documentation
CD.
The
server
also
supports
memory
sparing;
however,
the
sparing
feature
is
mutually
exclusive
with
mirroring.
The
sparing
feature
disables
the
failed
memory
from
the
system
configuration
and
activates
a
memory
sparing
pair
of
DIMMs
to
replace
the
failed
active
DIMM
pair.
Before
you
can
enable
the
memory
sparing
feature,
you
must
install
one
additional
pair
of
DIMMs.
The
memory
sparing
DIMM
pair
must
be
the
same
speed,
type,
and
the
same
size
as
or
larger,
than
the
active
DIMM
pair.
To
enable
memory
mirroring
or
sparing
through
the
Configuration/Setup
Utility
program,
select
Advanced
Setup
from
the
main
menu,
and
select
Memory
Configuration
.
For
more
information
about
using
the
Configuration/Setup
Utility
program,

“Using
the
Configuration/Setup
Utility
program”
