Memory
mirroring
stores
data
in
two
pairs
of
DIMMs
simultaneously.
To
support
memory
mirroring,
you
must
install
identical
dual
inline
memory
modules
(DIMMs)
in
all
DIMM
slots.
For
more
information,
see
the
section
about
installing
memory
modules
in
the
Option
Installation
Guide
on
the
IBM

Online-spare

disables
a
failed
DIMM
pair
from
the
system
configuration
and
activates
an
online-spare
memory
DIMM
pair
to
replace
the
failed
pair.
Before
you
can
enable
this
feature,
you
must
install
one
additional
pair
of
DIMMs.
The
online-spare
memory
DIMM
pair
must
be
the
same
speed
and
type,
and
the
same
size
as
the
active
DIMM
pair
or
larger.
Enable
online-spare
memory
through
the
Configuration/Setup
Utility
program.
The
BIOS
assigns
the
online-spare
memory
DIMM
pair
according
to
your
DIMM
configuration.
