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, see "Using the Configuration/Setup Utility program" on page 16. IBM Director With IBM Director, a network administrator can: v View the hardware configuration of remote systems, in detail v Monitor the usage and performance of critical components, such as microprocessors, disks, and memory v Centrally manage individual or large groups of IBM and non-IBM Intel-based servers, desktop computers, workstations, and mobile computers on a variety of platforms IBM Director provides a comprehensive entry-level workgroup hardware manager.

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

information,
see
the
section
about
installing

modules
in
the

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
