What
your
server
offers
The
server
uses
the
following
features
and
technologies:
v
Active
PCI-X
(hot-plug)
adapter
capabilities
The
server
has
six
hot-plug
slots
for
peripheral
component
interconnect
(PCI-X)
adapters.
With
operating-system
support,
you
can
replace
a
failing
hot-plug
PCI-X
adapter
without
turning
off
the
server.
If
the
operating
system
and
adapter
support
the
hot-add
feature,
you
can
also
add
a
PCI
adapter
in
one
of
these
slots
without
turning
off
the
server.
v
Baseboard
management
controller
The
baseboard
management
controller
provides
environmental
monitoring
for
the
server.
If
environmental
conditions
exceed
thresholds
or
if
system
components
fail,
the
baseboard
management
controller
lights
LEDs
to
help
you
diagnose
the
problem
and
records
the
errors
in
the
error
log.
The
baseboard
management
controller
is
also
known
as
the
service
processor.
The
baseboard
management
controller
also
provides
remote
server
management
capabilities
through
the
OSA
SMBridge
management
utility
program.
v
IBM
Director
IBM
Director
is
a
workgroup-hardware-management
tool
that
you
can
use
to
centrally
manage
IBM
System
x
and
xSeries
®
servers.
For
more
information,
see
the
IBM
Director
documentation
on
the
IBM
Director
CD.
v
IBM
Enterprise
X-Architecture
technology
IBM
X-Architecture
technology
combines
proven,
innovative
IBM
designs
to
make
your
Intel-processor-based
server
powerful,
scalable,
and
reliable.

Active
™
Memory
The
Active
Memory
feature
improves
the
reliability
of
memory
through
memory
mirroring,
memory
scrubbing,
and
the
Memory
ProteXion
™
feature.
–
Large
system-memory
capacity
The
server
supports
up
to
64
GB
of
system
memory.
The
memory
controller
supports
error
correcting
code
(ECC)
for
up
to
16
industry-standard
PC2-3200,
333
megahertz
(MHz),
1.8
V,
240-pin,
registered,
double-data-rate
(DDR)
II,
synchronous
dynamic
random
access
memory
(SDRAM)
dual
inline
memory
modules
(DIMMs).
–
Memory
ProteXion
The
Memory
ProteXion
feature
provides
the
equivalent
of
a
hot-spare
drive
in
a
RAID
array.
It
is
based
in
the
memory
controller,
and
it
enables
the
server
to
sense
when
a
chip
on
a
DIMM
has
failed
and
to
route
the
data
around
the
failed
chip.
v
IBM
ServerGuide
™
Setup
and
Installation
CD
The
ServerGuide
Setup
and
Installation
CD
that
comes
with
the
server
(standard
on
some
models
only)
provides
programs
to
help
you
set
up
the
server
and
install
a
32-bit
Windows
operating
system.
The
ServerGuide
program
detects
installed
hardware
options
and
provides
the
correct
configuration
programs
and
device
drivers.
For
more
information
about
the
ServerGuide
Setup
and
Installation
CD,

“Using
the
ServerGuide

and
Installation
CD”
