IBM xSeries 235 User Manual
What
your
server
offers
The
design
of
your
server
takes
advantage
of
advancements
in
symmetric
multiprocessing
(SMP),
data
storage,
disk-array
technologies,
and
memory
management.
Your
server
combines:
v
IBM
X-Architecture
technology
IBM
X-Architecture
features
leverage
proven
innovative
IBM
technologies
to
build
the
most
powerful,
scalable,
reliable
Intel-processor-based
servers
in
the
world.
X-Architecture
features
include
Light
Path
Diagnostics,
Chipkill
™
memory,
Predictive
Failure
Analysis
(PFA),
and
the
Advanced
System
Management
processor.
v
Impressive
performance
using
SMP
Your
server
supports
up
to
two
Intel
Xeon
microprocessors.
Your
server
comes
with
at
least
one
microprocessor
installed;
if
it
comes
with
one
microprocessor,
you
can
install
an
additional
microprocessor
to
enhance
performance
and
provide
SMP
capability.
v
Large
data-storage
and
hot-swap
capabilities
All
models
of
the
server
support
up
to
six
25.4
mm
(1-inch)
slim-high,
3.5-inch
hot-swap
hard
disk
drives
in
the
hot-swap
bays.
This
hot-swap
feature
enables
you
to
add,
remove,
or
replace
hard
disk
drives
without
turning
off
the
server.
v
Active
PCI
(hot-plug)
adapter
capabilities
Your
server
has
two
hot-plug
slots
for
peripheral
component
interconnect
(PCI)
adapters.
With
operating
system
support,
you
can
replace
failing
hot-plug
PCI
adapters
without
turning
off
the
server.
You
can
also
add
PCI
adapters
in
these
slots
without
turning
off
the
server,
if
the
operating
system
and
the
adapter
support
the
hot-add
feature.
v
Redundant
cooling
and
power
capabilities
The
redundant
cooling
and
hot-swap
capabilities
of
the
fans
in
your
server
enable
continued
operation
if
one
of
the
fans
fails.
You
can
also
replace
a
failing
fan
without
turning
off
the
server.
Some
models
of
the
server
come
with
two
hot-swap
560-watt
power
supplies.
The
two
hot-swap
power
supplies
provide
redundant
power
for
many
server
configurations.
If
a
problem
occurs
with
one
of
the
power
supplies,
the
other
power
supply
can
handle
the
load.
The
NONREDUNDANT
light-emitting
diode
(LED)
on
the
diagnostic
LED
panel
is
lit
when
a
problem
is
detected
with
one
of
the
redundant
hot-swap
power
supplies.
For
models
that
come
with
one
fixed
560-watt
power
supply,
a
hot-swap
power-supply
option
containing
two
hot-swap
560-watt
power
supplies
is
available;
you
can
replace
the
fixed
power
supply
with
the
hot-swap
power-supply
option
to
provide
redundancy.
(See
the
Option
Installation
Guide
on
the
IBM
xSeries
Documentation
CD
for
instructions.)
v
Large
system
memory
Your
server
supports
up
to
6
GB
of
system
memory.
The
memory
controller
provides
error
correcting
code
(ECC)
support
for
up
to
six
industry-standard,
133
MHz/266
MHz,
2.5
V,
184-pin,
double-data-rate
(DDR),
PC2100
registered,
synchronous
dynamic
random-access
memory
(SDRAM)
dual
inline
memory
modules
(DIMMs).
The
memory
controller
also
provides
Chipkill
Memory
protection
if
all
DIMMs
are
of
the
type
x4.
Chipkill
Memory
protection
is
a
technology
that
protects
the
server
from
a
single
chip
failure
on
a
DIMM.
v
System-management
capabilities
Your
server
comes
with
an
integrated
system
management
processor
(ISMP)
and
support
for
the
Remote
Supervisor
Adapter.
The
ISMP,
in
conjunction
with
