What
your
server
offers
Your
server
takes
advantage
of
advancements
in
symmetric
multiprocessing
(SMP),
data
storage,
disk-array
technologies,
and
memory
management.
Your
server
includes:
v
IBM
X-Architecture
design
IBM
X-Architecture
technology
combines
proven,
innovative
IBM
designs
to
make
your
Intel-processor-based
server
powerful,
scalable,
and
reliable.
X-Architecture
design
includes
Chipkill
™
memory
(some
models),
hot-swappable
hard
disk
drives,
and
Predictive
Failure
Analysis
®
capability.
v
Impressive
performance
using
SMP
Your
server
supports
up
to
two
Intel
Xeon
microprocessors.
It
comes
with
at
least
one
microprocessor
installed;
if
it
comes
with
only
one
microprocessor,
you
can
install
an
additional
microprocessor
to
enhance
performance
and
provide
SMP
capability.
v
Large
data-storage
and
hot-swap
capabilities
Some
server
models
support
up
to
six
25.4-mm
(1-inch)
slim-high,
3.5-inch
hot-swap
hard
disk
drives
in
the
hot-swap
bays.
With
the
hot-swap
feature,
you
can
add,
remove,
or
replace
hard
disk
drives
without
turning
off
the
server.
v
Redundant
power
capabilities
Some
models
of
the
server
come
with
two
514-watt
hot-swap
power
supplies,
which
provide
redundant
power
for
many
server
configurations.
If
the
average
load
on
your
server
is
less
than
514-watt
and
a
problem
occurs
with
one
of
the
power
supplies,
the
other
power
supply
can
handle
the
load.
v
Large
system
memory
Your
server
supports
up
to
8
GB
of
system
memory.
The
memory
controller
provides
error
correcting
code
(ECC)
support
for
up
to
four
industry-standard,
133
MHz,
2.5
V,
184-pin,
double-data-rate
(DDR),
PC2100
registered,
synchronous
dynamic
random
access
memory
(SDRAM)
dual
inline
memory
modules
(DIMMs).
Your
memory
controller
provides
Chipkill
memory
protection
if
the
DIMMs
are
512
MB
or
larger.
Chipkill
memory
protection
is
also
provided
on
servers
with
256
MB,
128
Mb
technology
DIMMs
installed.
All
128
MB
DIMMs
or
256
MB,
256
Mb
technology
DIMMs
do
not
provide
Chipkill
memory
protection.
Chipkill
memory
protection
is
a
technology
that
protects
the
server
from
a
single
chip
failure
on
a
DIMM.
v
System-management
capabilities
Your
server
supports
an
optional
IBM
Remote
Supervisor
Adapter
II.
By
using
the
optional
IBM
Remote
Supervisor
Adapter
II
with
the
system-management
software
that
comes
with
your
server,
you
can
manage
the
functions
of
the
server
locally
and
remotely
giving
you
a
World
Wide
Web
interface
to
the
system-management
functions.
See
the
documentation
that
comes
with
your
system-management
software
for
more
information.
To
order
an
optional
Remote
Supervisor
Adapter
II
,
contact
your
IBM
marketing
representative
or
authorized
reseller.
v
Integrated
network
environment
support
Your
server
comes
with
an
integrated
Broadcom
Gigabit
Ethernet
controller
on
the
system
board.
This
Ethernet
controller
has
an
interface
for
connecting
to
a
10-Mbps,
100-Mbps,
or
1-Gbps
network.
The
server
automatically
selects
between
10BASE-T
and
100/1000BASE-TX
environments.
The
controller
provides
full-duplex
(FDX)
capability,
which
enables
simultaneous
transmission
and
reception
of
data
on
an
Ethernet
local
area
network
(LAN).
This
controller
supports
Wake
on
LAN
®
technology.
