v
Integrated
network
support
The
server
comes
with
two
integrated
Broadcom
Gigabit
Ethernet
controllers,
which
support
connection
to
a
10
Mbps,
100
Mbps,
or
1
Gbps
network.
For
more
information,
see
“Configuring
the
Gigabit
Ethernet
controllers”
on
page
81.
v
Large
system-memory
capacity
The
memory
bus
in
the
server
is
enabled
for
up
to
48
GB
of
system
memory.
The
memory
controller
supports
error-correcting
code
(ECC)
for
up
to
12
industry-standard
PC2-5300,
1.8
V,
184-pin,
8-byte,
registered,
double-data-rate
2
(DDR2)
synchronous
dynamic
random-access
memory
(SDRAM)
dual
inline
memory
modules
(DIMMs).
The
server
supports
512
MB
(type
x8)
DIMMs
and
the
following
sizes
of
type
x4
DIMMs:
1
GB,
2
GB,
and
4
GB.
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
system
from
a
single
chip
failure
on
a
DIMM.
Note:
Chipkill
memory
protection
is
not
supported
on
512
MB
DIMMs.
In
addition,
the
memory
controller
contains
built-in
technology
that
improves
memory-to-microprocessor
processing
performance.
v
Online-spare
memory
Online-spare
memory
disables
a
failed
pair
of
DIMMs
from
the
system
configuration
and
activates
an
online-spare
DIMM
pair
to
replace
the
failed
pair.
v
Symmetric
multiprocessing
(SMP)
The
server
supports
up
to
two
AMD
Opteron
microprocessors.
If
the
server
comes
with
only
one
microprocessor,
you
can
install
an
additional
microprocessor
to
enhance
performance
and
provide
SMP
capability.
v
Systems-management
capabilities
The
server
comes
with
features
that
a
network
administrator
or
file
server
can
use
to
remotely
manage
and
control
the
server.
Reliability,
availability,
and
serviceability
Three
important
server
design
features
are
reliability,
availability,
and
serviceability
(RAS).
The
RAS
features
help
to
ensure
the
integrity
of
the
data
that
is
stored
in
the
server,
the
availability
of
the
server
when
you
need
it,
and
the
ease
with
which
you
can
diagnose
and
correct
problems.
The
server
has
the
following
RAS
features:
v
Advanced
Configuration
and
Power
Interface
(ACPI)
v
Automatic
restart
after
a
power
failure
v
Basic
input/output
system
(BIOS)
code
boot-block
recovery
v
Chipkill
memory
protection
v
Cooling
fans
with
speed
control
v
Customer
support
center
24
hours
per
day,
7
days
a
week
2
v
Cyclic
redundancy
check
(CRC)
v
Diagnostic
CD
v
Diagnostic
LEDs
on
the
system
board
v
Diagnostic
support
of
Ethernet
adapters
2. Service
availability
will
vary
by
country.
Response
time
will
vary
depending
on
the
number
and
nature
of
incoming
calls.
