administer
your
servers
and
clients
through
remote
problem
notification
as
well
as
monitoring
and
alerting.
v
Integrated
network
support
The
server
comes
with
two
integrated
Broadcom
Gigabit
Ethernet
controllers,
which
support
connection
to
a
10-Mbps,
100-Mbps,
or
1000-Mbps
network.
For
more
information,

v
Large
data-storage
and
hot-swap
capability
The
server
supports
up
to
eight
or
twelve
2.5-inch
hot-swap
hard
disk
drives
in
the
hot-swap
bays
(depending
on
the
model
and
optional
devices
installed).
With
the
hot-swap
feature,
you
can
add,
remove,
or
replace
hard
disk
drives
without
turning
off
the
server.
v
EasyLED
diagnostics
EasyLED
diagnostics
provides
LEDs
to
help
you
diagnose
problems.

v
Memory
mirroring
Memory
mirroring
improves
the
availability
of
memory
by
writing
information
to
the
main
memory
and
redundant
locations
in
a
mirrored
pair
of
DIMMs.
v
Large
system-memory
capacity
The
memory
bus
supports
up
to
128
GB
of
system
memory.
The
memory
controller
supports
error
correcting
code
(ECC)
for
up
to
16
industry-standard
PC3-10600R-999
(single-rank
or
dual-rank),
800,
1067,
and
1333
MHz,
DDR3
(third-generation
double-data-rate),
registered,
synchronous
dynamic
random
access
memory
(SDRAM)
dual
inline
memory
modules
(DIMMs).
v
PCI
adapter
capabilities
The
server
supports
up
to
four
PCI
interface
slots.
For
more
information,

v
Redundant
connection
The
addition
of
the
optional
Ethernet
daughter
card
provides
failover
capability
to
a
redundant
Ethernet
connection
with
the
applicable
application
installed.
If
a
problem
occurs
with
the
primary
Ethernet
connection
and
the
optional
Ethernet
daughter
card
is
installed
on
the
server,
all
Ethernet
traffic
that
is
associated
with
the
primary
connection
is
automatically
switched
to
the
optional
redundant
Ethernet
daughter
card
connection.
If
the
applicable
device
drivers
are
installed,
this
switching
occurs
without
data
loss
and
without
user
intervention.
v
Redundant
cooling
and
power
capabilities
The
server
supports
three
hot-swap
fans,
which
provide
redundant
cooling.
Redundant
cooling
enables
continued
operation
if
one
of
the
fans
fails.
The
server
supports
up
to
two
675-watt
ac
power
supplies,
which
provide
redundancy
and
hot-swap
capability
for
a
typical
configuration.
If
the
maximum
load
on
the
server
is
less
than
675
watts
and
a
problem
occurs
with
one
of
the
power
supplies,
the
other
power
supply
can
meet
the
power
requirements.
v
RAID
support
The
server
supports
an
internal
RAID
SAS
Controller,
which
is
required
for
you
to
use
the
hot-swap
hard
disk
drives
and
to
create
redundant
array
of
independent
disks
(RAID)
configurations.
v
TCP/IP
offload
engine
(TOE)
support
The
Ethernet
controllers
in
the
server
support
TOE,
which
is
a
technology
that
offloads
the
TCP/IP
flow
from
the
microprocessors
and
I/O
subsystem
to
increase
the
speed
of
the
TCP/IP
flow.
When
an
operating
system
that
supports
TOE
is
