v Integrated network support The server comes with an integrated Broadcom Gigabit Ethernet controller, which supports connection to a 10-Mbps, 100-Mbps, or 1000-Mbps network. For more information, see "Configuring the Gigabit Ethernet controller" on page 23. v Large data-storage capacity and hot-swap capability The server supports up to four 2.5-inch or two 25.4-mm (1-inch) slim-high, 3.5 inch SCSI 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. This server also supports two 25.4-mm (1-inch) slim-high, 3.5-inch SATA simple swap hard disk drives. v Light path diagnostics Light path diagnostics provides LEDs to help you diagnose problems. For more information, see the section about light path diagnostics in the Installation Guide. v Redundant connection The addition of an optional network interface card (NIC) provides failover capability to a redundant Ethernet connection. If a problem occurs with the primary Ethernet connection, all Ethernet traffic that is associated with the primary connection is automatically switched to the redundant NIC. If the applicable device drivers are installed, this switching occurs without data loss and without user intervention. v Redundant cooling and optional power capabilities The redundant cooling of the fans in the server enables continued operation if one of the fans fails. The server comes with one 585-watt hot-swap power supply. You can order a second optional power supply, which provides redundant power for many server configurations. v ServeRAID™ support The server supports ServeRAID adapters to create redundant array of independent disks (RAID) configurations. v Symmetric multiprocessing (SMP) The server supports up to two Intel 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 a baseboard management controller (BMC) installed. When used with the systems-management software that comes with the server, you can manage the functions of the server locally and remotely. The BMC also provides system monitoring, event recording, and dial-out alert capability. The optional Remote Supervisor Adapter II SlimLine can be used to obtain enhanced system management capabilities, above those of the embedded BMC. The Remote Supervisor Adapter II SlimLine, when installed, has a dedicated Ethernet connection at the rear of the server. Reliability, availability, and serviceability Three important computer 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. Your server has the following RAS features: v Automatic error retry and recovery Chapter 1. Introducing the xSeries 336 Type 8837 server 5

v
Integrated
network
support
The
server
comes
with
an
integrated
Broadcom
Gigabit
Ethernet
controller,
which
supports
connection
to
a
10-Mbps,
100-Mbps,
or
1000-Mbps
network.
For
more
information,
see
“Configuring
the
Gigabit
Ethernet
controller”
on
page
23.
v
Large
data-storage
capacity
and
hot-swap
capability
The
server
supports
up
to
four
2.5-inch
or
two
25.4-mm
(1-inch)
slim-high,
3.5
inch
SCSI
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.
This
server
also
supports
two
25.4-mm
(1-inch)
slim-high,
3.5-inch
SATA
simple
swap
hard
disk
drives.
v
Light
path
diagnostics
Light
path
diagnostics
provides
LEDs
to
help
you
diagnose
problems.
For
more
information,

the
section
about
light
path
diagnostics
in
the
Installation
Guide
.
v
Redundant
connection
The
addition
of
an
optional
network
interface
card
(NIC)
provides
failover
capability
to
a
redundant
Ethernet
connection.
If
a
problem
occurs
with
the
primary
Ethernet
connection,
all
Ethernet
traffic
that
is
associated
with
the
primary
connection
is
automatically
switched
to
the
redundant
NIC.
If
the
applicable
device
drivers
are
installed,
this
switching
occurs
without
data
loss
and
without
user
intervention.
v
Redundant
cooling
and
optional
power
capabilities
The
redundant
cooling
of
the
fans
in
the
server
enables
continued
operation
if
one
of
the
fans
fails.
The
server
comes
with
one
585-watt
hot-swap
power
supply.
You
can
order
a
second
optional
power
supply,
which
provides
redundant
power
for
many
server
configurations.
v
ServeRAID
™
support

server
supports
ServeRAID
adapters
to
create
redundant
array
of
independent
disks
(RAID)
configurations.
v
Symmetric
multiprocessing
(SMP)
The
server
supports
up
to
two
Intel
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
a
baseboard
management
controller
(BMC)
installed.
When
used
with
the
systems-management
software
that
comes
with
the
server,
you
can
manage
the
functions
of
the
server
locally
and
remotely.
The
BMC
also
provides
system
monitoring,
event
recording,
and
dial-out
alert
capability.
The
optional
Remote
Supervisor
Adapter
II
SlimLine
can
be
used
to
obtain
enhanced
system
management
capabilities,
above
those
of
the
embedded
BMC.
The
Remote
Supervisor
Adapter
II
SlimLine,
when
installed,
has
a
dedicated
Ethernet
connection
at
the
rear
of
the
server.
Reliability,
availability,
and
serviceability
Three
important
computer
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.
Your
