v
Redundant
connection
The
addition
of
an
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
optional
power
capabilities
The
server
supports
a
maximum
of
two
675-watt
hot-swap
power
supplies
and
six
hot-swap
fans,
which
provide
redundancy
and
hot-swap
capability
for
a
typical
configuration.
The
redundant
cooling
by
the
fans
in
the
server
enables
continued
operation
if
one
of
the
fans
fails.
The
server
comes
with
one
675-watt
hot-swap
power
supply
and
five
fans.
You
can
order
the
second
optional
power
supply
with
the
additional
fan.
v
RAID
support
The
RAID
adapter
provides
hardware
redundant
array
of
independent
disks
(RAID)
support
to
create
configurations.
The
standard
RAID
adapter
provides
RAID
levels
0,
1,
and
1E.
An
optional
RAID
adapter
is
available
for
purchase
that
provides
RAID
levels
0,
1,
5,
6,
10,
50,
and
60.
v
Systems-management
capabilities
The
servers
comes
with
an
Integrated
Management
Module
(IMM).
When
the
IMM
is
used
with
the
systems-management
software
that
comes
with
the
server,
you
can
manage
the
functions
of
the
server
locally
and
remotely.
The
IMM
also
provides
system
monitoring,
event
recording,
and
network
alert
capability.
The
system-management
connector
provides
additional
security
by
physically
separating
the
management
network
traffic
from
the
production
network.
You
can
use
the
Setup
utility
to
configure
the
server
to
use
a
dedicated
systems-management
network
or
a
shared
network.
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
microprocessor
and
I/O
subsystem
to
increase
the
speed
of
the
TCP/IP
flow.
When
an
operating
system
that
supports
TOE
is
running
on
the
server
and
TOE
is
enabled,
the
server
supports
TOE
operation.
See
the
operating-system
documentation
for
information
about
enabling
TOE.
Note:
The
Linux
operating
system
does
not
support
TOE.
v
Preboot
diagnostics
program
The
preboot
diagnostics
programs
are
stored
on
the
integrated
USB
memory.
They
collect
and
analyze
system
information
to
aid
in
diagnosing
server
problems.
The
diagnostic
programs
collect
the
following
information
about
the
server:
–
System
configuration
–
Network
interfaces
and
settings
–
Installed
hardware
–
EasyLED
status
–
Service
processor
status
and
configuration
–
Vital
product
data,
firmware,
and
UEFI
(formerly
called
BIOS)
configuration
–
Hard
disk
drive
health
–
RAID
controller
configuration
–
Event
logs
for
RAID
controllers
and
service
processors
