embedded
BMC.
The
Remote
Supervisor
Adapter
II
SlimLine,
provides
a
dedicated
Ethernet
connection
at
the
rear
of
the
server.
v
TCP/IP
offload
engine
(RTOE)
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:
As
of
the
date
of
this
document,
the
Linux
operating
system
does
not
support
TOE.
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
v
Automatic
restart
after
a
power
failure
v
Baseboard
