v Systems-management capabilities The server supports an optional IBM Remote Supervisor Adapter II SlimLine. When you use this adapter, you can manage the functions of the server locally and remotely. The Remote Supervisor Adapter II SlimLine also provides system monitoring, event recording, and dial-out alert capability. 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 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 features 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 repair problems. The server has the following RAS features: v Automatic error retry and recovery v Automatic restart after a power failure v Backup basic input/output system (BIOS) switching under the control of the baseboard management controller v Baseboard management controller (service processor) v Built-in monitoring for fan, power, temperature, voltage, and power-supply redundancy v Cable-presence detection on most connectors v Chipkill memory protection v Error codes and messages v Error correcting code (ECC) L2 cache and system memory v Fully-buffered DIMMs (FBD) support v Hot-swap cooling fans with speed-sensing capability v Hot-swap hard disk drives v Hot-spare memory v Information and light path diagnostics LED panels v Memory mirroring v Menu-driven setup, system configuration, and redundant array of independent disks (RAID) configuration programs v Parity checking or CRC checking on the serially-attached SCSI (SAS) bus and PCI buses v Power management: compliance with Advanced Configuration and Power Interface (ACPI) v Power-on self-test (POST) v Predictive Failure Analysis® (PFA) alerts v Redundant Ethernet capabilities with failover support v Redundant power supplies and redundant hot-swap fans (ac power supplies are hot-swap) v Remind button to temporarily turn off the system-error LED v Remote system problem-determination support v Standby voltage for systems-management features and monitoring Chapter 1.

v
Systems-management
capabilities
The
server
supports
an
optional
IBM
Remote
Supervisor
Adapter
II
SlimLine.
When
you
use
this
adapter,
you
can
manage
the
functions
of
the
server
locally
and
remotely.
The
Remote
Supervisor
Adapter
II
SlimLine
also
provides
system
monitoring,
event
recording,
and
dial-out
alert
capability.
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
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.
