What the server offers

The server uses the following features and technologies:

Active PCI (hot-plug) adapter capabilities

The server has one hot-plug slot for a peripheral component interconnect (PCI)
adapter. With operating system support, you can replace a failing hot-plug a PCI
adapter without turning off the server. If the operating system and the adapter
support the hot-add feature, you can also add a PCI adapter in this slot without
turning off the server.

Active PCI Express X4 adapter capabilities

The server has two slots for PCI Express X4 adapters.These slots will accept X8
adapters, however they will operate as a X4 adapter.

Baseboard management controller

The baseboard management controller provides environmental monitoring for the
server. If an environmental condition exceeds a threshold or if a system
component fails, the baseboard management controller lights LEDs to help you
diagnose the problem. Critical errors are also included in the error log.

Note: The baseboard management controller is also known as the service

processor.

IBM Director

IBM Director is a workgroup-hardware-management tool that you can use to
centrally manage xSeries servers. For more information, see the IBM Director
documentation on the IBM Director CD.

Memory mirroring

Memory mirroring improves the reliability of memory by writing information to the
main memory and redundant locations in a mirrored pair of DIMMs. For more
information, see “Memory mirroring” on page 7.

Online-spare memory

Online-spare memory disables failed memory from the system configuration and
activates an online-spare memory pair of DIMMs to replace the failed pair. For
more information, see “Online-spare memory” on page 7.

Large system-memory capacity

The server supports up to 16 GB of system memory. The memory controller
supports error correcting code (ECC) for up to eight single-sided
industry-standard PC3200, 400 megahertz (MHz), 1.8 V, 240-pin, registered,
double-data-rate (DDR) II, synchronous dynamic random access memory
(SDRAM) dual inline memory modules (DIMMs). The memory controller also
provides Chipkill

™

Memory protection if the DIMMs are all type x4 and larger
than 128 MB. Chipkill Memory protection is a technology that protects the server
from a single chip failure on a DIMM.

IBM ServerGuide

system. The ServerGuide program detects installed hardware options and
provides the correct configuration programs and device drivers. For more
information about the ServerGuide Setup and Installation CD, see “Using the

Integrated network support

The server comes with dual integrated Broadcom Gigabit Ethernet controllers,
which support connection to a 10-Mbps, 100-Mbps, or 1000-Mbps network. For
more information, see “Configuring the Ethernet controllers” on page 26.

Large data-storage capacity and hot-swap capability

The server supports up to six 25.4-mm (1-inch) slim-high, 3.5-inch 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.

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 Hardware

Maintenance Manual on the IBM xSeries Documentation CD.

Redundant connection

The addition of an optional network interface card (NIC) provides a 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.

Redundant power and cooling capabilities

The server supports up to two 670-watt hot-swap power supplies. If the server
comes with only one power supply, you can install an additional power supply
with two redundant cooling fans to add redundant power and cooling capabilities.

the maximum load on the server is less than 670 watts and a problem occurs
with one of the power supplies, the other power supply can meet the power
requirements. The redundant cooling of the fans enables continued operation if
one of the fans fails.

ServeRAID

™

support

The server supports ServeRAID adapters to create redundant array of
independent disks (RAID) configurations.

Symmetric multiprocessing (SMP)

The server supports up to two Intel Xeon microprocessors. If the server comes
with only one microprocessor, you can install an additional microprocessor to
enhance performance and provide SMP capability.

Systems-management capabilities

The server supports an optional Remote Supervisor Adapter II Slimline. When
this adapter is used with the integrated baseboard management controller that
comes with the server, 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.

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

stored in the server, the availability of the server when you need it, and the ease

with which you can diagnose and correct problems.

Memory mirroring

Memory mirroring stores data in two pairs of DIMMs simultaneously. To support
memory mirroring, you must install identical dual inline memory modules (DIMMs) in
all DIMM slots. For more information, see the section about installing memory
modules in the Option Installation Guide on the IBM xSeries Documentation CD.

enable memory mirroring through the Configuration/Setup Utility program, select

Advanced Setup from the main menu, and select Memory Configuration. For
more information about using the Configuration/Setup Utility program, see
Chapter 2, “Configuring the server,” on page 17.

Online-spare memory disables a failed DIMM pair from the system configuration
and activates an online-spare memory DIMM pair to replace the failed pair. Before
you can enable this feature, you must install one additional pair of DIMMs. The
online-spare memory DIMM pair must be the same speed and type, and the same
size as the active DIMM pair or larger.

Enable online-spare memory through the Configuration/Setup Utility program. The
BIOS assigns the online-spare memory DIMM pair according to your DIMM
configuration. See “Using the Configuration/Setup Utility program” on page 17 for
further details about enabling online-spare memory. See Table 3 for the online-spare
memory DIMM connector assignments.

The UpdateXpress program

The UpdateXpress program is available for most xSeries servers and server
options. It detects supported and installed device drivers and firmware in the server
and installs available updates. You can download the UpdateXpress program from
the Web at no additional cost, or you can purchase it on a CD. To download the
program or purchase the CD, go to
