What your server offers
Your server uses the following features and technologies:
v IBM Director
IBM Director is a workgroup-hardware-management tool that you can use to
centrally manage xSeries servers. For more information about IBM Director, see
the IBM Director User’s Guide on the IBM Director CD.
v IBM Enterprise X-Architecture technology
IBM X-Architecture technology combines proven, innovative IBM designs to make
your Intel-processor-based server powerful, scalable, and reliable. For more
information, go to
http://www.ibm.com/pc/us/eserver/xseries/xarchitecture/enterprise/index.html.
– Active
™
Memory
The Active Memory feature improves the reliability of memory through memory
mirroring, memory scrubbing, and the Memory ProteXion
™
feature. For more
information, see “Active Memory” on page 7.
– Large system-memory capacity
The memory bus supports up to 64 GB of system memory. The memory
controller supports error correcting code (ECC) for up to 32 industry-standard
PC1600, 133 megahertz (MHz), 3.3 V, 168-pin, registered, double-data-rate
(DDR), synchronous dynamic random access memory (SDRAM) dual inline
memory modules (DIMMs).
– Memory ProteXion
The Memory ProteXion feature provides the equivalent of a hot-spare drive in
a RAID array. It is based in the memory controller, and it enables the server to
sense when a chip on a DIMM has failed and to route the data around the
failed chip.
– XceL4
™
Server Accelerator Cache
The XceL4 Server Accelerator Cache provides 64 MB of external Level-4
cache per SMP Expansion Module, which increases memory bandwidth and
reduces access time through PCI-X, Ethernet, SCSI, and Fibre Channel
interfaces.
v
IBM ServerGuide
™
Setup and Installation CD
The ServerGuide Setup and Installation CD that comes with your server provides
programs to help you set up your server and install the operating 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 ServerGuide Setup and
Installation CD” on page 27.
Note: If your server model came with an operating system, such as Microsoft
®
Windows
®
2000 Datacenter Server, Windows Server 2003 Datacenter Edition, or
VMware ESX server, see the software documentation provided with your
software for configuration information.
v Integrated network support
Your server comes with an integrated Broadcom 5704 Dual 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 30.
4 xSeries 445 Type 8870: User’s Guide

v Large data-storage capacity and hot-swap capability
Your server supports up to two 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.
v Light path diagnostics feature
The light path diagnostics feature provides LEDs to help you diagnose problems.
For more information, see the section about the light path diagnostics feature in
the Installation Guide.
v Redundant connection
The integrated dual Gigabit Ethernet ports provide a failover capability. If a
problem occurs with the primary Ethernet connection, all Ethernet traffic
associated with the primary connection is automatically switched to the
secondary connection. If the appropriate device drivers are installed, this
switching occurs without data loss and without user intervention.
v Redundant cooling and power capabilities
The redundant cooling of the fans in your server enable continued operation if
one of the fans fails. Your server comes with two 1050-watt or two 1200-watt
hot-swap power supplies, which provide redundant power for many server
configurations. If the maximum load on your server is less than 1050 watts (or
1200 watts depending on your model) and a problem occurs with one of the
power supplies, the other power supply can meet the power requirements.
v Scalable partitions
Your server is scalable and can be connected to another server so that you can
share resources between servers.
v ServeRAID
™
support
Your server supports ServeRAID adapters to create redundant array of
independent disks (RAID) configurations.
v Symmetric multiprocessing (SMP)
Your server supports up to eight Intel Xeon microprocessors (sixteen in a 16-way
configuration). The server comes with two microprocessors. You can install
additional microprocessors to enhance performance.
v Systems-management capabilities
The server comes with a Remote Supervisor Adapter or a Remote Supervisor
Adapter II-EXA installed. The adapter and the systems-management software
that comes with your server enable you to manage the functions of the server
locally and remotely. Both adapters provide system monitoring, event recording,
and dial-out alert capability. The Remote Supervisor Adapter II-EXA also provides
an integrated video controller.

6 xSeries 445 Type 8870: User’s Guide

Active Memory
Active Memory is an IBM feature that improves the reliability of memory through
memory mirroring, memory scrubbing, and the Memory ProteXion feature.
Memory scrubbing and Memory ProteXion
Memory scrubbing tests the memory at regular intervals to detect and report
potential memory errors before they can cause server outages.
If a detected error is recoverable, the Memory ProteXion feature corrects the error
and rewrites the data to another memory location on the same DIMM. The error is
logged in the error log so that you can determine whether preventive maintenance
is necessary.
If there are not sufficient undamaged memory locations that the data can be
rewritten to, the error is unrecoverable. Other conditions can also cause
unrecoverable errors. If a detected error is unrecoverable, LEDs on the Light Path
Diagnostics panel are lit to indicate the failing DIMM.
You do not have to enable memory mirroring to use memory scrubbing and the
Memory ProteXion feature.
Memory mirroring
Memory mirroring stores data in memory port 1 and memory port 2 simultaneously.
To support memory mirroring, you must install identical dual inline memory modules
(DIMMs) in memory port 1 and memory port 2. For more information, see the
section about installing memory modules in the Option Installation Guide on the IBM
xSeries Documentation CD.
To enable memory mirroring through the Configuration/Setup Utility program, select
Advanced Setup from the main menu, and then select Memory Settings. For
more information about using the Configuration/Setup Utility program, see

When memory mirroring is enabled, BIOS will only report half of the installed
memory. For example, if you have 64 GB of memory installed and memory
mirroring is enabled, BIOS will only report 32 GB of memory.
Note: To use the hot-add memory feature, memory mirroring must be disabled in
the BIOS code.
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 your
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
