Chapter 1. Introducing the IBM xSeries 235 Type 8671 server 3

What your server offers
The design of your server takes advantage of advancements in symmetric
multiprocessing (SMP), data storage, disk-array technologies, and memory
management. Your server combines:
vIBM X-Architecture technology
IBM X-Architecture features leverage proven innovative IBM technologies to build
the most powerful, scalable, reliable Intel-processor-based servers in the world.
X-Architecture features include Light Path Diagnostics, Chipkill
™ memory,
Predictive Failure Analysis (PFA), and the Advanced System Management
processor.
vImpressive performance using SMP
Your server supports up to two Intel Xeon microprocessors. Your server comes
with at least one microprocessor installed; if it comes with one microprocessor,
you can install an additional microprocessor to enhance performance and provide
SMP capability.
vLarge data-storage and hot-swap capabilities
All models of the server support up to six 25.4 mm (1-inch) slim-high, 3.5-inch
hot-swap hard disk drives in the hot-swap bays. This hot-swap feature enables
you to add, remove, or replace hard disk drives without turning off the server.
vActive PCI (hot-plug) adapter capabilities
Your server has two hot-plug slots for peripheral component interconnect (PCI)
adapters. With operating system support, you can replace failing hot-plug PCI
adapters without turning off the server. You can also add PCI adapters in these
slots without turning off the server, if the operating system and the adapter
support the hot-add feature.
vRedundant cooling and power capabilities
The redundant cooling and hot-swap capabilities of the fans in your server
enable continued operation if one of the fans fails. You can also replace afailing
fan without turning off the server.
Some models of the server come with two hot-swap 560-watt power supplies.
The two hot-swap power supplies provide redundant power for many server
configurations. If aproblem occurs with one of the power supplies, the other
power supply can handle the load. The NONREDUNDANT light-emitting diode
(LED) on the diagnostic LED panel is lit when aproblem is detected with one of
the redundant hot-swap power supplies. For models that come with one fixed
560-watt power supply, ahot-swap power-supply option containing two hot-swap
560-watt power supplies is available; you can replace the fixed power supply with
the hot-swap power-supply option to provide redundancy. (See the Option
Installation Guide on the IBM xSeries Documentation CD for instructions.)
vLarge system memory
Your server supports up to 6GB of system memory. The memory controller
provides error correcting code (ECC) support for up to six industry-standard, 133
MHz/266 MHz, 2.5 V, 184-pin, double-data-rate (DDR), PC2100 registered,
synchronous dynamic random-access memory (SDRAM) dual inline memory
modules (DIMMs). The memory controller also provides Chipkill Memory
protection if all DIMMs are of the type x4. Chipkill Memory protection is a
technology that protects the server from asingle chip failure on aDIMM.
vSystem-management capabilities
Your server comes with an integrated system management processor (ISMP) and
support for the Remote Supervisor Adapter. The ISMP, in conjunction with the
4IBM xSeries 235 Type 8671: User’s Guide

system-management software that is provided with your server, enables you to
manage the functions of the server locally and remotely. The ISMP also provides
system monitoring and event recording.
Note: The ISMP is sometimes referred to as the service processor.
The optional IBM Remote Supervisor Adapter works with the integrated service
processor to give you aWorld Wide Web interface to the system-management
functions. You can manage your server over the Internet or intranet.
See the documentation provided with your system-management software for
more information. To order an optional Remote Supervisor Adapter, contact your
IBM marketing representative or authorized reseller.
vIntegrated network environment support
Your server comes with an integrated Broadcom Gigabit Ethernet controller on
the system board. This Ethernet controller has an interface for connecting to
10/100/1000-Mbps networks. The server automatically selects between
10BASE-T and 100/1000BASE-TX environments. The controller provides
full-duplex (FDX) capability, which enables simultaneous transmission and
reception of data on the Ethernet local area network (LAN). This controller
supports Wake on LAN
® technology.
vRedundant connection
The addition of an optional network-interface card (NIC) provides afailover
capability to aredundant Ethernet connection. If aproblem occurs with the
primary Ethernet connection, all Ethernet traffic associated with this primary
connection is automatically switched to the redundant NIC. If the appropriate
device drivers are installed, this switching occurs without data loss and without
user intervention.
vIBM 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 22.
vIBM Director
IBM Director is aworkgroup-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 xSeries Documentation CD.
Reliability, availability, and serviceability
Three of the most important features in server design are reliability, availability, and
serviceability (RAS). These factors help to ensure the integrity of the data stored on
your server; that your server is available when you want to use it; and that should a
failure occur, you can easily diagnose and repair the failure with minimal
inconvenience.
The following is an abbreviated list of the RAS features that your server supports:
vActive PCI
™ (hot-plug) adapter slots
vAutomatic error retry and recovery
vAutomatic restart after apower failure
vBackup basic input/output system (BIOS) switching under the control of the
