GB of ECC fully buffered DIMM (FBDIMM) DDR2-800/667 SDRAM. Memory can be installed
in both interleaved (dual-channel) and non-interleaved (single-channel) configurations. All
memory modules used to populate the system should be the same size, type, and speed.
Figure 1-3). Below are the main features of the node board.
The node board memory controller supports memory mirroring to prevent data loss in case of
DIMM failure. The system maintains two copies of all the data in memory; therefore, a mirrored
system uses only half of the installed DIMMs. If a DIMM fails, the system recovers the second
copy of data from the mirrored DIMM in the opposite channel. If both the primary and the
mirrored copy of the data become corrupt, the system will fail. Configure memory mirroring with
the Memory Branch Mode BIOS setting (refer to
“Memory Branch Mode” on page 114.
Serial ATA (SATA)
The southbridge (ESB2 chip) of the 5400P chipset includes a SATA controller for 3-Gb/s SATA
drives. The hot-swappable SATA drives are connected to a backplane (refer to
provides power, bus termination, and configuration settings.

1: Introduction
Serial Attached SCSI (SAS) and RAID Support
Appendix F, “Upgrading for SAS/SATA RAID Support,” describes how to upgrade your server
to use SAS hard drives as well as SATA hard drives by using model LSISAS3444E HBAs. This
HBA option also can provide support for RAID 0, RAID 1, or JBOD.
PCIe Expansion Slots
Each node board supports one PCI-Express 2.0 x16 slot. Two PCIe slots are available in the server
chassis.
Ethernet Ports
T wo Intel 82563EB network controllers are integrated into the 5400P chipset on each of the node
boards to support a total of four Gigabit LAN ports (100/1000
output).
Base-T/1000 BaseTX, RJ45
Onboard Controllers/Ports
Each node board I/O panel ports includes one COM port, a VGA port, two USB ports, two Gigabit
Ethernet LAN (NIC) ports, and one optional InfiniBand
®
port.
ATI Graphics Controller
The SGI Altix XE320 features an integrated ATI video controller based on the ES1000 graphics
chip. The ES1000 was designed specifically for servers, featuring low-power consumption, high
reliability, and superior longevity.
Other Features
Other onboard features that enable reliable service include voltage monitors, a chassis intrusion
header, auto-switching voltage regulators, chassis and CPU overheat sensors, virus protection,
and BIOS rescue.

Server Chassis Features
This section describes the main features of the SGI Altix XE320 1U chassis. Refer to Chapter 5,
“Advanced Chassis Setup.” for more detailed information.
Note: For more detail on the chassis, refer to Chapter 5, “Advanced Chassis Setup.”
System Power
A single power supply (refer to Figure 1-2) provides the power for both node boards. Each node
board however, can be shut down independently of the other with the power button on its own
control panel.
Although they share a common power supply, the I2C signals used for power supply monitoring
are received by the node board 1 only. (When viewed from the front of the chassis, the node board
on the left is node board 1 and the node board on the right is the node board 2.)
Server Chassis Features
SATA/SAS Backplane/Drives
As a system, the SGI Altix XE320 supports four SA TA/SAS disk drives (refer to Figure 1-2). The
SA TA/SAS backplane is divided into two sections. A single power connector is used for the entire
backplane, but other functions, such as circuit board over-temperature monitoring, apply to both
sections. Each pair of disk drives is logically connected to its own node board. Consequently, the
RAID configuration is limited to a two-drive scheme (RAID 1 or RAID 0). The RAID
configuration cannot be set up across all four drives.
Control Panel
The chassis features two independent control panels associated with each node board in the
chassis. Each control panel has LEDs to indicate power on, network activity, hard disk drive
activity, and system overheat conditions. Each control panel also includes a main power button
and a system reset button.
007-5466-001 7
Rear I/O Panel
The I/O panel provides slots for two low-profile PCI-Express 2.0 x16 expansion cards, two COM
ports, four USB ports, two VGA ports, and four Gb Ethernet ports. The server also provides two
InfiniBand ports.
Cooling System
The server chassis has an innovative cooling design that features two sets of triple (for a total of
six) 4-cm high-performance fans. A fan speed control setting in BIOS allows fan speed to be
determined by system temperature.
System Security and Pre-Installed Linux Operating Systems
If your server was shipped with a pre-installed Linux® operating system, the password for root
was set to sgisgi for your convenience. You should change this password at your earliest
opportunity. Consult your Linux documentation for the procedure.

2. Server Installation
This chapter provides a quick setup checklist to get the SGI Altix XE320 operational.
Unpack the System
Inspect the shipping container that the SGI Altix XE320 was shipped in and note if it was damaged
in any way. If the server shows damage, file a damage claim with the carrier who delivered it.
Decide on a suitable location for the rack that supports the weight, power requirements, and
environmental requirements of the SGI Altix XE320 server. It should be situated in a clean,
dust-free environment that is well ventilated. Avoid areas where heat, electrical noise, and
electromagnetic fields are generated. Place the server rack near a grounded power outlet. Refer to
“Warnings and Precautions” on page 10.
Prepare for Setup
The shipping container should include two sets of rail assemblies, two rail mounting brackets and
the mounting screws that you will use to install the system into a rack.
Read this section in its entirety before you begin the installation procedure.
Choose a Setup Location
• Leave enough clearance in front of the rack to enable you to open the front door completely,
approximately 25 in. (65 cm).
• Leave approximately 30 in. (76 cm) of clearance in the back of the rack to allow for
sufficient airflow and ease in servicing.

simultaneously may cause the rack to tip over and result in serious injury or death.
10 007-5466-001
Server Precautions
• Review the electrical and general safety precautions in Appendix E, “System Safety.”
• Determine the placement of each component in the rack before you install the rails.
• Install the heaviest server components in the bottom of the rack first, and then work up.
• Use a regulating uninterruptible power supply (UPS) to protect the server from power surges
and voltage spikes and to keep your system operating in case of a power failure.
• Allow the hot plug SATA drives and power supply modules to cool before touching them.
• Always keep the rack’s front door and all panels and components on the servers closed when
not servicing to maintain proper cooling.
Rack Mounting Considerations

Circuit Overloading
Consideration should be given to the connection of the equipment to the power supply circuitry
and the effect that any possible overloading of circuits might have on overcurrent protection and
power supply wiring. Appropriate consideration of equipment nameplat e ratings should be used
when addressing this concern.
Reliable Ground
A reliable ground must be maintained at all times. To ensure this, the rack itself should be
grounded. Particular attention should be given to power supply connections other than the direct
connections to the branch circuit (i.e. the use of power strips, etc.).
Install the System into a Rack
This section provides information on installing the SGI Altix XE320 into a rack unit with the rack
rails provided. If the system has already been mounted into a rack, refer to
Setup” on page 21. There are a variety of rack units on the market, which may mean the assembly
procedure will differ slightly . You should also refer to the installation instructions that came with
the rack unit you are using.
“Check the Node Board
Identify the Sections of the Rack Rails
You should have received two rack rail assemblies in the rack mounting kit. Each assembly
consists of two sections: an inner fixed chassis rail that secures directly to the server chassis and

Locking Tabs
Both chassis rails have a locking tab (refer to Figure 2-1), which serves two functions: the first is
to lock the server into place when it is installed in the rack; the second is to lock the server in place
when it is fully extended from the rack. The locking tab prevents the server from being removed
from the rack accidentally when you pull it out for service.
Install the Server in a Rack
Warning: The SGI Altix XE320 server weighs 40 lb (18 kg). Always use proper lifting
techniques when your move the server . Always get the assistance of another qualified person

Check the Node Board Setup
Depending upon your system configuration, your system may have one or more drives installed.
For detailed information about how to install SATA/SAS drives, refer to
Chassis Setup.”
Check the Airflow
Airflow is provided by six sets of 4-cm fans (each set of fans consists of two fans that are mounted
back to back). The system component layout was carefully designed to direct sufficient airflow to
cool the components that generate the most heat. Note that all power and data cables have been
routed in such a way that they do not block the airflow generated by the fans. An air shroud is also
installed to focus the airflow to areas where the most heat is generated.
Supply Power to the System
If necessary , install the system in a rack (refer to “Install the System into a Rack” on page 12), and
connect the power cord from the power supply module into a power strip or power distribution
unit (PDU). The PDU offers protection from electrical noise and power surges. SGI also
recommends that you use an uninterruptible power supply (UPS) source.

5. Apply a small amount of thermal interface material (TIM) on the surface of the CPU before
you install the heatsink.
Replace the Thermal Interface Material
The Intel Xeon processors used in your server require a thermal interface material (TIM) between
the processors and heatsinks to properly dissipate the heat that is generated by the processors. If
you replace a processor and/or heatsink, you will need to remove the existing TIM from the
processor and heatsink. Then, you will need to apply new TIM to the processor before you install
the heatsink.
The TIM application instructions accompany the new TIM. The following subsections describe
how to remove the existing TIM:
• “Removing TIM from a Processor” on page 42
• “Removing TIM from a Heatsink” on page 46
Removing TIM from a Processor
You should always remove theTIM from a processor before you remove it from the node board.
Warning: Always wear gloves when performing this procedure to avoid direct skin
contact with the TIM, which is a potentially toxic material.
Tools/Parts Required:
• Dry, lint-free cloth
• Lint-free cloth moistened with isopropyl alcohol
• Gloves
Caution: T o prevent the processor from moving in its socket, ensure that the processor load lever
remains engaged while you perform the following procedure. If the processor moves while you
remove the TIM, the pins on the processor might be damaged.

!
Caution: Exercise extreme care when installing or removing DIMM modules to prevent damage
to the node board or DIMM module.
The node board provides eight 240-pin DIMM sockets that can support up to 64 GB of error
correction code (ECC) fully buffered DIMM (FBDIMM) DDR2-800/667 SDRAM (for a total of
128 GB in the system). The memory scheme is interleaved; therefore, you must always add
memory to two memory DIMM slots at a time.
installation. Figure 4-11 shows the DIMM slot designations and bank locations on the node board.
The memory controller hub (MCH) supports FBDIMM in dual-channel mode. There are a
maximum of eight DIMMs in each node board and DIMMs must be populated in groups of two
(a DIMM pair).
There are four DIMM pairs as follows:
• DIMM pair 1: 1A and 2A
• DIMM pair 2: 3A and 4A
• DIMM pair 3: 1B and 2B
• DIMM pair 4: 3B and 4B
Table 4-2 lists how to optimize your DIMM
A minimum of one DIMM pair must be installed. Figure 4-6 illustrates the minimum population
for such a configuration.

to size, speed, and organization. The MCH will adjust to the lowest-speed DIMM.
007-5466-001 51
4: Advanced Node Board Setup
Performance Optimization
The primary rule for installing DIMMs to obtain maximum performance is the following:
Balance the DIMM memory capacity across both memory branches.
As illustrated in Figure 4-6, the MCH has memory Branch 0 and Branch 1. DIMMs 1A, 1B, 2A,
and 2B are on Branch 0 and DIMMs 3A, 3B, 4A, and 4B are on Branch 1. If the total memory
capacity of the DIMMs on each branch is not balanced, the memory performance will be
degraded.
Table 4-1 lists the recommended DIMM configurations to achieve maxim um performance.

Memory Mirroring Mode
The memory controller supports memory mirroring to prevent data loss in case of DIMM failure.
The system maintains two copies of all the data in memory; therefore, a mirrored system uses only
half of the installed DIMMs. If a DIMM fails, the system recovers the second copy of data from
the mirrored DIMM in the opposite channel. If both the primary and the mirrored copy of the data
becomes corrupt, the system will fail.
To select memory mirroring mode, you must select mirroring in the BIOS setup:

Figure 4-7 illustrates the standard DIMM population for mirroring mode.
The minimum number of DIMM supported in mirror mode is four. All four DIMMs must be
identical in size, speed, and organization.
Mirroring Mode Upgrade
To upgrade DIMM memory in mirroring mode, you must add four additional DIMMs. The
additional four must be identical to initial four, except for speed. The MCH will adjust to the
lowest-speed DIMM.
Install DIMMs
Align the DIMM so that the notch along the bottom of the DIMM module (refer to Figure 4-8 and
Figure 4-9) aligns with the notch in the DIMM slot. Insert DIMMs vertically and gently press
down on the DIMM until it snaps into place.
Note: Refer to “Install or Remove the Air Shroud” on page 57 for a procedure on how to remove
and install the air shrouds.
An “X” in the slot number (refer to Table 4-2) indicates that a DIMM slot is populated; “----”
indicates a DIMM slot is not populated. Both fully buffered 667 MHz and 800 MHz DIMMs are
supported, however, you need to use memory modules of the same speed and of the same type.
Interleaved memory is supported only when pairs of DIMMs are installed in both Bank 1 and
