About This Guide
This guide provides an overview of the Silicon Graphics Prism Visualization System
components and describes how to set up and operate this system.
The most basic Silicon Graphics Prism consists of a base compute module combined with
an extensible graphics 2-processor capable node module (XG2N module). Larger
systems use a base compute module, XG2N module(s), and other optional modules that
are rackmounted together. The following optional modules are available:
• A CPU expansion module provides zero, one or two additional 64-bit Intel
processors and up to 24 GB of memory. No PCI or disk options are available in this
module.
• A CPU, memory and PCI/PCI-X expansion (CMPX) module provides zero, one or
two optional processors, up to 24 GB of memory, and four PCI and PCI-X card slots.
• A Router module provides eight NUMAlink-4 ports and functions as a high-speed
switch to route network packets between base compute, XG2N, CPU expansion,
and CMPX modules.
• The SGI TP900 storage module provides additional disk storage to the system. For
detailed information about this module, see SGI Total Performance 900 Storage System
User’s Guide (007-4428-00x). Note than an optional SCSI PCI card is required to use
this option in a Silicon Graphics Prism.
This guide is written for owners, system administrators, and users of the Silicon Graphics
Prism. It is written with the assumption that the reader has a good general knowledge of
computer graphics and computer operations.

1. Getting Started with the Silicon Graphics Prism
The Silicon Graphics Prism Visualization System platform is a high-performance
highly-scalable system running the SGI Linux + ProPack operating system. The platform
is available in a number of configurations to meet your visualization and compute
requirements.
This chapter introduces the two primary modules used in the system, and provides an
abbreviated overview (quick start) on how to begin using your system. The following
chapters elaborate on various topics relating to larger systems, configuration and cabling
questions, component replacement and upgrades, basic troubleshooting, rack mounting,
and connector functionality.

XG2N and Compute Modules
The most basic Silicon Graphics Prism uses two modules:
• A graphics 2-processor and memory capable node module (called an XG2N
module).
• A base compute module that provides base I/O as well as processors and memory.
The XG2N module is a 2U rack mountable enclosure which, in addition to the two
high-performance graphics pipes, adds to the host system a node board with two CPUs
and four, eight, or twelve memory DIMMs. This module connects as an integral part of
the system’s compute/memory fabric. Though it contains CPUs and memory, the XG2N
module does not have boot I/O functionality, and therefore may not be used as a
standalone system.
The rear panel of the XG2N module
page 3. The rear panel of the XG2N modul e
with FireGL X2PRO-256 is shown in Figure 1 -1 on
with FireGL X3-256 is shown in Figure 1-3 on
page 4.
The XG2N module is a node-connected module, and therefore connects to the host
system using NUMAlink, either directly or through an optional NUMAlink module
(router). This way the XG2N module becomes an integral part of the system, and can
contain both CPUs and memory, in addition to graphics output capabilities. Note that
NUMAlink routers may be available only with specific system configurations. Check
with your SGI sales or service representative for information on available configurations.
Each XG2N module contains two graphics pipes, each capable of supporting two display
devices. In systems with only two pipes, the pipe and channel designations are defined
as in Figure 1-1 and Figure 1-3. In systems with more than one XG2N graphics module
the pipes are numbered as shown in Figure 1-2 and Figure 1-4.

• Power button. Press this button to power on the individual module. Alternatively,
you can power on all the system modules at once from an optional system console.
• Reset button. Press this button to reset the internal processors and ASICs. The reset
will cause a memory loss.
• NMI button. Pressing this button issues a non-maskable interrupt command to a
module. When the system hangs, you can send the affected module an NMI
interrupt. The interrupt goes to PROM and causes the CPU state to be captured for
that module. This information is saved in flash PROM and in the system log, and
can assist SGI technicians in debugging system hangs and customer problems.

2: System Overview and Options
Physical Features
The Silicon Graphics Prism platform is the latest advancement in the SGI NUMAflex
approach to Linux based modular visualization and computing. It is designed to deli ver
maximum sustained performance in a compact system footprint. Independent scaling of
graphics pipes, computational power, I/O bandwidth, and in-rack storage lets you
configure a system to meet your unique visualization and computational needs.
The system can be expanded from a two-module system with two graphics pipes, up to
48 GB of memory, and 4 PCI/PCI-X slots to a higher-performance system that contains
16 processors, 192 GB local DIMM memory, and 28 PCI/PCI-X slots. Note that many of
the available PCI/PCI-X slots may be used to support I/O, USB, ImageSync, or optional
audio or SCSI cards needed for the system.
For most configurations, the visualization system is housed in one 17U rack or one 39U
rack as shown in Figure 2-1; however, for small system configurations, the system
modules can be placed on a table top.
Systems that are housed in 17U racks have a maximum weight of approximately 610 lb
(277 kg). The maximum weight of systems that are housed in 39U racks is approximately
1,366 lb (620 kg). The racks have casters that enable you to remove the system from the
shipping container and roll it to its placement at your site.
Check with your SGI service representative for additional physical planning information
or documentation that may be available.
For more information about the technical specifications of your system and individual
modules, see Appendix A, “Technical Specifications,” in this manual.

Functional Architecture
The Silicon Graphics Prism is based on the SGI NUMAflex architecture, which is a
shared-memory system architecture that is the basis of SGI HPC servers and
supercomputers. The NUMAflex architecture is specifically engineered to provide
technical professionals with superior performance and scalability in a design that is easy
to deploy, program, and manage. It has the following features:
Shared access of processors, memory, and I/O. The Super Hub (SHub) ASICs and the
NUMAlink interconnect functions of the NUMAflex architecture enable applications to
share processors, memory, and I/O devices.
• Each Super-Hub (SHUB) ASIC in the system acts as a memory controller between
processors and memory for both local and remote memory references.
• The NUMAlink interconnect channels information between all the modules in the
system to create a single contiguous memory in the system of up to 192 GB and
enables every processor in a system direct access to every I/O slot in the system.
Together, the SHub ASICs and the NUMAlink interconnect enable efficient access to
processors, local and remote memory, and I/O devices without the bottlenecks
associated with switches, backplanes, and other commodity interconnect technologies.
System scalability. The NUMAflex architecture incorporates a low-latency,
high-bandwidth interconnect that is designed to maintain performance as you scale
system computing, I/O, and storage functions. For example, the computing dimension
in some system configurations can range from 4 to 16 processors in a single system image
(SSI).
Efficient resource management. The NUMAflex arc hitecture is designed to run complex
models and, because the entire memory space is shared, large models can fit into
memory with no programming restrictions. Rather than waiting for all of the processors
to complete their assigned tasks, the system dynamically reallocates memory, resulting
in faster time to solution.

Functional Architecture
A Silicon Graphics Prism system contains a combination of the following modules:
• Base compute module. All Silicon Graphics Prism systems include at least one base
compute module that contains the following components:
– A node board with two Intel Itanium 2 processors (each processor has
integrated L1, L2, and L3 caches), between 2 GB and 24 GB of local memory,
and a SHUB ASIC (the crossbar between the processors, local memory, the
network interface, and the I/O interface).
– Four PCI/PCI-X slots
– One four-port USB card that comes factory-installed in the top PCI/PCI-X slot
– One IO10 PCI card that comes factory-installed in the lowermost PCI/PCI-X
slot
Note: See “Optional IO9 PCI Card” on page 53 for information about the
optional IO9 card.
Note: Each system or partition requires a minimum of base I/O card. The
standard card providing this base I/O functionality is an IO10 PCI card.
Additional IO10 cards are required if you want additional serial ATA hard drives
and/or DVD-ROM drives in additional modules. These cards must reside in
additional base compute modules (no more than one card per module).
The IO10 card has real-time interrupt input and output ports, an Ethernet port,
and a multi-port serial adapter connector. The IO10 card is also needed to
support a base module’s serial ATA disk drive(s), and DVD-ROM.
Note: The RT interrupt input and RT interrupt output functionality of the IO10
PCI card is not supported under SGI Linux + ProPack.
– A bootable hard drive
– A DVD-ROM drive

Router Module
The optional router module (sometimes called an R-brick) is an eight-port 2U-high
module that functions as a high-speed switch to route network packets between base
compute, XG2N, CPU expansion, and CMPX modules. This creates a NUMAlink-4
interconnect fabric (as opposed to the ring topology normally used in smaller system
configurations). The optional router is generally only used when ther e are four and eight
modules interconnected as a single system image.
The section “NUMAlink Cabling in Routed Systems” on page 65 details the cable
connection points used in a system with a router.
The key component within the module is the router chip, an SGI custom-designed ASIC.
The router chip is an eight-port crossbar that connects any input-link channel to any of
the seven possible output-link channels (ports).
The router has the following features:
• Eight NUMAlink-4 channels
• One USB port for system controller support
• One L1 controller and LCD display
• One 9-pin console connector
• Two hot-pluggable cooling fans (not customer replaceable)

Power Co mponents
The Silicon Graphics Prism platform can contain the following power components:
• One or two power distribution units (PDUs). The second PDU is added to the
system only when more than 10 AC power receptacles are needed within the rack.
The PDU inputs AC voltage from an external power receptacle and it can output
AC voltage to the base compute modules, XG2N graphics modules, CPU expansion
modules, CMPX modules, router modules, and TP900 storage modules.
See Figure 1-9 on page 14 for an example.

SGI Racks for Silicon Graphics Prism
The system is offered in two rack types: a short rack and a tall rack. The racks are
measured in standard rack units (U); one U is equal to 1.75 in. (4.45 cm). The short rack
is a 17U rack (see Figure 2 -11). The tall rack is a 39U rack (see Figure 2-14).
Each component within the rack is identified by the lowest U number that it occupies.
For example, the top (XG2N) module shown in Figure 2-11 is described as being located
in U12.

Optional IO9 PCI Card
Optional Devices
If you do not wish to use the IO10 base I/O card in your system, an optional IO9 PCI card
is required for base I/O functionality. Each system must contain at least one base I/O PCI
card for base I/O functionality within th e system. This PCI card must r eside in bus 1, slot
1 (the bottom slot) of the lowest base compute module in the system. The IO9 PCI card
has the following connectors:
• External VHDCI 68-pin SCSI co nn ector
• 10/100/1000BaseT Ethernet connector
• Real-time interrupt output (RTO) and real-time interrupt input (RTI) connectors
Note: The RT interrupt input and RT interrupt output functionality of the IO9 PCI
card is not supported under SGI Linux + ProPack.
The optional IO9 card also contains an IOC-4 ASIC that supports the following features:
• One IDE channel for the DVD-ROM
Optional Tape Devices
• NVRAM and time-of-day clock
The Silicon Graphics Prism supports optional or third-party tape drives. For current tape
solutions for your system visit:

Your DM8 audio board is tested for operation in specific SGI visualization systems.
Select SGI Linux based systems support use of a single DM8 audio board (check with
your SGI sales or support representative for functional confirmation). It is recommended
that it not be removed and installed in other SGI systems.
SGI Linux based visualization systems support only one DM8 option board. Under most
circumstances you should always leave the DM8 installed in the original
factory-configured slot. If it does become necessary to either move or replace the board,
use the information on removing and r eplacing PCI cards in your system user’s guide for
step-by-step instructions. If you don’t have the printed user guide handy, it is available
on the Internet in the SGI Technical Publications Library at the following location:

Optional USB Extender
You can plug the keyboard and mouse directly into the USB connectors of a compute
module (see “Connecting a Keyboard and Mouse” on page 19), or you can use an
optional USB extender that allows you to place the keyboard and mouse up to 328.68 feet
(100 m) from the compute module, see Figure 2-16 on page 58.
Note: The local extender (LEX) receives AC power from the system power source or
power distribution strip (PDS) in the rack. A 6-ft. (1.82-m) adapter cable connects the
extender’s power adapter to the PDU. The REX requires AC power from a sour ce within
a 6-ft. (1.82-m) range from the keyboard/mouse connection point.

3: Configurations and Cabling
NUMAlink Cabling in Ring Topologies
The basic Silicon Graphics Prism uses a type of network configuration that is referred to
as a ring topology. As the name implies, the network connection between the base
compute module, graphics module, and optional CPU expansion or CMPX modules
forms a ring. A message is passed around the ring until it reaches its destination. The data
flow of this ring topology flows in both directions, enabling the modules to have direct
connection to two other modules and providing an alternative path if a connection fails
between two modules.
The Silicon Graphics Prism system may also be configured in routed configurations,
which are described in “NUMAlink Cabling in Routed Systems” on page 65.
The bisection bandwidth per node depends on the number of modules on the ring, as
well as what type of modules they are; the bisection bandwidth per node is greatest when
there are only two modules on the ring. See Table 3-3.
Table 3-3 Bisection Bandwidth of Ring Topology
Module Count Bisection Bandwidth
2 3.2 GB/s/node
3 (with 2 pipes) 2.13 GB/s/node
