Origin 3000 / Onyx 3000

Introduction

General

The Onyx/Origin 3000 series is a family of modular graphics supercomputers and servers. They are successors to the Onyx 2 and Origin 2000 line. The systems are not built from single boards that are plugged into a back- or midplane like the SGI classics Onyx or Challenge (L/XL) used to. The Onyx/Origin system components are divided into rackmountable bricks that are connected with cables and router bricks integratet into a complete system.

Basic server models which appear in SGI marketing papers are Origin 3200, 3400 and 3800 as well as the cluster solution Origin 3200C. Graphics supercomputers appearing in the same way are Onyx 3200, 3400 and 3800.

Compute

C-Brick (Compute Node)

General

C-Bricks contain the processors and memory of SGI Origin/Onyx 3000 systems. Each C-Brick contains CPUs of a specific type (all the same), but it is allowed to mix C-Bricks with different CPU types in a system though. The Compute Node contains one Printed Circuit Board, that includes the node electronics, L1 controller, power regulators and memory sockets. The processors are housed on seperate PIMM boards, that also contain the second level cache.

General

R-Bricks ("routers") are required to build a system from more than 2 C-Bricks. If a system contains only a single C-Brick obviously no router is required, if there are two C-Bricks in a single system they can be directly connected.

Different router versions:

  • 6-port router - used to support up to 32 processors as in Origin 3400 or Onyx 3400 systems
  • 8-port router - used to support up to 128 processors as in Origin 3800 or Onyx 3800 systems
  • metarouter - for systems over 128 processors

D-Brick (Disk Brick)

General

The D-Brick is a harddisk enclosure for use in Origin/Onyx 3000 systems. JBOD ("Just a Bunch Of Disks") storage:

  • 12 dual-ported fibre channel sleds (hot-pluggable)
  • 2 hot-pluggable 400W power supplies and redundant fans

The basic functionality of the drives is controlled by a Enclosure System Interface / Operator module which is accessible from the back of the system. It shows status information for the drives (as a whole) and allows to switch the brick into service mode.

Instead of that solutions like the TP-9100 storage system can also be used, if advanced features like RAID are required.

Brick Specs

Size:                   4U
Front:                  12 slots for disks in drivesleds
Back:                   1 ESI/ops panel
                        2 LRC modules
                        2 powersupply/cooling modules 

System Controller

The L1 system controller is part of each brick (except D-Brick) and reports status information to the L2 system controller which has a touchscreen panel to display information and control the systems operation.

A L2 system controller is placed only in racks that contain C-bricks. It is inside the rack just below the "roof" and doesn't occupy any place that could be used by bricks otherwise. The display attached to the front door is also a touch display.

Size:                   0U
Connectors:             1 PWR
                        1 ICMB
                        1 RJ45 10/100Base-T Ethernet
                        1 LCD display
                        4 USB L1 ports
                        1 DB9 console port
                        1 DB9 modem port

Power Bay / Power Distribution Unit / Power Distribution Strip

These parts provide the system with the required power. The Power Bay contains up to 6 hot swappable powersupplies and provides the Bricks of the system with power (48VDC). It is connected to a wall outlet using a Power Distribution Unit.

width:     44,45 cm / 17.5"
height:    12,95 cm /  5.1" (3U)
depth:     62,23 cm / 24.5"

weight:    ? kg / 72 lbs

The Power Distribution Unit (3400 and 3800 configurations) and Strip (all) allow to distribute power to system components that have their own powersupplies and don't have to rely on power provided by the Power Bays (such as the D-Brick for example).

Chassis

General

Airflow

All modules ("Bricks") of Onyx/Origin 3000 systems have the air intake and in most cases even the cooling fans on the front. The cool air is blown from the front through the module and out to the back where the cables are attached. All modules must provide self-cooling with airflow from front to rear as the racks do not have any cooling facilities of their own.

Short Rack

The short rack offers 17U of configurable space and features 19-inch EIA standard mounting rails.

width:     64,77 cm / 25.5"
height:    91,44 cm / 36.0"
depth:     91,44 cm / 36.0"

weight:    ? kg / ? lbs

Tall Rack

The tall rack offers 39U of configurable space and features 19-inch EIA standard mounting rails. It is used for configurations with more than 8 processors or.

width:      76,20 cm / 30.0"
height:    188,60 cm / 74.25"
depth:     130,80 cm / 51.50"

Operating System

Choosing an operating system.

The Origin 3000 line is supported in IRIX 6.5 beginning with IRIX 6.5.15 up to the final release IRIX 6.5.30. Origin 3900 support was added in IRIX 6.5.19.

Regardless of the system configuration it is always recommended to use IRIX 6.5.30.
