Origin 2000 systems and Onyx2 InfiniteReality2 systems consist of a variety of standard and optional equipment. Each rack or peripheral device and each system configuration has unique physical characteristics.
Table 3 provides physical specifications for Origin 2000 racks, MetaRouters, Onyx2 InfiniteReality2 racks, Onyx2 InfiniteReality2 multirack systems, SCSI RAID cabinets, Origin Fibre Channel racks, O2 workstations, and workstation monitors. The following subsections describe the system components in detail. All specifications in Table 3 are per rack unless otherwise noted.
NOTE: An above-the-floor cable trough connects the two rows of equipment in 256-processor Origin 2000 multirack systems. The two cable troughs restrict access to the area between the rows of equipment. Sites with 256-processor systems must maintain a 36-inch (892-mm) separation between the computer room walls and the end of each row of equipment to meet maintenance and safety requirements. The shaded area in Figure 16 represents these above-the-floor cable troughs.
Each Origin 2000 rack can contain a maximum of two modules. Each module can contain from one to four node boards, with up to two superscalar processors (CPUs) on each board. This means that each Origin 2000 rack may contain between 2 and 16 CPUs. Origin 2000 multirack systems with more than 64 CPUs (4 full racks) require a MetaRouter, which is also modular and mounts in a rack. The maximum multirack system configuration is 256 CPUs. This configuration consists of 16 full racks with 32 modules and 128 node boards, and 4 MetaRouter racks that contain 2 modules each. Each module inside the MetaRouter houses eight router boards.
Figure 14 illustrates a single Origin 2000 rack. Figure 15 illustrates the MetaRouter. Figure 16 illustrates the possible Origin 2000 multirack system configurations.
NOTE: CrayLink cables connect MetaRouters to Origin 2000 racks. Braided straps are also attached between MetaRouter racks to provide ground continuity.

The following subsections provide configuration and rack placement information about available Onyx2 InfiniteReality2 systems. Figure 17 illustrates the Onyx2 InfiniteReality2 rack. Figure 18 illustrates the Onyx2 InfiniteReality2 rack and multirack system configurations.
The Onyx2 InfiniteReality2 rack system is a single-rack computer system that contains one compute module and one graphics insert module. This compute module contains between two and eight CPUs. The graphics insert module, which is located above the compute module, contains up to two graphics pipelines and up to six raster manager boards with associated display boards. Refer to Figure 17.
The Onyx2 InfiniteReality2 multirack systems range in configurations from 9 CPUs, 3 graphic pipelines, and 8 raster managers configured into two racks to a maximum configuration consisting of 128 CPUs, 16 graphic pipelines, and 64 raster managers configured into 17 racks (refer to page 40 and page 41).

Figure 18. Onyx2 InfiniteReality2 System Configurations
The Onyx2 InfiniteReality2 system may be located on a raised or nonraised floor adjacent to an Origin 2000 system if adequate space is available. Cable length restrictions do not allow more than two Onyx2 racks to be located adjacent to the Origin 2000 racks. Sites with systems configured with more than four Onyx2 racks (two on each end of an Origin 2000 row of racks) must locate the racks behind the Origin 2000 racks as shown in Figure 19. Other floor layouts are possible; contact Site Planning for additional floor layouts and floor cutout templates.
NOTE: Cable guides are used to route cables between Onyx2 racks and Origin 2000 racks at sites with nonraised floors. Contact your SGI account representative for ordering information.

The SCSI RAID rack is an air-cooled disk storage chassis that is capable of housing up to four RAID chassis assemblies. Each RAID chassis assembly can house up to 20 disk drive modules. Figure 20 illustrates the SCSI RAID rack.

The Origin Fibre Channel rack contains up to 11 FibreVault disk enclosures or up to 5 Fibre Channel RAID enclosures. Each FibreVault disk enclosure can contain up to 10 non-RAID disk modules. Each Fibre Channel RAID enclosure can contain up to 10 RAID disk modules.
Figure 21 illustrates the Origin Fibre Channel rack.

The O2 workstation provides monitoring and control capabilities for the
Origin 2000 system and the Onyx2 InfiniteReality2 system. The O2 workstation consists of the workstation chassis with internal CD-ROM drive, monitor, keyboard, mouse, cables, CD-ROM disks, and documentation. Contact your account representative to purchase the optional camera and optional 30 in. x 48 in. (762 mm x 1219 mm) table for the workstation. You may also purchase additional data equipment for your particular application. Figure 22 illustrates the O2 workstation. Figure 23 illustrates the 20-in. color O2 workstation monitor.
NOTE: If the workstation will be connected to a system with more than 64 CPUs, the IRISconsole option must be added to the workstation.
