General
SGI O2 front with classic cube design.
Silicon Integrated Scsi Components
The Silicon Graphics O2 (codename 'Moosehead') may be considered a successor to the Indy line of desktop workstations. It is also placed at the lower end of the Silicon Graphics product line and like the Indy the O2 features integrated video capabilities. The O2 like the Indy was designed with a focus on video and multimedia applications.
In 2001 the Silicon Graphics O2+ extends and updates the original O2 series from 1996, but offers no change in the underlying architecture. To let SGI speak here: 'This workstation is a value-rich version of the Silicon Graphics O2 visual workstation. It has all the benefits and integrated features of the O2 workstation, plus twice the system memory, and two times the system disk capacity, a new high-performance processor, and a new purple color.'
Twice the system memory and disk capacity refers to the basic system configuration. So aside from being available with other CPU options the O2+ is technically an O2.
Architecture Overview
Silicon Integrated Systems
What sets the O2 aside from other systems designed by Silicon Graphics is it's Unified Memory Architecture (UMA). At the core of the system architecture is the Memory & Rendering (MRE) ASIC which includes direct paths to all subsystems of the O2 including CPU, Memory, I/O, compression, display and imaging.
Silicon Integrated Scsi Solutions
Unlike other Silicon Graphics computers the O2 does not have graphics as an optional part. The O2 graphics hardware is highly integrated in to the systems core components. This makes the O2 the only Silicon Graphics system which cannot be ordered without graphics installed and also the only one where there is no choice of graphics options.
