In addition to flexibly scaling memory, CPU, I/O, and graphics capability, the Silicon Graphics® Onyx4™ UltimateVision™ family comes with a series of simple expansion modules to expand memory and I/O even further for those customers who need to.
A snap-together approach to system architecture allows you to easily add these expansion modules to your Onyx4 system to match your requirements precisely. Just choose the expansion modules that your applications require:

Scalable Graphics Compositor:
The Scalable Graphics Compositor is a zero-latency device that combines two to four input digital video streams into a single digital or analog video output stream. By combining the video-input streams, the 2U (3.5 inches) high Scalable Graphics Compositor enables the graphics power of each graphics pipe to combine and deliver incredible performance. It is 2U (3.5 inches) high and works solely with the InfinitePerformance graphics pipes.
