Spider: A High-Speed Network Interconnect
January/February 1997 (vol. 17 no. 1)
pp. 34-39
The SGI SPIDER chip provides a high-speed, reliable switching network with a flexible interface and topology suitable for a variety of high-end applications. Six full-duplex ports and a nonblocking internal crossbar can sustain a data transfer rate of 4.8 Gbytes/sec, either between chips in a single chassis or between remote chassis over cables up to 5 meters long. Messages of arbitrary length travel over four independent virtual channels with 256 levels of priority, and are protected by CCITT-CRC with hardware retry. These features make the SGI SPIDER well suited to serve as an interprocessor communication fabric, a distributed graphics switch fabric, or a central switch for high-end networking applications.
