SGI, introduced in 1996 to succeed the
Onyx
Onyx primarily refers to the parallel banded variety of chalcedony, a silicate mineral. Agate and onyx are both varieties of layered chalcedony that differ only in the form of the bands: agate has curved bands and onyx has parallel bands. The c ...
. The Onyx2's basic system architecture is based on the
Origin 2000 servers, but with the inclusion of graphics hardware. In 2000, the Onyx2 was succeeded by the
Onyx 3000, and it was discontinued on June 27, 2003. These systems run either
