The Onyx2, code name Kego, is a family of visualization systems developed and manufactured by SGI, introduced in 1996 to succeed the Onyx. 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 IRIX 6.4 or 6.5.
