Ultra 80

The Ultra 80 is a fairly large (445 mm (17.5 in) high, 255 mm (10.0 in) wide and 602 mm (23.7 in) deep) and heavy (29.5 kg (65 lb)) computer workstation in a tower enclosure from Sun Microsystems. The Ultra 80 was launched in November 1999 and shipped with Solaris 2.5.1. The Ultra 80 was available in a variety of different specifications with one (model 1450), two (model 2450) or four (model 4450) 64-bit UltraSPARC-II CPUs and up to 4 GB of RAM. When released, the Ultra 80 was Sun's highest performance workstation.

The Ultra 80 is similar to the lower-cost Sun Ultra 60, but is somewhat larger and supports more CPUs and memory. The Ultra 80 may be rack-mounted using an optional rack-mount kit (X9627A or 560-2548) although they are generally not rack-mounted, since the Ultra 80 was designed as a workstation rather than a server. Details can be found in the Sun Ultra 80 Rack Mount Installation Guide. The Enterprise 420R contains an Ultra 80 motherboard in a specialized rackmount case with custom power supplies and other parts.

The Ultra 80 is no longer sold new and was replaced by the Ultra 45, although the Ultra 45 can only take two CPUs, rather than the four of the Ultra 80. The last order date for the Ultra 80 was July 2002 and the last model to be shipped was in October 2002, so it is now considered by Sun to be end of life.
