Ultra 80
The Sun Microsystems Ultra 80 is a computer workstation that shipped from November 1999 to 2002.
Its enclosure 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)) tower design. At launch, it shipped with Solaris 7, and was available in a variety of different configurations, 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. Although it was designed as a workstation rather than a server, it may be rack mounted using an optional kit. The Enterprise 420R is a server product based on the Ultra 80 motherboard in a specialized rack-mountable chassis, with custom power supplies and other parts more appropriate for server applications.
The last order date for the Ultra 80 was July 2002 and the last model stopped shipping in October 2002. The later Ultra 45, introduced in 2006, supports a maximum of two CPUs, rather than the four of the Ultra 80.
The Ultra 80 shipped with Solaris 7 Update 8/99, and is capable running later versions of Solaris through Solaris 10 (Oracle Solaris 11 dropped support for UltraSPARC II, III and IV processors), as well as Linux and NetBSD. The Ultra 80 cannot run Microsoft Windows directly, although an internal PCI card (SunPCi II pro and similar) from Sun could be fitted to allow the use of Windows.
Full specifications can be found on the Sun web site.
Although only sold with either one, two, or four CPUs, the use of three CPUs is a supported configuration. The CPUs run at 450 MHz and have 16-KB data and 16-KB instruction cache on chip with a secondary 4-MB external cache. The X1195A is the part number of one of the CPUs. Each CPU has an integrated floating point processor.
The Ultra 80 uses 144-pin 5V 60-ns DIMM memory modules of either 64 or 256 MB, which should be installed in sets of four identical DIMMs. There are 16 DIMM sockets, so it is possible to fit up to 4 GB with sixteen 256 MB modules. The memory bus is 576 bits wide; 512 bits are used for data and 64 bits for error correction. The specifications list a maximum throughput of 1.78-GB/s. Performance is improved if 2-way interleaving is used (giving 512 MB or 2 GB) and maximum performance is achieved with 4-way interleaving, in which case all 16 memory slots would be used, providing the machine with 1 GB or 4 GB of RAM.
