About the Sun Enterprise 220R Server

The Sun Enterprise 220R server is a high-performance, shared memory, symmetric- multiprocessing system. It is designed around Sun’s high-speed Ultra Port Architecture (UPA) cross-bar system interconnect and Sun’s UltraSPARCTM II processors, to deliver outstanding overall system performance.

The system is housed in a standard Electronic Industries Association 310 (EIA 310) specification-compliant rackmountable enclosure. The enclosure measures 7.00 inches high, 17.25 inches wide, and 27.25 inches deep (17.8 cm x 43.8 cm x 69.2 cm). The system has a maximum weight of 65 lb (34 kg). You may rackmount up to nine systems in an empty 72-inch (182.80-cm) EIA-compliant cabinet, such as the Sun™ StorEdge Expansion Cabinet.

Processing power is provided by up to two modular UltraSPARC II CPUs, with up to 4 Mbytes of local high-speed external cache memory. The system UPA’s clock rate synchronizes automatically to the clock rate of the installed CPUs, and the UPA bus operates at a clock rate that is a ratio of the speed of the CPU modules. For more information about CPU modules, see “About CPU Modules” on page 67.
