UltraSPARC System Implementations

There are five UltraSPARC I- and UltraSPARC II-based system implementations to discuss. The most recent and simplest is the highly integrated uniprocessor UltraSPARC IIi, a successor to the microSPARC. The initial UltraSPARC workstations are based on a simple UPA configuration. An expanded UPA configuration is used in the workgroup server systems. The Enterprise Server range uses a Gigaplane bus to link large numbers of CPUs and I/O buses. The E10000 Starfire uses an active backplane crossbar to support the very biggest configurations.

The Ultra 5 and Ultra 10

The UltraSPARC IIi provides a highly integrated design for building low-cost systems in the same way as its microSPARC predecessor. The CPU chip includes ...
