SPARCserver 20 System

The SPARCserver 20 system, introduced in 1994, is designed to be a workgroup NFS file server or a database server in an office environment. It is based on the same MBus and SBus technologies as the SPARCserver 10 system. Performance is increased over the SPARCserver 10 by using faster MBus and SBus technology, and faster SPARC modules. The SPARCserver 20 system has increased computing and network performance.

The SPARCserver 20 system is available in three uniprocessor configurations and three multiprocessor configurations.

The uniprocessor configurations are:

• Model 50--50 MHz SuperSPARC processor

• Model 51--50 MHz SuperSPARC processor and 1 Mbyte SuperCache

• Model 61--60 MHz SuperSPARC processor and 1 Mbyte SuperCache

• Model 71--75 MHz SuperSPARC processor and 1 Mbyte SuperCache

• Model 151--one 150 MHz HyperSPARC processor and 0.5 Mbyte external cache

The multiprocessor configurations are:

• Model 502MP--two 50 MHz SuperSPARC processors

• Model 514MP--four 50 MHz SuperSPARC processors and 1 Mbyte SuperCache

• Model 612MP--two 60 MHz SuperSPARC processors and 1 Mbyte SuperCache

• Model 712--two 75 MHz SuperSPARC processors and 1 Mbyte SuperCache

• Model 152MP--two 150 MHz HyperSPARC processors and 0.5 Mbyte of external cache
