The Sun Enterprise 1 system is the first member of a new class of workstations based on the UltraSPARC-I processor and is designed to deliver balanced system performance.
The Sun Enterprise 1 system can be used as a high capacity NFS server for medium to large workgroups (50 to 100 users). It is designed for reliability, availability, and serviceability. It enables easy access to replace disk drives, SIMMs, and graphics cards.
The Sun Enterprise 2 system is a multiprocessor system based on the UltraSPARC-I processor. It is standard with Fast/Wide SCSI and Fast Ethernet, which enables the data throughput capability of this system to include the disk I/O and the network traffic. The system also has a 64-bit SBus running at 25 MHz giving maximum SBus throughput.
The Sun Enterprise 2 system can be used as an NFS server for mid- to large- sized workgroups.
The Ultra SPARC CPU is matched by a very high performance crossbar-switched interconnect that can move data at peak rates of 1.3 Gbytes/second. This interconnect, the Ultra Port Architecture (UPA), is the key to providing the greatly enhanced memory bandwidth. Both the Sun Enterprise 1 and 2 systems have a 64-bit SBus running at 25 MHz giving maximum SBus throughput.
The architecture was designed to be fully compatible with previous generations of workstations so that all Solaris operating environment applications can run unchanged.
