The highest capacity workgroup servers are presented first.
The Sun Enterprise 150 server system is a tower workgroup server based on the 167 MHz UltraSPARC(TM) microprocessor. It has the following features:
Autosensing 10/100 Mbps Fast Ethernet
10 Mbps Ethernet
20 Mbyte/second Fast/Wide SCSI-2 peripheral interface
ECC-protected memory
Internal disk array with up to twelve hot-plugable disks supporting RAID 0 (disk striping), RAID 1 (disk mirroring), and RAID 5 (hot spares) providing 48 Gbytes of disk capacity (based on 4 Gbyte disk drives)
1.44 Mbyte diskette drive
644 Mbyte CD-ROM drive
The Sun Enterprise 150 server system is ideal for an NFS server because it is a high-end workgroup server with high I/O performance and fast system throughput. Figure 2-4 shows a front view of the server.
For additional disk storage, you can attach either the Sun StorEdge UniPack or the Sun StorEdge MultiPack to the server. If you need greater amounts of disk storage, use the SPARCstorage Array to the server. For a backup device, use the SPARCstorage Library, which olds ten cartridges in a removable magazine for an average total capacity of 140 Mbytes.

Figure 2-5shows a front view of the Sun Enterprise 250 system.
The Sun Enterprise 450 system server, based on the UltraSPARC-II(TM) processor, is designed for mid-range server markets that require large amounts of local disk storage with fast or multiple I/O channels to clients or to the network.
Software features are:
Support for RAID 1 (disk mirroring), RAID 3 (striping data and parity across drive groups) and RAID 5 (hot spares for FC-AL disk drives)
System performance and configuration monitors
Automated hardware failure notification
Error and panic logging
Temperature sensing and fan control
Backup power supply failure detection
Hot sparing support
Automatic fault detection, response, and recovery
Logging file systems
Hardware features are:
10 PCI slots supporting up to 10 full size PCI cards (seven regular PCI slots and three enhanced PCI slots)
Up to sixteen SIMM slots, which support 32, 64, 128 or 256 Mbyte SIMMs totalling up to 4 Gbytes of memory capacity
10/100 Mbit Ethernet
20 Mbyte/second Fast Wide SCSI
Up to four CPU modules (UltraSPARC-II)
Up to twenty hot swappable FC-AL disks and up to two 1.6-inch high SCSI disks that provide up to 84 Gbytes internal storage
Up to 6 Terabytes of external disk storage
1.44 Mbyte diskette drive
644 Mbyte CD-ROM drive
Two 5 1/4-inch bays for optional tape backup
Two high speed synchronous/asynchronous serial ports
Up to three redundant hot swapable power supplies, which can be added one at a time to improve reliability and provide growth as needed
Supports rack mounting allowing the system to integrate easily into a computer room environment
You can attach up to two external tape devices or a single size or twelve drive Sun StorEdge MuliPack to the SCSI port. You can attach additional tape or disk devices by installing PCI host adapter cards. If you require large amounts of disk storage, you can also attach the Sun StorEdge A3000 subsystem to the system that provides a reduntant array of inexpensive disks (RAID).
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.
Figure 2-7 shows a front view of the Sun Enterprise 1 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
Figure 2-8 shows the front view of the SPARCserver 20 system.
