SunTM Dual Fast Ethernet + Dual SCSI PCI Adapter is a 33/66 MHz combo adapter providing two wide-Ultra-SCSI 2 (80 MB/s) channels and two Fast Ethernet channels on one EPCI (32/64-bit,33/66 MHz) card.

Fast Ethernet Interfaces features include:

• Support of two independent 10 Mbps (10 Base-T) or 100 Mbps (100 Base-Tx) Ethernet channels through a dual RJ-45 connector

• Utilization of two 66 MHz, 64 bit Cassini ASICs for improved secondary PCI bus operation

Ultra 2 Interfaces features include:

• Support of two independent 80 MBytes/sec Ultra2 SCSI channels through a dual, VHDCI ( very high-density cable interconnect)

• Support of both SE (single ended)and LVD (Low Voltage Differential) SCSI Bus driver type

PCI Bus Interface features:

• Support of universal PCI slot (3.3V or 5V I/O)

Ultra2 SCSI introduced Low Voltage Differential signaling (LVD or LVDS) that supports cable lengths up to 12 meters. Single-ended SCSI uses a data line and ground. Both HVD SCSI and LVD SCSI use data low and data high lines to increase transmission distance. However, LVD requires less power and is less costly, because the transceivers are built into the controller chips.

Fast Ethernet is a natural extension of the existing 10 Mbps Ethernet technology. It is backward compatible with existing networking protocols, media and standards. It is cost-effective, easy to deploy, and offers 10 times the speed of 10Base-T Ethernet at a low cost of ownership.

The Fast Ethernet architecture allows scalable performance up to 100 Mbps,meaning that higher throughput of the workstation at the sending or receiving end directly translates into more performance through the network.

The growing importance of LANs and the increasing demand for data in a variety of forms are fueling the need for high-bandwidth networks. Information systems (IS) managers must consider extending or replacing traditional network technologies with new, high-performance solutions.

As a simple evolution of the familiar IEEE 802.3 Ethernet standard, 100Base-T Fast Ethernet preserves the core structure of Ethernet and includes support for up to 100Mbps and the most widely used cabling schemes. It can be easily integrated with existing 10 Mbps Ethernet networks to provide ten times more network throughput to the desktop at a minimal incremental cost. Its interoperability with other low- and high-bandwidth networking technologies offers network administrators more flexibility in structuring high-speed LANs and WANs.

100BASE-T Fast Ethernet, a technology designed to provide a smooth transition from 10Base-T Ethernet, to high-speed 100-Mbps performance. A second option for increasing peripheral connectivity is the fast/wide SCSI-2 interface. A single card that supports both 10/100 Mbps Ethernet and fast/wide SCSI-2 connections give the end users the best performance at the lowest cost, in addition to the saving of a expansion slot in the system.
