ATTO Technology Delivers Speed, Efficiency and Reliability with Launch of Ultra3 SCSI Host Adapter.AMHERST, N.Y.--(BUSINESS WIRE)--November 11, 1999-- New Host Adapter Also called a "controller" or "host bus adapter," it is a device that connects one or more peripheral units to a computer. It is typically an expansion card that plugs into the bus. IDE and SCSI are examples of peripheral interfaces that call their controllers host adapters. See host. is an Ultra3 Connectivity Solution Offering High Performance Capabilities to Data-Intensive Environments ATTO Technology, Inc., a worldwide manufacturer of SCSI SCSI in full Small Computer System Interface Once common standard for connecting peripheral devices (disks, modems, printers, etc.) to small and medium-sized computers. SCSI has given way to faster standards, such as Firewire and USB. and Fibre Channel storage connectivity solutions, will announce at Fall Comdex'99, November 15 - 19 in Las Vegas, NV, the launch of the ATTO Quintillionth (10 to the -18th power). See space/time. ExpressPCI UL3D, a high-performance SCSI connectivity solution for data-intensive environments. The ExpressPCI UL3D is an Ultra3 SCSI dual channel host adapter designed to deliver high levels of throughput, efficiency and reliability to demanding I/O (Input/Output) The transfer of data between the CPU and a peripheral device. Every transfer is an output from one device and an input to another. See PC input/output. I/O - Input/Output applications. The Ultra3 SCSI host adapter meets the growing need for premium SCSI connectivity solutions and integrates easily into existing SCSI environments. Features include double transition clocking, for combined data transfer rates of up to 320 MB/sec. (160 MB/sec. per channel), as well as domain validation to ensure accurate data throughput and increase user satisfaction. The Ultra3 SCSI host adapter also incorporates cyclical redundancy checks (CRC (Cyclical Redundancy Checking) An error checking technique used to ensure the accuracy of transmitting digital data. The transmitted messages are divided into predetermined lengths which, used as dividends, are divided by a fixed divisor. ) to verify data integrity. "The addition of the ExpressPCI UL3D to ATTO's family of SCSI host adapters will allow users of data-intensive applications such as, digital video, pre-press, broadcast, digital content creation The development of newsworthy, educational and entertainment material for distribution over the Internet or other electronic media. See DAMS. and imaging applications to take their applications to new levels of speed, efficiency and reliability," states ATTO President Timothy Klein. "We look for the ExpressPCI UL3D to make a significant impact in a variety of data-intensive markets. In addition to increased throughput and data integrity demanded by high performance, high-end applications, the ExpressPCI UL3D provides users with a seamless, reliable migration path within existing SCSI environments." "The combination of the SCSI Trade Association's requirements for Ultra3 and ATTO exclusive features delivers an Ultra3 SCSI connectivity solution with leading-edge management features, improving data reliability while optimizing interoperability," added Klein. "At double the speed of Ultra2 SCSI, the ExpressPCI UL3D incorporates the advantages of Ultra3 SCSI, while providing established ATTO advantages, such as Advanced Data Streaming (ADS ) technology." The Ultra3 host adapter also features ATTO's proprietary Advanced Data Streaming (ADS(TM)) Technology, which allows for controlled acceleration of data transfers in order to move large amounts of data faster and more efficiently. ADS Technology ensures smooth data flow by utilizing only one-third of the system bandwidth used by other host adapters. The remaining bandwidth becomes available for additional inter-system communication and other system applications. Other features of the Ultra3 SCSI host adapter include: - Dual independent SCSI channels, each with an internal and external connector - Fully compatible with the Ultra160/m initiative - Low Voltage Differential (hardware) Low Voltage Differential - (LVD) A method of driving SCSI cables that will be formalised in the SCSI-3 specifications. LVD uses less power than the current differential drive (HVD), is less expensive and will allow the higher speeds of Ultra-2 SCSI. LVD requires 3. SCSI signaling - Connectivity for up to 30 SCSI IDs (15 IDs per channel) - 12 meters of cabling length - 33/66 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. compatible - 32/64-bit PCI (1) (Payment Card Industry) See PCI DSS.

FAP Carlos Ciriani Santa Rosa International Airport in Tacna, Peru. Tagged Command Queuing (TCQ) is a technology built into certain ATA and SCSI hard drives. - Multiple Initiator Support - Support for Disconnect/Reconnect - Support for Multiple Block Sizes - Bus Mastering Capability About ATTO Technology, Inc.
