EISA SCSI Master(r) II Accelerates system performance with RISC-based SCSI I/O --------------------------------------------------------------------------- KIT HIGHLIGHTS * Features the AHA(r)-2742AT EISA-to-Fast SCSI 32-bit bus master host adapter * Accelerates EISA system performance with PhaseEngine(tm) RISC processor and Adaptec(r) 7700 Family Manager Set software * Supports up to 14 SCSI-2 devices on a single TwinChannel(r) host adapter * Includes Adaptec EZ-SCSI software for quick and easy installation * Features application software for SCSI Tape Backup, Photo CD Viewer and CD Player * Supports DOS/Windows, Windows NT, OS/2(r) , NetWare(r) and UNIX(r) operating systems --------------------------------------------------------------------------- OVERVIEW The EISA SCSI Master II kit is the high-performance EISA solution for demanding, multitasking applications such as client/server networking, engineering CAD/CAM and transaction processing. Powered by the Adaptec-designed 8 MIPS PhaseEngine RISC processor, the AHA-2742AT maximizes EISA system performance by fully utilizing 32-bit bus mastering at 33 Mbytes per second. The Adaptec 7700 Family Manager Set software further optimizes system performance. The EISA SCSI Master II kit assures compatibility with popular applications through Adaptec's I/O operating environment support under DOS/Windows, Windows NT, OS/2, NetWare and UNIX operating systems. --------------------------------------------------------------------------- KEY BENEFITS Higher performance through innovative design The AHA-2742AT is based on the Adaptec-designed PhaseEngine processor, a dedicated RISC 8 MIPS sequencer, which automates SCSI commands, reduces SCSI host interrupts and decreases SCSI command processing time by 90%. This fourth-generation EISA host adapter increases I/O throughput up to 55% over previous generation host adapters. Using dynamic command processing, the Adaptec 7700 Family Manager Set software enables the AHA-2742AT host adapter to process hundreds of SCSI requests simultaneously, maximizing performance in multitasking environments. Expanded storage capabilities The AHA-2742AT features Twin-Channel SCSI, allowing connection of up to 14 SCSI-2 devices on a single host adapter. With only one EISA slot, you can accommodate a disk array for fault tolerance, employ optical devices for research and use a tape drive for backup, resulting in optimum storage expansion flexibility. Easy SCSI installation The EISA SCSI Master II kit includes Adaptec EZ-SCSI software to make SCSI installation quick and easy. Adaptec EZ-SCSI software determines what hardware is present and automatically modifies the CONFIG.SYS and AUTOEXEC.BAT system files. Support for popular SCSI applications SCSI Tape backup, Photo CD Viewer and CD Player applications are included in the EISA SCSI Master II kit. SCSI Tape Backup lets you select the volume, directory or file for backup with "point-and-click" simplicity using the Windows-based graphical directory tree. Multiple backup methods, including normal, incremental and differential, allow you to backup all files or only those that have been created or modified since the last backup. With the Photo CD Viewer application, you can view photographic images stored on CDs and edit them directly into your multimedia applications. The CD Player application lets you access and play CDs using Windows screen controls similar to those on your home stereo. Compatibility and reliability for EISA server applications The AHA-2742AT board uses a fully integrated design which dramatically increases mean time between failures (MTBF) to 110,000 hours, an 80% increase over previous generation Adaptec EISA host adapters. To ensure compatibility with popular software and high-performance applications, Adaptec has tested the AHA-2742AT with hundreds of computer platforms running major operating systems, storage management, fault tolerance and tape backup applications. Adaptec's manufacturing facility has earned ISO-9002 international certification which ensures compliance to a high-level of product quality in production, testing and service. IOware(r) products by Adaptec Adaptec's IOware products combine hardware and software technology into solutions that are critical to ensuring the level of performance required for today's data- and graphics-intensive applications. --------------------------------------------------------------------------- A COMPLETE KIT The EISA SCSI Master II kit includes: * AHA-2742AT EISA-to-Fast SCSI host adapter with floppy controller * Adaptec EZ-SCSI software for DOS and Windows, including application software for Photo CD Viewer (Magic Lantern(tm) CD Player and SCSI Tape Backup (Backup Basics) * Adaptec 7700 Family Manager Set software (Windows NT, OS/2,NetWare and UNIX) * ASW-C274 EISA configuration utility * Device support for hard disk, removable, MO, CD-ROM, Photo CD, tape, DAT, scanner and Floptical(r) drives * AHA-2740/42 User's Manual * Adaptec EZ-SCSI User's Manual * Adaptec 7700 Manager User's Manual * Internal SCSI ribbon cable (external cable not included) --------------------------------------------------------------------------- TECHNICAL SPECIFICATIONS Computer Bus: EISA Interface Protocol: Bus master DMA Host Transfer Rate: Up to 33 Mbytes/sec burst rate on EISA bus SCSI Transfer Rate: 10 Mbytes/sec synchronous burst on the SCSI bus (Fast SCSI) 5 Mbytes/sec synchronous burst on the SCSI bus 3 Mbytes/sec asynchronous on the SCSI bus Device Protocol: SCSI-2 Advanced SCSI Features: Fast SCSI dynamic/command processing (supporting 255 simultaneous commands), scatter/gather, tagged queuing, multitasking, disconnect/reconnect, synchronous and asynchronous data transfer Electrical Drivers: Single-ended Bus Width: 32-bit Device Support: Up to 14 SCSI-2 devices Two floppy drives (51/4" or 31/2") I/O Operating System Support: DOS/Windows, Windows NT, Windows for Workgroup, OS/2, NetWare, SCO(r) UNIX, UnixWare Physical Dimensions: 7"x 5" (17.8 cm x 12.7 cm) I/O Hardware: Internal and external SCSI connectors, 50-pin, high density Operating Temperature: 0° C (32° F) to 55° C (131° F) Storage Temperature: -40° C (-40° F) to 75° C (167° F) Relative Humidity: 10% to 95% noncondensing --------------------------------------------------------------------------- Adaptec, Inc. 691 South Milpitas Blvd. Milpitas, CA 95035 408-945-8600 Literature: 1-800-934-2766 Ordering Software: 1-800-442-7274 (USA and Canada) or 408-957-7274 Interactive FAX: (408) 957-7150 Internet ftp server: ftp.adaptec.com World-Wide Web: http://www.adaptec.com CompuServe: GO ADAPTEC Adaptec USA Bulletin Board: 408-945-7727 (up to 28,800 baud, using 8 bits, 1 stop bit, no parity) --------------------------------------------------------------------------- Copyright (c) 1993, 1994 Adaptec, Inc.
