SCSI CARD 2940U2W Assured Ultra2 SCSI Performance and Maximum Configuration Flexibility Overview As the power of applications, processors, and storage devices increase, high-end computer users are seeking ways to optimize their system performance. The SCSI Card 2940U2W provides the throughput speed, flexibility, and compatibility required to optimize today's workstations and PC servers. It provides Ultra2 SCSI data transfer rates up to 80 MByte/sec and optimizes the performance of all peripherals attached to the card with SpeedFlex technology. By providing 4 connectors and extended cable lengths, the SCSI Card 2940U2W also allows for maximum system configuration flexibility. bus segment. Without SpeedFlex technology, any Fast or Ultra SCSI peripheral connected to an Ultra2 SCSI bus will drop the maximum burst rates of all peripherals on the bus to the Ultra SCSI performance level. Maximum Configuration Flexibility The SCSI Card 2940U2W offers maximum configuration flexibility by quadrupling the allowable length of the SCSI bus to a maximum of 12 meters. This feature is particularly useful when configuring external storage and clustered servers. In addition, the SCSI Card 2940U2W provides four connectors, which can all be used simultaneously, and four SCSI cables. The cables enclosed with the kit include a terminated Ultra2 cable and an internal-to-external 50-pin cable, which improve ease of installation and enable a wide variety of system configuration options. Highest Quality, Maximum Compatibility The latest in a long line of PCI-to-SCSI cards from Adaptec®, the SCSI Card 2940U2W has been thoroughly tested with over 350 systems and peripherals to deliver the utmost in reliability and compatibility. As the industry leading manufacturer of SCSI cards, Adaptec assures the widest possible compatibility, now and in the future. 80 80 Product Highlights s 80 MByte/sec data burst rates on the Ultra2 SCSI bus SpeedFlexTM technology which allows simultaneous operation of Ultra2 and Ultra devices at the full burst rate of each bus Extended cable lengths of up to 12 meters for Ultra2 devices All four connectors on card can be used concurrently Connect up to 15 SCSI peripherals Tested for compatibility with over 350 systems and peripherals Key Benefits Maximum Performance The SCSI Card 2940U2W can burst data up to 80 MByte/sec on the Ultra2 SCSI bus, which doubles the maximum burst rate of Wide Ultra SCSI. This Ultra2 SCSI transfer rate translates into increased performance of data intensive applications. Assured Ultra2 Performance With SpeedFlex Technology The SCSI Card 2940U2W features SpeedFlex technology which ensures the most performance from Ultra2 peripherals by creating two electronically isolated SCSI bus segments on the card--an Ultra2 segment and an Ultra SCSI segment. These two segments enable the SCSI Card 2940U2W to simultaneously operate at both Ultra2 SCSI and Ultra SCSI speeds. With SpeedFlex, the board can support Ultra2 peripherals at speeds up to 80 MByte/sec on the Ultra2 SCSI bus segment, while simultaneously supporting Fast and Ultra SCSI devices at speeds up to 40 MByte/sec on the Ultra SCSI s s s s s 8080 MByte/sec MByte/sec Wide Ultra2 SCSI Wide Ultra2SCSI 60 60 40 40 40 40 MByte/sec MByte/sec Wide Ultra SCSI Wide Ultra SCSI 2020 MByte/sec MByte/sec Ultra SCSI Ultra SCSI 20 20 Maximum SCSI Rate Rate Maximum SCSI Burst Burst Adaptec, Inc. 691 South Milpitas Boulevard Milpitas, California 95035 Tel: (408) 945-8600 Fax: (408) 262-2533 Adaptec Europe - Belgium Tel: (32) 2-352-34-11 Fax: (32) 2-352-34-00 Adaptec Japan - Tokyo Tel: (81) 3-5365-6700 Fax: (81) 3-5365-6950 Adaptec Singapore Tel: (65) 278-7300 Fax: (65) 273-0163 Literature: 1-800-934-2766 (USA and Canada) or (510) 732-3829 Pre-Sales Support: 1-800-442-7274 (USA and Canada) or (408) 957-7274 World Wide Web: http://www.adaptec.com Internet ftp server: ftp.adaptec.com CompuServe: GO ADAPTEC Microsoft Network: GO ADAPTEC Adaptec USA Bulletin Board Service (BBS): (408) 945-7727 (up to 28,800 baud, using 8 bits, 1 stop bit, no parity) Interactive Fax: (303) 684-3400 SCSI CARD 2940U2W Complete Kit Contents: · AHA®-2940U2W PCI-to-Ultra2 SCSI card · Adaptec Family Manager Set software drivers for Windows NTTM 4.0 & 5.0, Windows® 95, NetWare 3.1X & 4.X, SCO UnixWare 2.1.2, OS/2 Warp 3 & 4, and SCO Unix 3.2v4.2 · Adaptec EZ-SCSITM: Installation software plus a suite of 32-bit peripheral management applications · 68-pin Ultra2 SCSI internal cable with termination · 68-pin Wide Ultra SCSI internal cable · 50-pin Ultra SCSI internal cable · 50-pin internal-to-external Ultra SCSI cable with external bracket · Complete user documentation · Five-year warranty card Technical Specifications Computer Bus: Interface Protocol: Host Bus Burst Data Rate: Maximum Data Transfer Rate: Peripheral Bus: SCSI Synchronous Maximum Burst Rates: 32-bit PCI local bus Bus master DMA 133 MByte/sec 80 MByte/sec 8-bit & 16-bit Ultra SCSI, 16-bit Ultra2 SCSI Ultra2 SCSI-up to 80 MByte/sec in 16-bit mode Ultra SCSI-up to 40 MByte/sec in 16-bit mode and 20 MByte/sec in 8-bit mode SCSI-1, SCSI-2, SCSI-3, Ultra SCSI, Ultra2 SCSI - Multithreaded I/O (up to 255 tasks simultaneously) - Scatter/gather - Disconnect/reconnect - Tagged command queuing - 68-pin High-Density Ultra2 SCSI - 68-pin High-Density Ultra2 - 68-pin High-Density Wide Ultra SCSI - 50-pin High-Density Ultra SCSI Up to 15 SCSI peripherals (internal or external) 68-pin Wide Ultra SCSI Connector 68-pin Wide Ultra2 SCSI Connector 50-pin Ultra SCSI Connector Ultra SCSI Segment Ultra2 SCSI Segment AIC-7890A AIC-3860 Device Protocol: Advanced SCSI Features: External Connector: Internal Connectors: Device Support: Copyright 1997 Adaptec, Inc.
