Adaptec(reg) MultiChannel(tm) SCSI host adapters A Modern, Multi-lane Highway for High-speed Data Traffic --------------------------------------------------------------------------- Today, data traffic needs multiple lanes With Adaptec MultiChannel SCSI host adapters, you're no longer limited to a single I/O lane that can impede progress and productivity. Adaptec MultiChannel SCSI host adapters let you turn a single I/O slot into a high-capacity traffic artery that keeps things moving among throughput-generating peripherals and applications. Configuring competitive servers If you're a systems integrator or a value-added reseller, you have to compete with increasingly capable servers from big-name workstation and server vendors. And it's not just price competition. You have to keep up in performance with servers that have multichannel SCSI chips built into the motherboards. If the I/O port of the servers you configure is a bottleneck that slows down data traffic, you could get left behind. That's why you need Adaptec MultiChannel SCSI host adapters. To increase the number of devices that can be connected to the server. To speed the flow of data. To increase the virtual number of available I/O slots. And to satisfy end users so that your customers keep coming back. Whether you configure Pentium-based servers or servers running the Macintosh operating system, Adaptec MultiChannel SCSI host adapters can put you back in the fast lane. Multichannel SCSI to keep data moving How do you eliminate I/O gridlock? With two channels powered by two independent RISC processors and connected by a PCI-to-PCI bridge in a single PCI slot. Adaptec offers a full line of MultiChannel PCI-to-SCSI host adapters based on the proven technology of our popular AHA(reg)-2940 PCI host adapter line. The 8-bit AHA-3940 and the 16-bit AHA-3940W adapters for the Intel-based systems, support up to 30 devices, and transfer data up to 40 MByte/sec. The PowerDomain(tm) 3940UW accelerator for Power Macintosh(tm) systems supports 30 devices and transfer data at 80 Mbyte/sec. The complete kit includes installation software for all major operating systems, easy-to-use tools and applications for managing peripherals, internal cables, device support, and manuals. [Speed comparisons] As more devices are added, the multichannel adapter allows the additional drives to be fully utilized. Accelerating performance More devices and more kinds of devices The AHA-3940 host adapter accommodates up to 14 high-performance disk drives, CD-ROM drives, tape drives, CDRs, and other devices. The AHA-3940W can handle 30 devices. Faster throughput With multiple channels, faster peripherals can have their own lane, where throughput won't be impeded by slower devices. Data integrity If data integrity is most important, the multiple channels can be used for data mirroring to protect crucial information. Significant savings Adaptec MultiChannel adapters free up slots to accommodate expansion by doubling the number of devices that a single PCI slot can accommodate. Since one card does the work of two, the cost per channel of growing a system is reduced. Efficient peripheral management Adaptec EZ-SCSI(reg) installation software takes the work out of installing the host adapter. Adaptec's unique SCSISelect(reg) optimization utility makes it easy to add or remove SCSI peripherals and fine-tune performance. And Adaptec CI/O(tm) management software lets your customers efficiently manage the performance of their SCSI devices across the network. A wide range of OS support With Adaptec's enabling software, the Adaptec MultiChannel product line supports all of the major operating systems, including DOS, Windows(reg), NetWare, Windows NT(tm), OS/2, SCO UNIX, UnixWare, Banyan Vine, Macintosh OS, AIX, and Solaris. Keeping up with applications More complex tasks. New media. Faster throughput. These are the demands leading-edge applications make on the servers you supply. Adaptec MultiChannel products can help you meet them. On-line transaction processing and database management Record-keeping, database queries, and decision support are increasing as organizations face the need to be more efficient. Adaptec MultiChannel adapters give your customers the short search times, data integrity, and economic expansion needed for heavy database traffic. Web servers Organizations are using Web server software and browsers to reengineer processes. Servers that host workgroup functions often act as internal Web servers too. Multiple channels in the server's I/O port prevent data traffic jams. Digital video editing and software title authoring As new media come on line, smooth-motion video, layering, audio-track mixing, subpixel positioning, and morphing demand fast search, preview, and render times. And speed means productivity. Adaptec MultiChannel adapters can handle the increasing number of devices that connect to the server and keep the data moving quickly among them. --------------------------------------------------------------------------- Adaptec, Inc. 691 South Milpitas Boulevard Milpitas, California 95035 Adaptec Europe Belgium Tel: (32) 2-352-34-11 FAX: (32) 2-352-34-00 Adaptec Japan Tokyo Tel: (81-3)-5276-9882 FAX: (81-3)-5276-9884 Adaptec Singapore Tel: (65) 278-7300 FAX: (65) 273-0163 --------------------------------------------------------------------------- Literature: 1-800-934-2766 (USA and Canada) (510) 732-3829 Ordering Software: 1-800-442-7274 (USA and Canada) (408) 957-7274 Interactive FAX : (408) 957-7150 Adaptec USA Bulletin Board: (408) 945-7727 (up to 28,800 baud, using 8 bits, 1 stop bit, no parity) CompuServe: GO ADAPTEC Microsoft Network: GO ADAPTEC Internet ftp server: ftp.adaptec.com World-Wide Web: http://www.adaptec.com/ --------------------------------------------------------------------------- Copyright 1996 Adaptec, Inc.
