  Adaptec 2940UW PCI SCSI, Bulk
  

  High-performance Ultra Wide SCSI for workstations and entry-level servers

  Product Highlights

   

  • 40 MByte/sec Ultra Wide SCSI data transfer rate
  • Connection for up to 15 SCSI peripheral devices
  • Designed for true multitasking
  • Tested for compatibility with hundreds of systems and peripherals from major manufacturers
  • Most popular SCSI host adapter family in the industry

  The AHA-2940 Ultra Wide host adapter is the ideal PCI-to-SCSI host adapter for entry-level servers and workstations. It moves data fast -- up to 40 MByte/sec. And it connects up to 15 SCSI devices for expanded storage capacity. In addition, the AHA-2940 Ultra Wide adapter delivers unrivaled system and peripheral compatibility.

  Key Benefits

  Fastest data transfer speed

  Combining UltraSCSI speed and 16-bit wide SCSI data transfers, the AHA-2940 Ultra Wide host adapter moves data on the SCSI bus at a maximum rate of 40 MByte/sec. By increasing the throughput rate between peripherals and the system CPU, the AHA-2940 Ultra Wide adapter accelerates system performance and user productivity.

  Most peripheral connections

  The AHA-2940 Ultra Wide host adapter delivers expanded connectivity to meet the storage capacity requirements of server environments. It supports up to 15 SCSI devices simultaneously. Both 8-bit and 16-bit devices can be configured in any combination for maximum configuration flexibility.

  Time-saving multitasking

  The AHA-2940 Ultra Wide host adapter makes true multitasking possible. SCSI technology offers unique features, including disconnect/reconnect, tagged command queuing, and multithreaded I/O, that allow the system CPU to move data to and from multiple peripheral devices simultaneously.

  Unparalleled compatibility

  All Adaptec host adapters are rigorously tested with hundreds of different SCSI peripherals and systems, which makes them the most compatible and reliable host adapters in the marketplace. The AHA-2940 Ultra Wide adapter is fully compatible with all popular desktop and network operating systems, including Microsoft® Windows® 3.1, DOS, Windows NT™, Windows® 95, OS/2, NetWare, and UNIX. Under Windows 95, the AHA-2940 Ultra Wide adapter utilizes advanced Plug-and-Play features that automatically assign IDs and control termination.
