unsurpassed system and peripheral compatibility.
KEY BENEFITS
Double the data transfer speed
Using UltraSCSI technology, the AHA-2940 Ultra host adapter doubles the maximum data
transfer rate on the SCSI bus from 10 MByte/sec to 20 MByte/sec. By increasing the
throughput rate between peripherals and the desktop system, the AHA-2940 Ultra adapter
accelerates system performance and user productivity.
Improved system performance
In addition to UltraSCSI speed, the AHA-2940 Ultra host adapter features a
high-performance bus mastering architecture that regulates data movement directly between
peripherals and system memory. The onboard Adaptec PhaseEngine® RISC processor takes over
I/O processing from the CPU, which frees it for other tasks. The result is lower CPU
utilization and noticeably faster response time.
Time-saving multitasking
AHA-2940 Ultra 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 access data on 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 adapter is also fully compatible with all popular
desktop and network operating systems, including DOS, Windows®, Windows NT™,
Windows® 95, OS/2, NetWare, and UNIX.
Easy installation
Installing the AHA-2940 Ultra host adapter is quick and easy. Simply insert the host
adapter in the PCI slot and the system BIOS will assign resources to it. Using the SCSISelect®
utility, users can then fine tune the performance of the adapter by making on-screen
choices from the utility menu.
Under DOS, Windows, and Windows 95 environments, Adaptec EZ-SCSI&$174; software
automatically determines what hardware is present, loads the correct drivers, and modifies
system configuration files. Completely compatible with Windows 95, the AHA-2940 Ultra host
adapter utilizes advanced Plug-and-Play features that automatically assign IDs and control
termination.
