Product Description
The Adaptec AHA-2940-S6 is a PCI host adapter designed to bring Ultra SCSI connectivity to desktop computers and servers. It utilizes a 32-bit PCI bus, allowing it to be installed in most standard PCI slots available on motherboards from the era. This controller card enables users to connect a variety of SCSI devices, such as hard drives, tape drives, and scanners, to their system. Featuring one 68-pin external connector (often referred to as HD68), the AHA-2940-S6 is specifically designed for connecting external SCSI peripherals. The Ultra SCSI standard supported by this card offers a maximum theoretical data transfer rate of 20 MB/s, providing significantly faster performance than earlier SCSI standards or IDE interfaces of its time. It also supports Bus Master DMA, which allows the controller to transfer data directly to and from system memory without involving the CPU, thereby improving overall system performance. This controller card is a valuable component for systems requiring reliable and high-speed access to storage devices, particularly in server environments where multiple drives or high-capacity storage solutions are common. Installation typically involves inserting the card into a PCI slot and installing the appropriate drivers for the operating system. The Adaptec AHA-2940-S6 provides a robust solution for adding or expanding SCSI capabilities.
