What are SCSI connectors?

      The Small Computer Systems Interface, or SCSI connector, (pronounced “scuzzy”) is a veteran of the small computing world. In the 1980s, this fast I/O connector served as a bus to link computers with components or peripherals such as disk drives. SCSI connectors typically feature two rows of pins in a robust, roughly D-shaped housing, although some variations organized the pins in shorter multiple rows. Early Macintosh personal computers utilized the SCSI for nearly every connection. While the rise of the USB and card edge connectors has led to the SCSI largely falling out of use in computing applications, current iterations are still used in some network applications.

        The SCSI bus is controlled by a host controller, typically in the motherboard, or from a separate expansion card. SCSI uses three different signaling types: single-ended (SE), high-voltage differential (HVD), and low-voltage differential (LVD). Many versions of the SCSI connector have been used over the past three decades, most of which have become obsolete as smaller interfaces have evolved. Parallel SCSI connectors handle an 8, 16, or 32 bit wide bus running at 5, 10, or 20 megatransfers, with conventional or differential signaling. Today, these versions of SCSI have largely been replaced by Serial Attached SCSI (SAS), which includes three more transport types, each with one or more connector types. 24G SAS technology is widely integrated in modern data centers and storage applications.

What is SCSI connector used for?

       SCSI, or Small Computer Systems Interface, is technology designed to connect smaller devices to a computer. SCSI is bus technology, which means that all devices connect to a central bus and are "daisy-chained" together.
