The Small Computer System Interface (SCSI) is a common set of standards.

The

www.scsita.org website states, "SCSI stands for Small Computer System Interface ─ a set of

standards for physically connecting and transferring data between computers and peripheral

devices such as hard disk drives and solid-state disk drives. The SCSI-3 standard, also known as

SCSI-3 Architecture Model (SAM), is a set of specifications that illustrates the architecture of

SCSI-3 devices and systems. The website www.techopedia.com states, "The SCSI-3 standard is

a collection of other standards. These standards are arranged into a framework based on the

SCSI-3 architecture documents."

SCSI-3 was designed by the SCSI Trade Association (STA), an industry group that

includes manufacturers, distributors, and other organizations involved in developing and using

SCSI technology. One of the main goals of SCSI-3 is to provide flexibility and interoperability

between SCSI-3 devices and systems. This is accomplished through a layered architecture that

splits the SCSI-3 protocol into several layers, each responsible for a specific aspect of SCSI-3

communication.

One of the key features of SCSI-3 is its support for multiple transfer modes, including

asynchronous, synchronous, Fast-20, Fast-40, and Ultra-320. These different transfer modes

allow SCSI-3 devices to transfer data at different speeds, depending on the device's capabilities

and the application's requirements. Another essential feature of SCSI-3 is its support for multiple

device types, including initiator devices, which initiate SCSI-3 commands and data transfers, and

target devices, which respond to SCSI-3 commands and data transfers.

Overall, the SCSI-3 standard is an essential set of specifications that defines the

architecture of SCSI-3 devices and systems. By providing a high degree of flexibility and
interoperability, SCSI-3 allows for the seamless integration of a wide range of SCSI-3 devices

and systems, making it an essential technology for modern computer systems.
