SCSI is most commonly used for hard disk drives and tape drives, but it can connect a wide range of other devices, including scanners and CD drives. SCSI interfaces provide for faster data transfer rates than most other storage technologies. They support Multiple Input/Output devices to be connected simultaneously to a single SCSI interface, allowing for daisy chaining of multiple devices. SCSI is available in several variants, including SCSI-1, SCSI-2, SCSI-3, and SCSI over Fibre Channel and SAS.
Guide on Small Computer System Interface (SCSI)
What is SCSI? Small Computer System Interface (SCSI) is a standard communication protocol that allows computers to communicate with peripheral devices. It was commonly used in servers, mainframes, and supercomputers.
Why is it important? SCSI was a leap forward in technology and laid the groundwork for many of the systems we use today. It was able to move data faster than the existing protocols and could connect several devices together.
How does SCSI work? SCSI works by sending digital signals along a cable to another device. The sending device sets the SCSI ID number, which is then matched with the target device.
