We turn the topic to the hard disk interface. As a special interface for small computer systems, SCSI, like SATA and other storage interfaces, has ushered in its golden development period with the widespread popularity of computers and other equipment. In this renewal plan, we will start with the basic introduction of SCSI, and describe its current application situation in sections.
What is a SCSI connector
It is an interface that connects the host and peripheral devices, and supports a variety of devices including hard disks, optical drives, and scanners. The SCSI bus is a parallel bus commonly used in enterprise storage.
Advantage
Wide adaptability, high performance, large cache capacity, and low CPU usage.
Disadvantage
The installation is complicated, and the subsequent device connection requires certain skills.
Specific use of SCSl connector
1. A host adapter and eight SCSI peripheral controllers can be connected to the SCSI bus. The peripherals can include magnetic disks, magnetic tapes, CD-ROMs, rewritable CD-ROM drives, printers, scanners, and communication equipment.
2. It is also a multi-task interface with bus arbitration function. Multiple peripherals attached to a SCSI bus can work simultaneously. Devices on SCSI occupy the bus equally.
Types of SCSI Connectors
SCSI connectors are divided into two types: built-in and external. The appearance of the built-in data cable is the same as the IDE data cable, but the number of pins and specifications are slightly different. It is mainly used to connect optical drives and hard disks. The 40-pin IDE cable has 40 wires, the 40-pin ATA66 has 80 wires, and the SCSI built-in is divided into 50-pin, 68-pin and 80-pin.
2 Important Terms for SCSI Connectors
Single Ended
Many legacy devices are single-terminated devices that limit
The length of 6 meters is based on the SCS1-1 protocol. Note: this
Distance includes the distance of cables inside the device.
Differential
The SCSI bus and devices use it to

The maximum length of the additional line is 25 meters. shortcoming
is not compatible with single-terminated devices.
