Definition of DB-68

DB-68, also known as SCSI-5 or VHDCI (Very High-Density Cable Interconnect), is a type of connector used in computer technology for data transfer. It consists of a 68-pin connector with a compact, high-density design, typically found on SCSI devices such as hard drives and tape drives. This type of connector allows for smaller devices and more efficient use of space while maintaining the same data transfer capabilities as larger connectors.

Key Takeaways

  1. DB-68 is a versatile connector commonly used in data and communication applications.
  2. It features a high-density 68-pin interface, providing a compact and reliable connection solution.
  3. Compatible with various devices like SCSI hard drives, servers, data storage systems, and telecommunications equipment.

Importance of DB-68

The technology term DB-68, also known as a SCSI-5 connector, is important because it represents a crucial component in Small Computer System Interface (SCSI) devices prevalent in data storage and transfer.

As a high-density, 68-pin connector, DB-68 plays a vital role in connecting SCSI hardware such as hard drives, CD-ROM drives, and scanners to computers.

By enabling higher data transfer rates, faster communication, and efficient synchronization between computer systems and peripherals, DB-68 has significantly contributed to enhancing the performance of computing technology over the years.

Although it may be less common in modern computer systems, the DB-68 connector remains an important milestone in the advancement of data storage and communication solutions.


DB-68, also known as HD-68 or SCSI-68, is a type of 68-pin connector used in high-speed data and interface connections. SCSI-68 connectors were commonly employed in Small Computer System Interface (SCSI) devices, which allowed for multiple peripheral devices to be connected and managed efficiently by computers.

The primary purpose of DB-68 connectors was to enhance performance in data transfer of storage devices, such as hard drives, scanners, CD-ROMs, and tape drives. As a vital component in data transmission, DB-68 connectors played an essential role in vast arrays of devices and systems, from personal computers to servers and data centers.

The establishment of physically stable and precise connections was crucial to ensure seamless integration, optimal performance, and reliability. The emergence of newer technologies, such as SATA and SAS, led to SCSI-68 connectors being relegated to legacy systems.

Despite this, the DB-68 connector and SCSI interfaces were critical in advancing computer systems and fostering the progress observed in today’s data and interface connections.

Examples of DB-68

The DB-68 connector, also known as the SCSI-5 or VHDCI (Very High-Density Cable Interconnect) connector, is a high-speed, high-density, multi-channel cable connector typically used in server, industrial, and communication applications. Though it’s not a technology in itself, it is a crucial part of various technologies that utilize it. Here are three real-world examples:

Data Storage Systems: The DB-68 connector is used in data storage systems (such as RAID arrays or servers) to support the transmission of high-volume data. It is often utilized in connecting SCSI devices like hard drives, tape drives, and disk arrays due to its high-density and low profile design.

Networking Equipment: The DB-68 connector is widely used in networking applications, allowing communication between high-performance computers, switches, routers, and other devices that require reliable and speedy data transmission. It can be found on various types of server hardware and network interface cards.

Industrial Controllers and Automation: The DB-68 connector can be seen on industrial controllers and automation systems that require high-speed data transfers. It can be used, for example, in programmable logic controllers (PLCs) that control industrial machines and processes, ensuring that multiple devices can efficiently communicate with each other in an industrial environment.

FAQ – DB-68

What is the DB-68 connector?

The DB-68, also known as HD68 or half-pitch D-type 68-pin connector, is a high-density connector typically used for SCSI-3 applications such as connecting SCSI devices like hard drives, tape drives, and CD-ROM drives to a computer or server.

What is the difference between DB-68 and other SCSI connectors?

The main difference between DB-68 and other SCSI connectors like DB-25 or DB-50 is the density of the pins and size of the connector. DB-68 has 68 closely spaced pins, whereas DB-25 has 25 pins and DB-50 has 50 pins. Additionally, the DB-68 is more commonly used in SCSI-3 and Ultra SCSI standards, while DB-25 and DB-50 connectors are found in older SCSI versions.

What cables and devices are compatible with the DB-68 connector?

DB-68 connectors are used with SCSI-3 and Ultra SCSI cables, devices, and adapters. Some examples of compatible devices include hard drives, tape drives, and CD-ROM drives. Ensure that the end of the cable or adapter matches the connection type on the device, e.g. passive or active terminators, VHDCI, etc., when connecting a DB-68 compatible device.

Can I use a DB-68 connector with older SCSI standards?

It is possible to use a DB-68 connector with older SCSI standards, provided that you have the correct adapter or cable to convert the connections. However, keep in mind that compatibility issues may arise, and you may not get the same transfer rates as when using a connector specifically designed for that SCSI standard.

How can I identify a DB-68 connector?

A DB-68 connector can be identified by its rectangular shape, 68-pin configuration, and dense spacing between the pins. The rows of pins are parallel, and the connector is often labeled “P68” or “HD68” for identification. Look for these markings and the number of pins to ensure you have a DB-68 connector.
