The Ultimate Guide to SCSI Cables: Types, Connectors, and Applications
Introduction
SCSI (Small Computer System Interface) cables are essential components in the world of data storage and peripheral connectivity. These specialized cables enable high-speed communication between computers and a wide range of devices, including hard drives, scanners, printers, and more. With their ability to support multiple devices in a daisy-chain configuration, SCSI cables offer a versatile and efficient solution for various computing environments.
Understanding SCSI Cables
SCSI cables come in different varieties, each designed to cater to specific needs and compatibility requirements. The most common types include:
- VHDCI (Very High-Density Cable Interconnect) Cables: These cables feature a 0.8mm 68-pin male connector on one end and are commonly used to connect SCSI storage devices and peripherals.
- HPDB (High-Performance Parallel Bus) Cables: With a 68-pin or 50-pin male connector, HPDB cables are widely used in SCSI-2 and SCSI-3 setups, offering reliable connectivity for various devices.
- Centronics Cables: Also known as CN50 cables, these feature a 50-pin male connector and are often used to connect older SCSI-1 peripherals to newer SCSI-2 host controllers.
SCSI Cable Connectors
SCSI cables employ different connector types to ensure compatibility with various devices and standards. The most common connectors include:
- VHDCI 0.8mm 68-Pin Male: This connector is commonly found on VHDCI cables and is used for connecting SCSI storage devices and peripherals.
- HPDB 68-Pin Male: This connector is widely used in SCSI-3 setups and is often found on HPDB cables.
- HPDB 50-Pin Male: This connector is commonly used in SCSI-2 setups and is found on HPDB cables.
- Centronics 50-Pin Male: This connector is used on Centronics cables and is often employed for connecting older SCSI-1 peripherals to newer SCSI-2 host controllers.
SCSI Cable Specifications
SCSI cables are designed to meet specific performance and durability requirements. Here are some key specifications to consider:
- Conductor: Most SCSI cables feature twisted-pair conductors, typically 34 twisted pairs of 30 AWG or 28 AWG wire, to ensure reliable data transmission and minimize interference.
- Cable Color: SCSI cables are commonly available in black or beige colors, with black being the more prevalent choice.
- Length: SCSI cables come in various lengths, ranging from 3 feet to 6 feet or more, to accommodate different setups and distance requirements.
Applications and Usage
SCSI cables are widely used in a variety of applications, including:
- Storage Connectivity: SCSI cables are essential for connecting SCSI storage devices, such as hard drives, tape drives, and CD/DVD drives, to computers or servers.
- Peripheral Connectivity: SCSI cables enable the connection of various peripherals, including scanners, printers, and other external devices, to computers or servers.
- Enterprise and High-Performance Computing: SCSI cables are commonly found in enterprise-level servers, storage arrays, and high-end workstations, where reliable and high-speed data transfer is crucial.

SCSI Cable FAQs
What is a SCSI cable used for?
SCSI (Small Computer System Interface) cables are used to connect computers with a broad range of devices, including hard drives, CD-ROMs, printers, and scanners. They provide a high-speed bus connection between the computer and peripherals, facilitating efficient data transfer. For more information on our SCSI cables, please visit our website.
What are the two basic types of cabling for SCSI?
SCSI-1 has an 8-bit port that uses a 50-pin connector and single-ended, open-collector drives. SCSI-2 offers faster data transfer rates, better connectors, a wider bus path, parity checking, and improved reliability via synchronous negotiation. Our HPDB50 Male to Male and VHDCI 68 Male to Male cables support these standards.
What are the different types of SCSI?
Different SCSI standards use the same connectors, such as HVD (High-Voltage Differential) and LVD (Low-Voltage Differential). HVD uses 15V, while LVD uses 3.3V. Connecting an HVD device to an LVD host bus adapter or vice versa can cause damage. Our SCSI cables are designed to be compatible with various SCSI standards and voltage levels.
What does a SCSI connection look like?
SCSI connectors typically feature two rows of pins in a robust, roughly D-shaped housing, although some variations organize the pins in shorter multiple rows. The VHDCI 68 to HPDB68 and HPDB50 Male to Male cables from CableLeader exemplify these connector types.
