What are VHDCI connectors, and where are they commonly used?
VHDCI (Very High-Density Cable Interconnect) connectors are high-density connectors utilized for transmitting data signals, especially in server and storage environments. They typically feature 68 or 80 pins arranged in a compact form factor, enabling multiple data channels within a confined space.
What are typical cable runs for VHDCI connections?
Cable runs for VHDCI connections vary based on setup requirements and cable quality. Generally, VHDCI cables are suited for short runs, typically ranging from a few feet to around 15 feet (1 to 5 meters). These lengths are ideal for connecting devices within the same server rack or equipment enclosure.
What happens with longer cable runs for VHDCI connections?
Longer cable runs may result in signal degradation, leading to reduced data transmission speeds or errors in data transfer. It’s recommended to adhere to recommended cable run limits to maintain optimal performance and reliability.
What types of applications commonly use VHDCI connectors?
VHDCI connectors are primarily employed for data transmission rather than video signals. They are commonly utilized in applications such as SCSI (Small Computer System Interface) connections for storage devices, as well as in high-speed data transfer applications like InfiniBand and PCIe (Peripheral Component Interconnect Express) connections.
How can signal integrity be maintained for longer VHDCI cable runs?
For longer cable runs, signal repeaters, active cables, or fiber optic cables may be necessary to maintain signal integrity and ensure reliable data transmission over extended distances. Using high-quality cables and connectors designed for VHDCI connections can also minimise signal degradation and ensure optimal performance in demanding server and storage environments.
