Cable Leader SCSI-3 LVD HPDB68 M/M Cable
The Cable Leader SCSI-3 LVD HPDB68 M/M Cable is designed for high-density SCSI setups requiring reliable LVD/SE performance. With 30 AWG conductors arranged as 34 twisted pairs and shielding consisting of aluminum foil and copper braid, this cable emphasizes signal integrity and EMI resistance. The thumbscrew connectors help secure the connection in server and workstation racks, reducing the risk of accidental disconnects during busy data transfers. At six feet, the length offers flexibility for mid-range server rooms or PC-based storage arrays. This option suits users upgrading legacy systems or expanding a small to mid-size storage stack where 320 Mbps LVD/SE is sufficient for transfer workloads.
SCSI-3 Cable, 3 Ft HPDB68 Male to Male
This 3-foot SCSI-3 cable, featuring HPDB68 Male-to-Male connectors, is tailored for compact SCSI-III environments. It supports LVD/SE up to 320 Mbps, making it a practical choice for short-distance connections between older discs, scanners, or drives and SCSI controllers. The compact length helps reduce cable clutter in dense server rooms or workstations with multiple peripheral connections. The HPDB68 connectors provide a secure fit, while the 34 twisted pairs enable robust data integrity across standard SCSI devices. Use it when you need a reliable, short-range link without excessive slack.
CableWholesale SCSI III LVD Cable
The CableWholesale SCSI III LVD Cable comes in a black, durable exterior with 34 twisted pairs and gold-plated connectors. The gold plating improves corrosion resistance and conductivity, contributing to steadier data transfers and lower signal degradation over time. The 3-foot length is ideal for short, tidy connections between devices that sit close to the controller or enclosure. Its high-quality construction supports consistent performance in professional IT deployments or home labs, where reliability and EMI/RFI resistance are crucial for uninterrupted data flow.
6ft Ext SCSI Cable Se/hvd/lvd Vhdci-hd68
The HP 6-foot ext SCSI cable covers a broad range of SCSI connections, including VHDCI and HD-68 interfaces. This flexibility is advantageous in environments with mixed device types or older equipment that uses varied connector standards. The longer length supports extended distances within racks while maintaining signal integrity through careful shielding and robust conductor design. This option fits data center maintenance, vintage workstation restoration, or mixed-media workstations requiring dependable LVD/SE performance across diverse gear.
3ft DB25 Male to CN50 Male SCSI Cable
The CABLESONLINE DB25 to CN50 SCSI cable pairs a DB25 male with a Centronics 50-pin male, designed to withstand EMI/RFI interference through foil and braided shielding. This configuration is common for older SCSI-1 or SCSI-2 devices that still rely on robust shielded data paths. The 3-foot length keeps routing neat in deskside setups or small server cabinets. This option is suitable for those maintaining legacy peripherals or bridging older devices in mixed-technology environments, ensuring reliability without excessive cable slack.
Buying Guide
Key purchase considerations help match cables to systems and budgets. First, identify the connector type on both ends (HPDB68, VHDCI, DB25, CN50, etc.) and confirm the supported SCSI standard (SCSI-III LVD/SE, 320 Mbps). Cable length should balance reach with signal integrity; longer runs may require better shielding and shorter runs reduce crosstalk. Shielding options (foil, copper braid, or both) protect against EMI/RFI in dense racks or industrial environments. Look for robust build features such as thumbscrews and gold-plated connectors for durable, corrosion-resistant connections. For mixed environments, overlays like mixed connector types or universal cables can simplify deployments. Always verify compatibility with your controller and target devices, and consider the environment—home labs versus data-center deployments—when budgeting for higher-quality shielding and connectors.
In practice, prioritize cables that clearly list LVD/SE support and 320 Mbps capability if you operate older SCSI devices. Shorter cables excel in tight spaces, while longer options are useful for intermediate distances between drives and controllers. If your setup includes a mix of SCSI types, opting for cables with wide compatibility (VHDCI to HD-68, DB25 to CN50, etc.) reduces the need for multiple adapters. Shielded, gold-plated connectors deliver reliable performance over time, which is especially valuable in servers and workstations that endure frequent data transfers and reconfigurations.
