Adaptec HD-SAS Cable Internal SFF-8643 4xSAS 0.8m

Adaptec HD-SAS Cable – Internal SAS Data Cable with Sideband and Power

The Adaptec HD-SAS cable connects a SAS controller to hard drives or backplanes via SFF-8643 to SFF-8482. It is designed for installation in servers and storage systems and supports Sideband signals for chassis management.

• Reduces cable clutter inside the chassis by combining 4 SAS ports in one cable – ideal for space-saving internal builds
• Sideband communication enables monitoring of drive status and chassis fans without additional control wires
• Integrated Molex power supply directly powers connected devices
• Angled connector on one side eases routing in tight enclosures
• 80 cm cable length offers flexibility when wiring between controller and drive bay

What sets this Adaptec HD-SAS cable apart

Unlike standard SAS cables, this model combines Sideband, power delivery, and a compact design in one cable. The SFF-8643 interface on the controller side is compatible with common SAS controllers, while SFF-8482 connects directly to SAS drives or backplanes. The 90-degree angle at one end simplifies installation even in confined spaces.

Ideal for system integrators and server administrators

This cable is the first choice for building or expanding SAS-based storage solutions, whether in workstations, NAS systems, or data centers. It saves time during cabling and improves airflow inside the chassis due to bundled cables.

How to use the Adaptec HD-SAS cable

1. Connect the SFF-8643 connector (Side A) to the controller
2. Connect the four SFF-8482 outputs to the SAS drives or a backplane
3. Ensure the Molex power connection (if required)
4. Route the cable so that the angled side faces the desired direction
