Internal SAS HD cable pair for dense server

This two-pack of 10Gtek SFF-8643 cables connects internal Mini SAS HD ports on host bus adapters, RAID controllers or backplanes. Each assembly is 1.64ft long and rated for 12Gbps SAS 3.0 and SAS 2.1 links. The 100-ohm impedance and 30 AWG conductors support Fibre Channel and InfiniBand as well.

Verify connector keying

Both ends use the high-density SFF-8643 interface with sideband signals present. Confirm that your controller and backplane expect the same pinout and that the 0.5-meter reach fits your chassis routing. Cables are RoHS compliant and built to the SAS 3.0 specification.

Short length keeps signal loss

At 1.64ft the cables add minimal insertion loss at 12Gbps and occupy little space in crowded drive bays. The thin 30 AWG jacket bends easily for clean cable management without blocking fan paths. Passive copper construction draws no power and generates no heat or noise.

Questions about this item

Does the 2-pack include any brackets or mounting hardware, or just the two SFF-8643 cables?

The pack contains two internal Mini SAS HD SFF-8643 cables, each 1.64ft long with sideband support. No brackets, screws or additional hardware are included.

When should I choose the 1.64ft length over a longer cable for a 12Gbps SAS link?

Choose the 0.5-metre length when the backplane and controller are close together. Shorter runs reduce signal loss and improve integrity at 12Gbps.

What does the 12Gbps rating mean when the cable is installed in a SAS 2.1 chassis?

The cable supports up to 12Gbps per lane. In a SAS 2.1 chassis it will operate at 6Gbps, but the 100-Ohm impedance and 30AWG construction maintain signal quality for future upgrades.
