Two short Mini SAS HD SFF-8643 cables, matte black connectors, .5m length

BUCIER

BUCIER Mini SAS HD SFF-8643 cable with sideband 12G 100-Ohm .5m 2 pack

SKU CH-KXBP-0TBWE

Connects two Mini SAS HD SFF-8643 ports with sideband at 12 Gbps over 0.5 m, 100-Ohm impedance, two cables

Cable Length 1.64 Feet

  • 12 Gbps bandwidth supports high-throughput storage arrays
  • 100-Ohm impedance preserves signal integrity over the link
  • Sideband wiring enables enclosure management and monitoring
  • 5 m length keeps internal routing tidy
  • Two-cable pack provides a spare or dual-controller setup

Internal SAS HD SFF-8643 cable pair

This two-pack provides 0.5-metre internal cables with SFF-8643 connectors on both ends. Each cable carries a sideband channel and is rated for 100-Ohm impedance. They support data rates up to 12Gbps for SAS interconnects. The 1.64-foot length suits compact chassis routing.

Storage builders needing short 12Gbps links

The cables suit servers or workstations linking backplanes, RAID controllers or HBAs with SFF-8643 ports. Builders who need longer runs, external connectors or a different pin-out should look at other cable types. The fixed 0.5-metre length limits placement flexibility in larger enclosures.

12Gbps rating with sideband on SFF-8643

The single specification that decides fit is the 12Gbps data-rate support combined with sideband signalling on the SFF-8643 interface. Verify the host controller and backplane both operate at this speed and require the sideband channel. Mismatched signalling or speed expectations will prevent the link from training.

Questions about this item

What controller or backplane connectors does the SFF-8643 end plug into?

The SFF-8643 connectors mate with Mini SAS HD ports found on 12 Gb/s SAS HBAs, RAID controllers or backplanes.

Will the 100-Ohm impedance and sideband wiring work with a 6 Gb/s SAS expander I already own?

Yes, the 12 Gb/s-rated cable is backward compatible and the sideband pins carry SGPIO or I²C signals the expander expects.

How can I verify the link is running at 12 Gb/s after installation?

Check the controller BIOS or OS utility — it should report a 12 Gb/s negotiated speed on each port with zero CRC errors.
