  • 1 m length suits typical server chassis

BUCIER 12G Mini SAS HD Cable

This BUCIER cable pair connects internal Mini SAS HD SFF-8643 ports at up to 12Gbps. It suits server and workstation builders who need direct drive-to-controller or backplane links. Each cable includes sideband conductors and a 100-Ohm impedance match. The two-pack provides a spare or a second channel.

1 m length with sideband support

At 1 m (3.3 ft) the cable reaches across typical chassis depths without excess slack. Sideband wiring carries SGPIO or I²C signals for enclosure management and drive-status LEDs. The 100-Ohm differential impedance maintains signal integrity on 12 Gbps SAS lanes. No additional adapters are required for SFF-8643 ports.

Sustained 12Gbps throughput

The 100-Ohm controlled impedance preserves eye-diagram margins during continuous heavy I/O workloads. Sideband lines remain active for enclosure firmware monitoring throughout long transfers. Builders needing longer runs or external bulkhead connections should look elsewhere. The fixed 1 m length limits routing flexibility in oversized enclosures.
