SMUGDESK SFF-8643 to SFF-8087 SAS cable .5m 12Gbps 3.0

SKU CH-A0HV-H1YS1

Connects 12Gbps SAS 3.0 controllers to SFF-8087 backplanes with a .5m shielded cable

  • 12Gbps SAS 3.0 bandwidth for high-speed data transfer
  • SFF-8643 to SFF-8087 connects new RAID cards to legacy backplanes
  • Multi-layer shielding with gold-plated contacts ensures signal integrity
  • 5m braided cable routes easily inside compact server chassis
  • Compatible with LSI, Dell, HP, Supermicro and Lenovo hardware

Connection & Compatibility

This cable provides a direct SFF-8643 to SFF-8087 interface conversion, linking modern Mini SAS HD controllers to legacy SAS backplanes. It suits system integrators and administrators upgrading storage arrays in servers, workstations or NAS units where mixed-generation connectivity is required.

Sustained Signal Integrity

Multi-layer electromagnetic shielding and gold-plated contacts suppress crosstalk and attenuation during continuous high-throughput operation. The braided sleeve protects the cores from abrasion and repeated bending inside dense chassis, maintaining reliable 12Gbps SAS 3.0 transmission over extended duty cycles.

Deciding Specification

The single factor is the SFF-8643 to SFF-8087 pin-out; the cable only works when one endpoint uses the newer Mini SAS HD connector and the other uses the classic Mini SAS connector. Builders needing SFF-8643 on both ends or SFF-8087 on both ends must select a different assembly.

Questions about this item

Does the .5 m braided cable generate noticeable heat or draw extra power during continuous 12 Gbps SAS 3.0 traffic?

The passive copper assembly carries only signal current, so it adds no measurable heat or power draw inside the chassis.

Which controller ports and backplane connectors must my system already provide for this SFF-8643 to SFF-8087 cable to function?

You need a RAID controller or HBA with an SFF-8643 Mini SAS HD port and a drive backplane or expander with an SFF-8087 Mini SAS port.

Will the 12 Gbps SAS 3.0 link negotiate down reliably when plugged into older 6 Gbps or 3 Gbps SAS backplanes?

Yes, the SAS 3.0 interface auto-negotiates to 6 Gbps or 3 Gbps speeds for full backward compatibility with legacy backplanes.
