Length 6.56 ft.

Style SFF-8644 to SFF-8644

  • Supports 12Gbps per channel for high-speed SAS links
  • SFF-8644 connectors on both ends ensure direct compatibility
  • AWG30 twinaxial wire with 100 Ohms impedance maintains signal integrity
  • Compliant with SAS 2.1 and 3.0 specifications for broad system support
  • 2-metre length gives flexible rack-to-rack or enclosure placement

12Gbps External Mini SAS HD Cable

This 10Gtek cable connects two SFF-8644 Mini SAS HD ports for external SAS 2.1 and SAS 3.0 links. It uses AWG30 twinaxial 8-pair wire with 100 Ohm impedance to deliver up to 12Gbps per channel. The 6.56 ft length suits rack-to-rack or enclosure-to-server runs. EEPROM signature allows host identification of cable type and length.

Suits SAS storage arrays and HBA links

Builders linking external JBODs, RAID enclosures or HBAs with SFF-8644 ports will use this passive copper assembly. The improved latch reduces insertion force while increasing retention. It is not for internal backplane routing, for single-lane connections, or for any interface other than SAS. Buyers needing longer reaches or active optical cables should look elsewhere.

12Gbps per channel over 6.56 ft

The single specification that decides fit is the 12Gbps per channel rating across the 6.56 ft AWG30 twinax assembly. This data rate matches SAS 3.0 requirements while the 100 Ohm impedance and low-skew construction protect signal integrity. If your controller or enclosure demands a different connector, length or data rate, this cable will not work.

Questions about this item

Does the 2-metre passive cable generate noticeable heat or draw extra power when running 12 Gbps SAS traffic all day?

The passive twinax assembly has no active components, so it adds no heat or power draw beyond the host ports themselves.

Which host-side connectors must my controller or backplane already provide for this SFF-8644 cable to plug in directly?

Both ends use SFF-8644 4x HD Mini SAS receptacles, so the controller and the target enclosure each need matching SFF-8644 ports.

Will this 12 Gbps-rated cable work reliably with older 6 Gbps SAS expanders or HBAs I still have in the rack?

Yes, the cable meets SAS 2.1 and SAS 3.0 specifications, so it auto-negotiates down to 6 Gbps on legacy gear without signal-quality issues.
