One-metre black cable with SFF-8644 and SFF-8088 connectors

Vszerda

Vszerda External Mini SAS HD SFF-8644 to SFF-8088 Hybrid Cable 1M/3.3ft 6Gbps

SKU CH-2XWN-XRH9W

Connects SFF-8644 host ports to SFF-8088 storage devices at 6 Gbps over one metre

  • Connects HD Mini-SAS to legacy Mini-SAS gear
  • 6 Gbps per channel for high-speed data transfer
  • 1-metre twinaxial cable with 100-ohm impedance
  • Supports SAS 2.1 and 3.0 specifications
  • Hot-pluggable design for live system maintenance

External Mini SAS HD Cable

This 1-metre hybrid cable links an SFF-8644 Mini SAS HD port to an SFF-8088 Mini SAS connector for external storage links. It is built for server racks, RAID enclosures, direct-attached storage and HBA interfaces that need a straight-through copper connection. The twinaxial eight-pair construction targets 6.0 Gbps per channel across the link.

Practical limits of the 6 Gbps SAS interface

Rated throughput reaches 6.0 Gbps per lane and the design meets SAS 2.1 and 3.0 specifications, so the cable will not exceed those signalling rates. Length is fixed at 1 metre (3.3 ft) and the 100 Ohm impedance with AWG30 conductors sets the electrical budget for the run. Longer distances or higher lane speeds would require a different cable assembly.

Check your existing setup before ordering

Verify that one endpoint presents an SFF-8644 Mini SAS HD receptacle and the other an SFF-8088 Mini SAS receptacle, as the hybrid ends are not interchangeable. Confirm the host controller or backplane supports SAS 2.1 or 3.0 signalling so the 6.0 Gbps rating can be used. Ensure the 1 metre reach fits the rack or enclosure layout without strain on the connectors.

Questions about this item

Should I choose the SFF-8644 or SFF-8088 end for my controller?

The cable has an SFF-8644 connector on one side and an SFF-8088 connector on the other; match the SFF-8644 end to your HD Mini-SAS port and the SFF-8088 end to your legacy Mini-SAS port.

What does the 6 Gbps rating deliver inside a server?

Each of the eight differential pairs carries up to 6 Gbps, giving SAS 2.1 drive performance and full compatibility with both SAS 2.1 and SAS 3.0 interface specifications.

Does the SFF-8644 to SFF-8088 interface limit real-world throughput?

The hybrid cable is certified to the Serial Attached SCSI 6.0 Gbps standard, so the 100 Ohm impedance and 6 Gbps per channel define the practical ceiling for SAS and SATA traffic.
