SFF-8644 to SFF-8088 Mini SAS HD Cable

This 1.5 metre cable connects a Mini SAS HD SFF-8644 port to an external SFF-8088 port using a 26-pin male-to-male design. It is built for servers, RAID controllers and data-centre storage links that require a 6.0 Gbps SAS connection. The 100-Ohm twinaxial construction suits short-range rack-to-rack or rack-to-enclosure cabling. Buyers needing longer runs or fibre-based links should look elsewhere.

Sustained load behaviour

The AWG30 8-pair twinaxial wire is specified for low skew and 100-Ohm impedance to maintain signal integrity at 6.0 Gbps per lane across the full length. The assembly is tested to SAS 2.1 and 3.0 specifications before shipment, so sustained throughput matches the certified lane rate without degradation. No active equalisation or optical conversion is present, so distance remains limited to the supplied 1.5 metres.

Pre-order checklist

Verify that your controller or backplane presents an SFF-8644 Mini SAS HD interface and that the target enclosure or JBOD uses an SFF-8088 external port. Confirm the 1.5 metre reach fits your rack layout including cable management slack. Ensure the 26-pin male connectors match the keying on both devices, as pin-count or keying mismatches will prevent mating.

Questions about this item

Does the 1.5 m cable generate noticeable heat or draw extra power during continuous 6.0 Gbps SAS transfers?

The passive twinaxial assembly has no active components, so it produces no measurable heat and adds no power draw beyond the transceivers at each end.

Which ports must my existing hardware provide for this SFF-8644 to SFF-8088 link to work?

One side needs an SFF-8644 (Mini SAS HD) receptacle and the other an SFF-8088 (Mini SAS) receptacle, both wired for 26-pin SAS 2.1/3.0 operation.

Will the 100-Ohm impedance and SAS 2.1 certification let me keep using older 3.0 Gbps SAS drives on the same controller?

Yes, the cable meets SAS 2.1 and 3.0 specs, so it negotiates down to 3.0 Gbps per lane automatically when connected to legacy drives.
