Connectivity for SAS HD and legacy ports

This two-pack provides internal Mini SAS HD SFF-8643 to SFF-8087 cables measuring 1.64 ft each. They link 12Gbps SAS controllers or backplanes with SFF-8643 ports to drives or enclosures that use the older SFF-8087 interface. The 100 Ohm impedance and SAS 2.1 compliance suit storage arrays and server builds needing that specific crossover.

Build integration and cable routing

Each cable connects a high-density SFF-8643 plug to a legacy SFF-8087 receptacle, freeing the builder from hunting adapters. The short 1.64 ft length keeps internal routing tidy inside 2U or 4U chassis where backplane-to-HBA runs are brief. Two cables in the pack cover dual-port HBAs or redundant paths without extra orders. Black jacketing blends with standard server loom.

Sustained throughput behaviour

Rated for up to 12Gbps per lane, the assembly maintains signal integrity at the full SAS 2.1 spec during extended rebuilds or sequential streaming workloads. The fixed 100 Ohm impedance reduces reflections that can cause link retraining under continuous load. No active components mean latency stays constant regardless of duty cycle.

Questions about this item

What is the maximum data rate this SFF-8643 to SFF-8087 cable supports?

The cable is rated for up to 12 Gbps data rates, suitable for 12G SAS connections.

Does the 100 Ohm impedance spec help control heat during all-day operation?

The 100 Ohm impedance maintains signal integrity; passive cables like this generate negligible heat themselves.

Which controller ports must I have to use this SFF-8643 to SFF-8087 cable?

You need one device with an SFF-8643 (Mini SAS HD) port and another with an SFF-8087 (Mini SAS) port.
