CableCreation Mini SAS SFF-8643 to SFF-8087 Cable 1.6FT

SKU CH-Q6JH-6N74P

Connects SFF-8643 to SFF-8087 for 6Gb/s or 12Gb/s SAS links, 1.6ft length

  • Connects SFF-8643 to SFF-8087 for internal storage
  • Supports SAS 2.1 at 6Gb/s and SAS 3.0 at 12Gb/s
  • SFF-8643 connector reduces PCB space for higher port density
  • Hybrid design enables smooth 6Gb to 12Gb transition
  • 6FT AWG 30 cable suits compact chassis builds

Internal SAS adapter cable

This 1.6 ft cable connects a Mini SAS SFF-8643 port to a legacy Mini SAS 36-pin SFF-8087 connector. It enables internal storage links between modern host controllers and older backplanes or enclosures. The hybrid design supports both SAS 2.1 at 6 Gb/s and SAS 3.0 at 12 Gb/s specifications. Builders upgrading density without replacing drives will find it useful.

Thermals and power in normal use

The AWG 30 conductors carry signal current with minimal resistive heating inside a chassis. No active cooling or external power is required for the passive assembly. Cable length of 0.5 m keeps insertion loss low for 12 Gb/s operation. Routing clearance depends on the specific enclosure layout.

What the bundled items change

No software, drivers or mounting hardware are included with this cable. The only change is the physical link between dissimilar Mini SAS generations. Compatibility relies on the host and device supporting the same SAS protocol version. Buyers needing additional cables or bracket kits must source them separately.

Questions about this item

How do I connect the SFF-8643 end to my controller and the SFF-8087 end to my backplane?

Align the keyed SFF-8643 plug with the controller port and press straight in until the latch clicks; do the same with the 36-pin SFF-8087 side on the backplane — forcing either connector at an angle bends the high-density pins.

Will the AWG 30 conductors degrade and need replacement?

The 30 AWG wires are rated for the cable's 12 Gb/s SAS 3.0 signal; they do not wear out in normal use, so replacement is only needed if the jacket is cut or a latch breaks.

What stops the link from running at 12 Gb/s over the 1.6 ft length?

The 0.5 m length and 30 AWG construction meet the SAS 3.0 electrical spec, so the first limit is the 6 Gb/s ceiling of any SAS 2.1 device attached to the SFF-8087 side.
