  • Dual ports connect external 8644 hosts to internal 8643 devices
  • Low-profile bracket fits standard PCI slots for compact chassis
  • 12 Gb/s SAS bandwidth handles high-throughput storage workloads
  • Works on host or device side for flexible cabling
  • Female PCBA connectors ensure secure Mini SAS HD mating

Two-port SFF-8643 to SFF-8644 adapter

This adapter connects external SFF-8644 host connectors to internal SFF-8643 device connectors. It functions on both the host and device side of a SAS link. A low-profile bracket enables installation in standard PCI slots. The unit supports data transfer rates up to 12Gb/s.

Replacing mismatched Mini SAS HD cables

Use this adapter when your controller or backplane presents an SFF-8644 port but your drive enclosure or cable uses SFF-8643. The jump is worth it whenever a direct SFF-8644-to-SFF-8643 cable is unavailable or too short for your chassis layout. It bridges the connector gap without active electronics.

Sustained 12Gb/s throughput under load

The passive PCB maintains signal integrity for continuous 12Gb/s SAS traffic across both ports. No active components mean there is no thermal throttle point during extended transfers. Performance scales with the connected controller and drive capabilities rather than the adapter itself.

Questions about this item

What bracket profile does this adapter use to mount in a PCI slot?

It ships with a full PCI-slot profile mounting bracket that secures the two SFF-8643 ports to the chassis.

Which orientation should the SFF-8644 and SFF-8643 connectors face during installation?

The SFF-8644 side connects to the external host cable while the SFF-8643 side faces the internal backplane or drive cage.

When should the adapter be replaced if the 12 Gb/s link becomes unreliable?

Replace it if reseating cables does not restore a stable 12 Gb/s SAS link or if the connector latches no longer hold firmly.
