  • 36-pin SFF-8643 to SFF-8644 connects internal controller to external enclosure
  • 1m length fits standard server chassis layouts
  • Compatible with LSI 9380-8E and Areca ARC-1883X controller cards
  • New cable ready for immediate deployment

Internal-to-external SAS cable

This 1 metre cable converts an internal SFF-8643 connector on a controller card to an external SFF-8644 port for direct enclosure attachment. It is built for administrators and builders who need to route 12Gb/s SAS links outside the chassis without an intermediate backplane.

Twelve-gigabit interface ceiling

The assembly is rated for the 12Gb/s SAS interface used by current hard drives and SSDs. Signal integrity is maintained across the 36-pin Mini SAS interface, but the cable cannot exceed the electrical limits of the 12G standard or compensate for controller firmware that does not negotiate the top speed.

One-metre reach for rack enclosures

At 1m (3.3ft) the cable comfortably spans from a host adapter to an adjacent JBOD or disk shelf in the same rack. Longer runs to distant cabinets or multi-rack deployments will require the 2m (6.6ft) variant or active extension, because passive copper cannot reliably carry 12G signalling beyond this length.

Questions about this item

Should I pick the 1 m or 2 m version for my server build?

Choose 1 m for tight internal routing to an external enclosure; choose 2 m if the controller card and external chassis are farther apart.

What does the 12 Gb/s rating mean when the cable is installed?

It allows each lane to carry up to 12 Gb/s between a 12G SAS controller and attached drives or enclosures.

How do the SFF-8643 and SFF-8644 connectors limit the link?

The internal SFF-8643 plugs into the controller and the external SFF-8644 connects the enclosure, capping the link at 12 Gb/s per lane.
