Dual-port SFF-8644 to SFF-8643 adapter

This Vszerda adapter converts two external Mini SAS HD SFF-8644 ports to internal SFF-8643 connectors on a single PCBA. It is built for servers or workstations that need to link external SAS enclosures to an internal RAID controller or HBA. The bracket set includes both low-profile and standard-profile options for flexible mounting.

Verify connector gender and lane count

Confirm that your controller presents female SFF-8643 ports and that the external cables terminate in male SFF-8644 plugs. The adapter is passive, so it does not perform protocol conversion or signal regeneration. Ensure your SAS topology supports the intended device count without exceeding the controller’s lane budget.

Passive design adds no active cooling or power draw

The board draws no auxiliary power and generates negligible heat, so it does not affect system thermals or acoustic profile. It complies with the SAS 2.1 specification at 12 Gb/s and uses connectors designated for the SAS 3.0 standard. No fan, heatsink or external power connection is required.
