Fervit

Fervit Mini Slimline SAS SFF8654 4i 38P to U.2 SFF8639 24Gbps 32AWG 31.49 Inches SATA 15Pin Power Cable

SKU CH-A9JF-DD248

Converts a SFF8654 38pin Slimline SAS host port to a SFF8639 U.2 SAS or NVMe drive interface with integrated SATA 15pin power at 24Gbps

  • Converts SFF8654 38pin Slimline SAS to U.2 SFF8639 drive interface for enterprise storage
  • 24Gbps highspeed transmission supports SAS 3.1 and PCIe U.2 NVMe SSDs
  • Integrated SATA 15pin male power connector supplies stable power and simplifies internal wiring
  • 32AWG lowloss copper wire reduces signal attenuation and crosstalk
  • 49 inch length fits rackmount servers, RAID backplanes and highdensity enclosures

Slimline SAS to U.2 cable for dense servers

This Fervit adapter converts an SFF8654 38-pin Slimline SAS host port to an SFF8639 U.2 SAS or NVMe drive interface. It targets administrators building enterprise storage inside rackmount chassis, RAID backplanes or other high-density enclosures. The 31.49 inch length is tailored for tight internal routing.

Signal integrity and power delivery

A 32AWG low-loss copper conductor reduces attenuation and crosstalk across the link. The cable supports 24Gbps transmission and full SAS 3.1 compatibility without active cooling or external power bricks. An integrated SATA 15-pin male connector supplies drive power directly from the backplane, eliminating a separate power run.

Simplified internal wiring

The single assembly carries both 24Gbps data and 15-pin power, reducing cable count and improving airflow in compact bays. Builders who need to split one host port into multiple U.2 devices or who require a different connector pitch cannot use this fixed 4-lane design.

Questions about this item

How do I install the SFF8654 4i 38P to SFF8639 U.2 cable with SATA 15Pin power?

Connect the 38-pin Slimline SAS end to the host SFF8654 4i port, the 24Gbps SFF8639 end to the U.2 SAS or NVMe drive, and plug the SATA 15Pin male connector into the drive power socket; ensure the 31.49 inch cable routes without sharp bends.

What maintenance or replacement will the 32AWG Slimline SAS to U.2 cable need later?

No scheduled maintenance is required; inspect the 38-pin and 24-pin connectors for dust or bent pins during server service intervals and replace the cable if the 32AWG conductors show kinks or the latch tabs break.

What limit appears first on the 24Gbps SFF8654 to SFF8639 link under sustained use?

The 24Gbps SAS 3.1 signalling ceiling is reached before the 32AWG copper attenuates the signal, so sustained throughput caps at the host controller's 24Gbps lane rate.
