Fervit Mini SAS HD SFF8643 4i to Dual SFF8639 with SATA 15Pin Power Cable 12Gbps 32AWG 1M

SKU CH-2ACD-6M1HD

Converts a single SFF8643 4i Mini SAS HD port to dual SFF8639 U.2 NVMe interfaces with integrated SATA 15-pin power for 12Gbps server storage expansion

  • Expands one SFF8643 4i port to dual SFF8639 U.2 NVMe drives for multi‑SSD growth
  • Integrated SATA 15Pin power connector supplies stable power to U.2 drives reducing cable clutter
  • 12Gbps SAS/NVMe bandwidth supports enterprise storage arrays and RAID deployments
  • 32AWG pure copper wire minimises signal loss and crosstalk for reliable long‑term operation
  • 1M length enables tidy internal routing in standard rack servers and workstations

Server NVMe Expansion Cable

This Fervit cable converts a single Mini SAS HD SFF8643 4i port into two SFF8639 U.2 connectors for NVMe SSD multi-drive expansion in enterprise servers and workstations. An integrated SATA 15pin power feed supplies stable power to both U.2 drives, reducing internal cable count. The one-metre length suits standard rack chassis routing.

12Gbps SAS and NVMe Bandwidth

The assembly supports 12Gbps data transfer across SAS and NVMe protocols, the specification that determines whether the link can sustain enterprise storage array and RAID workloads. 32AWG pure copper conductors minimise signal attenuation and crosstalk at this rate. Compatibility depends on the host controller and drive firmware supporting the same signalling standard.

Sustained Enterprise Workloads

Low-loss 32AWG wiring and the dedicated power delivery maintain signal integrity and drive stability during continuous high-queue-depth operations typical of RAID rebuilds and database volumes. The fixed one-metre reach avoids excess slack that can impede airflow in densely populated chassis. Builders needing longer runs or additional drive ports will require a different interconnect solution.

Questions about this item

What does the 12Gbps rating mean for my NVMe drives?

The cable supports 12Gbps SAS and NVMe bandwidth per lane, so each U.2 drive can run at full PCIe Gen3 x4 speed without the cable becoming the bottleneck.

How does the SFF8643 4i connector limit the connection?

The single SFF8643 4i port carries four lanes that are split to two SFF8639 U.2 connectors, giving each drive two lanes unless your controller and backplane negotiate a x4 link per drive.

What clearance and power connections does the 1m assembly need?

It requires one free SFF8643 4i Mini SAS HD header and a SATA 15-pin power plug; the 1-metre length and 32AWG wire allow tidy routing inside standard rack servers and workstations.
