Single SFF8654 8i SlimSAS connector splits to dual SFF8639 U.2 NVMe ports on 80cm cable

Fervit

Fervit SFF8654 8i to Dual SFF8639 NVMe U.2 Cable 80cm

SKU CH-NPHA-61VXQ

Splits one SFF8654 8i SlimSAS port into two SFF8639 U.2 connectors for NVMe, SAS and SATA drives with integrated power and data over an 80cm low-loss cable

  • Single SFF8654 8i port splits to dual SFF8639 U.2 NVMe ports for multi‑SSD expansion
  • Integrated power and data transmission supports NVMe, SAS and SATA solid‑state drives
  • 80cm length enables neat routing in high‑density server, NAS and storage backplane builds
  • Low‑loss wire construction delivers stable high‑speed bandwidth for enterprise storage performance
  • SlimSAS compact form factor saves internal chassis space for low‑profile dense server builds

Connection Breakout

This cable splits a single SFF8654 8i SlimSAS connector into two SFF8639 U.2 ports, enabling dual NVMe SSD expansion from one host interface. It is designed for administrators and integrators building high-density storage arrays in servers or NAS appliances.

Upgrade Path

The assembly replaces the need for multiple discrete cables or a larger backplane when adding a second U.2 drive to an existing SlimSAS port. The jump is worthwhile when a chassis has limited internal routing space but the controller supports bifurcation for two endpoints.

Sustained Operation

Low-loss wire construction maintains stable bandwidth during continuous enterprise workloads without signal degradation over the 80cm run. Integrated power and data delivery supports NVMe, SAS and SATA drives alike, while the slim form factor preserves airflow in densely packed bays during prolonged use.

Questions about this item

What connector does the cable use on the host side to fit a controller port?

The cable uses a single SFF8654 8i SlimSAS connector on the host side to break out to dual U.2 ports.

How is the cable installed and what step is commonly missed?

Connect the SFF8654 8i end to the controller and the two SFF8639 ends to the drives; the step often missed is ensuring each U.2 drive receives both data and power through the same connector.

What maintenance or replacement might this cable need later?

Inspect the 80cm cable and connectors for bent pins or insulation damage after any chassis rework; replace it if signal errors appear on the NVMe, SAS or SATA drives.
