Mini SAS HD SFF8643 4i breakout cable to dual SFF8639 U.2 ports with SATA 15pin power connector, .5m length

SMUGDESK

SMUGDESK Mini SAS HD SFF8643 4i to Dual SFF8639 SATA 15Pin Power Cable .5m 12Gbps 32AWG

SKU CH-VTB3-AEW20

Connects a single SFF8643 4i port to dual SFF8639 U.2 drives with integrated SATA 15pin power, supporting 12Gbps over 32AWG copper at .5m

  • Converts one SFF8643 4i port into two SFF8639 U.2 drive connections
  • Integrated SATA 15pin power feeds U.2 SSDs directly without extra cables
  • 32AWG lowloss copper wire maintains stable 12Gbps bandwidth for NVMe drives
  • Compact .5m length keeps rackmount and workstation wiring clean and tidy
  • Works with server motherboards, RAID controllers and U.2 NVMe solidstate drives

Server storage breakout

This cable converts a single Mini SAS HD SFF8643 4i port into two SFF8639 U.2 drive connectors for highspeed NVMe storage expansion. An integrated SATA 15pin power plug feeds the drives directly, reducing internal cable count inside rackmount servers and workstations. The 32AWG copper conductors are rated for 12Gbps bandwidth across the .5m length.

Simple internal routing

The .5m length keeps excess slack to a minimum, making it easier to route cleanly through dense backplanes and tight chassis. Both data and power connections are combined in one assembly, so there is no separate power lead to manage. Builders should verify that the host controller and U.2 drives both use the SFF8639 pinout before installing.

Highdensity U.2 deployments

This suits administrators adding a pair of U.2 NVMe SSDs to a server or RAID controller that exposes an SFF8643 4i port. It does not suit systems that require a longer reach between controller and backplane, nor builds where the drives need a different power connector or a singleport breakout.

Highlights

  • Converts one SFF8643 4i port into two SFF8639 U.2 drive connections
  • Integrated SATA 15pin power feeds U.2 SSDs directly without extra cables
  • 32AWG lowloss copper wire maintains stable 12Gbps bandwidth for NVMe drives
  • Compact .5m length keeps rackmount and workstation wiring clean and tidy
  • Works with server motherboards, RAID controllers and U.2 NVMe solidstate drives

Questions about this item

How can I confirm the cable is delivering 12Gbps throughput after installation?

Verify the link speed in your RAID controller BIOS or OS storage utility; it should report a negotiated 12Gbps connection for each attached U.2 NVMe SSD.

What comes with the cable and what must I source separately?

The single assembly includes the SFF8643 4i plug, dual SFF8639 U.2 connectors and an integrated SATA 15pin power lead; you only need compatible U.2 NVMe drives and a motherboard or controller with an SFF8643 4i port.

Which length or version should I pick for a standard rackmount server?

This model is offered in a .5m length with 32AWG copper wire, suited for tidy internal routing in 1U or 2U chassis; choose it when the controller-to-backplane distance is short.
