LORDWORLD Ultraport Slimline SFF-8654 8i 74pin to Dual SFF-8643 4i 50cm SAS 4.0 Cable

SKU CH-P7SV-RRKEB

Connects a Slimline SFF-8654 8i 74pin port to dual SFF-8643 4i connectors at 50cm length for SAS 4.0 links

  • Connects Slimline SFF-8654 to dual SFF-8643 ports
  • 50 cm length fits compact chassis
  • 74-pin connector supports SAS 4.0 specification
  • Dual 4i layout doubles drive connectivity
  • PCIe Gen3/4 compliance ensures broad host compatibility

Slimline SAS 4.0 cable for dense storage arrays

This LORDWORLD Ultraport Slimline assembly connects a single SFF-8654 8i 74pin port to two SFF-8643 Mini SAS HD connectors. It is built for servers and workstations that need to break out one wide internal port into two narrower links. The 50cm length suits compact chassis routing.

Meets PCIe Gen3/4 and SAS 4.0 specification under

The cable assembly is rated to the SAS 4.0 electrical standard, supporting signalling rates used by PCIe Gen3 and Gen4 storage controllers. Shielded construction maintains signal integrity during continuous high-throughput transfers across both SFF-8643 branches. No active components are present; performance depends on the host controller and drive endpoints.

Verify your backplane

You need one Slimline SFF-8654 8i 74pin source connector and two SFF-8643 Mini SAS HD target ports on the backplane or drive cage. Confirm the controller supports bifurcation or dual-port operation on that Slimline lane group. The 50cm reach limits placement to adjacent drive bays or nearby backplanes.

Questions about this item

Does the 50 cm Slimline SFF-8654 8i 74pin cable generate noticeable heat or draw extra power when running continuously?

The passive cable assembly carries signals without active components, so it adds no measurable heat or power draw during all-day operation.

What controller or backplane must I already have to use the dual SFF-8643 Mini SAS HD connectors?

You need a host bus adapter or motherboard with Slimline SFF-8654 8i 74pin ports that support PCIe Gen3/4 and SAS 4.0 signalling.

Will the SFF-8654 8i 74pin end mate with older SFF-8643 4i ports on my existing backplane?

No, the Slimline SFF-8654 8i 74pin connector is physically and electrically different from legacy SFF-8643 4i ports, so a direct connection is not possible.
