Slimline SFF-8654 8i connector splitting to two SFF-8643 Mini SAS HD ends, 100 cm cable

Vszerda

Vszerda SFF-8654 8i 74pin to Dual SFF-8643 4i SAS cable 100cm

SKU CH-D5PP-DWXM4

Connects a Slimline SFF-8654 8i 74pin backplane to dual SFF-8643 controllers at 24Gbps per channel over 100cm

  • Slim 74-pin connector saves space in dense chassis
  • Dual 4i Mini SAS HD links backplane to controller
  • 24 Gbps per channel supports SAS 4.0 throughput
  • 100 cm length fits standard server cable routing
  • PCIe 4.0 and SAS 4.0 specification compliance ensures signal integrity

Connection overview

This Vszerda cable links a Slimline SFF-8654 8i 74pin port to two SFF-8643 Mini SAS HD connectors. It is built for internal server, data-storage and workstation installations where a backplane or controller uses the Ultraport SlimSAS interface. The 100cm length gives routing flexibility inside standard chassis. New condition ensures clean contacts and reliable signal integrity.

Speed rating

Each channel carries 24Gbps for SAS traffic and 8GT/s for PCIe, meeting the SAS 4.0 and PCIe Gen3/4 specifications. The four-lane design delivers the full bandwidth required by modern storage arrays without bottlenecks. Shielded construction supports the stated data rates across the full cable length.

Fit and alternatives

Suits builders who need a single 74-pin Slimline connection split to dual Mini SAS HD ports in a 100cm reach. Not for buyers who require a different pin count, a straight-through single-end cable, or a shorter 50cm assembly for tight enclosures.

Questions about this item

What does the 24 Gbps per channel rating mean when the cable is installed in a server?

Each of the four lanes carries data at up to 24 Gbps for SAS traffic or 8 GT/s for PCIe Gen3/4, so the assembly moves up to 24 Gbps per lane between a Slimline 8654 backplane and a dual 8643 controller.

How does the SlimSAS 4.0 interface limit performance in practice?

The cable meets SAS 4.0 and PCIe Gen3/4 specifications, capping each lane at 24 Gbps for SAS or 8 GT/s for PCIe, which is the maximum the Slimline 8654 and 8643 connectors support.

What clearance and connector space does the 100 cm assembly need to fit?

The cable uses a Slimline SFF-8654 8i 74-pin plug on one end and two SFF-8643 Mini SAS HD plugs on the other, with a 100 cm length that routes between a backplane and a controller in standard server chassis.
