Vszerda 50cm SFF-8654 8i 74pin to Dual SFF-8643 4i SAS cable

SKU CH-R7WW-JCAYV

Connects a Slimline SFF-8654 8i 74pin backplane to dual SFF-8643 4i controllers at 24Gbps per channel over 50cm

Cable Length 50 cm

  • Connects SFF-8654 backplanes to dual SFF-8643 controllers
  • 50cm length fits tight server chassis layouts
  • 24Gbps per channel supports SAS 4.0 throughput
  • 74-pin Slimline design saves internal device space
  • Four-lane signal path meets PCIe Gen3/4 and SAS 4.0

Slimline SFF-8654 to dual SFF-8643 cable

This 50cm cable connects a backplane or enclosure with a Slimline SFF-8654 8i 74pin port to a controller equipped with two SFF-8643 Mini SAS HD connectors. It is built for internal wiring in servers, data-storage arrays and workstations that use SAS 4.0 or PCIe Gen3/4 links. The Slimline connector saves space inside dense chassis.

Four-lane 24Gbps SAS and 8GT/s PCIe per channel

Each of the four lanes carries 24Gbps for SAS traffic and 8GT/s for PCIe traffic, matching the SAS 4.0 and Ultraport SlimSAS SFF-8654 specifications. The 50cm length suits typical server backplane-to-controller runs but will not reach across full-height rack enclosures or between separate cabinets. Installers needing longer reach must source a different cable.

Replaces legacy Mini SAS HD to Mini SAS HD links

The assembly upgrades older SFF-8643-to-SFF-8643 cabling when the backplane moves to the narrower SFF-8654 74pin interface. It is not for installations that retain dual SFF-8643 ports on both ends or that require external eSATA connectivity.

Questions about this item

Will the 50cm Slimline SFF-8654 8i 74pin connector fit my existing backplane?

The cable uses a Slimline SFF-8654 8i 74pin connector on one end, designed for backplanes with that exact interface.

How can I verify the 24Gbps SAS link is active after installation?

Check the controller BIOS or operating system utility to confirm each of the four channels negotiates at the SAS 4.0 rate of 24Gbps per channel.

Does the package include both SFF-8643 4i connectors ready to plug into my controller?

The cable terminates in dual SFF-8643 4i Mini SAS HD connectors, providing the two controller links in a single assembly.
