Vszerda SFF-8654 8i 74pin to Dual SFF-8643 4i Mini SAS HD Cable 50cm

SKU CH-AQHH-HE75Z

Connects a Slimline SFF-8654 8i 74pin backplane to dual SFF-8643 4i Mini SAS HD controllers at 24Gbps SAS and 8GT/s PCIe per channel over 50cm

Cable Length 100 cm

  • Slimline 74-pin connector saves space in dense servers
  • Dual SFF-8643 ends link one port to two controllers
  • 50 cm length fits tight chassis routing cleanly
  • 24 Gbps per channel meets SAS 4.0 performance needs
  • PCIe 4.0 and SAS 4.0 compliant for modern platforms

Cable purpose and audience

This 50cm cable adapts an internal SFF-8654 8i 74pin Slimline port to two SFF-8643 Mini SAS HD connectors. It suits server, storage and workstation builders who need to link a backplane or drive cage to a controller using SAS 4.0 or PCIe Gen3/4 signalling at 24Gbps per channel.

Who it suits and who it does not

The assembly works for installers who require a slim, four-lane breakout inside a chassis. It does not meet the needs of buyers who want a straight 8i-to-8i link, external Mini SAS cabling, or connectors other than SFF-8654 and SFF-8643.

Deciding specification

The cable carries 24Gbps per channel under SAS 4.0 and 8GT/s under PCIe Gen3/4. Verify that both the source device and the target controller support these speeds and the 74pin Slimline plus dual SFF-8643 pinouts before purchasing.

Highlights

Questions about this item

Should I pick the 50 cm or 100 cm length for my server build?

The 50 cm cable fits tight chassis routing between a backplane and controller; choose 100 cm only if devices are farther apart.

What does 24 Gbps per channel deliver in a live system?

Each of the four lanes runs at 24 Gbps SAS or 8 GT/s PCIe Gen4, giving full SlimSAS 4.0 bandwidth to attached drives.

How does the SFF-8654 to dual SFF-8643 interface limit performance?

The 74-pin Slimline 8i plug splits into two 4i Mini SAS HD connectors, capping each path at four lanes of SAS 4.0 or PCIe Gen4 speed.
