SlimSAS SFF8654 8i to dual SAS HD SFF8643 cable 1M

SMUGDESK

SMUGDESK Mini SlimSAS SFF8654 8i Gen 4.0 to Dual SAS HD SFF8643 Cable 1M

SKU CH-M57S-QFM0F

Converts one SlimSAS SFF8654 8i port into dual SAS HD SFF8643 connections for 24Gbps storage expansion with anti-misdirection keying

  • PCIe Gen 4.0 SlimSAS SFF8654 8i breakout to dual SAS HD SFF8643 ports for multichannel storage expansion
  • Antimisdirection keying prevents reverse insertion, avoiding hardware damage during installation
  • 32AWG low-loss copper wire delivers stable 24Gbps ultra-high-speed signal transmission
  • 1meter length supports flexible routing in standard rackmount servers and high-density backplanes
  • Enterprise-grade shielding reduces crosstalk, compatible with NVMe SSDs, RAID controllers and storage arrays

Gen4 SlimSAS to Dual SAS HD Cable

This Gen4 Mini SlimSAS SFF8654 8i cable breaks out into two independent SAS HD SFF8643 ports for multichannel storage expansion. It uses 32AWG lowloss copper conductors to deliver stable 24Gbps signal transmission. The 1meter length supports flexible routing in standard rackmount servers and highdensity backplanes. Enterprisegrade shielding reduces crosstalk for reliable operation.

Suits Servers Using SFF8654 8i Interfaces

Builders connecting NVMe SSDs, RAID controllers or storage arrays to a single SFF8654 8i port will find this breakout cable suitable. Buyers whose equipment uses different connector types or requires a straightthrough SFF8654 cable should look at other interconnects. The antimisdirection keying prevents reverse insertion during installation.

SFF8654 8i to Dual SFF8643 Breakout

The defining specification is the conversion of one SFF8654 8i interface into two separate SFF8643 ports. This breakout topology determines whether the cable matches the port layout of the host controller and target backplane. Verify the controller and drive cage connectors before purchase.

Questions about this item

Will the SFF8654 8i connector or the dual SFF8643 ends need periodic replacement?

The cable is a passive copper assembly with no moving parts; the connectors are rated for standard server insertion cycles and do not have a scheduled replacement interval.

What limits throughput first when the link runs at 24Gbps continuously?

Signal integrity over the 32AWG copper at 1 metre is the primary constraint; the heavy‑duty shielding keeps crosstalk low so the 24Gbps Gen4 rate remains stable under sustained load.

Does the cable generate noticeable heat or draw extra power during all‑day operation?

As a passive interconnect it consumes no power itself and produces negligible heat; any thermal rise comes from the attached NVMe SSDs or RAID controllers, not the cable.
