Short 0.5m breakout cable with SFF8654 8i connector splitting to two SFF8643 ports, black shielded jacket

SMUGDESK

SMUGDESK Mini SlimSAS SFF8654 8i PCIe 4.0 to Dual SAS HD SFF8643 Cable .5m

SKU CH-P29F-FZE29

This breakout cable converts one PCIe 4.0 SFF8654 8i port into two SFF8643 SAS HD connections for multi-drive storage expansion

  • 1-to-2 breakout expands one SFF8654 8i port into dual SFF8643 SAS HD connections for multi-drive storage growth
  • Anti-misplug structure prevents reverse insertion, protecting server hardware during installation
  • 32AWG low-loss copper conductors deliver stable 24Gbps bandwidth for enterprise NVMe/SAS storage workloads
  • Precision shielding reduces signal crosstalk and attenuation in high-density rackmount server environments
  • Compact .5m length enables clean short-range internal routing for small-form-factor servers and workstations

Breakout Cable for PCIe 4.0 Storage

This breakout cable converts a single Mini SlimSAS SFF8654 8i PCIe 4.0 port into two independent SFF8643 SAS HD connectors. It enables multidrive storage expansion for enterprise servers and compact workstations requiring high-density internal interconnects.

Signal Integrity in Dense Chassis

Premium 32AWG low-loss copper conductors and precision shielding maintain stable 24Gbps bandwidth while reducing crosstalk and attenuation. The construction supports reliable performance under heavy RAID and storage workloads in high-density rackmount environments.

Anti-Misplug Design and Short Reach

A built-in anti-misplug structure prevents reverse insertion to protect server hardware during installation. The .5meter length allows clean short-range routing inside small-form-factor servers without excess cable clutter.

Questions about this item

How do I install the Mini SlimSAS SFF8654 8i to dual SFF8643 breakout cable without damaging the connectors?

Align the anti-misplug key on the SFF8654 8i plug with the PCIe 4.0 port, then press straight in until the latch clicks; repeat for each SFF8643 SAS HD connector, ensuring the key matches the drive backplane slot before applying force.

What maintenance will the 32AWG copper conductors and shielding need over time?

No scheduled maintenance is required; inspect the cable jacket and connector latches during routine server hardware checks and reseat only if a link error appears.

At what point does the .5m length limit signal integrity under sustained 24Gbps NVMe or SAS traffic?

The .5m design meets PCIe 4.0 and SAS electrical specs for 24Gbps operation, so sustained throughput is limited by the host controller or drive performance, not the cable itself.
