Black flat cable with SlimSAS SFF-8654 8i to 8X connectors, low-profile design, 0.8m length

SMUGDESK

SMUGDESK SlimSAS SFF-8654 8i to 8X Cable 24Gbps 85Ω .8m

SKU CH-6C2D-YZEHM

Connects SFF-8654 8i to SFF-8654 8X at 24 Gbps with 85 Ω impedance and anti-misplug design for dense servers

  • Low-profile flat-to-flat design saves space and airflow in dense servers
  • 24 Gbps PCIe-compliant speed supports NVMe SSDs and RAID controllers
  • Strict 85 Ω impedance matching ensures stable signal integrity with minimal crosstalk
  • Anti-misplug design prevents reverse insertion and protects hardware
  • 8 m optimised length enables neat internal routing in rackmount systems

What this cable connects

This SlimSAS cable links an SFF-8654 8i port to an SFF-8654 8X port inside servers and workstations. It is built for 24Gbps PCIe-grade storage traffic such as NVMe SSD arrays and enterprise RAID controllers. The .8m flat-to-flat design fits low-profile chassis where space and airflow are tight. The black jacket helps identify the run in dense cable looms.

Installing and common pitfalls

The anti-misplug key stops the connector from seating backwards, so align the notch before pressing. Route the flat ribbon clear of sharp chassis edges and fan blades to avoid insulation damage. Do not bend tighter than the cable’s natural curve; excessive folding degrades the 85ohm impedance and causes link errors. Verify both ends click fully home — partial insertion is the most frequent cause of dropped drives.

Check before ordering

Confirm your controller and backplane both expose SFF-8654 8i and 8X receptacles respectively; the pinout is not interchangeable with other SlimSAS variants. Ensure the .8m reach covers the exact path between the two ports without strain. The chassis must accept a flat low-profile ribbon in the intended routing channel. This cable carries SAS and NVMe protocols only — it will not suit InfiniBand or legacy SCSI links.

Questions about this item

How do I verify the cable is running at 24Gbps after installation?

Check the controller BIOS or OS utilities for a negotiated link speed of 24Gbps on each lane; the 85Ω impedance and anti-misplug design ensure the connection stays locked at that rate.

What comes in the box and is anything else required?

The package contains the .8m SlimSAS SFF-8654 8i to 8X cable only; compatible PCIe NVMe drives, backplanes or RAID controllers must be sourced separately.

Which version should I choose for a low-profile 24Gbps server build?

Select this low-profile flat-to-flat SFF-8654 8i to 8X cable; its .8m length, 85Ω impedance and anti-misplug design are built for dense 24Gbps NVMe and SAS server chassis.
