SlimSAS SFF-8654 8i cable splits to dual MCIO 4i connectors, .5m shielded copper, 12Gbps

SMUGDESK

SMUGDESK SlimSAS SFF-8654 8i to Dual MCIO 4i Cable .5m 12Gbps

SKU CH-G9G8-EFMVG

SlimSAS SFF-8654 8i breakout to dual MCIO 4i ports at 12Gbps for NVMe and RAID, .5m shielded low-profile design

  • Converts one SFF-8654 8i port to dual MCIO 4i for flexible storage expansion
  • Delivers stable 12 Gbps bandwidth for NVMe SSDs and RAID controllers
  • Ultra-slim low-profile design optimises airflow in compact server chassis
  • Shielded copper wiring reduces signal loss, crosstalk and EMI
  • 5 m short length enables neat routing in tight internal spaces

SlimSAS SFF-8654 8i Breakout Cable

This SMUGDESK cable converts a single SFF-8654 8i port into two MCIO 4i connectors. It targets server and workstation builders who need to attach multiple NVMe drives or RAID controllers from one slot. The .5 metre length suits dense chassis where longer runs would obstruct airflow.

Low-Profile Installation Notes

The ultra-slim low-profile hood fits tight backplanes and shallow drive cages without blocking adjacent cards. Shielded copper conductors resist crosstalk and electromagnetic interference during routing. Ensure both MCIO 4i receptacles match the pinout of your target drives; mismatched keying is the most common cause of link failure.

Sustained 12Gbps Operation

Rated for 12Gbps throughput, the assembly maintains signal integrity under continuous NVMe and RAID workloads. Short 19.68in traces minimise attenuation so saturation remains steady during extended rebuilds or streaming writes. Thermal throttling is not a factor for the passive cable itself, but downstream controller limits still apply.

Questions about this item

How can I verify the cable is delivering the rated 12Gbps link speed after installation?

Check the RAID controller or HBA management utility for each MCIO port; both should report a negotiated 12Gbps SAS link with zero CRC errors during sustained NVMe SSD traffic.

What connectors are included on the cable and are any adapters required for a standard SFF-8654 8i RAID card?

One SFF-8654 8i plug and two MCIO 4i plugs are factory-terminated; no extra adapters are needed to connect a compatible low-profile RAID controller to two MCIO backplanes.

When should I choose the .5m length over a longer run for my server build?

Select the .5m cable when the RAID controller and MCIO backplanes sit in the same compact chassis and you need the shortest route to maintain signal integrity and airflow.
