Slimline SAS SFF-8654 8i to dual MCIO 4i breakout cable, .8 m, 16 Gbps

SMUGDESK

SMUGDESK Slimline SAS SFF-8654 8i to Dual MCIO 4i Cable .8m 16Gbps

SKU CH-YWPZ-ZJFGE

Breakout cable converts one SFF-8654 8i port into dual MCIO 4i links at 16 Gbps with anti-misplug housing and .8 m length

  • Converts one SFF-8654 8i port into two MCIO 4i links for flexible storage expansion
  • Anti-misplug full-cover housing prevents reverse insertion and protects server hardware
  • 16 Gbps bandwidth supports enterprise NVMe SSDs and RAID controllers
  • Low-loss copper harness reduces signal attenuation for reliable long-term operation
  • 8 m length enables tidy internal routing in compact rack servers

Purpose-built breakout cable

The SMUGDESK Slimline SAS SFF-8654 8i to Dual MCIO 4i cable converts one 8-lane port into two independent 4-lane interfaces for dense server storage expansion. It targets system integrators and IT teams adding enterprise NVMe SSDs or RAID controllers to compact rackmount chassis where internal cabling space is tight.

Straightforward internal routing

The 0.8 metre length keeps runs short inside 1U or 2U servers, reducing clutter and improving airflow. A full-cover anti-misplug housing prevents reverse insertion, so the connector seats correctly on the first attempt and protects backplane pins from bending during maintenance windows.

16 Gbps per lane headroom

Each of the eight lanes sustains 16 Gbps, giving ample bandwidth for current-gen NVMe drives and hardware RAID arrays under heavy mixed workloads. The low-loss copper harness keeps signal integrity clean at this speed, but the fixed .8 metre reach limits use to intra-chassis links; longer runs to external JBODs or adjacent racks will require a different cable.

Questions about this item

How can I confirm the cable is operating at 16Gbps after installation?

Check the RAID controller or HBA management utility for link speed reporting 16Gbps on each MCIO 4i lane and run a sustained NVMe workload to verify throughput stability.

What comes in the box and do I need extra connectors for SFF8654 8i and MCIO 4i ports?

The box contains the single .8m breakout cable with integrated SFF8654 8i and dual MCIO 4i ends; no separate adapters or brackets are required for direct server backplane connection.

Should I choose the .8m length or a longer version for a compact 1U rack server?

The .8m (31.49in) length is purpose-built for short internal runs in compact 1U and 2U chassis, reducing cable clutter and signal loss compared with longer alternatives.
