Flat 0.5 m cable with one SFF-8654 8i plug splitting to two SFF-8654 4i plugs

SMUGDESK

SMUGDESK Gen5 MCIO 8X Slimline SAS 8i to Dual SFF8654 4i Cable 0.5m

SKU CH-RN4F-BMGTR

Splits one SFF-8654 8i port into two SFF-8654 4i ports for 24 Gbps NVMe storage expansion with 85-ohm impedance and .5 m length

  • PCIe 5.0 Gen5 certified breakout splits one SFF8654 8i port into dual 4i interfaces
  • Stable 24Gbps bandwidth supports enterprise NVMe SSDs and high-performance RAID controllers
  • Strict 85ohm impedance matching ensures precise signal integrity with minimal crosstalk
  • Premium low-loss copper conductors deliver reliable long-term datacenter storage performance
  • Compact .5m length enables clean internal routing in high-density rack servers

PCIe 5.0 breakout cable

This SMUGDESK Gen5 cable converts a single SFF8654 8i port into two independent SFF8654 4i interfaces. It is built for PCIe 5.0 systems that need to connect multiple NVMe drives or RAID controllers from one slimline SAS port. The .5 meter length suits tight server and workstation chassis. Precise 85 ohm impedance matching protects signal integrity at speed.

Suits multi-drive NVMe arrays

Builders expanding a single controller port into two separate 4i links for NVMe SSDs or RAID arrays will use this cable. It supports 24Gbps transfer rates required by modern enterprise storage. Administrators needing longer reach between backplanes or external enclosures should look at alternative lengths. Systems limited to PCIe 4.0 or older SAS standards cannot utilise the Gen5 bandwidth this cable provides.

Verify port layout and clearance

Confirm the host controller or backplane presents a genuine SFF8654 8i connector before ordering. Ensure the target drives or RAID cards accept SFF8654 4i plugs. Check that the .5 meter run covers the internal routing path without strain. Validate that the platform firmware and drivers support PCIe 5.0 bifurcation for the dual 4i split.

Questions about this item

What controller port does this cable plug into?

The cable connects to a single Slimline SAS SFF-8654 8i port on a PCIe 5.0 Gen5 controller.

Will the dual SFF-8654 4i ends work with existing 85ohm impedance backplanes?

Yes, the cable maintains strict 85ohm impedance matching for signal integrity with compatible backplanes.

How can I confirm the link is running at 24Gbps after installation?

Check the controller firmware or OS utilities for a negotiated 24Gbps link speed on each NVMe drive.
