Slimline SAS SFF8654 8i to dual MCIO 4i breakout cable with full-cover anti-misplug housing, 1M length

SMUGDESK

SMUGDESK Slimline SAS SFF8654 8i to Dual MCIO 4i Cable 1M 16Gbps AntiMisplug FullCover

SKU CH-S9DW-ZSSH6

Splits one SFF-8654 8i port into two MCIO 4i connections for NVMe storage expansion at 16 Gbps with anti-misplug protection

  • 1to2 breakout converts single SFF8654 8i to dual MCIO 4i for storage expansion
  • FullCover antimisplug housing prevents reverse insertion protecting server hardware
  • 16Gbps bandwidth supports enterprise NVMe SSDs and RAID controllers
  • Lowloss copper conductors minimise signal attenuation for stable operation
  • 1meter length enables tidy internal routing in rackmount servers

Slimline SAS SFF8654 8i Breakout Cable

This new SMUGDESK cable converts a single Slimline SAS SFF8654 8i port into two independent MCIO 4i interfaces for server storage expansion. The fullcover antimisplug housing prevents reverse insertion, protecting hardware during installation. Premium lowloss copper conductors deliver steady 16Gbps bandwidth for enterprise NVMe SSDs and RAID controllers. The 1meter length supports tidy internal routing in rackmount servers and highdensity workstations.

Server Builders Expanding NVMe Storage

This breakout cable suits administrators adding dual MCIO 4i drives to a single SFF8654 8i controller port in standard rackmount chassis. The antimisplug design reduces installation risk in dense environments where blind mating occurs. Builders needing longer runs for fullheight tower servers or direct backplane cabling without a breakout should look at alternative cable assemblies. It does not serve connections requiring InfiniBand or standard Mini SAS HD interfaces.

16Gbps Signal Integrity Over Copper

The 16Gbps rating determines whether this harness matches the throughput demands of modern NVMe solidstate drives and RAID arrays. Lowloss copper construction minimizes attenuation and crosstalk across the 1meter span to maintain link stability. If the target controller or drives operate at a different signalling rate, the cable will not negotiate the required performance tier. Verify the 16Gbps requirement before deployment.

Questions about this item

What connector must my backplane or HBA provide for the SFF8654 8i end of this cable?

Your backplane or HBA needs a single Slimline SAS SFF8654 8i receptacle to accept the primary connector on this harness.

Can I keep my existing MCIO 4i NVMe drives when adding this breakout cable?

Yes, the dual MCIO 4i tails plug directly into standard MCIO 4i NVMe devices, so current drives stay compatible.

How do I verify the 16Gbps link is active after installation?

Check the controller BIOS or OS device tree for each MCIO 4i port reporting a 16Gbps SAS link speed and zero errors.
