Black flat SFF8654 4i to SFF8643 SAS cable, .8m

SMUGDESK

SMUGDESK MCIO Slimline SFF8654 4i to HD SFF8643 SAS Cable .8m 12Gbps 85Ohm

SKU CH-9MVQ-D4HZ1

Connects MCIO Slimline SFF8654 4i to HD SFF8643 for 12Gbps SAS with 85Ohm impedance in .8m flat cable

  • Gen5-ready cross-interface connectivity links SFF8654 4i to SFF8643
  • 85 Ohm impedance-matched conductors maintain stable signal integrity and low-loss transmission
  • Sleek black flat connector saves space and keeps internal server wiring tidy
  • Steady 12 Gbps bandwidth supports RAID controllers, backplanes and storage drives
  • 8 m length fits high-density rackmount server and storage node routing

Server storage link

This cable connects an MCIO Slimline SFF8654 4i port to an HD SFF8643 connector for SAS storage links inside servers and storage arrays. It targets system builders and IT teams wiring RAID controllers, backplanes or drive bays in rackmount chassis. The 0.8 metre reach suits dense 1U or 2U layouts where longer cables would block airflow.

Signal integrity build

Conductors are matched to 85 Ohm impedance to keep 12 Gbps signals clean across the cross-interface link. Heavy anti-interference shielding cuts crosstalk between lanes, while the black flat connector profile slips into tight backplane headers without crowding adjacent ports. The fixed 0.8 metre length removes slack that can snag during drive swaps.

Ready to route

No adapters, brackets or software are bundled; the cable is a single passive assembly that works immediately when seated. Its plug-and-play nature means storage nodes and NAS builds can be cabled and validated without driver installs or firmware steps. Buyers needing longer runs or different connector orientations will need a separate cable.

Questions about this item

Does the SFF8654 4i to SFF8643 cable maintain 12Gbps throughput?

The 85Ohm impedance-matched conductors and Gen5-ready design deliver steady 12Gbps bandwidth for RAID controllers and backplanes.

Will the flat black connector fit inside a high-density 1U server chassis?

The sleek flat-style connector saves space and the 0.8m length is optimized for compact rackmount routing.

How do I correctly seat the MCIO Slimline SFF8654 4i end without damaging the latch?

Align the keyed connector, press straight in until the latch clicks, and avoid angling the plug during insertion.
