SFF8643 Mini SAS HD breakout cable splitting to four SFF8482 29pin connectors with integrated 15pin power, 1M shielded length

SMUGDESK

SMUGDESK SFF8643 Mini SAS HD to 4× SFF8482 29Pin Breakout Cable 1M 12Gb/s SAS 3.0 15Pin Power

SKU CH-0AYS-FWGZX

Connects one SFF8643 host port to four SFF8482 drives with integrated 15pin power at 12Gb/s SAS 3.0 speed

  • Connect four drives from one controller port using SFF-8643 to 4× SFF-8482 breakout
  • 12 Gb/s SAS 3.0 bandwidth with 6 Gb/s and 3 Gb/s backward compatibility
  • Integrated 15-pin power on each SFF-8482 connector removes separate SATA power cables
  • Shielded 1 m cable with anti-interference design supports 24-hour server operation
  • Purpose-built for RAID host adapters in NAS, workstation and enterprise storage deployments

Host Port and Drive Compatibility

This cable connects a single SFF8643 Mini SAS HD host port on a RAID controller or HBA to four SFF8482 29pin drive interfaces. It supports both SAS and SATA hard drives using the SAS 3.0 specification at up to 12Gb/s per channel. Backward compatibility extends to 6Gb/s and 3Gb/s devices. Each drive connector integrates 15pin power contacts so no separate SATA power cables are required for the attached drives.

Controller and Chassis Checks

Verify that your RAID adapter or HBA provides an SFF8643 Mini SAS HD port and that the card firmware supports the attached drive types. Ensure the server chassis has sufficient internal clearance for a 1meter shielded cable run from the controller to the drive bays. Confirm the drives use the 29pin SFF8482 interface; other connector styles will not mate. The host end is controlleroriented and must plug into the RAID card.

Upgrade From MultiCable Setups

Replaces separate signal cables and individual SATA power cords with one integrated assembly, reducing internal clutter and potential failure points. The jump is worthwhile when consolidating four drive connections onto a single controller port while maintaining 12Gb/s bandwidth per channel. It also suits deployments needing 24hour operation where highdensity shielding helps prevent signal crosstalk under sustained load.

Highlights

  • Connect four drives from one controller port using SFF-8643 to 4× SFF-8482 breakout
  • 12 Gb/s SAS 3.0 bandwidth with 6 Gb/s and 3 Gb/s backward compatibility
  • Integrated 15-pin power on each SFF-8482 connector removes separate SATA power cables
  • Shielded 1 m cable with anti-interference design supports 24-hour server operation
  • Purpose-built for RAID host adapters in NAS, workstation and enterprise storage deployments

Questions about this item

Does the SFF8643 Mini SAS HD cable include power for the four SFF8482 drives or do I need separate SATA power cables?

Each SFF8482 connector carries integrated 15pin power contacts, so the single cable delivers both 12Gb/s SAS 3.0 signal and drive power without extra SATA power cords.

Should I choose the 12Gb/s SAS 3.0 version or a slower cable for my 6Gb/s SAS and SATA drives?

The cable runs at 12Gb/s per channel and is backward compatible with 6Gb/s and 3Gb/s SAS and SATA drives, so one cable covers all three speed generations.

What does the 12Gb/s SAS 3.0 rating mean when the cable is installed in a live server running 24hour workloads?

The shielded 1meter design with tinned copper conductors maintains stable 12Gb/s throughput per channel under continuous heavy load while suppressing electromagnetic interference and crosstalk.
