SFF-8643 breakout cable to four 29-pin SFF-8482 SAS connectors

SMUGDESK

SMUGDESK SFF-8643 to 4×SFF-8482 12Gbps SAS Cable

SKU CH-EMD9-DFGJV

Breakout cable converts one SFF-8643 Mini SAS HD port into four 29-pin SFF-8482 connectors for 12Gbps SAS 3.0 multidrive server expansion

  • Converts one SFF8643 host port to four SFF8482 drive ports
  • 12Gbps SAS 3.0 speed supports enterprise HDDs and SSDs
  • Low signal loss harness keeps multidrive arrays stable
  • Server-grade build withstands continuous rackmount operation
  • Plug-and-play design works with HD1 adapters and RAID controllers

1-to-4 SAS Breakout Cable

This cable converts a single SFF-8643 Mini SAS HD host port into four SFF-8482 29-pin connectors for SAS or SATA hard drives. It targets administrators expanding enterprise RAID arrays, NAS systems, or high-density storage backplanes.

Sustained 12 Gbps Transfer

The harness is built to maintain 12 Gbps SAS 3.0 signalling across all four lanes during continuous multi-drive workloads. Optimised wire routing preserves signal integrity so that enterprise-grade HDDs and SSDs keep throughput stable under load.

Server-Grade Construction

Durable materials and strain relief suit non-stop operation in rackmount servers and storage enclosures. The plug-and-play breakout design simplifies cable management when connecting HD1 adapters or RAID controllers to multiple drive bays.

Questions about this item

Does the SFF-8643 breakout cable generate noticeable heat or draw extra power when running all day in a server?

The cable is a passive copper assembly, so it adds no active heat or power draw beyond the negligible resistance of the conductors during continuous 12 Gbps operation.

What host-side connector must my controller already have for this 4×SFF-8482 breakout to plug in?

Your RAID controller or HBA needs a single SFF-8643 Mini SAS HD port to accept the host end of the cable.

Will the four SFF-8482 29-pin connectors work with the older SAS 2.0 drives I still use in my array?

Yes, the 12 Gbps SAS 3.0 link is backward compatible, so each 29-pin port will negotiate down to 6 Gbps with legacy SAS or SATA drives.
