Host cable for SAS controllers

This SFF-8643 to four SATA breakout cable connects a Mini SAS HD host port on a motherboard or RAID controller to up to four SATA hard drives. The 10-pin SFF-8643 plug is the host side; each labelled SATA connector is a target for a drive. It is built for internal storage expansion in servers or workstations using SAS infrastructure.

Practical limits of the SAS interface

Data transfer speed depends on the capabilities of the SAS controller and the attached SATA drives, not on the cable itself. The SFF-8643 connector supports a transition from 6Gb to 15Gb signalling, but actual throughput is set by the controller and drive combination. This cable will not work if the SFF-8643 port is on a backplane rather than a host controller, and it is not a reversed cable with SATA as the host.

Build quality and daily implications

UL-listed 12Gb raw SAS cable stock is used for the assembly, and locking connector latches on the SFF-8643 end provide a stable connection. Each of the four SATA breakouts is labelled to simplify cable management during installation or maintenance. The 3.3 ft length suits typical chassis routing between a controller card and drive bays.

Questions about this item

Should I choose the 3.3 ft SFF-8643 to 4x SATA cable or a different length for my server chassis?

The 3.3 ft length suits most standard server and workstation chassis; verify the routing distance from your SFF-8643 controller port to the drive bays before ordering.

What real-world throughput will I see with this 12Gb raw SAS cable connected to SATA III drives?

Throughput is capped by the SATA III drives at 6 Gb/s per lane, so the 12Gb cable headroom ensures reliable signalling but does not exceed the drive limit.

How does the SFF-8643 interface differ from SFF-8646 and what does that mean for my RAID controller?

SFF-8643 is a host-side Mini SAS HD connector for controllers; SFF-8646 is a target-side backplane connector, so this cable only works when the SFF-8643 port is on your RAID controller or motherboard.
