Internal SAS fan-out cable

This 0.5 metre cable connects a single SFF-8643 host port on a SAS controller or motherboard to four SFF-8482 drives. Each 29-pin connector includes a 15-pin power segment so power and data reach the drive from one cable. It supports 12 Gbps SAS and SATA signalling for internal storage arrays.

Build integration

The fan-out design frees up controller ports by consolidating four drive links into one SFF-8643 connection. 30 AWG conductors keep the cable flexible for routing inside dense chassis or rack-mount servers. Verify that the SFF-8643 side attaches to a controller, not a backplane, otherwise the cable will not function.

Upgrade context

The cable replaces four separate data-plus-power assemblies with a single loom, reducing clutter and connection points. The jump is worthwhile when a controller has limited SFF-8643 ports but the build needs four SAS or SATA drives. It does not suit setups where the SFF-8643 interface resides on a backplane rather than a controller.

Questions about this item

What is the maximum data rate the SFF-8643 end can sustain?

The cable is rated for 12 Gbps transmission, matching SAS-3 controller and drive links.

How much heat or noise does the cable add when the drives run continuously?

The passive 30 AWG assembly adds no active heat or noise; only the drives and controller generate measurable warmth.

Which controller connector must the system already have for this cable to work?

The host side requires a Mini SAS SFF-8643 port on a RAID controller or motherboard; backplane SFF-8643 ports are not compatible.
