SKU CH-JYRP-STSAM

Connects a Mini SAS SFF-8643 controller to four SFF-8482 drives with 15-pin power ports

  • Connects one SFF-8643 controller to four SFF-8482 drives
  • 29-pin connectors with integrated 15-pin power ports
  • 5 m length suits compact server chassis
  • 6 ft cable reaches nearby backplane bays
  • Controller-to-target wiring prevents backplane misconnection

Cable purpose and fit

This internal cable connects a Mini SAS SFF-8643 host controller to four SFF-8482 drives using a 0.5 metre fan-out design. It is built for servers or workstations that need to break out a single x4 controller port into four individual x1 drive links. The assembly includes a 15 pin power port on each drive leg. Buyers whose Mini SAS port sits on a backplane rather than a controller cannot use this cable.

Thermals noise and power

The cable is a passive copper assembly so it adds no active cooling requirement and generates no audible noise. Power for the attached drives is supplied through the integrated 15 pin connectors, drawing from the host system's power distribution. No external power adapter or additional cabling is needed for the drive-side power pins.

What the accessories change

Each of the four drive legs terminates in a 29 pin SFF-8482 connector that carries both data and the 15 pin power interface in one plug. This reduces the number of separate cables inside the chassis compared to using distinct data and power leads. The fixed 0.5 metre length limits routing options to short runs between a controller card and nearby drive bays.

Questions about this item

How do I install the SFF-8643 end so the controller detects all four drives?

Plug the SFF-8643 connector into the SAS controller or motherboard port labelled Mini SAS host; the four SFF-8482 ends then attach to the drives. The cable will not work if the SFF-8643 port is on a backplane instead of the controller.

What upkeep does the 15-pin power port on each SFF-8482 connector need?

No routine maintenance is required for the 15-pin power port; simply ensure the connector stays fully seated and free of dust. If a pin bends or the latch breaks, replace the entire cable assembly.

At what point does the 0.5 m length become a limit during sustained transfers?

The 0.5 m length meets SAS signal-integrity specs, so the first limit under sustained use is usually the controller or drive throughput, not the cable itself.
