SMUGDESK Mini Slimline SAS Cable

This SMUGDESK cable connects a Mini Slimline SAS SFF8654 4i 38Pin host port to a U.2 SFF8639 device while delivering power through a SATA 15pin male connector. It is built for enterprise server storage upgrades and highdensity internal wiring. The 39.37inch length supports flexible routing inside server chassis.

Server storage installers needing 24Gbps U.2 links

Installers expanding U.2 SSD storage with a Mini Slimline SAS host interface will find the required data and power connections in one assembly. The 32AWG pure copper conductors and shielding maintain signal integrity at 24Gbps. Builders whose host side uses a different connector cannot use this cable.

SFF8654 4i 38Pin host interface

The single specification that determines fit is the SFF8654 4i 38Pin host connector; the cable only works with controllers or backplanes presenting that exact interface. The U.2 SFF8639 device end and SATA 15pin power tail are fixed. Verify the host port matches before purchasing.

Questions about this item

How do I connect the SFF8654 38pin end and the SATA 15pin power plug during installation?

Plug the SFF8654 4i 38pin connector into the motherboard or controller Mini Slimline SAS port, attach the SFF8639 U.2 end to the SSD, then seat the SATA 15pin male power connector into a free SATA power cable from the PSU.

What upkeep does the 32AWG pure copper cable with shielding require over time?

Inspect the connectors and shielding for dust or bent pins during routine server maintenance; reseat the SFF8654 and SFF8639 ends if intermittent errors appear, but no scheduled replacement is needed for the cable itself.

At what point does the 24Gbps link become the bottleneck under heavy sustained I/O?

The 24Gbps ceiling is reached when the U.2 SSD or RAID controller saturates the four-lane SFF8654 4i interface; beyond that, queue depth and controller firmware determine actual throughput.
