Short .5m fanout cable with SFF8643 plug splitting to two SFF8639 connectors plus SATA 15pin power, 32AWG copper wire

SMUGDESK

SMUGDESK .5m Mini SAS HD 8643 4i to Dual SAS 8639 Cable with SATA 15Pin Power 12Gbps 32AWG

SKU CH-243G-2KEAB

Connects a Mini SAS HD 8643 host port to dual SAS 8639 drives with integrated SATA 15pin power, delivering 12Gbps bandwidth over 32AWG copper

  • Converts one Mini SAS HD port to dual SAS 8639 drive ports for storage expansion
  • Delivers 12Gbps SAS 3.0 bandwidth for U.2 NVMe SSDs and SAS hard drives
  • Integrated SATA 15pin power line supplies drives directly to simplify server wiring
  • Premium 32AWG pure copper wire reduces signal loss and crosstalk for reliable performance
  • Compact .5m length allows tidy shortrange routing inside 2U and 4U rackmount servers

Server Storage Expansion Cable

The SMUGDESK .5m fanout cable converts a single Mini SAS HD SFF8643 4i host port into two SFF8639 U.2 or SAS drive connectors. Integrated SATA 15pin power lines supply both drives directly from the cable. Built with 32AWG copper wire, it supports 12Gbps SAS 3.0 bandwidth for highdensity storage arrays.

For MultiDrive RAID Builders

This cable suits administrators adding dual U.2 NVMe SSDs or enterprise SAS hard drives to a RAID controller or backplane with limited ports. The short .5m length fits tidy routing inside 2U or 4U rackmount chassis. Builders needing longer runs for fulltower cases or external JBOD enclosures should look elsewhere.

12Gbps SAS 3.0 Throughput

The decisive specification is the certified 12Gbps SAS 3.0 data rate across both SFF8639 branches. It guarantees full bandwidth for modern U.2 NVMe SSDs and highspeed SAS hard drives without bottlenecks. If the host controller or drives operate only at 6Gbps the cable will still function but the extra headroom goes unused.

Questions about this item

Which length should I pick for a 2U server backplane?

The .5m length is designed for short internal routing inside 2U and 4U rackmount servers, keeping cable runs tidy without excess slack.

What does the 12Gbps rating mean when the cable is installed?

It supports SAS 3.0 at 12Gbps, giving each attached U.2 NVMe SSD or SAS drive full 12Gbps bandwidth from the single SFF8643 4i host port.

How does the SFF8643 to dual SFF8639 interface work with power?

The fanout splits one SFF8643 4i Mini SAS HD port into two SFF8639 drive connectors and includes a SATA 15pin power lead to supply both drives directly.
