Mini SAS HD SFF8643 4i to dual SFF8639 with SATA 15pin power cable .5m

SMUGDESK

SMUGDESK Mini SAS HD SFF8643 4i to Dual SFF8639 with SATA 15Pin Power Cable 12Gbps .5m

SKU CH-86VH-0SXH8

Connects one SFF8643 port to two SFF8639 U.2 drives with integrated SATA 15pin power, delivering 12Gbps SAS speed over 32AWG pure copper in a compact .5m length

  • Connects two U.2 SSDs from one SFF8643 port with integrated SATA 15pin power
  • Delivers 12Gbps SAS data throughput for highspeed server storage performance
  • Pure copper 32AWG conductors with shielding provide stable signal and antiinterference capability
  • Short .5m length simplifies internal wiring in compact server chassis
  • Compatible with Supermicro Dell HPE Lenovo enterprise server systems

SFF8643 4i to dual SFF8639 cable

This cable adapts a single Mini SAS HD SFF8643 4i port to two SFF8639 connectors for dual U.2 SSD attachment. It includes an integrated SATA 15pin power feed so both drives receive power through the same assembly. The 0.5m length suits dense server chassis where space is limited.

12Gbps SAS bandwidth and 32AWG copper limits

The link operates at 12Gbps SAS speed, so total throughput is shared between the two connected drives. 32AWG pure copper conductors keep signal loss low over the short run, but the thin gauge restricts use to internal rackmount enclosures. External or long-run deployments would exceed the practical reach of this cable.

Replaces separate data and power looms

It consolidates a Mini SAS HD data cable plus two discrete SATA power leads into one harness, reducing clutter in 2U or 1U nodes. The upgrade is worthwhile when a backplane or HBA offers a free SFF8643 4i port and two U.2 bays need simultaneous power and data. Builders needing more than two drives per port or a longer cable run should look elsewhere.

Questions about this item

Should I choose the .5m length or a longer cable for my server?

The .5m length is designed for compact server chassis and tight internal routing; choose a longer cable only if the drive bays sit farther from the backplane.

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

It allows each U.2 SSD to run at full SAS 12Gbps speed, so the dual-drive link can sustain high-throughput storage workloads without cable bottlenecks.

How does the SFF8643 4i interface work with the dual SFF8639 connectors?

One SFF8643 4i port splits into two SFF8639 connectors, letting a single controller port drive two U.2 SSDs while the SATA 15pin supplies power to both drives.
