SMUGDESK SFF8644 to QSFP SFF8436 SAS Cable .5m 12Gbps 28AWG 10ohm Black

SKU CH-9BM0-EYKH3

Connects MiniSAS HD SFF8644 to QSFP SFF8436 at 12Gbps for server stacking

  • SFF8644 to QSFP SFF8436 cross-interface conversion enables server stacking
  • 12Gbps high-bandwidth transmission ensures stable enterprise-grade data communication
  • 28AWG pure copper with 10ohm impedance matching minimizes signal loss
  • .5m compact length optimizes neat internal stacking wiring for server racks
  • Durable black jacketed design suits storage arrays and high-density server setups

Cross-interface SAS cable

The SMUGDESK SFF8644 to QSFP SFF8436 cable converts MiniSAS HD to QSFP for internal server stacking connections. It targets system builders linking storage arrays or expanding high-density server racks. The half-metre length keeps internal wiring tidy in tight chassis spaces. Buyers needing longer runs or different connector types should look elsewhere.

Signal integrity and build

Pure copper 28AWG conductors maintain a strict 10ohm impedance to minimise crosstalk and attenuation. The black jacket adds mechanical protection for continuous operation inside racks. No active components mean silent, passive operation with no extra power draw.

12Gbps SAS bandwidth

Rated at 12Gbps, the cable supports enterprise-grade SAS throughput for storage expansion and inter-device communication. The SFF8644-to-SFF8436 pinout determines compatibility with specific controllers and backplanes. Verify both ends match your hardware before purchase.

Questions about this item

How do I connect the SFF8644 MiniSAS HD end to the QSFP SFF8436 port without bending the 28AWG cable?

Align the MiniSAS HD SFF8644 connector with the controller port, then insert the QSFP SFF8436 end straight into the server stacking slot; the 0.5m length leaves no slack, so route it before locking both latches.

Will the 10ohm impedance on the 28AWG copper degrade and need recrimping?

The 28AWG pure copper conductors and fixed 10ohm impedance are factory terminated; no field recrimping is possible — replace the entire cable if signal errors appear.

At what point does the 12Gbps link become the bottleneck during sustained server stacking traffic?

The 12Gbps SAS bandwidth limit is reached first; sustained writes across the 0.5m link will saturate at that rate before the 40G QSFP interface or 10ohm cable loss becomes a factor.
