Server Stacking Link
This 1 metre cable bridges MiniSAS HD SFF8644 and QSFP 40G SFF8436 ports for server stacking, RAID controller attachment and JBOD expansion. It targets administrators building high density storage fabrics or aggregating compute nodes in enterprise racks where 12Gbps SAS 3.0 throughput is required.
Signal Integrity
Twenty eight AWG copper conductors with controlled ten ohm impedance preserve signal quality across the link while supporting 12Gbps data rates. The shielded black jacket reduces crosstalk and electromagnetic interference in densely populated chassis without adding bulk that would restrict airflow.
Rack Routing Flexibility
The one metre reach allows tidy routing between adjacent rack units, between a controller and a shelf or across a short intra rack gap. Both connectors use industry standard latch mechanisms so the link stays secure during vibration or hot swap maintenance in production environments.

Questions about this item
How do I connect the SFF8644 end to the QSFP 40G SFF8436 port, and which step do installers often miss?
Align the MiniSAS HD SFF8644 connector with the controller port and the QSFP 40G SFF8436 end with the switch or storage port, then press both straight in until each latch clicks; the step often missed is verifying both latches are fully seated before routing the cable.
What maintenance or replacement will this 28AWG copper cable need over time?
No scheduled maintenance is required; inspect the 10ohm impedance-controlled conductors and shielding during rack audits and replace the cable only if physical damage or signal errors appear on the 12Gbps SAS 3.0 link.
What limit appears first when the link runs at 12Gbps continuously?
The 28AWG copper construction and 10ohm impedance matching set the practical ceiling; sustained 12Gbps throughput is supported, but signal integrity degrades if the cable is bent tighter than the shield allows or if connector latches loosen under vibration.
