SMUGDESK SFF8644 to QSFP SFF8436 SAS cable 28AWG 12Gbps 2m black

Server stacking cable

This SMUGDESK hybrid cable connects MiniSAS HD SFF8644 ports to QSFP 40G SFF8436 ports for server stacking and storage interconnection. It is built for enterprise SAS environments that require a direct link between RAID controllers, storage arrays or multi-server clusters. The 28AWG low-loss copper conductors and 10ohm impedance matching maintain steady 12Gbps signal integrity over the full run. The 2meter black shielded jacket suits dense rackmount installations.

Port and protocol check

Verify that both endpoints present the exact SFF8644 and SFF8436 interfaces before ordering. The link operates at 12Gbps SAS speeds, so the host controller and target device must support this rate for full performance. Confirm the 2meter reach fits your internal routing path without excessive tension or sharp bends. This cable does not convert to other connector families or signalling standards.

Thermals noise and power

Passive copper construction adds no active cooling requirement and produces zero acoustic noise in operation. Power draw is limited to the signalling current supplied by the connected ports, with no external supply needed. The shielded jacket helps contain electromagnetic interference in high-density racks, keeping signal quality stable under sustained 12Gbps loads. Thermal impact on adjacent components is negligible.
