QNAP CAB-SAS10M-8644 1.0M Mini-SAS 12G Expansion Cable
Overview
The CAB-SAS10M-8644 is a 1.0-meter Mini-SAS 12G cable terminated with an SFF-8644 connector on each end. It is the purpose-built link between QNAP NAS enclosures and QNAP SAS expansion units — replacing this cable with a generic alternative risks signal integrity at 12Gbps line rates, so using the matched QNAP cable matters in high-throughput storage deployments. At 1.0 meter, it fits standard rack bay-to-bay runs where the NAS and its expansion shelf occupy adjacent or nearby rack units.
Compatibility
The CAB-SAS10M-8644 is verified compatible with the following QNAP hardware:
- REXP-1220U-RP — 12-bay 2U rackmount SAS expansion enclosure
- REXP-1620U-RP — 16-bay 2U rackmount SAS expansion enclosure
- SAS-12G2E-D — dual-port 12Gbps SAS expansion card
- SAS-12G2E-U — single-port 12Gbps SAS expansion card
Note: The closely related CAB-SAS10M-8644-8088 variant uses an SFF-8088 connector on one end and targets a different set of hosts — specifically the SAS-12G2E (non-suffix), ES1640dc v2, and EJ1600. Confirm your host HBA or expansion card connector type before ordering; the SFF-8644 and SFF-8088 connectors are physically incompatible.
