Vszerda SFF-8643 to SFF-8643 12G Internal Mini SAS HD Cable 1m

SFF-8643 Internal Mini SAS HD Cable

The Vszerda SFF-8643 to SFF-8643 cable is a 1 metre internal Mini SAS HD assembly rated for 12 Gb/s data transfer. It carries 32 conductors in a male-to-male configuration and includes sideband signaling for enclosure management and expander zoning. The compact design suits high-density server and storage chassis where PCB space is limited. It connects NVMe backplanes, RAID controllers or SAS expanders with matching SFF-8643 ports.

Suits builds with SFF-8643 ports.

This cable fits systems that expose SFF-8643 Mini SAS HD interfaces on both ends. It will not work with equipment that uses different internal connector types, so builders whose backplanes or controller cards require another interface must select a different assembly. The 100-ohm impedance and sideband support address advanced SAS features, but only when the host and device both present SFF-8643 sockets.

12 Gb/s speed rating decides fit

The single specification that determines whether this is the correct part is the 12 Gb/s signalling rate. If the controller, expander or backplane operates at 6 Gb/s the cable will still function, but a 12 Gb/s link is required to utilise the full bandwidth of SAS 3.0 devices. Verify that both endpoints support 12 Gb/s before purchasing.
