Connectors and form factor

The Vszerda SlimSAS cable links an SFF-8654 38-pin connector to an SFF-8643 36-pin connector using a male-to-female orientation. Four channels carry data at 24 Gbps for SAS and 8 GT/s for PCIe per channel. The 80 cm black cable meets SAS 3.0 and Ultraport SlimSAS specifications. Its smaller connector profile saves space inside dense server chassis.

Replaces wider Mini SAS HD cabling

Builders moving from bulkier SFF-8643 assemblies gain the same four-channel bandwidth in a slimmer cable that routes more easily through tight backplanes. The upgrade is worth it when chassis clearance limits standard Mini SAS HD bend radius or when port density demands the narrower SFF-8654 footprint. Existing SFF-8643 ports remain compatible through the 36-pin end.

Sustained throughput in server backplanes

Shielded construction supports continuous 24 Gbps SAS traffic across all four lanes without signal degradation during extended rebuilds or heavy database scans. The cable maintains link stability at the rated speed over the full 80 cm length under typical server thermal conditions. It is not suited for external runs or environments requiring ruggedised jacketing.

Questions about this item

What clearance does the SFF-8654 38-pin connector need?

The SlimSAS 4i connector is smaller than legacy Mini SAS HD plugs, so it fits in tight backplanes and dense drive cages without blocking adjacent slots.

How do I seat the SFF-8643 36-pin end without damaging the latch?

Align the keyed Male-to-Female interface, push straight in until the metal latch clicks, then pull gently to verify; forcing it at an angle bends the 36-pin header.

When should I replace this 80 cm cable in a 24 Gbps SAS link?

Swap it if you see intermittent drive drops, CRC errors in controller logs, or physical kinks near the 38-pin or 36-pin ends after repeated chassis swaps.
