Vszerda SFF-8643 SAS Cable for Servers

This 1-metre internal cable connects Mini SAS HD SFF-8643 ports on RAID controllers or PCIe host bus adapters. It carries up to four lanes of SAS data at 12 Gbps and is backward compatible with SAS 2.1 at 6 Gbps. The assembly targets server builders and storage administrators wiring direct-attached storage or JBOD enclosures. Buyers needing longer runs or external Mini SAS HD connectors should look elsewhere.

Passive 30 AWG Construction with 100 Ohm Impedance

The cable uses 30 AWG conductors and controlled 100 Ohm differential impedance to maintain signal integrity at 12 Gbps without active equalisation. No power draw or cooling is required, so the link adds zero thermal load inside a chassis. Shielded twisted pairs suppress crosstalk in dense backplane environments. Installers should verify bend-radius limits for their specific enclosure.

Male-to-Male 36-Pin Connectors Ready for Immediate

Each end presents a male 36-pin SFF-8643 plug that mates directly with compatible RAID cards such as Dell PERC H200, H310 or H700 and Norco RPC-4220 or RPC-4224 backplanes. The package includes one cable only; no mounting brackets, drive trays or management software are supplied. Cable management clips or ties must be sourced separately.

Questions about this item

How do I connect the SFF-8643 cable to my RAID controller and what is the common mistake?

Plug each 36-pin male end straight into the Mini SAS HD ports on the controller and backplane; the frequent error is forcing the latch at an angle, which bends the internal pins.

What upkeep will this 12 Gbps SAS cable require over time?

No scheduled maintenance is needed; inspect the connectors for dust or bent pins during hardware changes and replace the cable only if link errors appear.

At what point does signal integrity become the limiting factor during sustained 12 Gbps transfers?

The 1-metre AWG30 construction meets the 100-ohm impedance target, so the practical limit is the controller or backplane budget rather than the cable itself.
