SlimSAS SFF-8654 8i to dual SFF-8643 cable, silver-plated 32AWG, .5-.8m

Enfain

Enfain SFF86548i-28643 SFF-8654 8i to 2x SFF-8643 infiniband cable .5-.8m

SKU CH-SJMB-3E0SJ MPN SFF86548i-28643

Connects a 74-pin SFF-8654 8i host to two 36-pin SFF-8643 targets using 32AWG silver-plated copper at 85-ohm impedance for SAS 4.0 links up to 600 Mbps

  • SlimSAS 4.0 host connector fits dense server racks
  • Dual SFF-8643 targets split one port to two drives
  • Silver-plated 32AWG copper keeps 85-ohm impedance stable
  • VW-1 rated jacket meets fire-safety requirements
  • 5 to 0.8 metre length suits short-run cabling

Connection layout

This cable links a single SFF-8654 8i host port to two SFF-8643 target ports. The 74-pin male connector plugs into a SlimSAS 4.0 controller while the dual 36-pin female sockets attach to backplanes or enclosures. It suits builders wiring high-density storage arrays inside servers or rack cabinets.

SAS-4.0 bandwidth

Rated for the SAS-4.0 standard, the assembly supports a 600 Mbps/s signalling rate over 32 AWG silver-plated oxygen-free copper. Aluminium-foil shielding and an 85-ohm impedance target protect signal integrity across the link. Choose this part when the controller and backplane both require SAS-4.0 speeds.

Thermals and power

Passive copper construction means no active cooling, no fan noise and no extra power draw beyond the signalling current. The VW-1 rated jacket and RoHS-compliant materials meet typical data-centre fire and substance restrictions. Length options of .5 to .8 metres keep routing tidy without adding measurable latency.

Questions about this item

What throughput can I expect when this 600 Mbps/s cable is installed in a server?

The cable is rated for 600 Mbps/s; actual throughput depends on the controller, drives and protocol negotiated on the link.

Which SAS generation does the SFF-8654 8i connector support and what speed ceiling does that impose?

The connector complies with SAS-4, so the link will negotiate up to the SAS-4 signalling rate supported by the attached devices.

How much clearance do the 74-pin and dual 36-pin connectors need to seat properly?

The Ultraport SlimSAS form factor occupies the same space as Mini-SAS, so standard backplane cut-outs accept both ends.
