SFF-8644 to SFF-8087 server cable

This 12Gbps adapter cable connects Mini SAS HD SFF-8644 ports to legacy Mini SAS 36-pin SFF-8087 connectors. It is built for server and storage arrays that need to link newer controllers or backplanes with older drive enclosures. The 1 metre copper assembly supports SAS traffic at full 12Gbps line rate.

Electrical and thermal ratings

The cable is rated for 30V AC working voltage and 300V DC withstand for 0.1 second. Insulation resistance measures at least 500M ohms while on-resistance stays at 5 milliohms maximum. Contact current is specified at 0.5A with low-power contact impedance of 80M ohms max. Operating temperature spans -20 to 85 Celsius.

Build integration notes

Weighing 150g, the black cable adds minimal mass inside a chassis and requires no external power. It frees up PCIe slots by allowing direct backplane-to-controller links instead of extra HBAs. The 55.5N maximum insertion force means firm seating without damaging dense backplane ports. Buyers needing longer runs or different connector keying should verify pin-out compatibility before ordering.

Questions about this item

How do I connect the SFF-8644 end to my backplane without damaging the pins?

Align the SFF-8644 connector key with the backplane receptacle, then press straight in until the latch clicks; the insertion force limit is 55.5N, so avoid angling the plug which bends the high-density pins.

When should I replace this cable if the contact resistance rises?

Replace the cable once the on-resistance exceeds 5 ohms per contact or the low-power contact impedance goes above 80 megohms, as higher resistance degrades the 12 Gbps signal integrity.

What temperature limit will throttle sustained 12 Gbps transfers first?

The cable is rated for -20 to 85 °C; operating near 85 °C increases conductor resistance and can cause the link to drop below 12 Gbps before any other limit is reached.
