40G QSFP+ to Mini SAS HD Cable

This 100cm direct-attach cable connects a QSFP+ 40Gbps port to a Mini SAS HD SFF-8644 interface. It is built for network engineers linking switches, routers, firewalls or network cards in data-centre racks. The assembly complies with the SFF-8436 specification for reliable 40 gigabit signalling.

Male-to-female plug-and-play

The 38-contact male QSFP+ end inserts into the transceiver cage while the female Mini SAS HD end mates with the target device. No drivers or configuration are required. Misalignment during insertion can bend the high-density pins, so guide the connectors straight in without forcing the latch.

40Gbps headroom for short reach

The copper DAC construction delivers full 40Gbps throughput across the 100cm span with minimal latency. Signal integrity degrades beyond the specified length, so longer runs need active optical cables instead. The shielding resists EMI in dense cabinets, but the cable cannot convert between SAS and Ethernet protocols.

Questions about this item

How can I verify the 40 Gbps QSFP+ to Mini SAS HD SFF-8644 link is operating correctly after installation?

Check the switch or HBA port LEDs for a solid link light at 40 Gbps, then run a SAS diagnostic or storage benchmark to confirm error-free throughput across the 100 cm cable.

What comes in the box and what must I source separately?

The box contains the Vszerda QSFP+ 40G to Mini SAS HD SFF-8644 DAC cable itself; you must provide compatible QSFP+ and Mini SAS HD SFF-8644 ports on your switches, routers, firewalls or network cards.

Which version should I choose for a 1-metre run between Cisco, Huawei or H3C gear?

Select the 100 cm (3.3 ft) model that complies with SFF-8436 and matches the 38-connector, male-to-female pinout listed for your Cisco, Huawei, H3C, TP-LINK, ZTE or RIGOAL equipment.
