Vszerda QSFP to SFF-8644 SAS Cable

This new Vszerda cable connects QSFP+ (SFF-8436) ports to SFF-8644 Mini SAS ports using passive copper construction. It measures 6.6 ft in length with male-to-male connectors and 30AWG wire rated at 100 Ohms impedance. The assembly supports up to 10 Gbps per channel and complies with QSFP MSA and SAS 3.0 specifications for use with NetApp DS4243, DS4246 and DS2246 systems.

Who This Suits and Who It Does Not

Installers linking QSFP+ equipped switches or controllers to SFF-8644 storage shelves will find the correct pinout and length here. The passive design suits short rack runs where low power draw is preferred. Buyers needing active optical reach for longer distances, different connector combinations such as SFF-8644 to SFF-8644, or speeds beyond 10 Gbps per channel must choose another cable type.

Deciding Specification — Connector Pair and Speed

The defining detail is the hybrid SFF-8436 to SFF-8644 interface running at 10 Gbps per channel over passive copper. This exact connector pairing and signal rate determine whether the cable matches the ports on both ends of the link. Verify both port types before ordering.

Questions about this item

What type of QSFP+ port must my device have to accept the SFF-8436 connector on this cable?

The SFF-8436 end plugs into any standard QSFP+ cage, so the host or switch must provide a QSFP+ receptacle.

Will the SFF-8644 end connect to the Mini SAS HD ports on my NetApp DS4243, DS4246 or DS2246 shelf?

Yes, the SFF-8644 connector matches the Mini SAS HD interface used on those NetApp disk shelves.

How can I confirm the link is running at the rated 10 Gbps per channel after I connect the cable?

Check the port statistics on both the QSFP+ side and the SFF-8644 side; they should report a 10 Gbps SAS 3.0 link with no errors.
