QSFP+ SFF-8436 to SFF-8644 SAS Cable .5m

This passive copper cable connects QSFP+ (SFF-8436) ports to Mini SAS HD (SFF-8644) ports at up to 10 Gbps per channel. It targets administrators linking switches or HBAs to NetApp DS4243, DS4246 or DS2246 shelves in dense racks where a half-metre reach is sufficient.

Replaces longer or active DAC assemblies

The .5m length removes slack that blocks airflow in 1U or blade chassis, while the 30AWG 100-Ohm construction meets SAS3.0 and QSFP MSA specs without external power. The jump is worth it when port density forces short runs and latency budgets rule out active optics.

Sustained 10 Gbps per channel under load

Precision pair-to-pair skew control keeps eye diagrams open during continuous back-to-back frame streams typical of storage replication or high-frequency trading feeds. Low power draw means no thermal throttling even when all 38 contacts carry traffic for hours in poorly ventilated enclosures.

Questions about this item

What connectors and length does this .5 m cable use?

It has a QSFP+ (SFF-8436) plug on one end and an SFF-8644 Mini SAS plug on the other, both male, and the cable is 0.5 m (1.64 ft) long.

How do I plug it in without damaging the latch?

Align each connector with its port, push straight in until the metal latch clicks, and pull the release tab — not the cable — when removing it.

When should I replace this 30 AWG copper passive cable?

Replace it if the latch breaks, the jacket is kinked or cut, or you see intermittent link errors at 10 Gbps.
