NetApp DS4243 DS4246 DS2246 compatibility

This cable connects NetApp DS4243, DS4246 and DS2246 storage shelves to host adapters using a QSFP+ (SFF-8436) to SFF-8644 interface. It suits administrators who need a direct copper link between those specific shelf models and compatible QSFP+ ports. The 3.3-foot length fits typical rack spacing without excess slack. It is not for buyers who need longer runs or different shelf connectors.

QSFP MSA and SAS3.0 compliance

The cable meets the QSFP Multi-Source Agreement and the SAS3.0 specification, ensuring interoperability with open-standard QSFP+ equipment from vendors such as Cisco, Ubiquiti, Netgear and others listed. Each channel supports up to 10 Gbps transfer rate with low power consumption because the assembly is passive copper. Precision process control minimises pair-to-pair skew for reliable signal integrity.

30AWG 100-ohm passive copper construction

The 30AWG conductors present a 100-ohm impedance across 38 pins in a male-to-male configuration. Passive design means no external power is required, reducing heat and failure points in the rack. The fixed 3.3-foot reach determines placement of the shelf relative to the host; longer distances would require an active or optical alternative not provided here.

Questions about this item

Does the 30 AWG copper construction on the QSFP+ (SFF-8436) to SFF-8644 cable require any periodic replacement?

No, the passive 30 AWG copper cable has no active components or moving parts that wear out, so it does not need scheduled replacement under normal use.

What is the maximum sustained data rate per channel before the 100-ohm impedance limit is reached?

Each channel supports up to 10 Gbps, and the 100-ohm impedance is maintained across the full 3.3 ft length at that rate.

How much heat or noise does the passive copper cable generate when running at 10 Gbps all day?

The cable is completely passive with no power draw, so it produces zero noise and negligible heat even during continuous 10 Gbps operation.
