Product Identity

The Dell ConnectX-4 924JW is a 50GbE QSFP28 OCP 2.0 mezzanine network card built for Dell PowerEdge servers such as the R740, R740xd and R940. It provides high-speed Ethernet connectivity for data-intensive enterprise workloads.

Deciding Specification

The card uses an OCP 2.0 mezzanine interface with a QSFP28 port delivering 50GbE throughput. It fits only Dell PowerEdge systems that support the OCP 2.0 form factor, so buyers must verify slot compatibility before purchase.

Thermals, Noise and Power

As a mezzanine card it relies on the server's internal airflow and cooling design. Power draw and acoustic profile are determined by the host chassis and workload, not by a dedicated fan on the card itself.

Questions about this item

What does 50GbE mean when the card is installed in a PowerEdge server?

The card provides up to 50 gigabits per second of Ethernet bandwidth for data-intensive workloads such as virtualization, cloud computing and HPC.

How does the OCP 2.0 mezzanine interface limit the connection in practice?

It plugs directly into the server's OCP 2.0 mezzanine slot, so the link speed is capped at the 50GbE rating of the card itself.

What physical slot and server models accept this mezzanine card?

It fits the OCP 2.0 mezzanine slot in Dell PowerEdge servers such as the R740, R740xd and R940.
