Dell PowerEdge R940 NVMe Expander Cable

This cable connects the A2/B2 backplane to the PCIe subsystem inside a Dell PowerEdge R940 server. It enables full NVMe integration across 24 drive bays for 2.5-inch storage devices. The part is built for continuous datacenter workloads where consistent high-bandwidth routing is required.

Supports 24× 2.5" NVMe backplane

The cable is specifically designed to support 24× 2.5-inch NVMe-enabled backplane slots A2 and B2. This single compatibility requirement determines whether the part fits your server configuration. It will not function with other backplane layouts or server models.

Clean routing for improved airflow

The cable's design provides clean internal routing that helps maintain airflow within the chassis. No additional accessories or software are included with this replacement part. The physical cable itself delivers the connectivity needed for scalable NVMe storage arrays.

Questions about this item

What does the 24 NVMe drive support mean for a PowerEdge R940?

It allows the A2/B2 backplane to connect up to 24 2.5-inch NVMe drives directly to the PCIe subsystem for full bandwidth.

Which interface standard does the expander cable use and what does it limit?

The cable carries PCIe signals from the backplane to the NVMe expander, so drive speed is limited by the PCIe generation of the R940 slot.

What physical space and mounting does the cable require inside the R940?

It routes between the A2/B2 backplane and the NVMe expander card, using the server's existing cable channels and connectors.
