DELL CDC7W PCI Express Gen 3.0 x4 NVMe Expander Card

SKU CH-J71S-62DJ2

Adds four PCI Express 3.0 lanes to a PowerEdge R730XD for NVMe storage expansion

  • InterfacePCI-Express
  • Adds NVMe capacity to PowerEdge R730XD servers
  • PCI Express Gen 3.0 x4 interface for fast data paths
  • Expands storage without replacing the backplane
  • Dell-engineered expander card for native compatibility
  • Controller design built for high-performance computing workloads

Dell CDC7W NVMe Expander Card

The Dell CDC7W is a PCI Express Gen 3.0 x4 NVMe expander card designed for the PowerEdge R730XD server. It adds extra NVMe drive slots to the system, allowing administrators to scale high-speed storage capacity inside the chassis.

Compatibility check

Verify that the server has an available PCI Express x4 slot and that the BIOS and firmware revisions support NVMe expander cards. Confirm the chassis backplane and cabling can route the additional NVMe signals from this controller to the drive bays.

Upgrade perspective

This card replaces the need for a server with fewer native NVMe connectors by multiplying the available high-speed drive ports. The jump is worthwhile when the R730XD workload demands more parallel NVMe throughput than the stock configuration provides.

Highlights

  • Adds NVMe capacity to PowerEdge R730XD servers
  • PCI Express Gen 3.0 x4 interface for fast data paths
  • Expands storage without replacing the backplane
  • Dell-engineered expander card for native compatibility
  • Controller design built for high-performance computing workloads

Questions about this item

What comes with the CDC7W expander card and what must be purchased separately?

The CDC7W card itself is supplied. NVMe SSDs and a compatible Dell PowerEdge R730XD server with a free PCI Express Gen 3.0 x4 slot must be purchased separately.

Which version of the CDC7W card should I choose for a PowerEdge R730XD?

Choose the CDC7W part number (also listed as 0CDC7W) — it is the specific PCI Express Gen 3.0 x4 NVMe expander validated for the PowerEdge R730XD.

What does the PCI Express Gen 3.0 x4 interface mean for real-world NVMe drive speeds in the R730XD?

The x4 lane width and Gen 3.0 signalling set the maximum throughput ceiling for each attached NVMe SSD; actual speed depends on the drive model and server workload.
