Dell QLogic QL41262 25G Dual Port CNA

The Dell QLogic QL41262 is a converged network adapter providing dual 25GbE SFP28 connectivity for Dell PowerEdge servers. It unifies Ethernet, iSCSI, and FCoE traffic on a single PCIe 3.0 interface. The controller uses QLogic FastLinQ architecture for efficient data processing. This new part carries Dell part number 415DX.

Fits PowerEdge R640 R740 R740XD R840 R940

This adapter suits administrators upgrading compatible Dell PowerEdge rack servers to 25GbE converged networking. It supports SR-IOV for virtualized and hyper-converged infrastructure deployments. Buyers needing different port speeds, port counts, or server compatibility should verify requirements before purchase. The green PCB indicates standard Dell OEM manufacturing.

Dual 25GbE SFP28 via PCIe 3.0

The decisive specification is the dual 25GbE SFP28 interface operating over PCIe 3.0. This determines the switch optics, cabling, and server slot compatibility required for deployment. Confirm the target PowerEdge model supports this adapter and that 25GbE SFP28 transceivers match the network fabric. Part number 415DX identifies the correct Dell spare.

Questions about this item

What PCIe generation does the QLogic QL41262 use, and what bandwidth ceiling does that impose?

The adapter runs on PCIe 3.0, limiting each lane to 8 GT/s; with a x8 slot the practical ceiling is roughly 64 Gb/s aggregate, so the dual 25 GbE ports can run at line rate.

What physical slot and bracket height does the 415DX card require in a PowerEdge chassis?

It needs a full-height PCIe 3.0 x8 slot with a standard bracket; the green PCB and dual SFP28 cages fit the R640, R740, R740XD, R840 and R940 server form factors.

How is the adapter installed, and which step is most often missed?

Power down the server, open the chassis, insert the card into a free PCIe 3.0 x8 slot, secure the retention screw, connect SFP28 transceivers and cables, then enable the CNA in the system BIOS and install the QLogic FastLinQ driver — skipping the BIOS enable step is the common error.
