Dual-port 10 Gb SFP+ adapter for compact servers

This Intel-based network card adds two 10 Gbps SFP+ ports through a PCI-E 2.0 x8 slot. Its low-profile bracket fits space-constrained Dell PowerEdge rack and tower models from the 320, 420, 520, 620, 630, 720, 820 and 920 series. It targets administrators who need high-throughput links for virtualization or data-centre workloads.

Verify PCI-E x8 slot and SFP+ transceiver supply

Your chassis must provide a free PCI-E 2.0 x8 lane and physical clearance for a low-profile bracket. The card ships without transceivers or cables, so you must source compatible SFP+ modules and fibre or direct-attach copper separately. Confirm the server BIOS recognises the 942V6 part number before installation.

Low-profile bracket enables dense rack deployment

The included half-height bracket allows the adapter to sit in 1 U or blade chassis where a full-height card would not fit. No driver disc or management utility is bundled; current Linux and Windows Server releases include the necessary Intel driver in-kernel. The absence of onboard optics means port density and reach are defined entirely by the transceivers you choose.

Questions about this item

Does the X520-DA2 ship with SFP+ transceivers or must they be purchased separately?

The card provides two SFP+ cages only; compatible 10 Gbps transceivers and cables are sold separately.

Which part number identifies the low-profile version that fits the PowerEdge R620?

Part number 942V6 corresponds to the low-profile X520-DA2 qualified for the R620 and the other listed PowerEdge models.

What throughput does the PCI-E 2.0 x8 link deliver to each 10 Gbps port?

The x8 gen 2.0 interface supplies enough bandwidth for both ports to run at line-rate 10 Gbps simultaneously.
