Intel X520-DA2 dual-port 10Gbps adapter

The Intel X520-DA2 is a dual-port 10Gbps network adapter built for servers and workstations that need high-throughput Ethernet connectivity. It installs in a PCI-Express slot and presents two SFP+ cages for direct-attach or transceiver-based links.

PCI-Express add-in card with two SFP+ cages

The card occupies a single PCI-Express expansion slot and provides two SFP+ ports, freeing the builder from on-board 1GbE limits while leaving other slots available for storage or compute cards. SFP+ modules or direct-attach cables are sourced separately to match the link distance and fibre type required.

Sustained 10Gbps throughput for data-centre

Designed for continuous operation in virtualised and high-performance computing clusters, the adapter maintains line-rate 10Gbps traffic under extended load without throttling. RoHS-compliant construction and a lifetime limited warranty reflect its intended deployment in always-on server environments.

Questions about this item

Will the two SFP+ ports saturate the PCI-Express link under continuous 10Gbps traffic?

Each port runs at 10Gbps and the card occupies a single PCI-Express slot, so sustained line-rate traffic on both ports simultaneously can exceed the slot bandwidth.

How much heat does the adapter produce when both SFP+ links run all day?

The adapter is a passive plug-in card with no onboard fan; heat output depends on the SFP+ modules installed and the server chassis airflow.

Which SFP+ transceivers or direct-attach cables must I already own to use the card?

The card provides two SFP+ cages; you need compatible 10Gbps SFP+ optics or direct-attach cables that match your switch and cabling distance.
