Dual-port 10 Gb Ethernet adapter

The Intel X520-DA2 adds two 10 Gb Ethernet ports to a server or workstation through a single PCIe slot. It ships with a low-profile bracket for compact chassis installations. The card targets administrators who need high-throughput wired connectivity for storage, virtualization or backup traffic.

PCIe lane and cabling limits

Each port runs at 10 Gb/s, so the host slot must supply enough PCIe bandwidth to avoid becoming the bottleneck. Cable length and quality also constrain reliable operation; exceeding the electrical reach of the chosen copper or fibre media will drop the link to a lower speed or cause errors.

Dual-port 10 Gb density

Two 10 Gb ports on one bracket halve the slot count compared with single-port cards, which matters when expansion space is scarce. Buyers who need more than two ports or a different media type will need additional adapters.

Questions about this item

Should I pick the dual-port 10Gb version or a single-port alternative?

The X520-DA2 ships with two 10Gb ports and a low-profile bracket, giving twice the throughput of a single-port card in the same slot.

What does the 10Gb rating deliver inside a server chassis?

Each port can move up to 10 gigabits per second, so the adapter provides 20 Gb/s aggregate bandwidth when both ports are active.

Which slot standard does the X520-DA2 use and what throughput does that limit?

The card installs in a PCIe slot; the bus width and generation of that slot determine the practical ceiling for the two 10Gb ports.
