Single-port 10GbE adapter

The Intel X520DA1OCP is a single-port 10Gbps Ethernet network card built for servers and workstations that need high-throughput wired connectivity. It plugs into a PCI Express x8 slot and presents one SFP+ cage for a compatible transceiver.

PCIe x8 host connection

The card requires an available PCIe x8 lane and a free SFP+ transceiver module to complete the link. Its low-profile bracket fits standard and dense chassis, leaving adjacent slots accessible for additional expansion cards.

Supported networking standards

On-board firmware implements IEEE 802.1Q VLAN tagging, 802.1p priority queuing, 802.3ad link aggregation, 802.1ae MACsec encryption and 802.1as precision time protocol. The adapter also enables FCoE for unified storage traffic and carries FCC Class B, UL, VCCI, C-Tick, BSMI and RoHS compliance marks.

Questions about this item

What throughput limit appears first when the X520DA1OCP runs at full 10Gbps load?

The PCI Express x8 interface and single 10Gbps SFP+ port set the hard ceiling, so sustained traffic cannot exceed 10Gbps in either direction.

How much heat and power does the card produce during all-day operation?

The adapter draws power only from the PCIe slot and has no onboard fan, so thermal output stays low enough for standard server airflow without extra cooling.

Which transceiver must I already own for the SFP+ slot to work?

Any 10Gbps SFP+ module — short-reach, long-reach or direct-attach copper — that complies with the IEEE 802.3 standard listed for this adapter.
