Dual-port 10 Gbps SFP+ server adapter

The Intel X520-DA2 E10G42BTDA is a dual-port 10 Gbps SFP+ network interface card built for servers and workstations that need high-throughput wired connectivity. It plugs into a PCI Express 2.0 x8 slot and uses a low-profile form factor with both brackets supplied.

Installation notes

The card installs in any compatible PCI Express 2.0 x8 or larger slot and ships with both low-profile and full-height brackets for flexible mounting. Common issues include using SFP+ modules or cables that are not validated for 10 Gbps operation, which can prevent link negotiation or cause intermittent errors.

Deciding specification

The defining specification is the dual-port 10 Gbps SFP+ interface over PCI Express 2.0 x8, which sets the maximum throughput and cabling options. If your deployment requires a different port count, a different bus interface, or onboard transceiver types, this adapter will not match the requirement.
