10Gb PCI-E SFP+ Network Card

This single-port 10Gb PCI-E network card uses an Intel 82599EN controller to deliver 10Gb/s connectivity through an SFP+ port. It fits both standard and low-profile brackets for use in servers or desktop cases. The card targets administrators who need a direct 10Gb Ethernet link without dual-port expense.

PCI Express Lane Limit

The adapter operates over a PCI Express interface that caps throughput at the lane width installed in the host system. A 4-lane slot provides full 10Gb/s line rate while a narrower slot reduces available bandwidth. The Intel 82599EN controller supports I/O virtualization to maintain stability under load.

Single Port Capacity Headroom

One SFP+ port handles a single 10Gb/s link using transceiver modules, direct-attach cables or active optical cables. The design suits point-to-point server uplinks or workstation connections where a second port is unnecessary. Environments requiring link redundancy or aggregated throughput need a dual-port alternative.

Questions about this item

Should I pick the single SFP+ version or look for a dual-port card?

The card has one SFP+ port, so choose it when you only need a single 10 Gb link; a dual-port model would be required for two simultaneous connections.

What real throughput will I see from the 10 Gb rating once the card is installed?

The Intel 82599EN controller delivers a 10 Gb/s line rate per port, so actual throughput approaches 10 Gb/s when paired with a compatible transceiver and switch.

Does the PCI Express 4.0 interface cap the 10 Gb speed in practice?

The adapter uses a PCI Express interface that provides ample bandwidth for the 10 Gb/s port, so the bus does not limit the rated speed.
