Single-port 10 GbE adapter for servers

This 10Gtek card puts a single SFP+ port on a PCIe 2.0 x8 lane using the Intel 82599EN controller. It targets administrators who need 10 Gbps fibre or direct-attach links in rack-mount or low-profile chassis. Driver media and both full-height and low-profile brackets are included. The card does not support hot-swap insertion.

Throughput headroom at 10 Gbps line rate

The SFP+ cage accepts 10 Gbps modules, DAC or AOC cables, delivering full-duplex 10 Gbps bandwidth. Jumbo frames up to 9.5 KB reduce CPU overhead for iSCSI, FCoE or NFS storage traffic. A single port means aggregate throughput tops out at 10 Gbps; multi-port link aggregation or 25 Gbps uplinks require additional cards.

Standard operating envelope 0 °C to 55 °C

The Intel 82599EN controller is rated for continuous operation between 0 °C and 55 °C without exotic cooling. Passive heatsink dissipation keeps acoustic impact negligible in typical server airflow. Power draw is limited to the PCIe 2.0 x8 slot envelope, so no auxiliary power connector is needed.

Questions about this item

Will the PCIe 2.0 x8 card run in my older motherboard that only has PCIe x16 slots?

Yes, the PCIe 2.0 x8 interface fits both x8 and x16 slots and will operate at x8 speed in either slot.

How can I verify the 82599EN controller is recognised and the 10Gbps link is active after installing the driver?

Check Device Manager or lspci for the Intel 82599EN entry, confirm the SFP+ module shows a link light, and run a throughput test to see 10Gbps speeds.

Does the box include a transceiver or DAC cable for the SFP+ port, or must I buy one separately?

The package contains the adapter, a full-height bracket, a low-profile bracket and a driver CD; SFP+ modules, DAC or AOC cables are not included and must be purchased separately.
