10Gb SFP+ NIC for servers

The 10Gtek single-port network card uses an Intel 82599EN controller to deliver 10Gbps Ethernet over a PCI-Express x8 interface. It targets administrators who need reliable 10 Gigabit connectivity in Windows Server, Linux or VMware ESX environments. A standard bracket and a low-profile bracket are included for flexible installation. The card does not support hot-swapping.

Sustained throughput with virtualization support

The Intel 82599EN controller provides I/O virtualization to keep servers stable under continuous load. Storage protocols such as iSCSI, FCoE and NFS run over the single SFP+ port, which accepts SFP+ modules, direct-attach cables or active optical cables. Windows 11 operation requires correct driver setup as noted by the supplier.

Operating range and slot compatibility

Rated for 0°C to 55°C, the adapter fits both PCI-Express x8 and x16 slots without additional power connectors. The low-profile bracket allows deployment in compact server chassis while maintaining airflow. No hot-swap capability means planned maintenance windows are required for module changes.

Questions about this item

How much heat does the Intel 82599EN controller generate when the card runs continuously at 10Gbps?

The card is rated for an operating temperature range of 0°C to 55°C, so the controller stays within that envelope during sustained 10Gbps traffic.

Which SFP+ module or cable must I already own to get a link on the single SFP+ port?

You need a 10 Gigabit SFP+ transceiver, a direct-attach copper cable or an active optical cable that matches your link distance and fibre type.

Will the PCIe x8 lane negotiate down to x4 or x1 on an older motherboard that only has x4 or x1 slots?

The card fits physically in x8 or x16 slots; it will not operate in x4 or x1 slots because the edge connector requires the full x8 electrical interface.
