Dual-port Gigabit PCIe x1 network card

This 10Gtek adapter adds two RJ-45 Gigabit Ethernet ports through a single PCIe 1.0 x1 slot. It uses the Intel 82571 controller and supports 10/100/1000 Mbps speeds. The card fits 32/64-bit PCI bus systems and works with Windows, Linux, FreeBSD, VMware ESXi and SUSE Linux Enterprise Server. It is a new component for wired networking upgrades.

Suitable uses and limits

This card suits administrators adding a second wired link to a server or workstation that has a free x1 slot and does not need Wake-on-LAN or SR-IOV. It also fits virtualisation hosts running supported hypervisors where jumbo frames up to 9.5 KB are required. Builders who need Wake-on-LAN, SR-IOV, hot-plug capability or more than two ports should choose a different adapter.

Deciding specification — Intel 82571 controller

The Intel 82571 controller defines the feature set: dual-port Gigabit operation, PCIe 1.0 x1 interface, jumbo-frame support to 9.5 KB and the listed operating-system compatibility. It also means Wake-on-LAN and SR-IOV are absent and hot-plug is not supported. Verify that your workload can accept those constraints before purchasing.

Questions about this item

What does the 1000 Megabytes Per Second transfer rate mean for the two Gigabit ports?

The 1000 MB/s rate reflects the combined wire-speed of both RJ-45 ports running at 1000 Mbps each; actual throughput depends on system load and PCIe 1.0 x1 bus limits.

How does the PCIe 1.0 x1 interface affect performance?

The card uses a single PCIe 1.0 lane, which caps total bus bandwidth below the combined dual-port wire rate, so sustained simultaneous traffic on both ports will be limited by the slot.

What slot and bracket space does the card need to install?

It requires a free PCI Express x1 slot (or larger) and a standard low-profile bracket for the dual RJ-45 connectors; the board fits 32/64-bit PCI bus systems.
