Two-port SFP controller for PCIe 2.0 x1

The StarTech P021GINETWORKCARD adds two gigabit SFP ports to a workstation or server using a single PCI Express 2.0 x1 slot. It is built around the Intel I350-AM2 chipset and targets administrators who need low-latency, low-CPU-overhead Ethernet for virtualised workloads and business services.

Bandwidth capped at the x1 gen-2 lane

The host interface is PCI Express 2.0 x1, so aggregate throughput cannot exceed the lane’s 5 GT/s signalling rate. Both ports share this single lane, making the card unsuitable for sustained line-rate traffic on two gigabit links simultaneously.

Upgrades single-port or on-board copper NICs

It replaces a single-port copper adapter or basic integrated NIC when SFP fibre uplinks or a second isolated gigabit link are required. The jump is worth it only if the chassis has a free x1 slot and the deployment needs VMDq, SR-IOV, PXE boot or 9K jumbo frames; buyers who need more than two ports or 10GbE speeds must choose a different controller.

Questions about this item

Should I choose the single-port or two-port version of this card?

This model provides two SFP ports so you can add two 1GbE SFP modules in one PCIe 2.0 x1 slot.

What throughput will I see from the 1GbE SFP ports in a real server?

Each port runs at 1GbE line rate with low latency and low CPU utilisation thanks to the Intel I350-AM2 chipset.

Does the PCIe 2.0 x1 interface limit the two 1GbE ports?

The x1 lane supplies enough bandwidth for both 1GbE ports simultaneously without a bottleneck.
