Dual-port 10GbE copper adapter

The Intel X540T2BLK is a PCI Express 2.1 x8 network card with two RJ45 ports. It runs at 100 Mbps, 1 Gbps or 10 Gbps over copper cabling. The controller is the Intel Ethernet Controller X540. It fits low-profile and full-height brackets.

Suited for servers adding 10GBASE-T links

This card serves hosts that need dual 10 GbE connections on existing Cat 6 or Cat 6A runs. It supports SR-IOV for virtual machines and ships with drivers for VMware ESXi 5.x, 6.x and 7.x. Buyers who need fibre connectors or a single-port design should look elsewhere.

PCIe 2.1 x8 interface requirement

The adapter occupies a PCI Express 2.1 x8 slot. That electrical width decides whether the card fits the target platform. Category 6 cable reaches 55 metres; Category 6A reaches 100 metres at 10 Gbps.

Questions about this item

Should I pick the low-profile or full-height bracket for my server?

Both brackets are included so you can fit the card in either a 2.7-inch low-profile chassis or a standard full-height slot.

What does the 10 Gbps rating mean when the card is installed in a live server?

Each of the two RJ45 ports can auto-negotiate at 10 Gbps, 1 Gbps or 100 Mbps depending on the switch and cable you connect.

How does the PCIe 2.1 x8 interface limit real-world throughput?

The x8 lane width at PCIe 2.1 provides enough bandwidth for both ports to run at line-rate 10 Gbps simultaneously.
