Dual-Port 25GbE Server Adapter

This dual-port network card adds two 25 Gigabit Ethernet connections over a single PCI Express 3.0 x8 slot. It is built for servers and workstations that need high-throughput, low-latency networking without occupying multiple expansion slots.

PCIe 3.0 x8 Host Requirement

The adapter requires a free PCIe 3.0 x8 lane from the host system and compatible 25GbE switching infrastructure to operate at rated speed. It consolidates two high-speed links into one card, freeing an additional slot for other expansion cards.

Questions about this item

Does the PCIe 3.0 x8 interface cap sustained 25 GbE throughput on both ports?

The card uses a PCIe 3.0 x8 host link, which provides enough bandwidth for dual 25 GbE line-rate traffic.

What is the typical power draw when both 25 GbE ports run continuously?

The ConnectX-4 Lx controller is rated for low-power operation, and the board draws only the power supplied through the PCIe slot.
