Single-Port 25GbE ConnectX-4 Adapter

This Mellanox ConnectX-4 card delivers a single 25 Gigabit Ethernet connection over a PCI Express 3.0 slot. It is built for servers or workstations that need higher bandwidth than standard Gigabit links.

Suited for single-link server uplinks

The card fits environments where one 25 Gb/s port satisfies the uplink requirement. It is not for systems that need dual-port redundancy, fibre-channel connectivity, or speeds beyond 25 Gb/s.

PCI Express 3.0 x8 host interface

Installation requires a free PCIe 3.0 slot with sufficient electrical lanes; the board will negotiate at the slot's available width. Verify that your platform provides this interface before purchase.
