ConnectX-3 Pro network adapter
The Mellanox ConnectX-3 Pro is a 10/40/56 Gigabit Ethernet card built for PCI Express Gen3 servers in public and private clouds, enterprise data centres, and high-performance computing clusters. It targets workloads such as clustered databases, parallel processing and transactional services that demand high throughput and low latency. Buyers needing a single-port 1 Gigabit NIC for a desktop will not be served by this product.
Sustained load behaviour
Hardware offload engines for overlay-network tunnelling move encapsulation and decapsulation off the host CPU, keeping throughput steady during long-running database syncs or parallel compute jobs. The adapter maintains consistent bandwidth across extended transfers rather than peaking only in short bursts. Environments that rely on software-only packet processing will not see the same efficiency gains.
Installation notes
The card installs into a standard PCI Express Gen3 slot and requires compatible driver support in the host operating system. Misaligned bracket height or missing kernel modules are the most common reasons the adapter fails to initialise. Systems limited to PCI Express Gen2 or lacking driver packages for this hardware will not achieve the rated connectivity.

Questions about this item
How much power does the 40 Gigabit Ethernet card draw when running all day?
The ConnectX-3 Pro adapter card uses hardware offload engines to handle 10, 40, and 56 Gigabit Ethernet traffic, reducing CPU load and lowering cost per operation in continuous data-center workloads.
What slot and server generation are required to install this 10/40/56GbE card?
The card is designed for PCI Express Gen3 servers, so the host system must provide a compatible PCIe Gen3 slot for the adapter to operate.
Will the ConnectX-3 Pro card work with older PCIe Gen2 servers I still use?
The adapter targets PCI Express Gen3 servers used in public and private clouds, enterprise data centers, and high-performance computing clusters.
