25G network card for high-speed links

The Graviton CX4121C ConnectX-4LX provides a single 25G Ethernet port for servers and workstations that need fast wired connectivity. It suits administrators upgrading rack-mount systems or builders adding bandwidth to storage clusters. The card arrives new and ready for deployment in compatible PCIe slots. No additional licensing is required for basic operation.

Straightforward PCIe installation

Insert the card into an available PCIe slot and secure the bracket; the physical fit follows standard half-height mechanics. Most modern Linux kernels and Windows Server releases include in-box drivers, yet some distributions need a manual module load or firmware update. Verify the slot width matches the card’s electrical requirement before powering on. Buyers who need dual-port redundancy or fibre media should select a different model.
