Yes. The Mellanox MCX311A-XCAT is a standard PCIe adapter card and works in PCIe 3.0 systems with an available slot. It uses a single SFP+ port for 10GbE, so your server also needs a compatible SFP+ transceiver or DAC cable and operating system support.

The MCX311A-XCAT is built for enterprise and data center use, with a compact plug-in card design and Mellanox ConnectX-3 controller. It supports 10 Gigabit Ethernet, PCIe 3.0 connectivity, and standards used in performance-focused server, storage, and virtualization environments.

The card is typically packaged in anti-static protection with secure outer packing to help prevent shipping damage to the PCIe network adapter and connectors. If you need low-profile brackets, cables, or SFP+ optics, check the listing carefully because accessories can vary by seller or lot.
