Product Description
The NVIDIA Mellanox ConnectX-3 MCX311A-XCAT is a single-port 10GbE SFP+ Ethernet adapter built around the MT27518A1-FCCR-XE controller. It delivers high-speed connectivity over a PCIe 3.0 x8 host interface and supports RoCE v1 remote direct memory access. This model shares the same core silicon and port specification as the MCX311A-XCBT in the same family, making it a solid fit for servers, storage nodes, or workstations that need low-latency single-port 10G connectivity — a practical entry point for SMB data centers upgrading from 1GbE to a 10G backbone.
