The Mellanox ConnectX-4 Lx EN Network Card (MCX653105A-EFAT) is a high-performance, dual-port Ethernet adapter designed to meet the demanding requirements of modern data centers. Supporting speeds of 10, 25, 40, and 50 Gb/s, this network card delivers exceptional bandwidth, ultra-low latency, and advanced hardware offloads for virtualization, storage, and cloud applications. It is an ideal solution for enterprises seeking to enhance server efficiency, reduce operational costs, and support scalable network infrastructure.
The ConnectX-4 Lx network card incorporates cutting-edge technologies including RoCE v2 for efficient remote direct memory access, end-to-end QoS and congestion control, overlay network encapsulation/decapsulation, and GPU Direct support for accelerated data movement between GPUs and network devices. It also supports advanced storage protocols like iSER and NFS over RDMA.
The NIC card offloads network processing tasks from the CPU through stateless offload engines, RoCE, and overlay network processing. It uses hardware-based encapsulation/decapsulation for tunneling protocols, allowing efficient traffic handling without CPU overhead. Multi-Host technology splits the PCIe interface into multiple independent interfaces, enabling direct connection for up to four hosts to a single network card.
This network interface card is widely used in:
