The Mellanox ConnectX-4 Lx EN MCX4121A-XCAT is an advanced dual-port Ethernet network card engineered for modern data center and enterprise applications. This high-performance NIC card delivers 10, 25, 40, and 50Gb/s connectivity through SFP28 interfaces, featuring comprehensive hardware offload capabilities that optimize network performance while reducing CPU overhead. Designed for cloud infrastructure, virtualization environments, and high-performance computing, this adapter provides a scalable solution for evolving network demands with exceptional reliability and efficiency.
This sophisticated network card incorporates Mellanox's innovative Multi-Host® technology, allowing multiple servers to connect to a single adapter, dramatically reducing infrastructure costs and complexity. The card features hardware-based overlay network encapsulation/decapsulation, GPUDirect® RDMA acceleration, and sophisticated traffic management with quality of service (QoS) controls. While the ConnectX-6 series offers higher maximum bandwidth, this adapter provides exceptional value for 10-50GbE applications with a robust feature set that meets most enterprise requirements without unnecessary overhead.
The ConnectX-4 Lx EN NIC card operates through dedicated hardware engines that offload network processing tasks from the host CPU, including TCP/UDP/IP stateless processing, checksum computation, packet segmentation, and interrupt management. For virtualized environments, the card implements Single Root I/O Virtualization (SR-IOV) to provide dedicated adapter resources with guaranteed isolation for virtual machines, significantly improving performance compared to software-based virtualization solutions while substantially reducing CPU utilization and improving overall system efficiency.
We provide comprehensive technical support services including pre-sales consultation, system integration assistance, and post-sales troubleshooting. All products include standard warranty coverage with extended protection plans available for enterprise deployments. Our global logistics network ensures timely delivery to customers worldwide, and we offer flexible procurement solutions for large-scale deployments of this advanced network card solution, including volume pricing, customized configuration options, and integration services tailored to specific environment requirements.
Q: What distinguishes the ConnectX-4 Lx from the ConnectX-6 series adapters?
A: While the ConnectX-6 series offers higher maximum speeds (up to 200Gb/s) and enhanced security features, the ConnectX-4 Lx provides excellent performance for 10-50GbE applications at a more accessible price point, making it ideal for enterprise deployments where extreme bandwidth isn't the primary requirement but reliability and feature completeness are essential.
Q: Is this network card compatible with existing network infrastructure?
A: Yes, the card is fully backward compatible with lower-speed Ethernet standards and can interoperate with existing network switches supporting SFP28 interfaces, providing a smooth upgrade path for legacy environments without requiring complete infrastructure overhaul while maintaining investment protection.
Q: What type of cabling is recommended for 25GbE operation?
A: You can use SFP28 DAC (Direct Attach Copper) cables for shorter distances or optical transceivers with appropriate fiber cables for longer runs, depending on distance requirements, existing infrastructure compatibility, and specific performance characteristics needed for your application environment.
