Mellanox NVIDIA CX4421A ConnectX-4 Lx Dual Port SFP28 25GbE OCP 2.0 Mezzanine Network Interface Card (NIC) MCX4421A-ACUN

Enhance your Open Compute infrastructure with the Mellanox NVIDIA ConnectX-4 Lx EN MCX4421A-ACUN, a high-performance dual-port 25GbE OCP 2.0 mezzanine Network Interface Card (NIC) designed for cloud, virtualization, hyperscale, and enterprise data center environments. Featuring two SFP28 ports and built on the reliable ConnectX-4 Lx architecture, this adapter delivers low-latency connectivity, advanced network acceleration, and efficient virtualization performance for modern workloads.

The MCX4421A-ACUN supports up to 25GbE per port and is backward compatible with existing 10GbE SFP+ infrastructure, making it an ideal upgrade path for evolving network environments. Advanced offload technologies including RoCE v1/v2, SR-IOV, VXLAN, NVGRE, GENEVE, and Erasure Coding acceleration help reduce CPU overhead while maximizing throughput and application performance.

Purpose-built for OCP 2.0 Type 1 mezzanine slots, this adapter integrates directly into compatible Open Compute servers without consuming valuable PCIe expansion slots.
