The Mellanox ConnectX-5 MCX516A-BDAT is a high-performance dual-port network card designed for next-generation data centers. It delivers up to 100Gb/s per port Ethernet connectivity with ultra-low latency (750ns) and advanced offload capabilities for cloud, storage, and telecommunications workloads. This NIC card supports PCIe 4.0 and is available in OCP 3.0 form factor, making it ideal for hyperscale and enterprise deployments.
The ConnectX-5 leverages cutting-edge technologies including:
The ConnectX-5 network card offloads network, storage, and virtualization processing from the CPU to the adapter itself. It uses hardware-based encapsulation/decapsulation for overlay networks (VXLAN, GENEVE), processes NVMe-of commands without host intervention, and enables direct memory access between servers and storage via RDMA. This significantly reduces latency and CPU overhead.
