The NVIDIA Mellanox ConnectX-5 MCX556A-EDAT is a high-performance dual-port network card supporting both 100Gb/s InfiniBand and Ethernet connectivity. Designed for PCIe Gen4 servers, this NIC card delivers ultra-low latency, high message rates, and advanced hardware offloads for compute and storage applications.
The ConnectX-5 network card leverages cutting-edge technologies including RDMA, PCIe Atomic operations, and hardware-based congestion control. It supports NVMe-oF target offloading, T10 DIF, and storage protocols like SRP and iSER. This NIC card is also compatible with overlay networks such as VXLAN and GENEVE.
The ConnectX-5 adapter uses embedded intelligence to offload network, storage, and compute operations from the CPU. It enables direct memory access (RDMA) between servers and storage devices, reducing latency and CPU overhead. The card supports adaptive routing and out-of-order packet delivery for optimized performance in complex topologies.
