NVIDIA MCX516A-CCAT ConnectX-5 EN Adapter Card 100GbE

The NVIDIA ConnectX-5 EN Adapter Card MCX516A-CCAT delivers high-performance Ethernet connectivity with support for up to two 100GbE ports, making it ideal for demanding data center and enterprise applications. Featuring a PCIe 3.0 x16 interface, this plug-in card offers a flexible pipeline architecture capable of handling workloads with ultra-low latency of approximately 750 nanoseconds and processing up to 200 million messages per second. When used with open source Data Path Development Kit (DPDK), it achieves an impressive 197 million packets per second, ensuring high throughput and efficient network operations. This adapter is designed to support a variety of network speeds—including 1, 10, 25, 40, 50, and 100 GbE—making it adaptable to diverse infrastructure requirements. Its compatibility with multiple form factors, including stand-up PCIe, OCP 2.0, and OCP 3.0, provides deployment flexibility across different server architectures.

The NVIDIA ConnectX-5 EN Adapter Card incorporates advanced features such as embedded PCIe switches, NVMe over Fabric offloads, and hardware-based Signature Handover (T10-DIF) accelerations to optimize storage and network performance. It also enhances virtual switch and router offloads, reducing CPU load while increasing packet throughput, making it well-suited for telecommunications, cloud data centers, and high-performance computing environments. The card supports RoCE for overlay networks, offering low-latency, lossless transport over RDMA, and features adaptive routing on reliable transports for improved data integrity and flow control. Its innovative design also includes backend switch elimination through host chaining, burst buffer offloads for background checkpointing, and tag matching and rendezvous offloads for efficient data management.

Constructed to meet RoHS compliance and ODC compatibility standards, this NVIDIA adapter is environmentally friendly and built for longevity with a one-year limited warranty. Its various form factors and rich feature set make the ConnectX-5 EN Adapter an essential component for high-speed, reliable Ethernet networking in modern data centers.
