NVidia Mellanox ConnectX®-5 EN — High-Performance Network Adapter

High-end computing environments and data centers require networking solutions that offer low latency and high throughput. The nVidia Mellanox ConnectX®-5 EN network adapter meets these demands with support for 25Gb Ethernet and a dual-port design with SFP28 connectors. This card is ideal for applications such as machine learning, data analytics, or environments with high data rate requirements. With PCIe switch offload and NVMe over Fabric, it minimizes CPU load and ensures maximum efficiency.

Low Latency and High Throughput

ConnectX®-5 EN uses RoCE (RDMA over Converged Ethernet) technology, which provides extremely low latency and high performance. This technology is key for applications where fast data transfer between nodes is essential, including machine learning systems and data storage. The card supports Switch AdaptiveRouting and multipath reliability, ensuring smooth operation in complex topologies such as DragonFly.

Offload function for CPU optimization

One of the unique features of ConnectX®-5 is support for Burst Buffer offload, which allows control operations to be performed in the background without disrupting the main CPU operations. This feature is invaluable for high-performance systems where resource efficiency must be maximized. In addition, Dynamic Connected Transport (DCT) technology ensures extreme scalability, which is crucial for modern computing and storage systems.
