Description
The Dell 31F28, powered by the Mellanox ConnectX-4 controller, is a cutting-edge network adapter designed for the most demanding data center environments. It features two 25 Gigabit Ethernet SFP28 ports, offering significantly higher bandwidth than traditional 10GbE solutions. This makes it ideal for high-performance computing (HPC), artificial intelligence (AI), machine learning (ML), and high-speed storage applications where data throughput is critical. The adapter utilizes a PCIe 3.0 x16 interface, providing ample bandwidth to the host system and ensuring that the network card's capabilities are fully utilized. The SFP28 ports allow for the use of various transceivers, including 25GBase-SR for short distances and 25GBase-LR for longer reaches, providing flexibility in network design. Its low-latency architecture is crucial for real-time applications and tightly coupled clusters. With advanced features such as RDMA (Remote Direct Memory Access) over Converged Ethernet (RoCE), NVMe-oF support, and hardware offloads, the Dell 31F28 significantly enhances application performance and reduces CPU overhead. This adapter is a key component for modernizing data centers and enabling the next generation of high-performance networking solutions.
