Intel E810-DA4 25GbE 4-Port OCP | Lenovo Server Fiber Adapter

Built for environments that need more bandwidth per rack unit, the Intel E810-DA4 25GbE 4-port OCP adapter delivers four high-speed Ethernet ports in a form factor designed for modern server platforms. It is a strong fit for infrastructure teams standardizing on OCP-based networking while pushing more traffic through fewer adapters. At 25 GbE per port, this class of adapter is aimed at workloads that have outgrown 10 GbE but do not yet require the cost and optics overhead of faster uplinks. That makes it a practical choice for virtualization clusters, software-defined storage, database servers, and leaf-spine fabrics where predictable throughput and port density directly affect performance. For buyers, the value is in the balance: more bandwidth, more ports, and a cleaner server design without moving to oversized networking hardware. In enterprise refresh projects, that translates into better rack efficiency, fewer bottlenecks, and a network layer that can keep pace with storage and compute growth. If your deployment standard calls for OCP networking and 25 GbE access, this adapter belongs on the short list.
