Intel E810-DA4 25GbE 4-Port PCIe | Fiber Adapter, Lenovo, Enterprise

Increase server-side network density with a 4-port 25 GbE PCIe adapter designed for environments that need more bandwidth per slot. The Intel E810-DA4 is a strong fit for virtualization clusters, storage-intensive applications, and distributed workloads where multiple high-speed links help reduce congestion and simplify cabling. Four ports give infrastructure teams more flexibility when segmenting traffic, attaching to redundant fabrics, or separating application, storage, and management paths. That makes this adapter especially useful in racks where every PCIe slot has to earn its place. Instead of adding more cards or accepting lower link speeds, teams can consolidate connectivity around a single adapter with enterprise-class throughput. For procurement and architecture teams, the value is straightforward: fewer compromises on port count, speed, and server density. It is the kind of adapter chosen when the network is part of the performance plan, not just a utility layer. In modern data centers, that distinction matters when workloads are latency-sensitive, storage-aware, and always on.
