Lenovo 81Y5398 2-Port 10Gb SFP+ Network Adapter | Enterprise NIC

Move more traffic through fewer ports with Lenovo’s dual-port 10 GbE SFP+ adapter. Built for server environments where bandwidth, latency, and port density matter, this adapter gives you two high-speed fiber-ready interfaces in a compact footprint. It is a practical fit for virtualization clusters, storage networks, and aggregation layers that need consistent throughput without adding unnecessary complexity. For teams refreshing older 1 GbE infrastructure, the 81Y5398 creates a straightforward upgrade path to 10 GbE while preserving a familiar Lenovo deployment model. Dual SFP+ ports support flexible uplink design, whether you are segmenting traffic, building redundancy, or separating application and storage paths. That makes it easier to scale performance where it matters most: between hosts, switches, and shared resources. This adapter is suited to procurement cycles where compatibility and lifecycle consistency matter as much as raw speed. It is the kind of component that earns its place in enterprise builds by reducing bottlenecks, supporting denser workloads, and keeping network architecture clean.
