Lenovo NV BF-3 1PX400G DPU B3140H | Ethernet Adapter, Enterprise

Shift demanding packet processing away from the server CPU and keep critical workloads focused on application delivery. Lenovo NV BF-3 1PX400G DPU B3140H is designed for environments where network acceleration, isolation, and predictable throughput matter more than basic connectivity. With a single 400G-class interface, this adapter targets dense compute and storage fabrics that need substantial bandwidth in a compact footprint. It is a strong fit for modern infrastructure teams standardizing on accelerated networking for virtualization, distributed storage, and high-performance east-west traffic. By moving infrastructure services closer to the network edge, the DPU helps reduce host overhead and improve consistency under load. This model is positioned for buyers who need more than a commodity NIC. It supports advanced offload use cases where the cost of congestion, CPU contention, or latency spikes is measured in service impact. For enterprise teams evaluating premium network adapters, the value is in preserving server resources while sustaining demanding traffic patterns.
