Lenovo CN4052R 10Gb Dual Port Virtual Fabric Adapter | Ethernet, PCIe

Improve server connectivity without adding unnecessary complexity. The Lenovo CN4052R 10Gb Dual Port Virtual Fabric Adapter is designed for environments that need higher bandwidth, cleaner traffic segmentation, and dependable performance from a single PCIe adapter. Dual 10 Gb ports give infrastructure teams the headroom to support virtualization, storage traffic, and application workloads on a compact footprint. Virtual fabric support helps align network design with modern data center requirements, reducing the need for multiple discrete adapters while preserving clear separation between traffic types. That can simplify cabling, streamline server builds, and make it easier to standardize across fleets. For teams refreshing older 1 Gb infrastructure or expanding host density, this adapter provides a practical path to better throughput and more efficient server design. Built for Lenovo server platforms, the CN4052R fits procurement plans that value compatibility, consistency, and long-term operational stability. It is a strong choice where network performance matters, but so does keeping the hardware layer clean, manageable, and ready for consolidation.
