Lenovo Mellanox ConnectX-4 2x25GbE SFP28 Adapter | Fiber Adapter

Keep critical workloads moving with dual 25 GbE SFP28 connectivity in a Lenovo-sourced Mellanox ConnectX-4 adapter. Designed for fiber uplinks in performance-sensitive servers, it gives infrastructure teams the bandwidth headroom needed for virtualization, storage access, and east-west traffic without forcing a platform redesign. This adapter is a strong fit when 10 GbE is no longer enough, but you still want a compact, standards-based path to higher throughput. The SFP28 interface supports modern fiber deployments and helps preserve rack density while scaling network capacity. For teams standardizing on Lenovo infrastructure, sourcing through the OEM simplifies procurement and keeps the part aligned with enterprise support expectations. Choose this model when you need more than basic connectivity. Dual-port 25 GbE capability helps reduce oversubscription at the server edge, while the Mellanox ConnectX-4 family is known for efficient data movement in demanding environments. It is a practical upgrade for organizations that value measured performance gains, not speculative features.
