Cisco NXN-K35-8X= Nexus X40 2-Port QSFP+ SmartNIC | Enterprise, FPGA — NXN-K35-8X=

Keep server-side networking aligned with the demands of modern infrastructure using the Cisco Nexus X40 2-port QSFP+ SmartNIC, MPN NXN-K35-8X=. This adapter is designed for environments where port density, host connectivity, and programmable acceleration matter more than commodity NIC features. With 2 QSFP+ ports, the card is suited to high-bandwidth uplinks and aggregation paths that need consistent throughput inside a compact footprint. The KU035 FPGA adds a hardware foundation for workloads that benefit from specialized processing at the edge of the server, helping move selected tasks away from the CPU and into the network path. That combination makes this model a strong fit for teams standardizing on Cisco infrastructure and looking for a SmartNIC that supports more than basic connectivity. It is the kind of component you choose when the cost of a weak link is measured in performance headroom, not just port count. For enterprise buyers, the value is in the right mix of density, acceleration, and platform alignment.
