Cisco UCSC-P-N6D25GF-D CX6Lx 2x25GbE SFP28 PCIe NIC | Enterprise — UCSC-P-N6D25GF-D

Sustain demanding server workloads with dual 25 GbE SFP28 connectivity in a PCIe x8 form factor. The Cisco-NVDA MCX631102AS-ADAT CX6Lx adapter is built for environments where network throughput, low-latency access, and predictable server-side performance matter more than commodity NIC pricing. This adapter fits Cisco UCS deployments that need to move more traffic per host without adding complexity at the rack level. Dual SFP28 ports provide the bandwidth needed for virtualization clusters, storage traffic, and high-density application tiers, while the PCIe x8 interface supports efficient integration into modern server platforms. For teams standardizing on Cisco infrastructure, this NIC helps preserve performance consistency across compute nodes and reduces the need to overprovision ports to compensate for slower adapters. It is a practical choice when the cost of congestion, retransmits, or underfed workloads is higher than the premium for a better-specified interface card. Use it where server connectivity is part of the performance plan, not an afterthought.
