Cisco SD-AR1K-810132FH 8100 32x400G QSFP-DD 1RU | Enterprise Routing — SD-AR1K-810132FH

Move large-scale traffic with fewer chassis and less rack space using Cisco 8100 fixed-system hardware built around 32 x 400G QSFP-DD interfaces in a 1RU form factor. This platform is designed for environments that need high port density without adding operational complexity, making it a strong fit for aggregation, backbone, and data center interconnect roles. The fixed-system architecture simplifies deployment and standardization while preserving the throughput headroom required for demanding infrastructure. With 400G-class connectivity across 32 ports, teams can design for growth, reduce oversubscription pressure, and keep cabling and rack planning under control. That density is especially valuable when every RU and every uplink matters. As a Cisco platform, it aligns with enterprise network expectations for consistency, lifecycle planning, and integration into larger routing and switching strategies. For organizations comparing lower-density alternatives, this model stands out when the priority is to carry more traffic per rack unit and support a cleaner scale-out design. It is a practical choice for teams that need capacity now and room to expand without reworking the physical layer. Ideal For Data center aggregation for high-bandwidth server and storage traffic Backbone uplinks in enterprise campus or core network designs Data center interconnect where 400G port density is required Scale-out routing deployments that must preserve rack space Why This Product 1 Higher port density than lower-speed 1RU routing platforms 2 More rack-efficient than multi-rack modular designs 3 Better suited for 400G aggregation than mixed-speed edge gear 4 Simplifies physical planning with a fixed-system architecture
