Cisco 8712 2RU 6.4T K100 System | Data Center Switch, Enterprise — SD-AR1K-8KMOD1MC

Move large east-west traffic volumes through a compact 2RU footprint with a Cisco platform engineered for demanding data center fabrics. The 6.4T K100 system is built to support high-density switching where rack space, airflow direction, and operational consistency matter as much as raw throughput. This configuration is suited to teams standardizing on a core or aggregation layer that must keep latency-sensitive workloads connected while preserving clean thermal design across the rack. Front-to-back airflow aligns with common hot-aisle/cold-aisle layouts, helping simplify deployment in structured environments. For infrastructure teams, the value is in the balance: substantial switching capacity in a space-efficient chassis, with a design that fits into enterprise rack planning rather than forcing it. That makes it a strong fit for data center refreshes, fabric expansion, and environments where uptime depends on predictable network behavior and disciplined physical design. Ideal For Core switching in enterprise data centers Aggregation layer deployment in leaf-spine fabrics Network refresh projects requiring compact high-throughput switching Rack-standardized environments with front-to-back cooling Why This Product 1 Higher fabric capacity than compact access switches 2 2RU footprint preserves rack space in dense environments 3 Front-to-back airflow fits standard data center cooling 4 Modular system design suits core and aggregation roles
