A cloud service provider deploys the WS-X6816-10G-2T in its Catalyst 6500 chassis to aggregate 16 server rack uplinks at 10 Gbps each. Leveraging the DFC4’s wire-speed ASIC forwarding, the solution delivers sub-100 µs latency and 1:1 oversubscription, consolidating rack connectivity into a single module. The outcome is a 40% reduction in switch footprint, simplified cabling, and OPEX savings through centralized management and power efficiency.
A global trading firm integrates WS-X6816-10G-2T modules into its core Catalyst 6500 infrastructure to support ultra-low-latency order execution. The DFC4 offloads forwarding decisions to hardware, ensuring sub-microsecond packet transit and deterministic performance under peak load. Resulting benefits include guaranteed order-entry speeds, compliance with FINRA latency SLAs, and a measurable 25% reduction in trade execution time.
A multinational enterprise refreshes its campus backbone by installing WS-X6816-10G-2T line cards in Catalyst 6500 switches to deliver 16 flexible 10 GbE ports. The integrated DFC4 enables hardware-accelerated QoS, MPLS, and multicast services across all ports. This upgrade yields a four-fold increase in aggregate throughput, end-to-end service assurance for VoIP and video, and centralized policy enforcement for improved network uptime and security.
