In hyperscale data centers, the Cisco WS-X6816-10T-2T module aggregates 16 10G server ports onto two 10G uplinks in a Catalyst 6500 chassis, simplifying cabling and reducing rack footprint. Benefit: Delivers 320 Gbps full-duplex throughput with sub-3 µs latency, optimizes port density, and cuts OPEX by up to 30%.
When campus networks exceed existing uplink capacity, integrating the WS-X6816-10T-2T 16-port 10G module with DFC4 into a Cisco 6500 enables seamless bandwidth expansion. Outcome: Provides non-disruptive insertion, up to 2 Tbps per‐slot switching fabric, enhanced link availability, and consistent high-performance for voice, video, and data services.
Financial trading firms and HPC clusters deploy the WS-X6816-10T-2T module to interconnect servers with deterministic, line-rate forwarding via DFC4. Benefit: Achieves sub-1 µs port-to-port latency, eliminates jitter, supports tens of thousands of simultaneous flows, and secures a competitive edge in latency-sensitive environments.
