C3KX-SM-10G Use Case
Data Center Top-of-Rack 10G Server Aggregation
In a high-density e-commerce data center, IT architects install the C3KX-SM-10G Catalyst 3K-X 10G Service Module in Catalyst 3750-X switches to aggregate 48×1G and 10G server links over single-mode fiber. This delivers full line-rate 10 Gbps uplinks for east-west traffic, eliminates bandwidth bottlenecks, reduces latency by 30%, and simplifies cabling, enabling seamless scaling and uninterrupted peak-hour transactions.
Enterprise Campus Backbone 10G Resilient Uplinks
A global corporation deploys C3KX-SM-10G modules in a Catalyst 3560-X stacked core to interconnect five campus buildings via redundant 10 Gbps fiber uplinks. The solution achieves sub-50 ms failover, supports HD video conferencing and mission-critical VoIP, and centralizes security policies. The outcome: 99.99% application availability, consistent user experience across sites, and streamlined network operations.
Virtualized Cloud Edge High-Speed Inter-Switch Links
A cloud service provider integrates the C3KX-SM-10G Catalyst 3K-X 10G Service Module into Catalyst 3750-X leaf switches to trunk 10 Gbps connections to hyper-converged virtualization clusters. This configuration guarantees low-latency VM live-migrations, rapid storage replication, and robust software-defined overlay performance. Results include 40% faster migration windows, SLA-backed throughput, and improved tenant satisfaction.
