C3KX-NM-10GT= Use Case
High-Density Data Center Server Aggregation with C3KX-NM-10GT=
In a mid-size data center running virtualization and database clusters, IT deploys the Catalyst 3K-X 10G-T network module (C3KX-NM-10GT=) in Catalyst 3650/3850 switches to aggregate eight 10GbE copper links from rack servers. This deployment delivers 80 Gbps of non-blocking bandwidth, reduces oversubscription from 4:1 to 1:1, and ensures low-latency connectivity for high-performance workloads.
Enterprise Campus Uplink Upgrade for High-Bandwidth Services
A global enterprise campus supporting HD video conferencing, VoIP phones and Wi-Fi 6 access points upgrades its distribution layer with the Catalyst 3K-X 10G-T network module. Plugged into Catalyst 3000-X switches, C3KX-NM-10GT= provides eight 10G-T uplinks over existing copper infrastructure—boosting uplink capacity by 400%, simplifying cabling, and guaranteeing QoS for real-time applications.
Low-Latency Virtual Desktop Infrastructure (VDI) Deployment
A financial services firm deploying VMware Horizon VDI requires predictable, sub-millisecond network performance. By integrating the C3KX-NM-10GT= Catalyst 3K-X 10G-T network module into its Catalyst 3850 aggregation switches, the firm establishes eight dedicated 10GbE uplinks to server clusters. The result is a 60% reduction in latency and seamless user experience during market opening peaks.
