Cisco DPX20/X10 Pluggable 4x10G NIC Module | 10GbE, Enterprise — RD21-4X10GNIC-3Y

Keep demanding workloads connected with a Cisco pluggable 4 x 10 GbE NIC module built for DPX20/X10 platforms. This module is suited for infrastructure teams that need compact, high-bandwidth network expansion without moving to a larger adapter footprint. With four 10 GbE ports, it supports traffic patterns that stress standard 1 GbE links: virtualization clusters, backup windows, storage-heavy applications, and aggregation points where multiple services converge. The pluggable design helps maintain a clean hardware profile while adding the throughput needed for modern server and appliance deployments. For procurement teams, the 3-year coverage adds a practical layer of lifecycle confidence. For architects, the value is straightforward: more bandwidth per module, fewer bottlenecks, and a Cisco-branded component aligned to the DPX20/X10 platform family. When the network path matters, this module gives you the capacity to keep critical services responsive under load.
