Cisco DPX20/X10 Pluggable 4x10G SR NIC Module | 10GbE, Enterprise — RD21-4X10GBPSR-5Y

Keep critical workloads connected with a pluggable 4 x 10 GbE SR NIC module designed for Cisco DPX20/X10 platforms. This module is built for environments that need compact, high-throughput connectivity without adding unnecessary hardware complexity. By concentrating four 10 GbE links into a single module, it helps preserve chassis space while supporting the bandwidth demands of virtualization hosts, storage traffic, and east-west application flows. Short-reach SR connectivity is a strong fit for data center racks where fiber runs stay controlled and predictable. That makes this module a practical choice for teams standardizing on 10 GbE access while maintaining clean cabling and consistent performance across server clusters. The pluggable design also supports straightforward integration into compatible Cisco systems, helping infrastructure teams keep deployment patterns uniform. The 5-year term adds planning confidence for organizations that want to align network hardware with longer refresh cycles and support expectations. For procurement teams, that means fewer replacement decisions in the near term. For architects, it means a known fit for environments where port density, link stability, and lifecycle coverage carry real operational value. Ideal For Virtualization hosts needing multiple 10 GbE uplinks Data center racks standardizing on short-reach fiber Server clusters requiring compact high-density network expansion Storage and east-west traffic paths that benefit from 10 GbE links Why This Product 1 4 ports instead of a single uplink 2 SR connectivity for short-reach fiber runs 3 Pluggable module design for compatible Cisco systems 4 5-year term for longer lifecycle planning
