Cisco DPX20/X10 Pluggable 4x10G-BP SR NIC Module | Enterprise Adapter — RD21-4X10GBPSR-3Y

Scale network attachment with four 10 GbE SR connections in a compact pluggable module. The Cisco DPX20/X10 Pluggable 4x10G-BP SR NIC Module is aimed at infrastructure teams that need dependable port density for server, storage, or aggregation workloads while keeping the hardware footprint controlled. The 10 GbE SR design is well suited to short-reach fiber deployments where predictable connectivity and clean rack integration matter. With four ports in one module, teams can consolidate adapter count, simplify cabling strategy, and maintain a consistent platform standard across refresh projects. This module is a practical choice when the goal is to add capacity without overbuilding. It gives procurement teams a clear reason to choose a Cisco-aligned part: known platform fit, multi-port density, and a 3-year coverage window that supports budgeted lifecycle management. For environments where every slot and cable run matters, that combination carries real operational value. Ideal For Add short-reach fiber connectivity to Cisco DPX20/X10 systems Support virtualization hosts that need multiple 10 GbE links Standardize adapter hardware across enterprise rack deployments Increase port density for aggregation or storage network segments Why This Product 1 Four 10 GbE SR ports versus lower-density adapters 2 Pluggable module format versus fixed NIC cards 3 Cisco platform alignment versus generic adapters 4 3-year coverage versus no-support purchases
