Cisco DPX20/X10 4x10G NIC Module, 1-Year | Enterprise Network Adapter — RD21-4X10GNIC-1Y

Keep access and aggregation paths moving with the Cisco DPX20/X10 Pluggable 4x10G NIC Module. Designed for DPX20 and X10 platforms, this module delivers four 10 Gigabit Ethernet connections in a compact pluggable format. It is well suited to infrastructure teams that need to add bandwidth without overcommitting to a larger or more expensive architecture. The 4x10G layout gives architects flexibility when segmenting traffic across server, storage, or uplink roles. In practical terms, that can mean cleaner port planning, easier capacity allocation, and fewer compromises when balancing performance against rack density. The pluggable design also supports faster replacement and simpler maintenance than fixed-interface alternatives. With a 1-year support term, this SKU fits focused refreshes, project-based rollouts, and environments where the platform decision is already settled. It is a measured choice for buyers who want Cisco compatibility and a precise port mix without paying for capacity they will not use.
