NetXtreme® C-Series Dual-Port 25G Cloud-Optimized PCIe Ethernet Adapter

Currently Viewing:

Based on Broadcom’s scalable 25/50G Ethernet controller architecture, NetXtreme® C-Series PCIe Ethernet NIC solutions can be used to build highly-scalable, feature-rich networking solutions in servers for cloud-scale applications.
NetXtreme® C-Series addresses the performance and service demands of mega-scale data center networks for high throughput and advanced flow processing. Features such as TruFlow™ increase VM density up to 50%, freeing more CPU cycles for additional virtual machines. On-chip tunneling protocol processing for Geneve, VXLAN and NVGRE provides up to a 5X throughput increase while lowering CPU utilization up to 90%, compared to software-only solutions. NetXtreme® C-Series controllers also support advanced networking technologies such as SDN and NFV, to facilitate the management of cloud networks and to enable service provider solutions.


  • Standards-compliant 10/25G dual-port SFP28 PCIe NIC with 30MPPS full-duplex throughput
  • TruFlow™ engine for intelligent flow processing to increase server VM density and accelerate vSwitch processing
  • New end-to-end congestion avoidance and management to anticipate and eliminate congestion before it happens
  • Support for advanced networking technologies including SDN, NFV and virtualization
  • TruManage™ enhances server manageability and security for data center deployments


  • Network Function Virtualization (NFV)
  • Software Defined Networking (SDN)
  • Enterprise and Cloud Servers
