NetXtreme® E-Series Single-Port 25G OCP Mezzanine Adapter

Currently Viewing:

Based on Broadcom’s scalable 10/25/50/100G Ethernet controller architecture, NetXtreme®-E Series Open Compute Project (OCP) adapters can be used to build highly scalable, feature-rich RoCE networking solutions in servers for Enterprise and Cloud-scale applications, including Telco.

NetXtreme®-E 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 percent, 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 percent compared to software-only solutions. NetXtreme®-E Series controllers also support advanced networking technologies such as RoCE, SDN and NFV, to facilitate the management of data networks and to enable service provider solutions.


  • Standards-compliant 10/25G single-port SFP28 OCP adapter 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 RoCE, SDN, NFV and virtualization
  • Root of Trust security for enhanced network security protection from malicious attacks
  • TruManage™ enhances server manageability and security for data center deployments


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