NetXtreme® C-Series Single Port 50G Cloud-Optimized OCP Mezzanine Board

Currently Viewing:

Based on Broadcom’s scalable 25/50G Ethernet controller architecture, NetXtreme® C-Series OCP mezzanine board 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.
