NetXtreme® E-Series 200G Ethernet Controller

Currently Viewing:

Building upon the success of the widely deployed Broadcom NetXtreme E-Series architecture, the BCM57500 is a family of Ethernet Controllers optimized for Cloud and Enterprise data centers, providing high performance for Big Data and Machine Learning, web services, storage and database applications.
NetXtreme E-Series addresses the performance and service demands of megascale 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. TruTrust™ enables the industry’s most secure server platform with Broadcom’s Silicon Root of Trust and Secure Boot Loader. 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.
