Broadcom BCM957508-N2100G NetXtreme E-Series N2100G – network adapter – PCIe 4.0 x16 – 100 Gigabit QSFP56 x 2 (BCM957508-N2100G)

Based on Broadcoms scalable 10/25/40/50/100/ 200G Ethernet controller architecture, the N2100G 2x100G OCP 3.0 adapter is designed to build highly scalable, feature-rich networking solutions in servers for enterprise and cloud-scale networking and storage applications, including high-performance computing, telco, machine learning, storage disaggregation and data analytics.

The N2100G 2x100G OCP 3.0 adapter builds upon the success of the widely deployed Broadcom architecture by combining a high-bandwidth Ethernet controller with a unique set of highly optimized hardware acceleration engines to enhance network performance and improve server efficiency.

Driven by the growing need for higher server bandwidth and storage capacity to support new and emerging applications, enterprises, telcos and cloud providers are modernizing their data centers by adopting latest networking technologies, such as server virtualization and NVMe-oF. The resulting expansion in data volumes increases server-to-server traffic and CPU loads for networking tasks.

The N2100G 2x100G OCP 3.0 adapter can be configured as a 1x200G adapter with Port0 active as 200G and Port1 disabled. This can be configured at run time through firmware. For additional information see the Broadcom Ethernet network Adapter User Guide or contact a local Broadcom FAE.

With its market-leading hardware acceleration technologies, the N2100G 2x100G OCP 3.0 adapter addresses these performance and service demands of mega-scale data center networks with 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. These solutions also support advanced networking technologies such as RoCE, SDN and NFV, to facilitate the management of data networks and to enable service provider solutions.
