Based on Broadcom’s scalable 400G Ethernet controller architecture, the N1400GD 1x400G OCP 3.0 adapter is designed to build highly scalable, feature-rich networking solutions in servers for AI/ML, cloud, high-performance computing and storage applications.

The N1400GD 1x400G 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.

The adapter supports fourth-generation, standards-based RDMA over Converged Ethernet (RoCE) with hardware-based congestion control. Broadcom’s RoCE congestion control delivers the lowest latency in real-life scenarios and dramatically reduces RoCE complexity deployment at scale.

With its market-leading hardware acceleration technologies, the N1400GD 1x400G 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 virtual machine density by freeing up CPU cycles. The adapter supports technology-leading security enabling the industry's most secure server platform with secure boot and attestation anchored in Broadcom's silicon Root-of-Trust (RoT).
