Based on Broadcom’s scalable 400G Ethernet controller architecture, the BCM57608 400G NIC adapters are designed to build large scale, feature rich networking solutions in servers for AI/ML, cloud, high-performance computing, and storage applications.

The BCM57608 NIC adapters build 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 adapters support 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 the complexity of RoCE deployment at
scale.

The BCM57608 400G NIC adapters address the performance requirements of mega-scale data center networks with high throughput and advanced
flow processing offloads. Features such as True Flow 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).
