Supermicro AOC-S400G-B1C Std LP 1-port 400G QSFP56DD Broadcom BCM57600
The AOC-S400G-B1C is based on the Broadcom BCM57608 Ethernet Controller and offers a 1x400G-capable network interface that delivers high-performance networking while maintaining low power consumption and thermal efficiency. The BCM57608 series supports the fourth generation of RDMA over Converged Ethernet (RoCE) with hardware-based congestion control. This technology ensures low latency and simplifies RoCE deployment at scale. Furthermore, the BCM57608 features the TruFlow™ engine, a hardware acceleration engine with enhanced programmability. This engine allows for rapid implementation of new flow types, increasing virtual machine density and improving application performance. The BCM57608 supports industry-leading security features, including Broadcom’s HW Secure Boot (RoT) and Attestation support. These security measures enable the creation of secure server platforms. In summary, the BCM57608 series Ethernet Controllers are versatile and can be used in a wide range of hardware designs, including cloud and enterprise data center servers, AI and ML clusters, NVMe storage disaggregation, 5G Wireless RAN, Network Function Virtualization (NFV), mobile edge computing, and HPC environments.
