Supermicro Advanced I/O Modules (AIOM) is the latest form factor designed to provide a wide range of networking options as well as other I/O technologies. The AOC-A400G-B1CM is based on the Broadcom BCM57608 series Ethernet Controllers and is designed to lower data center total cost of ownership (TCO) by providing the industry's lowest power consumption for 400G NICs. The AOC-A400G-B1CM offers a 1x 400G-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.
