Add-on Card

Advanced 25Gb Ethernet controller in Supermicro Advanced I/O Module (AIOM)

Supermicro® Advanced I/O Modules (AIOM) are designed to deliver a versatile range of networking options. The AOC-AH25G6-N2S2TM is a high-performance hybrid card powered by the NVIDIA CX6-LX controller, offering two 25GbE ports with advanced features such as VXLAN, NVGRE, RDMA, and more ensuring exceptional density, performance, and functionality.

Additionally, this card integrates the Intel E610-XT2 controller, providing two 10GBASE-T ports for enhanced connectivity. With advanced security features, including standards-based cryptographic security, hardware Root of Trust (RoT), and secure communication with management controllers, it strengthens Ethernet security while maintaining high-speed, reliable networking.
