Add-on Card

The Supermicro AOC-S25G-m2S is a leading edge 25GbE controller. Based on the Mellanox ConnectX®-4 Lx EN chipset with features that such as VXLAN and NVGRE, it is backward compatible with 10GbE networks and addresses bandwidth demand from virtualized infrastructures in data center or cloud deployments. It supports the RoCE specification with CPU offload, delivering low-latency and high-performance over Ethernet networks. Supermicro® Asset Management and thermal detection give an extra layer of controller health management and peace of mind. The Supermicro AOC-S25G-m2S high performance 25GbE adapter solution is an excellent choice to enhance network connectivity in data centers and enterprise environments.
