Advanced 4-port 25GbE Ethernet Controller

The Supermicro® AOC-M25G-m4S is one of the most feature rich 25GbE controllers in the market. With 4-ports of 25GbE SFP28 connectivity in small form factor SIOM, it provides unparalleled density, performance, and functionality. Based on the Mellanox® ConnectX-4 Lx EN with features such as VXLAN, NVGRE and RoCE; it provides flexible connectivity for different networking requirements. It is also compatible with 10GbE networks and is the most cost effective upgrade from 10GbE to 25GbE in Data Center and Cloud deployments.


To order, contact your distributor. This product is only available through Supermicro.
