AOC-S25G-b2S - Supermicro

Supermicro

The Supermicro AOC-S25G-b2S is one of the most feature rich and versatile 25GbE controllers in the market. Based on the Broadcom® BCM57414 chipset with features such as VXLAN, NVGRE, and RoCE it is backward compatible with 10GbE network and the most cost effective upgrade from 10GbE to 25GbE in data center or cloud deployments. The unique features including TruFlow and NPAR (NIC Partitioning) technology provide flexible connectivity for different networking requirements. SupermicroR Asset Management and thermal detection give the extra layer of controller health management and a peace of mind. The Supermicro AOC-S25G-b2S is one of the most versatile 25GbE controllers in the market and an excellent choice to enhance network connectivity in data centers and enterprise environments.
