SuperMicro AOC-S25G-B2S BCM57414 Dual Port SFP+ 25GbE Low Profile Network Adapter双口万兆光纤网卡
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.
