Supermicro AOC-S25GC-m2S Dual-Port 25GbE SFP28 OCP 3.0 Mezzanine Adapter

The Supermicro AOC-S25GC-m2S is a dual-port 25 Gigabit Ethernet mezzanine adapter conforming to the OCP 3.0 specification. This card eliminates the need for dedicated PCIe slots by mounting directly into the mezzanine connector on OCP 3.0-compatible Supermicro server platforms, preserving valuable expansion capacity for storage controllers, accelerators, and additional network interfaces in dense deployment scenarios.

The adapter features two independent 25GbE ports via SFP28 optical transceivers, delivering 50 Gbps of aggregate bandwidth with low latency performance. It supports standard 25 Gigabit Ethernet protocols including IEEE 802.3by and is designed to operate across hyper-converged infrastructure, storage appliances, and high-performance compute clusters where network density and form factor efficiency directly impact TCO.

Deployed in multi-node environments, this mezzanine adapter enables seamless integration of 25GbE connectivity without architectural redesign, supporting both active-active and load-balancing configurations across dual ports for fault tolerance and throughput optimization.

Ideal for

• Hyper-converged infrastructure clusters requiring native 25GbE connectivity while preserving PCIe slots for NVMe controllers and storage adapters
• Software-defined storage deployments needing dual high-speed network paths for replication, cluster heartbeat, and data migration traffic isolation
• High-density compute pods in edge data centers where mezzanine mounting eliminates single points of failure in network fabric design
• Machine learning inference appliances requiring dedicated network interfaces separate from primary cluster interconnect
• Disaggregated storage architectures with performance-tier nodes needing independent out-of-band and in-band network segments
• Virtualized NFV platforms consolidating multiple tenant network functions on single hardware with deterministic network performance
