Supermicro 25GbE Dual-Port SFP28 OCP 3.0 NIC AOC-A25G-b2SM

The Supermicro AOC-A25G-b2SM is a dual-port 25 Gigabit Ethernet network adapter implementing the OCP 3.0 (Open Compute Project) form factor for seamless integration into OCP-compliant server architectures. Each SFP28 port operates at 25 Gbps, delivering 50 Gbps aggregate throughput for north-south and east-west datacenter traffic patterns. The adapter leverages PCIe connectivity to host systems and supports standard Ethernet protocols across modern Linux, Windows Server, and hypervisor environments.

Designed for high-density datacenter deployments, this dual-port NIC eliminates the need for discrete add-in card slots in space-constrained environments while maintaining full protocol compliance and performance characteristics. The OCP 3.0 standard ensures compatibility across an expanding ecosystem of certified server platforms and enables modular network fabric scaling.

Targeted at cloud infrastructure operators, HPC clusters, and enterprise datacenter operators requiring deterministic, low-latency networking at scale, the AOC-A25G-b2SM facilitates bandwidth-intensive workloads including virtual machine migration, distributed storage replication, and high-frequency trading applications.

Ideal for

• Hyperscale datacenter east-west traffic for VM-to-VM and container communication
• Distributed storage fabrics requiring high-throughput, low-latency interconnects
• High-performance computing (HPC) cluster node networking
• Live migration and replication workloads across geographically dispersed infrastructure
• Financial services platforms demanding deterministic network latency and throughput
• Content delivery and media streaming infrastructure with multi-gigabit per-second requirements
