Product information

Description

The Supermicro AOC-S25G-b2S is an internal PCIe network adapter that provides 25GbE connectivity for servers and workstations. Based on the Broadcom BCM57414 chipset, the card supports advanced offload and networking features while remaining backward compatible with 10GbE. The adapter follows PCIe 3.0 expansion card standards, is passively cooled and wired, and measures 140.2 × 60.9 × 120 mm. It is intended for system expansion and higher-performance wired network access in data center, cloud or enterprise environments.

Advantages

The AOC-S25G-b2S offers a feature-rich 25GbE solution with Broadcom BCM57414 capabilities such as VXLAN, NVGRE and RoCE for efficient virtualized and RDMA networking. TruFlow and NPAR (NIC Partitioning) provide flexible connectivity and traffic partitioning for varied workloads. Backward compatibility with 10GbE reduces migration complexity and cost when upgrading existing infrastructure. Passive cooling and a standard PCIe 3.0 host interface make the card simple to install in compatible server and workstation systems.

Suitable for (tasks / use cases)

  • Upgrading data center or cloud servers from 10GbE to 25GbE
  • High-throughput wired networking for virtualization and storage traffic
  • Enterprise servers and workstations requiring flexible NIC partitioning
  • Systems where passive cooling is preferred or required

Key specifications

  • Model: Supermicro AOC-S25G-b2S (MPN: AOC-S25G-B2S-O)
  • Chipset: Broadcom BCM57414
  • Interface: PCIe 3.0 (internal expansion card)
  • Connectivity: Wired, 25GbE (backward compatible with 10GbE)
  • Cooling: Passive
  • Dimensions: 140.2 × 60.9 × 120 mm
  • Weight: 0.0905 kg
  • Color: Green

How to use

Install the adapter into an available PCIe 3.0 x8/x16 slot following the host system manufacturer’s instructions and observe ESD precautions. Secure the card in the chassis, connect compatible 25GbE or 10GbE cabling to the network port, and power on the system. Install or update the operating system drivers and firmware provided by Supermicro or Broadcom to enable VXLAN, NVGRE, RoCE and other offload features. Configure network settings and NIC partitions (NPAR) as required by your environment.

Usage recommendations

Use the adapter in systems that meet PCIe 3.0 slot and physical clearance requirements. For optimal performance with RoCE and RDMA features, ensure network switches and cables support required protocols and low-latency configurations. Keep firmware and drivers up to date and monitor thermal and asset management data when deploying in dense rack environments.
