High-Performance OCP NIC 3.0 25GbE Network Adapter for virtualized and RoCE fabrics with the BCM957504-N425G
The BCM957504-N425G is an OCP NIC 3.0 network adapter built on the Broadcom NetXtreme E-Series BCM57504 controller, designed for modern server platforms that require deterministic 25GbE uplinks and low-latency east-west traffic. With 4x 25GbE SFP28 ports supporting 10/25GbE profiles, it aligns cleanly with leaf-spine ToR designs and multi-tenant compute clusters where consistent throughput and predictable queue behavior matter.
As a PCIe Gen4 x16 OCP 3.0 module, the BCM957504-N425G provides the host bandwidth needed to sustain line-rate traffic while preserving CPU cycles through advanced offloads. Overlay acceleration for VXLAN, NVGRE, and Geneve, plus RSS, LRO/TSO, and PFC, reduces interrupt pressure and improves service stability under mixed microburst and east-west patterns. RoCE v1/v2 enables RDMA paths for storage and low-latency cluster messaging, while SR-IOV supports secure, high-density virtualization with direct I/O to VMs and containers. Boot and storage features such as PXE, iSCSI boot, iSCSI offload, and UEFI support help standardize bare-metal provisioning and stateless node designs.
Why Choose the BCM957504-N425G?
The BCM957504-N425G delivers a balanced density-to-performance profile for enterprise racks by combining 4-port 25GbE connectivity with PCIe Gen4 headroom and fabric-ready offloads. It is well suited to scale-out deployments where predictable latency, SR-IOV isolation, and RoCE acceleration are required without increasing host CPU overhead or operational complexity.
Broadcom engineering focuses on controller-level reliability, long-term platform interoperability, and security-aligned design. Hardware security capabilities such as Secure Boot, Silicon Root of Trust, and Secure Key Storage support modern data centre hardening requirements across Windows, Linux, and VMware ESX environments.
Key Applications:
- 25GbE leaf-spine server uplinks
- SR-IOV virtualized compute nodes
- RoCE-enabled storage traffic
- Low-latency east-west clusters
- Overlay network offload environments
