540-BCOQ BROADCOM BCM57412 10G PCIe 3.0 x8 Ethernet Network Card

High-Performance OCP 3.0 Dual-Port 10GbE SFP+ Network Adapter featuring Broadcom BCM57412 with the 540-BCOQ

The 540-BCOQ is an OCP 3.0 mezzanine NIC engineered for rack server I/O expansion where predictable 10GbE uplinks and low CPU overhead are required. Built on the Broadcom BCM57412 Ethernet controller, the 540-BCOQ delivers 2 x 10GbE SFP+ connectivity and targets virtualization hosts and storage-oriented nodes that need consistent east-west throughput and clean separation of traffic classes.

Using an OCP 3.0 host interface with a PCIe 3.0 x8 electrical connection, the 540-BCOQ aligns with modern dense server designs that prioritize front-to-back airflow and serviceability while preserving PCIe slots for accelerators and NVMe expansion. Hardware offloads for TCP/IP, checksum, and iSCSI reduce host CPU cycles during heavy network and storage traffic, improving consolidation ratios in VM-dense environments. SR-IOV provides segmented networking with direct VM access patterns, while PXE support streamlines bare-metal provisioning across mixed Linux, Windows, and VMware estates.

Why Choose the 540-BCOQ?

The 540-BCOQ is a pragmatic choice for enterprises standardizing on OCP 3.0 mezzanine connectivity to maximize density-to-performance in 1U/2U platforms. By combining dual 10GbE SFP+ ports, mature virtualization features, and proven offload capabilities, the 540-BCOQ supports scalable designs for ToR access networks and software-defined storage nodes without adding DPU complexity or RDMA dependencies.

Broadcom designs Ethernet controllers with a focus on interoperability, driver stability, and lifecycle consistency, enabling reliable operation in production data centres that demand controlled firmware baselines and predictable behavior under sustained load.

Key Applications:

• Virtualization hosts with SR-IOV network segmentation
• iSCSI storage networking for SDS nodes
• OCP 3.0 10GbE uplinks to ToR access switches
• PXE-based provisioning and deployment pipelines
