Dell Broadcom 57414 25GbE Dual-Port SFP28 rNDC Adapter

The Dell Broadcom 57414 25GbE Dual-Port SFP28 rNDC Adapter (part number 6VDPG) is a rack Network Daughter Card designed for Dell PowerEdge servers, providing two 25 Gigabit Ethernet ports via the SFP28 interface standard. Built on the Broadcom BCM57414 NetXtreme-E silicon, the adapter integrates directly into the server motherboard's rNDC slot, freeing standard PCIe slots for other expansion cards while delivering high-bandwidth, low-latency connectivity suited to demanding data center environments. The dual-port design allows for active-active or active-passive bonding configurations, supporting link aggregation and redundancy without additional hardware overhead.

The BCM57414 controller supports a comprehensive feature set including SR-IOV (Single Root I/O Virtualization) with up to 64 virtual functions per port, enabling efficient workload isolation in virtualized and containerized environments. Hardware offload capabilities encompass TCP, UDP, and IP checksum offload, large send offload (LSO), and receive side scaling (RSS), collectively reducing CPU overhead and improving throughput consistency under sustained load. The adapter supports RoCE (RDMA over Converged Ethernet) v1 and v2, making it suitable for latency-sensitive storage and inter-node cluster communication workloads that benefit from kernel-bypass networking.

As a native rNDC component validated for the Dell PowerEdge ecosystem, the 6VDPG integrates with Dell OpenManage systems management tooling and is compatible with the iDRAC management stack for out-of-band monitoring and configuration. The SFP28 port form factor supports both 25GbE direct-attach copper (DAC) cables and optical transceivers, providing deployment flexibility across top-of-rack switching fabrics. The adapter is a high-attach-rate component across the PowerEdge R-series and T-series server portfolio, reflecting its suitability as a standard connectivity baseline for enterprise server deployments.

Ideal for

• Virtualized server consolidation requiring SR-IOV-based network isolation for multiple virtual machines or containers on a single PowerEdge host
• Hyper-converged infrastructure nodes needing dedicated high-bandwidth storage and VM-migration network segments over a single dual-port adapter
• RoCE v2-enabled storage fabrics connecting PowerEdge compute nodes to NVMe-oF or iSCSI all-flash arrays with RDMA acceleration
• High-throughput database server deployments where hardware checksum and LSO offloads reduce CPU utilization on network I/O paths
• East-west data center traffic in scale-out web and application tiers requiring 25GbE uplinks with link aggregation for bandwidth and resilience
• Enterprise Kubernetes or OpenShift cluster nodes leveraging SR-IOV for direct pod-level network interface assignment and consistent low-latency performance
