540-BDID Dell 25G PCIe 3.0 x8 Ethernet Network Card

High-Performance Low-Profile Dual-Port 25GbE PCIe Network Adapter with the 540-BDID

The 540-BDID is a Dell PCIe 3.0 x8 low-profile network adapter engineered to deliver dual-port 25GbE SFP28 connectivity in dense rack servers where predictable bandwidth and low latency are required. By placing 25GbE directly on a dedicated PCIe 3.0 lane group, the 540-BDID supports sustained east-west traffic while avoiding oversubscription common to shared I/O paths.

Architecturally, the 540-BDID aligns with modern leaf-spine data centres that standardise on 25GbE server uplinks to top-of-rack switching. The dual SFP28 ports enable active/active throughput scaling or segmented fabrics for production and storage traffic, supporting clean separation for iSCSI/NAS backends and overlay networks. The low-profile bracket allows the 540-BDID to fit 1U platforms and high-density virtualization nodes without compromising expansion planning, while the PCIe 3.0 x8 interface provides sufficient host bandwidth headroom for line-rate operation across both ports in typical enterprise workloads.

Why Choose the 540-BDID?

The 540-BDID delivers an efficient density-to-performance ratio by consolidating 2 x 25GbE links in a single PCIe slot, enabling scalable uplink designs without increasing server footprint. For enterprise deployments, the 540-BDID supports straightforward growth from 10GbE to 25GbE, improves network resiliency through dual-port redundancy, and integrates cleanly into standard cabling and transceiver strategies based on SFP28.

Dell designs the adapter for consistent operation in data centre environments, focusing on interoperability with validated server platforms, predictable thermal and power characteristics, and long lifecycle alignment with enterprise change-control and refresh cycles.

Key Applications:

• 25GbE server uplinks to top-of-rack switching
• Virtualization host networking
• Storage networking for iSCSI/NAS backends
• Overlay and micro-segmentation traffic
