Dell PCIe 25 Gigabit SFP28 x 2 Network Adapter

The Dell 540-BBUM is a PCI Express network adapter designed for servers that need stable, high-speed connectivity. Built around the Broadcom 57414 controller, it presents two SFP28 ports that each support 10 or 25 Gigabit Ethernet. This bandwidth allows a rack server to move large data sets quickly, keep latency low for time-sensitive workloads, and free up CPU cycles that might otherwise be spent handling network bottlenecks.

Administrators can install the card in an open PCIe slot and choose the right SFP28 transceivers or direct-attach cables for their environment. Once in place, the adapter enables fast virtual machine migration, accelerates backup windows, and supports demanding applications such as real-time analytics or high-volume storage replication. The dual-port layout also offers failover or link aggregation options for added resilience and throughput.

Because it follows Dell qualification guidelines, the 540-BBUM integrates smoothly with many PowerEdge platforms and aligns with management tools that data center teams already use. Whether you are refreshing a cluster, expanding a cloud deployment, or optimizing a high-performance computing node, this card provides a straightforward path to 25 GbE performance without a full system overhaul.

Highlights:

• Two SFP28 ports that operate at 10 GbE or 25 GbE
• PCI Express plug-in card for standard server slots
• Broadcom 57414 controller for reliable throughput and low latency
• Supports link aggregation and failover configurations
• Suits data center, virtualization, and high-performance computing workloads
