540-BBUO Dell 10G PCIe 3.0 x8 Ethernet Network Card

Enterprise PCIe 10GbE Base-T Network Adapter delivering dual-port copper connectivity with the 540-BBUO

The 540-BBUO is a Dell OEM full-height PCIe 3.0 x8 add-in NIC designed to provide deterministic 10GbE Base-T uplinks for rack servers and dense virtualization nodes where copper cabling and standard RJ45 switching are operational requirements. Built on the Broadcom BCM57416 controller, the 540-BBUO targets low-overhead network transport for modern x86 CPU platforms, aligning with NUMA-aware I/O placement and consistent packet handling under multi-VM and containerized workloads.

By attaching through PCIe 3.0 x8, the 540-BBUO supports high aggregate throughput while preserving expansion capacity for NVMe storage or accelerator cards. Dual 10GBASE-T ports enable active/standby or active/active teaming for redundancy and traffic segmentation, and hardware offloads such as TCP/IP offload, LSO, and checksum offload help reduce CPU cycles spent on networking. PXE and iSCSI boot capabilities make the 540-BBUO suitable for stateless provisioning and iSCSI environments where SAN boot and TCP/IP efficiency are critical to host density.

Why Choose the 540-BBUO?

The 540-BBUO offers an efficient density-to-performance profile for enterprises standardizing on 10GbE copper, enabling resilient dual-uplink designs without consuming multiple PCIe slots. As a PCIe add-in card, the 540-BBUO scales cleanly across server fleets, supports consistent deployment images via PXE, and strengthens availability through link redundancy for virtualization and application tiers.

Dell engineering emphasizes platform compatibility, lifecycle management, and predictable behavior under sustained load, aligning the adapter with current data centre standards for serviceability and controlled change management in production environments.

Key Applications:

• Virtualization hosts and hypervisors
• Application servers requiring redundant LAN uplinks
• iSCSI SAN boot environments
• Converged traffic for east-west and north-south flows
