About the Broadcom BCM5720 Dual-Port 1GbE PCIe Ethernet Controller

The Broadcom BCM5720-KFB is a proven dual-port 1GbE Ethernet controller purpose-built for mission-critical server environments across Dell PowerEdge, HPE ProLiant, and Supermicro platforms. With integrated iSCSI and FCoE offload engines, this PCIe 2.0 x4 adapter reduces CPU overhead during storage-intensive workloads while maintaining 2 Gbps full-duplex throughput per port. SR-IOV support enables efficient virtual machine networking in consolidated data center deployments, making it ideal for virtualized storage, cloud infrastructure, and I/O-constrained environments where network isolation and performance are essential.

Technical Capabilities:

  • Dual RJ-45 1GbE ports with hardware TCP/IP and UDP acceleration
  • SR-IOV virtualization with up to 8 virtual functions per port for flexible VM allocation
  • Native iSCSI and FCoE offload reduces hypervisor CPU utilization
  • Low power consumption (<4W per port) suitable for high-density rack deployments
  • Embedded IPMI/iDRAC/iLO management integration for seamless enterprise integration

Whether scaling SAN connectivity, deploying converged infrastructure, or optimizing virtualized workloads, the BCM5720-KFB delivers reliable, field-proven performance.
