Dell Broadcom 5720 Dual-Port Gigabit Adapter

This low-profile PCI-Express network card adds two RJ45 Gigabit Ethernet ports to compatible Dell PowerEdge servers. It targets administrators who need redundant copper links for management or workload traffic in 1U or space-constrained chassis.

Dual 1 Gbps RJ45 ports on a single PCI-Express slot

The Broadcom BCM5720 controller delivers two independent Gigabit Ethernet connections from one low-profile bracket. This port density is the deciding factor when a server has limited expansion slots but requires separate networks for storage, backup or out-of-band management.

Sustained line-rate throughput on both ports

The BCM5720 processor maintains full 1 Gbps transmit and receive on each port under continuous load without throttling. Hardware offloads for checksum, segmentation and VLAN tagging keep CPU utilisation low during prolonged backup windows or replication jobs.

Questions about this item

What does the 1 Gbps dual-port rating mean once the card is installed in a server?

Each of the two RJ45 ports delivers up to 1 Gbps full-duplex throughput, giving two independent gigabit links for separate networks or link aggregation.

The card uses a PCI-Express interface — what generation and lane width does it actually run at?

It connects through a PCI-Express slot; the exact generation and lane count are determined by the server's backplane and the BCM5720 controller.

Will this low-profile bracket fit a standard 1U chassis such as a PowerEdge R620?

Yes, the low-profile form factor is designed for 1U and 2U PowerEdge servers including the R620, R630, R720 and R720xd.
