BROADCOM 5720 DP 1GB NETWORK

The BROADCOM 5720 DP 1GB Network Interface Card is a high‑performance, dual‑port Ethernet solution designed for enterprise servers and data‑center environments. Built around the Broadcom BCM5720 LAN controller, this card delivers reliable Gigabit connectivity with support for both wired and wireless networking scenarios.

Key Technical Highlights

• Dual Ethernet Ports: Two RJ‑45 connectors provide simultaneous 10/100/1000 Mbps data transfer, enabling link aggregation or separate network segments.
• PCI Express Host Interface: The card plugs directly into a PCIe slot, ensuring low latency and high throughput for server workloads.
• Broadcom BCM5720 Controller: A proven, industry‑standard LAN controller known for robust driver support across major operating systems.
• Green Color Coding: The chassis is finished in a distinctive green hue, matching many Dell server aesthetics and simplifying visual identification during maintenance.
• IEEE 802.3 Ethernet Standard: Full compliance with the IEEE 802.3 specification guarantees interoperability with a wide range of network equipment.

Supported Operating Systems

The card is fully compatible with both Windows and Linux server distributions, making it suitable for mixed‑platform data centers. Official drivers are available from the Broadcom and Dell support portals, ensuring seamless integration into existing infrastructure.

Intended Use Cases

• Server Connectivity: Ideal for Dell PowerEdge servers (R220, R320, R420, R430, R520, R530, R620, R30, R720, R720xd, R730, R730XD, R820, R920) and T‑series workstations.
• High Availability: Dual ports support link aggregation (LACP) or failover configurations for critical applications.
• Data‑Center Networking: Designed to handle high traffic loads in virtualization environments, cloud platforms, and storage networks.

Installation & Compatibility

The card is an internal component, requiring a PCIe slot on the motherboard. It is fully compatible with Dell PowerVault DX6104 CSN, DX6104 SCN, and DX6104 SN storage arrays, as well as a broad range of server chassis. The green finish aligns with Dell’s standard color scheme for networking hardware, aiding in quick identification during system audits.

Performance Characteristics

• Data Transfer Rates: Supports 10 Mbps, 100 Mbps, and 1 Gbps speeds on each port.
• Cabling Technology: Utilizes 10/100/1000BaseT(X) for reliable wired connections.
• Network Protocols: Fully supports Ethernet networking protocols, including VLAN tagging and QoS features where enabled by the host operating system.

Physical Attributes

• Form Factor: Full‑height PCIe card suitable for standard server chassis.
• Color: Green, matching Dell’s internal networking hardware palette.
• Port Count: Two RJ‑45 Ethernet ports.

Driver & Firmware Support

The Broadcom BCM5720 controller benefits from regular firmware updates that enhance security, stability, and performance. Dell’s integration ensures that the card receives timely driver releases aligned with server BIOS and operating system updates.

Use in Virtualized Environments

With its dual‑port design, the card can be virtualized across multiple hypervisors (VMware ESXi, Microsoft Hyper‑V, KVM). Each port can be assigned to a different virtual machine or used for management traffic, providing isolation and redundancy.

Maintenance & Troubleshooting

• Diagnostics: Built‑in link status LEDs on each RJ‑45 connector provide real‑time visual feedback.
• Software Tools: Dell OpenManage and Broadcom’s NetXtreme software allow for port configuration, monitoring, and firmware upgrades.
• Common Issues: Typical problems involve driver mismatches or BIOS settings; these are resolved through updated firmware and correct PCIe slot selection.

Conclusion

The BROADCOM 5720 DP 1GB Network Interface Card delivers dependable, high‑throughput Ethernet connectivity for modern server deployments. Its dual ports, robust controller, and broad OS support make it a versatile choice for data‑center networking, virtualization, and enterprise workloads.
