HP Dual-Port Gigabit Ethernet Server Adapter

This HP network interface card adds two Gigabit RJ45 ports to a server or workstation through a PCIe x1 slot. It uses the Broadcom BCM5720-2P controller and supports IEEE 802.3ab Gigabit Ethernet over Category 5 cabling. Offload features such as Large Send, TCP segmentation and receive-side scaling reduce host CPU load. A low-profile bracket is included for small-form-factor chassis.

Suitable Servers and Limitations

The card fits Dell PowerEdge servers including R230, R330, R440, R540, R630, R640, R730, R740, R7415, R7425, FC430, FC630, FC640, C6320P and VRTX models. It runs on Windows Server, Hyper-V, VMware ESXi 5 through 8, vSphere, CentOS, Debian, Red Hat, Oracle Linux, Solaris, SUSE and Ubuntu. Builders needing fibre connectivity, 10 GbE speeds or a PCIe 3.0 or newer interface should look elsewhere.

BCM5720-2P Controller Decides Compatibility

The Broadcom BCM5720-2P MAC controller determines driver support and offload capabilities across the listed operating systems. It provides hardware checksum offload for TCP, UDP and IP plus RSS for multi-core scaling. Verify that your OS kernel or vendor driver includes support for this specific controller before purchase.

Questions about this item

Should I choose the single-port or dual-port version of this HP BCM5720 card?

The BCM5720-2P model supplied here is a dual-port adapter, giving you two RJ-45 connections from one PCIe x1 slot.

What does the 1000 megabits per second rating deliver inside an actual server?

It provides two independent Gigabit links compliant with IEEE 802.3ab, each capable of full-duplex 1000 Mb/s over standard Cat 5 cabling.

Which PCI Express standard does the x1 slot use, and what bandwidth ceiling does that impose?

The card works with PCIe v1.x and v2.x x1 slots, so each port is limited to the 2.5 or 5 GT/s lane speed of those generations.
