The NetXtreme BCM5720-2P is a dual-port 10/100/1000 Mb/s x1 PCI Express (PCIe) Ethernet adapter that supports the IEEE 802.3ab standard over Category 5 twisted-pair cable. The adapter card supports offload technologies including Large Send, TCP segmentation, and TCP/UDP/IP checksum, and receive-side scaling (RSS) that deliver optimal network throughput, lower host processor utilization and as a result improve system overall performance. The adapter card comes in small form factor that is suitable for both low-profile and standard chassis.

The BCM5720-2P NIC supports the following features:

• Dual-port Gigabit Ethernet Server adapter

• IEEE 802.3ab 10/100/1000 Mb/s Gigabit Ethernet-compliant
