Product Overview

Product Overview:

This PCIe NetXtreme BCM5720 Dual-Port Gigabit network card is a dual-port 10/100/1000Mb/s x1 PCI Express Ethernet adapter that supports the IEEE802.3ab 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.
