Functional Description
Broadcom NetXtreme Gigabit Ethernet adapters connect a PCI Express™ compliant system to a Gigabit
Ethernet network. Broadcom NetXtreme Gigabit Ethernet adapters incorporate a technology that transfers data
at a maximum rate of 1 gigabit per second—10 times the rate of Fast Ethernet adapters.
Using the Broadcom teaming software, you can split your network into virtual LANs (VLANs) as well as group
multiple network adapters together into teams to provide network load balancing and fault tolerance
functionality. See Teaming and Broadcom Gigabit Ethernet Teaming Services for detailed information about
teaming. See Virtual LANs for a description of VLANs. See Configuring Teaming for instructions on configuring
teaming and creating VLANs on Windows operating systems.
