Using the QLogic 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.
 For detailed information about teaming, see Chapter 2 Configuring Teaming
in Windows Server and Chapter 11 QLogic Teaming Services.
 For a description of VLANs, see Chapter 3 Virtual LANs in Windows.
