Similarly, an SA has the option of using HP Integrity Network Adapter Teaming to increase server network performance by load balancing server traffic across fault tolerant network adapter resources. Deploying load - HP Rx2620-2 | Windows Integrity Network Adapter Teaming White Paper - Page 13
is a result of HP's desire to provide HP Integrity server customers with a consistent and complete suite of advanced server networking technology solutions. In addition, the HP Integrity Network Adapter Teaming product provides solutions to many server networking problems that are not solved - HP Rx2620-2 | Windows Integrity Network Adapter Teaming White Paper - Page 14

In addition, teaming supports load balancing without requiring any kind of special configuration or feature support on the network devices (for example, clients) with which the team is communicating.

Within Windows Server 2003 and Windows Server 2008, there are four layers that are important to understand when discussing HP Integrity Network Adapter Teaming: the Miniport layer, Intermediate layer, NDIS layer, and Protocol layer. • Miniport layer The network adapter driver resides at the - HP Rx2620-2 | Windows Integrity Network Adapter Teaming White Paper - Page 30

HP Network Configuration Utility The configuration GUI is called the HP Network Configuration Utility - HP Rx2620-2 | Windows Integrity Network Adapter Teaming White Paper - Page 31
of HP Integrity Network Adapter Teaming. In NFT mode, two to eight ports are teamed together to operate as a single virtual network port. However, only one network port, the Primary port, is used for both transmit and receive communication with the server.
