Microsoft Network Load Balancing

Network Load Balancing (NLB) is a clustering functionality that is implemented by Microsoft on Windows 2000 Server and Windows Server 2003 operating systems. Microsoft NLB clustering allows multiple servers running Microsoft Windows to be represented by one MAC and one IP address to provide transparent failover and load-balancing. The Dell Networking OS does not recognize server clusters by default; you must configure NLB functionality on a switch to support server clusters. The maximum NLB entry limit from 8 to 11 is increased and support for more CAM-ACL to increase.

To associate an IP address with a multicast MAC address in the switch when you configure multicast mode of network load balancing (NLB), use address resolution protocol (ARP).
