What is the purpose of NLB?
By combining two or more computers that are running applications into a single virtual cluster, NLB provides reliability and performance for web servers and other mission-critical servers. The servers in an NLB cluster are called hosts, and each host runs a separate copy of the server applications.
How do I connect to a cluster using NLB?
In Server Manager, select Administrative tools and then select Network Load Balancing Manager. If NLB Manager does not already list the cluster, connect to the cluster. Right-click the cluster and select Cluster Properties. On the Cluster Parameters tab, select Unicast or Multicast in Cluster operation mode.
What is Network Load Balancing (NLB)?
The Network Load Balancing (NLB) feature distributes traffic across several servers by using the TCP/IP networking protocol. By combining two or more computers that are running applications into a single virtual cluster, NLB provides reliability and performance for web servers and other mission-critical servers.
How do I install and manage NLB?
You can install NLB by using either Server Manager or the Windows PowerShell commands for NLB. Optionally you can install the Network Load Balancing Tools to manage a local or remote NLB cluster. The tools include Network Load Balancing Manager and the NLB Windows PowerShell commands. Installation with Server Manager
What is scalability for NLB clusters?
For NLB clusters, scalability is the ability to incrementally add one or more systems to an existing cluster when the overall load of the cluster exceeds its capabilities. To support scalability, you can do the following with NLB: Balance load requests across the NLB cluster for individual TCP/IP services.
What are the different modes of NLB?
NLB can operate in any of three modes: unicast, multicast, and multicast that uses Internet Group Membership Protocol (IGMP multicast). Each of these modes has different requirements and places different demands on the network infrastructure.
