Building a Windows NLB cluster for CAS servers
High availability for servers running the CAS role is achieved using Network Load Balancing (NLB) and CAS arrays. While it is recommended that you use a Hardware Network Load Balancing (HLB) solution, Windows NLB is still supported and may be appropriate for small or medium sized organizations. In this recipe, you'll learn how to create a Windows NLB cluster using PowerShell for servers running Windows Server 2008 R2 and Windows Server 2012.
Getting ready
For this example, you'll need to run some commands against each of your CAS servers that will be a part of the NLB cluster. You must run these commands from at least one of the CAS servers, and each server in the cluster will need to be running Windows Server 2008 R2 or Windows Server 2012 for this to work.
To complete the steps in this recipe, you can use a standard Windows PowerShell console or use the Exchange Management Shell from the server.
