Windows 2003 Clustering

[ashley75]

this may be a easy question for some gurus in here, why do have to set up Virtual servers in the Clustering env? and what is the Virtual Server for?

I thought for Clustering env, we only need to have 2 nodes (2 machines) and that should do.

thanks,

The virtual servers are used to hold the services that will be running under the virtual name.

SQL server makes a good example.

When you install Clustering you setup a name. Let's assume that the hardware is named server1 and server2. When we install the cluster we have to setup a cluster name. This is nothing more than a virtual server. We'll call it cluster1.

We now wish to install SQL Server on the cluster. So we install SQL and setup a new virtual host called clsql1.

When you are setting up the virtual worlds it's recommended that each one be in it's own Cluster Resource Group. This way each one is independant and can be failed over from home node to the other independatly of each other.

Did I answer your question?
