Thanks for your kind reply.

After posting this question to many forums, finally you answered me 🙂

Let me make my question clear.

We have 1 Database server, which needs lot of resources. We want to take best use of resources. To reach to this end, we can deploy virtualization to use shared resources of other servers, and another solution is to implement SQL server clustering to share the load of server , among multiple servers. Although these 2 solutions are different, both of them can help use to reach to this purpose.Then which of them/? Another issue is "high availability" which can be reached using both solution. ...

Don't know which of them can help us....
