SAP - Active Active Cluster on Windows Server 2003 ???

Dear All,

I am new to this Environment. My customer is asking to setup the Active Active Cluster for SAP. One will be having CI instance and One will be having DB Instance.

We are giving storage Space from SAN (excluding the Operating System C:\)

Can you please guide me about how to Go Ahead.

Thanks in Advance!
