I am new to the VMware scene so please bear with me. I am looking at setting up some Windows 2012 Clusters for my File Server, SQL Server and Exchange Server. From my understanding, in order to setup Windows Server 2012 clusters the data must be stored on a RDM Disk. Should I (or maybe I need to) setup multiple LUNs / RDM Disks for each of the clusters that I wish to create?
For example, do I need to setup a LUN / RDM for my SQL cluster and then another seperate LUN / RDM disk for my File Server cluster or can I just create one large LUN / RDM disk for all of the clusters?
