You can install Storage Foundation for Oracle Real Application Clusters (SF Oracle RAC) on virtual machines in VMware ESX environments. Each virtual machine within an ESX host is like a physical system with its own virtual operating components. Each VMware ESX host can contain multiple virtual machines. However, virtual machines that belong to the same SF Oracle RAC cluster must reside on different ESX hosts.
The virtual machines in the SF Oracle RAC clusters are connected by two virtual private links that are mapped onto the physicals links that connect the physical ESX hosts. You can configure each VMware ESX host to use local or shared storage. The configuration files of virtual machines can be located on shared or local storage. The database data files must be located on shared storage. All shared disks must support SCSI-3 Persistent Group Reservation (PGR). Therefore, the shared disks must be configured to use physical raw disk mapping (rdmp) compatibility mode. Since disks run in rdmp mode, you cannot migrate virtual machines using the vMotion feature. SF Oracle RAC supports paravirtual drivers for SCSI controllers.
To deploy SF Oracle RAC in VMware environments, you must:
