Sun Cluster Support for Oracle RAC enables you to use the storage management schemes for Oracle files that are listed in the following table. The table summarizes the types of Oracle files that each storage management scheme can store. Ensure that you choose a combination of storage management schemes that can store all types of Oracle files.
The meaning of each symbol in the table is as follows:
+ indicates that the storage management scheme can store the type of Oracle file.
- indicates that the storage management scheme cannot store the type of Oracle file.

Some types of files are not included in all releases of Oracle RAC. For information about which types of file are included in the release that you are using, see your Oracle documentation.
Oracle Clusterware disks such as Oracle cluster registry (OCR) and voting disks are supported on the following storage management schemes:
Solaris Volume Manager for Sun Cluster
Solaris Volume Manager for Sun Cluster is supported only with Oracle RAC. Solaris Volume Manager for Sun Cluster with Oracle Parallel Server is not supported.
Veritas Volume Manager (VxVM)
VxVM is supported only on the SPARC platform.
Hardware redundant array of independent disks (RAID) support
Sun StorageTekTM QFS shared file system with hardware RAID support or with Solaris Volume Manager for Sun Cluster
Qualified network-attached storage (NAS)
You can use the following storage management schemes for the Oracle RAC database:
Solaris Volume Manager for Sun Cluster
Solaris Volume Manager for Sun Cluster is supported only with Oracle RAC. Solaris Volume Manager for Sun Cluster with Oracle Parallel Server is not supported.
Veritas Volume Manager (VxVM) with the cluster feature
VxVM is supported only on the SPARC platform.
Hardware redundant array of independent disks (RAID) support
Sun StorageTek QFS shared file system with hardware RAID support or with Solaris Volume Manager for Sun Cluster
Qualified network-attached storage (NAS) devices
Oracle Automatic Storage Management (ASM)
You can install the Oracle binary files and Oracle configuration files on one of the following locations.
The local disks of each cluster node
A shared file system from the following list:
The Sun StorageTek QFS shared file system
The cluster file system
A file system on a qualified NAS device
Placing the Oracle binary files and Oracle configuration files on the individual cluster nodes enables you to upgrade the Oracle application later without shutting down the data service.
Some versions of Oracle require you to shut down the data service during an upgrade. To determine whether you can upgrade the Oracle application without shutting down the data service, see your Oracle documentation.
The disadvantage is that you then have several copies of the Oracle application binary files and Oracle configuration files to maintain and administer.
To simplify the maintenance of your Oracle installation, you can install the Oracle binary files and Oracle configuration files on a shared file system. The following shared file systems are supported:
The Sun StorageTek QFS shared file system
The cluster file system
If you use the cluster file system, decide which volume manager to use:
Solaris Volume Manager
VxVM without the cluster feature
VxVM is supported only on the SPARC platform.
A file system on a qualified NAS device
If you put the Oracle binary files and Oracle configuration files on a shared file system, you have only one copy to maintain and manage. However, you must shut down the data service in the entire cluster to upgrade the Oracle application. If a short period of downtime for upgrades is acceptable, place a single copy of the Oracle binary files and Oracle configuration files on a shared file system.
You can use the following storage management schemes for running Oracle RAC in a zone cluster, depending on the version of Oracle RAC you are running.
If you are using Oracle RAC 10g or Oracle RAC 11g, the following storage management schemes are supported:
Sun StorageTek QFS shared file system with Solaris Volume Manager
Sun StorageTek QFS shared file system with hardware RAID support
Solaris Volume Manager for Sun Cluster
If you are using Oracle RAC 9i, the following storage management schemes are supported:
Sun StorageTek QFS shared file system with Solaris Volume Manager
Sun StorageTek QFS shared file system with hardware RAID support
Solaris Volume Manager for Sun Cluster
