Typical Storage Foundation cluster setup

From a high-level, if you install Storage Foundation with Oracle9i or Oracle 10g and create a database, the Storage Foundation cluster typically has the following characteristics:

• Nodes connected by at least two VCS private network links using 100 Base T or Gigabit. Ethernet controllers on each system.

  For two-node clusters, cross-over Ethernet cables are acceptable. For three or more nodes, Ethernet switches can be used. Symantec recommends Gigabit Ethernet using enterprise-class switches for the private links. In either case, use a minimum of two switches to provide necessary redundancy. If multiple links are present on a single switch, such as cases where three or four links are configured, a separate VLAN must exist for each link. The use of multiple links on a single hub is not supported.

  Nodes are connected to shared storage devices through Fibre Channel switch. Symantec does not support the use of shared SCSI with the Storage Foundation product. For a complete list of supported Fibre Channel storage devices, see the current hardware compatibility list on the Symantec Support Web site.

• Nodes running Veritas Cluster Server (VCS), Veritas Volume Manager with cluster features (CVM), Veritas File System with cluster features (CFS), and Storage Foundation for Oracle RAC agents and components, including I/O fencing.
• Oracle RAC database is configured on the shared storage that is available to each node. The shared storage could be cluster file system or raw volumes. All shared storage, including coordinator disks, must support SCSI-3 PR.
• VCS is configured to enable agents to direct and manage the resources required by Oracle RAC. This configuration is recommended but not required. The resources run in parallel on each system.
