High-Level View of Storage Foundation for Oracle RAC

This section introduces a high-level view of VERITAS Storage Foundation for Oracle RAC and tasks to install SFRAC. If you install SFRAC with Oracle9i and create a database, the cluster 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 maximum performance, VERITAS recommends the use of switches over hubs. In either case, use a minimum of two switches or hubs to provide necessary redundancy.
• Nodes connected to shared storage devices via Fibre Channel switch. VERITAS does not support the use of shared SCSI with this product. For a complete list of supported Fibre Channel storage devices, see the current hardware compatibility list on the VERITAS Support Web site: http://support.veritas.com.
• 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 software that resides either on the shared storage accessible to all nodes or locally on each node.
• Oracle RAC database configured on the shared storage (cluster file system or raw volumes) is available to each node.
• Resources required by Oracle RAC; these resources runs in parallel on each node.
