Some business environments may require a cluster setup that supports application high availability with differentiated configurations in the same cluster. For example, some applications in the cluster may need high availability with or without dependency on databases. And, some applications may require high availability with support for clustered databases. In such scenarios, you may want to consider a mixed configuration of Storage Foundation for Oracle RAC (SF Oracle RAC) and Storage Foundation Cluster File System High Availability (SFCFSHA) in your environment.

In mixed configurations, nodes with applications that require high availability can be configured to run SFCFSHA while nodes with applications that require clustered databases can be configured to run SF Oracle RAC.

This article introduces the configuration scenarios and the advantage of having mixed configurations.

The deployment scenarios are as follows:

  • Scenario 1: SF Oracle RAC is installed on all nodes in the cluster. Some of the nodes in the cluster are used to run applications in SFCFSHA environment.
  • Scenario2: SFCFSHA is installed on all nodes in the cluster. Some of the nodes in the cluster are used to run SF Oracle RAC.

Both configuration scenarios provide the following advantages:

  • Optimize and extend your cluster infrastructure to suit application needs in your environment.
  • Repurpose nodes in a cluster. A node running SFCFSHA can be reconfigured to run SF Oracle RAC.
  • Manage application dependencies.
  • Back up Oracle RAC database from SFCFSHA nodes in the cluster.
  • Enhanced storage availability with Cluster Volume Manager (CVM)  I/O shipping.
