Storage Checklist for Oracle Grid Infrastructure

Review the checklist for storage hardware and configuration requirements for Oracle Grid Infrastructure installation.

Table 1-6 Oracle Grid Infrastructure Storage Configuration Checks

Check	Task
Minimum disk space (local or shared) for Oracle Grid Infrastructure Software	At least 9.6 GB of space for the Oracle Grid Infrastructure for a cluster home (Grid home). Oracle recommends that you allocate 100 GB to allow additional space for patches. At least 10 GB for Oracle Database Enterprise Edition Allocate additional storage space in accordance with cluster configuration, as described in Oracle Clusterware Storage Space Requirements.
Select Oracle ASM Storage Options	During installation, based on the cluster configuration, you are asked to provide Oracle ASM storage paths for the Oracle Clusterware files. These path locations must be writable by the Oracle Grid Infrastructure installation owner (Grid user). These locations must be shared across all nodes of the cluster on Oracle ASM because the files in the Oracle ASM disk group created during installation must be available to all cluster member nodes. For Oracle Standalone Cluster deployment, shared storage, either Oracle ASM or shared file system, is locally mounted on each of the cluster nodes. Voting files are files that Oracle Clusterware uses to verify cluster node membership and status. Oracle Cluster Registry files (OCR) contain cluster and database configuration information for Oracle Clusterware.
Select Grid Infrastructure Management Repository (GIMR) Storage Option	For Oracle Standalone Cluster deployment, you can specify the same or separate Oracle ASM disk group for the GIMR. Note: Starting with Oracle Grid Infrastructure 19c, configuring GIMR is optional for Oracle Standalone Cluster deployments.
