The PowerStore volume group feature enables an administrator to create a configuration that facilitates ease of management, efficient snapshots, and replication. For the baseline storage configuration, all four virtualized databases (DB1 to DB4) used the same design. The following table shows the baseline storage configuration for DB1. The database used was named ORABP22.
Table 6. Baseline storage configuration for DB1
Volume Group | Volume Name | Number of LUNs | VMware Datastore | Volume size (GB) | Notes |
orabp22-vm1-os | orabp22-vm1-os | 1 | orabp22-vm1-os-ds | 400 | Operating System |

A naming convention using VMn and DBn allowed the database administrators to increment the value to create volume groups for other databases. For example, the second copy of the database had a volume group name of ORABP22_VM2_DB2. Using this naming convention allowed the administration team to repurpose copies of the database quickly. Please note that each LUN was configured as a VMware datastore.
