Each virtual disk is a volume on the array so that all data services of the array are available to it. VMware Virtual Volumes (vVols) are designed to leverage native capabilities of the FlashArray to the fullest.
Space consumed by the clones is proportional to the amount of changes that happen on the clones. What that means in the context of Oracle database cloning is that not only can these clones be created in a matter of minutes, irrespective of the source database size, they consume very little space when created. One of the leading features of the FlashArray is the Purity Snapshot technology. Irrespective of the size of the volume, one can create space-efficient snapshots and copies nearly instantaneously.
Clones of a production database are needed for various business reasons such as creating environments for development, testing, reporting, troubleshooting, etc. This article shows how we can leverage the capability of FlashArray™ snapshots to create clones of an Oracle database on a VMFS (Virtual Machine File System) datastore. Once a clone is created, the same process can be used to refresh the clone as and when needed. Cloning an Oracle database is one of the common tasks performed by the DBA operations team.
