VantageCore VMware supports both local storage and shared storage for single vNode cliques.
Local Storage
For performance and system up-time reasons, each Vantage system virtual disk should reside on a RAID-1 pair of physical disks. Common vSphere storage device configurations can use local storage or direct attached storage (for example, JBOD, RBOD).
Shared Storage for Single Node Cliques
If you are using external storage, such as a disk array, consider the performance and data redundancy implications. TPA vNodes have three or more database system pdisks, which will be deployed as separate VMware VMDK files.
Setting it to false may be useful when you have only a single large datastore. Determine the performance and data redundancy implications when using different RAID configurations, external versus internal storage.
