Hello-
In a current Delphix Dynamic Data Platform deployment on Azure, the image automatically deploys a root filesystem device of 128GB, of which ~12GB is used initially. However, the total size allocation for the Delphix Engine is determined by the environments and objects you wish to ingest, which is discussed in our documentation at:
https://docs.delphix.com/docs/system-installation-configuration-and-management/installation-and-init...If you require additional information or assistance in sizing guidelines, we would recommend engaging your account team or Solutions Architecture team, which we can certainly facilitate if needed.
