Jes,
My apologies, the limits cited are for each Delphix engine. Of course, it is possible to have more than one Delphix engine, and many companies do so.
I work with one company with more than 50 Delphix engines, managing more than 500 source databases and over 6000 virtual databases.
Delphix professional services has a solutions architecture team that is expert in sizing Delphix engines based on past, current, and anticipated database I/O workloads.
Outsourcing, or migrating to another data center or IaaS, are prime use cases for the foundation Delphix data virtualization capabilities, as well as the additional data transformations of data masking, cross-platform conversion, and database upgrades.
The foundation data virtualization capability minimizes storage and time during provision and refresh, and the self-service capabilities in the hands of development and testing teams streamlines processes even faster, thus accelerating infrastructure utilization and enabling agile development, DevOps, and continuous delivery.
Beyond that, data masking in particular is a transformation that is critical for the elimination of any security risks in any outsourcing scenario or cloud migration.
Cross-platform conversion on Oracle is a method to escape from legacy UNIX platforms to cloud-based Linux x86 platforms.
And, if desired, automated database upgrades are another transformation to increase DBA team efficiency in provisioning or refreshing non-production databases.
Please let us know if more information would be helpful?
Thanks!
