Abstract: Embodiments are provided for implementing a transparent conversion of common virtual storage requests to storage with limited access. Embodiments include providing a storage manager configured to perform address translation for requests, providing a data address translation (DAT) structure configured to connect a higher-level DAT table to a lower-level DAT table, and creating the DAT structure based on a request from a process. Embodiments also include responsive to receiving a storage request, performing a DAT fault process based on validating user credentials associated with an entry of the higher-level DAT table corresponding to the storage request, and responsive to the validation, updating the higher-level DAT table entry to allow access to the restricted-use portion of the common virtual storage, and otherwise, returning a DAT fault for the higher-level DAT table entry.
