摘要： Mechanisms are provided for importing pre-existing data into a storage system utilizing a current storage management system that is different from an original storage management system used to create the pre-existing data. One or more data storage devices are integrated into the storage system in-place without modification of the pre-existing data stored on the one or more data storage devices. Metadata for the pre-existing data is created based on a linear progression of data in the pre-existing data. Read access requests targeting the pre-existing data are executed using the created metadata. Write access requests targeting the pre-existing data are executed by redirecting the write access requests to a copy of the pre-existing data created in another storage location.

摘要： A method, system, and program key-controlled object-based memory protection are provided. A processing unit includes an authority check for controlling access by the processing unit to pages of memory according to whether a hardware protection key set currently loaded in an authority mask register allows access to the pages. In particular, each page of memory is assigned a page key number that indexes into the hardware protection key set. The currently loaded hardware protection key set specifies those page key numbers that are currently accessible to the processing unit for the execution context. Each hardware key within the hardware protection key set may be associated with a particular data object or group of data objects. Thus, effectively, the currently loaded hardware protection key set identifies which data objects or groups of data objects are currently accessible. Software keys are assigned to data objects and dynamically mapped to hardware protection key sets, such that when a module is called, the software keys assigned to that module are mapped to the hardware protection key set to be loaded for controlling current access to memory.

摘要： A method, system and computer program product for allocating real memory to virtual memory page sizes when all real memory is in use includes, in response to a page fault, selecting a page frame for a virtual page. In response to determining that said page does not represent a new page, a page is paged-in into said page frame and a repaging rate for a page size of the page is modified in a repaging rates data structure.
