Abstract
In a computing system implementing a virtual memory system having real memory storage frames for storing virtual pages of data and an auxiliary storage system comprising auxiliary storage slots for storing copies of corresponding virtual pages, wherein I/O mechanisms are employed for effectuating transfer of data between auxiliary and real storage, a system and method for managing storage of unvirtualized dataset pages destined for auxiliary storage in a manner so to avoid I/O operations when assigning or moving VIO dataset data. The system and method is used to allow faster access to VIO data set pages by allowing that data to be kept in real storage.
