ABSTRACT:
Systems, methods and media for performing auto-migration of data among a plurality of memory devices are disclosed. In one embodiment, memory access of application program data is monitored for each of one or more application programs. The data may be stored in one or more of a plurality of memory storage devices, each with its own performance characteristics. Monitored access is evaluated to determine an optimal distribution of the application programs data, typically stored in files, among the plurality of memory storage devices. The evaluation takes into account service level requirements of each application program. Periodically, data may be automatically transferred from one memory storage device to another to achieve the determined optimal allocation among the available memory storage devices consistent with service level requirements.
