DATA STORAGE MANAGEMENT BASED ON INDICATED STORAGE LEVELS AND OTHER CRITERIA FOR MULTILEVEL STORAGE SYSTEMS

摘要

Data can be stored based on one or more indications and one or more other storage criteria. The indications can effectively indicate or identify a storage level for storing data in a multi-storage system. The indications, however, need not be the only basis for storing the data object in a multi-storage system as one or more other storage criteria can also be considered. As a result, the indication can be used to effectively influence data storage but other storage criteria can be used as well to prevent adverse effects caused by undue influence and to ensure the overall efficiency of the system. Also, the one or more other storage criteria can be evaluated or reevaluated on a continual basis.

1. A method, implemented at least partly by a device, for managing storage of data in multiple storages of a multi-storage system, wherein the multiple storages are respectively associated with multiple storage levels, and wherein each one of the storage levels is associated with one or more storages of the multiple storage system, and wherein the method comprises:
obtaining at least one indication indicative of at least one storage level for storing at least one data object in the multi-storage system; determining based on one or more storage criteria whether to allow or continue to allow at least one data object to be stored in at least one storage of the at least one storage level as indicated by the at least one indication; and allowing the at least one data object to be stored or continued to be stored in the at least one storage level indicated by the at least one indication when the determining determines to allow or continue to allow the at least one data object to be stored in at least one storage of the at least one storage level.
