  • Dynamic storage tiering
    Patent number: 10120575
    Abstract: Embodiments of the present disclosure provide a method and apparatus for dynamic storage tiering by calculating a density of data according to a temperature of the data, and making the density of data with a higher temperature smaller; obtaining density threshold of each of the tiers, wherein the density threshold of an upper tier is smaller than that of a lower tier; comparing the density of the data with the density threshold of each of the tiers to determine which tier the data should be moved to; and moving the data to the determined tier. Embodiments of the present invention may be used to provide a dynamic storage tiering scheme with higher flexibility and scalability.
