Embodiments of the present invention relate to a method and apparatus for adjusting throughput of a storage device. The method comprises setting input/output (I/O) delay time of the storage device to be threshold delay time, the threshold delay time being below initial I/O delay time of the storage device. The method further comprises obtaining measured throughput of the storage device, the measured throughput being associated with the threshold delay time. The method further comprises updating the I/O delay time based on a difference between the measured throughput and a target throughput of the storage device to update the measured throughput.

Method and apparatus for adjusting throughput of storage device

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.
