Abstract: A data reduction method, apparatus, and system are provided, and belong to the field of data processing. One example method includes: obtaining a first address; and updating, based on popularity of the first address, an entry corresponding to the first address in a hot data table, where popularity of a storage address in the hot data table is greater than popularity of a storage address in a first cache table, and the first cache table is used for data reduction.

Abstract: Embodiments of this disclosure provide for a storage device, a cache management method, and related apparatus. The storage device includes at least two levels of storages. The at least two levels of storages include a first-level storage and a second-level storage, and a speed of processing data by the first-level storage is higher than that of the second-level storage. The first-level storage includes at least a first storage area and a second storage area. Hotness values of data stored in the first storage area are within a first hotness value interval, hotness values of data stored in the second storage area are within a second hotness value interval, and the data in the first-level storage is swapped out at a granularity of one storage area based on the hotness values of the data.
