Abstract
The present application relates to the field of SSD and discloses an SSD device with dynamic capacity cache acceleration, comprising: a memory comprising multiple storage subspaces; a cache comprising multiple cache subspaces; a cache allocator configured to calculate a cache execution configuration based on a cache configuration request for the storage subspace; a cache executor which selects a traversal range and a traversal order based on a cache execution configuration, a structured data for traverse history and a virtual index of a storage unit, and calculates minimum and maximum cost thresholds, the traversal range includes a set of cache units in a corresponding cache subspace and is divided into a plurality of pending windows; traverses the pending windows in the traversal order, calculates a cost function for each cache unit in the current pending window based on a structured state table, and selects a cache unit with a cost function that is less than the minimum cost threshold. This application configures and changes the cache subspace without resetting the device.
