Abstract: A data prefetching method and apparatus, and related storage device are provided. Data samples are collected. An AI chip trains the data samples to obtain a prefetching model. The AI chip then sends the prefetching model to a processor. The processor reads to-be-read data into a cache based on the prefetching model to reduce the computing burden of the processor.

Abstract: Embodiments of this application provide a method for detecting ransomware, a related system, and a storage medium. The method includes: obtaining a partial feature of a target file based on preset data in the target file, where the partial feature includes a partial incremental entropy and/or partial histogram statistical data; determining, based on the partial feature of the target file, whether the target file is an encrypted file; and determining, if the target file is the encrypted file, that the target file is attacked by the ransomware. The method can increase file detection efficiency and accuracy.

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.

Abstract: This disclosure provides an access request processing method, a storage device, and a storage system. In embodiments of this disclosure, a first storage device receives an artificial intelligence (AI) model from a second storage device, wherein the AI model is obtained by the second storage device through training based on historical input output (IO) requests in historical running processes. The first storage device obtains a prediction result of the AI model based on an access request received by the first storage device.
