Data prefetching method and related equipment

The invention provides a data prefetching method which comprises the steps that a first computing node generates a prefetching request according to a currently executed first read request, the prefetching request is used for obtaining prefetching data, the prefetching data are data related to data read by the first read request, the first computing node executes the prefetching request, and the first read request is used for reading the prefetching data; when the prefetched data is not hit at the first computing node, a target computing node is determined from at least one second computing node according to the prefetched data, the first computing node sends a second read request to the target computing node, and the second read request is used for indicating the target computing node to read the prefetched data; and the first computing node receives a prefetching result of the prefetched data sent by the target computing node. According to the method, pre-fetching from the storage system and pre-fetching fro
