Abstract: A method for responding to access requests, the method may include (a) detecting, by a controller of a local storage system (LSS), a read pattern that (i) is associated with a requestor that is in communication with the LSS, and (ii) is estimated to comprise future read requests that are aimed to a remote part of a file system entity (FSE) that is stored at a remote storage system (RSS); wherein there is a latency difference between a remote latency associated with the remote part of the FSE and a LSS latency that is associated with the requestor; and (b) performing a prefetch process of remote sub-parts of the remote part of the FSE in order to support the read pattern while maintaining a desired latency.
