Abstract: To make it possible to prefetch data generated in another site. A file/object storage generates prefetch recommendation information regarding data stored in the file/object storage itself, on the basis of a data read request from a client or a file/object storage in another site, and transmits the prefetch recommendation information to the file/object storage in the other site. The file/object storage that has received the prefetch recommendation information generates a prefetch request on the basis of the prefetch recommendation information, acquires the data indicated by the prefetch recommendation information from the storage equipment in the site in which the data is stored, through the prefetch request, and stores the acquired data.

Abstract: In order to quickly recover a management information file, an Edge file storage stores user files and a management information file that manages management states of the user files in the Edge file storage. The Edge file storage manages operation logs indicating operation contents concerning user files accepted by nodes in association with the respective nodes. The Edge file storage extracts operation logs for a user file associated with a targeted management information file as a management information file stored in a failed node from the operation logs corresponding to the nodes. The Edge file storage aggregates operation logs that are extracted from the operation logs corresponding to the nodes and are used for the user file associated with the targeted management information file. The Edge file storage recovers the targeted management information file based on the aggregated operation log.
