Document Type and Number:
WIPO Patent Application WO/2023/236629
Kind Code:
A1
Abstract:
The embodiments of the present application belong to the technical field of data storage. Disclosed are a data access method and apparatus, and a storage system and a storage medium. In the embodiments of the present application, storage nodes in the storage system not only store data pages, but can also receive a permission request from computing nodes regarding the stored data pages, and can allocate access permissions to the computing nodes. That is, in the embodiments of the present application, a permission management function of the data pages is unloaded from the computing nodes to the storage nodes that store the data pages, such that even if a certain computing node fails, there is no need to reselect a main computing node, and the other computing nodes can still apply for access permissions by means of the storage nodes in the storage system, thereby improving the availability of the system.
