Abstract
Embodiments of this application disclose a data access method and apparatus, a storage system, and a storage medium, and relate to the field of data storage technologies. In one example, a storage node in the storage system stores a data page, and may further receive a permission request of a compute node for the stored data page and allocate an access permission to the compute node.
Claims20
A data access method, comprises:
- in response to a permission request sent by a first compute node, allocating, by a storage node, a first access permission for a target data page to the first compute node, wherein the target data page is one of a plurality of data pages stored in the storage node, and the first compute node is one of a plurality of compute nodes comprised in a storage system;
- and
- sending, by the storage node, a permission feedback information and the target data page to the first compute node, wherein the permission feedback information indicates to allow the first compute node to access the target data page based on the first access permission.
A storage node, wherein the storage node comprises at least one processor and a memory, the memory stores a computer program, that when executed by the at least one processor, causes the storage node to perform operations comprising:
- allocating a first access permission for a target data page to a first compute node in response to a permission request sent by a first compute node, wherein the target data page is one of a plurality of data pages stored in the storage node, and the first compute node is one of a plurality of compute nodes comprised in a storage system;
- and
- sending permission feedback information and the target data page to the first compute node, wherein the permission feedback information indicates to allow the first compute node to access the target data page based on the first access permission.
A storage system, comprising:
- a plurality of compute nodes, wherein a first compute node of the plurality of compute nodes is configured to send a permission request;
- a plurality of storage nodes, wherein a first storage node of the storage nodes is configured to:
- allocate a first access permission for a target data page to the first compute node, wherein the target data page is one of a plurality of data pages stored in the storage node, and the first compute node is one of a plurality of compute nodes comprised in the storage system;
- send a permission feedback information and the target data page to the first compute node, wherein the permission feedback information indicates to allow the first compute node to access the target data page based on the first access permission.
