Abstract
The present disclosure provides a data storage method, a data storage system and a requesting node. The data storage method includes the following steps. A register identifier and a register time are written into a target data table. The target data table is read to look for a register time record, such that an access right of the storage node is determined. A requesting node having the access right computes result data, and writes a usage identifier and the result data in the target data table. The target data table is read to judge the validity of the result data.
Claims50
A data storage method, applicable to a requesting node, the method comprising:
- writing a register identifier and a register time to a target data table;
- reading the target data table to look for a register time record to determine whether an access right to write into a storage node is obtained;
- computing result data by the requesting node obtaining the access right;
- writing a usage identifier and the result data into the target data table;
- and
- reading the target data table to judge validity of the result data.
A data storage system, comprising:
- at least one storage node, storing a target data table;
- and
- at least one requesting node, each of the requesting nodes writing a register identifier and a register time into the target data table,
- wherein when a current requesting node among the requesting nodes reads the target data table to look for a register time record to determine whether an access right to write into a storage node is obtained, the current requesting node obtaining the access right computes result data, writes a usage identifier and the result data into the target data table and reads the target data table to judge validity of the result data.
A requesting node, applicable to a data storage system, the requesting node comprising:
- an access right control unit, writing a register identifier and a register time into a target data table and reading the target data table to look for a register time record to determine whether an access right to write into a storage node is obtained;
- a computation processing unit, computing result data when the access right control unit determines that the access right is obtained and writing a usage identifier and the result data into the target data table;
- and
- a finalization confirming unit, reading the target data table to judge validity of the result data.
