Abstract
A data access method includes a target storage node that determines at least one data access policy input or selected by a user on a management platform. The target storage node receives a first write data stream from a request client, where the first write data stream indicates a first tape, first data to be written into the first tape, and first tape space required by the first data, the first tape space belongs to a same data partition. The target storage node writes the first data into the first tape according to the at least one data access policy using a first tape drive in at least one tape drive.
Claims20
A method comprising:
- determining, by a target storage node, at least one data access policy entered or selected by a user on a management platform;
- receiving, by the target storage node, a first write data stream from a request client, wherein the first write data stream indicates a first tape, first data to be written into the first tape, and first tape space required by the first data, and wherein the first tape space is assigned to a same data partition allocated to at least one storage node in a storage node cluster to which the target storage node belongs;
- and
- writing, by the target storage node, the first data into the first tape according to the at least one data access policy using a first tape drive in at least one tape drive associated with the target storage node.
A computing device cluster, comprising:
- at least one computing device, comprising:
- a memory configured to store instructions;
- and
- one or more processors coupled to the memory and configured to execute the instructions to cause the computing device cluster to:
- determine at least one data access policy entered or selected by a user on a management platform;
- receive a first write data stream from a request client, wherein the first write data stream indicates a first tape, first data to be written into the first tape, and first tape space required by the first data, and wherein the first tape space is assigned to a data partition allocated to at least one storage node in a storage node cluster to which a target storage node belongs;
- and
- write the first data into the first tape according to the at least one data access policy using a first tape drive associated with the target storage node.
A computer program product comprising instructions that are stored on a non-transitory computer-readable medium and that, when executed by one or more processors, cause a computing device cluster to:
- determine at least one data access policy entered or selected by a user on a management platform;
- receive a first write data stream from a request client, wherein the first write data stream indicates a first tape, first data to be written into the first tape, and first tape space required by the first data, and wherein the first tape space is assigned to a data partition allocated to at least one storage node in a storage node cluster to which a target storage node belongs;
- and
- write the first data into the first tape according to the at least one data access policy using a first tape drive associated with the target storage node.
