Abstract
When a load of a storage system is low, storing, in a manner of a small parity group, data received by the storage system, where the small parity group includes a data block and a parity block; and when a load of the storage system is high, storing, in a manner of a large parity group, data received by the storage system, where the large parity group includes a data block and a parity block, and a quantity of data blocks in the large parity group is greater than a quantity of data blocks in the small parity group.
Claims16
A data storage method, comprising:
- storing, in a manner of a small parity group, data received by the storage system, when a load of a storage system is low, wherein the small parity group comprises a data block and a parity block;
- and
- storing, in a manner of a large parity group, data received by the storage system, when a load of the storage system is high, wherein the large parity group comprises a data block and a parity block, and a quantity of data blocks in the large parity group is greater than a quantity of data blocks in the small parity group.
A data storage apparatus, comprising:
- a storage medium stores a computer program;
- and
- at least one processor, when execute the computer program, configured to:
- store a data received by the data storage apparatus, in a manner of a small parity group, when a load of the data storage apparatus is low, wherein the small parity group comprises a data block and a parity block;
- and
- store a data received by the data storage apparatus, in a manner of a large parity group, when a load of the data storage apparatus is high, wherein the large parity group comprises a data block and a parity block, and a quantity of data blocks in the large parity group is greater than a quantity of data blocks in the small parity group.
A storage system, comprising a plurality of storage devices, wherein when a load of the storage system is low, received data is chosen to be stored in the storage devices of the storage system in a manner of a small parity group, wherein the small parity group comprises a data block and a parity block;
- and
- when a load of the storage system is high, received data is chosen to be stored in the storage devices of the storage system in a manner of a large parity group, wherein the large parity group comprises a data block and a parity block, and a quantity of data blocks in the large parity group is greater than a quantity of data blocks in the small parity group.
