Abstract
In write processing of a data set group to be written to be one or more data sets to be written, a storage system performs encoding processing including processing for generating a data model showing regularity of the data set group to be written and having one or more input values as an input and the data set group as an output. In the write processing, the storage system writes the data model generated in the encoding processing and associated with a key of the data set group to be written.
Claims15
A storage system comprising:
- a storage unit including at least one of a memory unit to be one or more memories and a PDEV (non-volatile physical storage device) unit to be one or more PDEVs;
- and
- a processor unit to be one or more processors connected to the storage unit,
- wherein, in write processing of a data set group to be written to be one or more data sets to be written, the processor unit
- performs encoding processing including processing for generating a data model showing regularity of the data set group to be written and having one or more input values as an input and the data set group as an output (W1), and
- writes the data model generated in the encoding processing and associated with a key of the data set group to be written to the storage unit (W2).

A storage control method comprising:
- in write processing of a data set group to be written to be one or more data sets to be written,
- performing encoding processing including processing for generating a data model showing regularity of the data set group to be written and having one or more input values as an input and the data set group as an output (W1);
- and
- writing the data model generated in the encoding processing and associated with a key of the data set group to be written (W2).

A computer program for causing a computer to execute:
- in write processing of a data set group to be written to be one or more data sets to be written,
- performing encoding processing including processing for generating a data model showing regularity of the data set group to be written and having one or more input values as an input and the data set group as an output (W1);
- and
- writing the data model generated in the encoding processing and associated with a key of the data set group to be written (W2).
