Changing page size in an address-based data storage system

A data storage system, comprising:

• processing circuitry and memory coupled to the processing circuitry, the memory storing instructions, wherein the instructions, when executed by the processing circuitry, cause the processing circuitry to:
• initially process host I/O requests directed to a logical storage volume by accessing physical pages of non-volatile data storage having a default page size;
• receive an indication of an optimal page size for the logical storage volume;
• and
• change the size of the physical pages of non-volatile data storage accessed to process host I/O requests directed to the logical storage volume from the default page size to the optimal page size for the logical storage volume by changing a size of physical pages of non-volatile data storage indicated by a mapping structure that maps logical addresses for the logical storage volume to corresponding physical pages of non-volatile data storage from the default page size to the optimal page size for the logical storage volume.

A computer program product, comprising:

• a non-transitory, computer-readable medium having instructions stored thereon that, when executed by processing circuitry in a data storage system, cause the processing circuitry to perform a method comprising:
• initially processing host I/O requests directed to a logical storage volume by accessing physical pages of non-volatile data storage having a default page size;
• receiving an indication of an optimal page size for the logical storage volume;
• and
• changing the size of the physical pages of non-volatile data storage accessed to process host I/O requests directed to the logical storage volume from the default page size to the optimal page size for the logical storage volume by changing a size of physical pages of non-volatile data storage indicated by a mapping structure that maps logical addresses for the logical storage volume to corresponding physical pages of non-volatile data storage from the default page size to the optimal page size for the logical storage volume.
