A device for managing a storage system, comprising:

• at least one processing unit;
• and
• at least one memory coupled to the at least one processing unit and storing instructions to be executed by the at least one processing unit, the instructions, when being executed by the at least one processing unit, causing the device to perform acts comprising:
• determining a size of a data information indicating area in the storage system, the data information indicating area indicating content information related to a slice group including multiple slices, the slice group being the smallest data granularity for storage processor access associated with the storage system;
• determining a correspondence between the size of the data information indicating area and a size of the slice group;
• and
• determining, based on the size of the data information indicating area and the correspondence, the size of the slice group.

A computer program product having a non-transitory computer readable medium which stores a set of instructions to manage a storage system;

• the set of instructions, when carried out by computerized circuitry of the storage system, causing the computerized circuitry to perform a method of:
• determining a size of a data information indicating area in the storage system, the data information indicating area indicating content information related to a slice group including multiple slices, the slice group being the smallest data granularity for storage processor access associated with the storage system;
• determining a correspondence between the size of the data information indicating area and a size of the slice group;
• and
• determining, based on the size of the data information indicating area and the correspondence, the size of the slice group.
