Method, electronic device and computer program product for storage management

An electronic device, comprising:

• at least one processing unit;
• and
• at least one memory coupled to the at least one processing unit and storing instructions configured to be executed by the at least one processing unit, wherein when executed by the at least one processing unit, the instructions cause the device to perform actions comprising:
• acquiring capacities of a plurality of disks configured to provide redundant storage;
• determining, based on the capacities of the plurality of disks, a first total capacity corresponding to a first candidate scheme of the redundant storage and a second total capacity corresponding to a second candidate scheme of the redundant storage, all of the plurality of disks being used in the first candidate scheme, and a part of the plurality of disks being used in the second candidate scheme;
• and
• determining a target scheme of the redundant storage from the first candidate scheme and the second candidate scheme based on the first total capacity and the second total capacity.

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

• the set of instructions, when carried out by computerized circuitry, causing the computerized circuitry to perform a method of:
• acquiring capacities of a plurality of disks configured to provide redundant storage;
• determining, based on the capacities of the plurality of disks, a first total capacity corresponding to a first candidate scheme of the redundant storage and a second total capacity corresponding to a second candidate scheme of the redundant storage, all of the plurality of disks being used in the first candidate scheme, and a part of the plurality of disks being used in the second candidate scheme;
• and
• determining a target scheme of the redundant storage from the first candidate scheme and the second candidate scheme based on the first total capacity and the second total capacity.
