Method of processing a input-output request, an electronic device, and a computer program product

An electronic device, including:

• 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 the instructions, when being executed by the at least one processing unit, cause the device to perform actions including:
• receiving an input/output request for data stored in a second storage means of a storage system;
• determining a use frequency of the data;
• moving the data from the second storage means into a first storage means in the storage system if it is determined that the use frequency is higher than a threshold frequency and the input/output request is a read request, an input/output speed of the first storage means being higher than that of the second storage means;
• and
• writing, if it is determined that the use frequency is higher than the threshold frequency and the input/output request is a write request that includes update data, the update data as the data into the first storage means.

A computer program product having a non-transitory computer readable medium which stores a set of instructions to process an input/output request;

• the set of instructions, when carried out by computerized circuitry, causing the computerized circuitry to perform a method of:
• receiving an input/output request for data stored in a second storage means of a storage system;
• determining a use frequency of the data;
• moving the data from the second storage means into a first storage means in the storage system if it is determined that the use frequency is higher than a threshold frequency and the input/output request is a read request, an input/output speed of the first storage means being higher than that of the second storage means;
• and
• writing, if it is determined that the use frequency is higher than the threshold frequency and the input/output request is a write request that includes update data, the update data as the data into the first storage means.
