1. A method of thin provisioning storage resources associated with an application program, the method comprising: collecting an original time-domain sequence of a load parameter of the storage resources already allocated to the application program; determining a future period of time in which a load, of the storage resources allocated to the application program, would be greater than a predetermined load threshold based on the collected original time-domain sequence of the load parameter by: determining a historical period of time in which a load of the storage resources allocated to the application program was greater than the predetermined load threshold according to the original time-domain sequence of the load parameter; obtaining a load cycle of the storage resources allocated to the application program by: removing a linear component from the original time-domain sequence of the load parameter before performing a time-frequency transform on the original time-domain sequence of the load parameter, wherein the linear component is obtained from the original time-domain sequence of the load parameters by at least one of a linear fitting analysis or linear regression analysis; performing the time-frequency transform on the original time-domain sequence of the load parameter to obtain a frequency-domain characteristic of the load parameter; and estimating the load cycle of the storage resources allocated to the application program according to the frequency-domain characteristic of the load parameter; and determining the future period of time in which the load, of the storage resources allocated to the application program, would be greater than the predetermined load threshold according to the historical period of time and the load cycle; and allocating a new storage resource unit from a high-speed storage in response to receipt of a request to allocate the new storage resource unit to the application program in the future period of time in order that an existing allocation from a low-speed storage is not moved to the high-speed storage.
