Abstract
A mechanism is provided for thin provisioning. An original time-domain sequence of a load parameter of storage resources already allocated to an application program is collected. A future load peak time period of the storage resources already allocated to the application program is determined based on the collected original time-domain sequence of the load parameter. A new storage resource unit from a high-speed storage is allocated in response to receipt of a request to allocate the new storage resource unit to the application program in the future load peak time period. On an occasion of thin provisioning, whether the physical storage resources newly allocated to the application program are located in a low-speed storage or a high-speed storage is determined according to the accesses of the application program to the already-allocated physical storage resources.
