Abstract

Techniques manage an input/output (I/O) operation. Such techniques involve estimating a first storage area in a storage device to be accessed by an upcoming random I/O operation, first data being stored in the estimated first storage area. Such techniques further involve, before the random I/O operation is executed, pre-fetching the first data from the first storage area into a cache associated with the storage device. Such techniques enable implementation of the cache pre-fetch for random I/O operations, thereby effectively improving the performance of data access.
