Abstract:
Techniques perform storage management. Such techniques involve, in response to an operation to be performed on data in a cache page, determining a first cache page reference corresponding to the cache page, the first cache page reference comprising a pointer value indicating the cache page. Such techniques further involve creating, based on the first cache page reference and the operation, a second cache page reference corresponding to the cache page, the second cache page reference comprising the pointer value. Such techniques further involve performing the operation on the data in the cache page via the second cache page reference. One cache page can correspond to a plurality of cache page references. Additionally, copy of data from one cache page to a further cache page can be effectively avoided, so as to enhance input/output performance and utilization rate of storage space.
