METHOD FOR DISK DEFRAG HANDLING IN SOLID STATE DRIVE CACHING ENVIRONMENT

摘要

According to an embodiment of the present invention, a method of managing target disk access requests during disk defragmentation in a solis state drive caching environment may include detecting a request for access to a target storage device; If the request is a write request, do not write the data associated with the request to the caching device, write the data to the target storage device, if the request is a read request, read the data associated with the request, and mark it to discard the data stored on the caching device. Doing; And discarding the marked data from the caching apparatus.
