DATA DEDUPLICATION USING A SOLID STATE DRIVE CONTROLLER

摘要

A data deduplication method is executed by a controller for a solid state drive (SSD). The controller receives a signature for a block of data. The controller performs a comparison of the signature and information in a signature library and determines whether or not the signature matches the information. The controller sends a signal that indicates a result of the comparison. If the signature and the information match then the signal has a first value indicating that the block of data is already stored on the SSD; if the signature and the information do not match then the signal has a second value that is different than the first value.

1. A data deduplication method executed by a controller for a solid state drive (SSD), the method comprising:
receiving, by the controller and from a central processing unit (CPU), a signature for a block of data; determining, by the controller, whether the signature matches information in a signature library; and sending a signal from the controller to the CPU that indicates a result of said determining, wherein if the signature matches information in the signature library then the signal has a first value indicating that the block of data is already stored on the SSD and wherein further if the signature does not match information in the signature library then the signal has a second value that is different than the first value.
