Abstract:
The present disclosure provides a storage system for data read and write. One embodiment of the storage system includes an origination device that is configured to receive a request for a logical block addressing-based operation on a volume, convert the logical block addressing-based operation request into a key addressing-based operation request carrying a key corresponding to data to be operated, and send the key addressing-based operation request to a routing library; the routing library is configured to receive the key addressing-based operation request, hash the key corresponding to the data to be operated, determine that a storage node taking charge of a hash region in which the hashed key is located is the master storage node, send the key addressing-based operation request to the master storage node of the data to be operated.
