    Abstract: The present disclosure provides a data read and write method and apparatus and a storage system. The data read and write method includes: receiving, by a block storage driver of an origination device, a request for an LBA-based operation on a volume; converting the LBA-based operation request into a Key addressing-based operation request; and sending the Key addressing-based operation request to a routing library. Therefore, according to the present disclosure, reliability, availability, extensibility, and cheapness of the storage system may be improved, satisfying mass storage requirements for high extensibility, high reliability, high availability, and cheapness.

    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.
