Method and apparatus for performing data-accessing management in a storage server

A host device, comprising:

• a control circuit, arranged to control the host device to perform data-accessing management in a storage server, wherein the storage server comprises the host device and a plurality of storage devices that are coupled to the host device, the host device is arranged to control operations of the storage server, and the plurality of storage devices are arranged to store information for the storage server, wherein:
• in response to a client request of writing a first set of data into the storage server, the host device triggers broadcasting an internal request corresponding to the client request toward each storage device of the plurality of storage devices;
• and
• through the internal request corresponding to the client request, the host device controls said each storage device of the plurality of storage devices to search for the first set of data in said each storage device to determine whether the first set of data has been stored in any storage device of the plurality of storage devices, for controlling the storage server completing the client request without duplication of the first set of data within the storage server.

A storage device, comprising:

• a non-volatile (NV) memory, wherein the NV memory comprises at least one NV memory element;
• and
• a memory controller, arranged to control accessing of the NV memory, to allow a host device to access the NV memory through the memory controller, for performing data-accessing management in a storage server, wherein the storage server comprises the host device and a plurality of storage devices that are coupled to the host device, the host device is arranged to control operations of the storage server, and the plurality of storage devices are arranged to store information for the storage server, wherein:
• in response to a client request of writing a first set of data into the storage server, the host device triggers broadcasting an internal request corresponding to the client request toward each storage device of the plurality of storage devices, wherein the plurality of storage devices comprise the storage device;
• and
• in response to the internal request corresponding to the client request, said each storage device of the plurality of storage devices searches for the first set of data in said each storage device to determine whether the first set of data has been stored in any storage device of the plurality of storage devices, for controlling the storage server completing the client request without duplication of the first set of data within the storage server.

A controller of a storage device, the storage device comprising the controller and a non-volatile (NV) memory, the NV memory comprising at least one NV memory element, the controller comprising:

• a processing circuit, arranged to control operations of the controller for controlling accessing of the NV memory, to allow a host device to access the NV memory through the controller, for performing data-accessing management in a storage server, wherein the storage server comprises the host device and a plurality of storage devices that are coupled to the host device, the host device is arranged to control operations of the storage server, and the plurality of storage devices are arranged to store information for the storage server, wherein:
• in response to a client request of writing a first set of data into the storage server, the host device triggers broadcasting an internal request corresponding to the client request toward each storage device of the plurality of storage devices, wherein the plurality of storage devices comprise the storage device;
• and
• in response to the internal request corresponding to the client request, said each storage device of the plurality of storage devices searches for the first set of data in said each storage device to determine whether the first set of data has been stored in any storage device of the plurality of storage devices, for controlling the storage server completing the client request without duplication of the first set of data within the storage server.
