Method and apparatus for performing pipeline-based accessing management in a storage server with aid of caching metadata with cache module which is hardware pipeline module during processing object write command
A method for performing pipeline-based accessing management in a storage server and associated apparatus are provided. The method includes: in response to a request of writing user data into the storage server, utilizing a host device within the storage server to write the user data into a storage device layer of the storage server and start processing an object write command corresponding to the request of writing the user data with a pipeline architecture of the storage server; utilizing the host device to input metadata corresponding to the user data into at least one pipeline within the pipeline architecture; and utilizing the host device to cache the metadata with a first cache module of the pipeline, for controlling the storage server completing the request without generating write amplification of the metadata, wherein the first cache module is a hardware pipeline module outside the storage device layer.
