DATA STORAGE SYSTEM AND METHOD OF PROCESSING A DATA ACCESS REQUEST

摘要

A data storage system includes a plurality of servers, a plurality of external interface providers each deployed on one of the servers, and a plurality of data storage controllers each deployed on one of the servers. Each of the providers is configured to receive a data access request, to identify one of the controllers that can satisfy the request, and to forward the request to the identified controller. The system further includes a plurality of data storage modules independent of the servers. The providers, controllers and modules are in communication with each other. Each of the controllers exclusively manages a portion of data content in at least one of the modules, and satisfies data access requests received from the providers by accessing the portion of data content in the at least one module.
