A network storage server system includes a presentation layer that presents multiple namespaces over the same data stored in an object store, allowing users to simultaneously access data over multiple protocols. The system supports object location independence of the stored data objects by introducing a layer of indirection between directory entries and storage locations of stored data objects. In one embodiment, the directory entry of a data object points to a redirector file that includes an object locator (e.g., an object handle or a global object ID) of the data object. The directory entries of data objects are stored in a directory namespace (e.g., NAS path namespace). In another embodiment, a global object ID of the data object is directly encoded within the directory entry of the data object.
