System and method for providing a unified storage system that supports file/object duality

摘要

Methods and systems that permit file protocols and object protocols to co-exist using a file namespace and an object namespace in a unified storage system are disclosed. Data stored in the unified storage system are file-objects that preserve the behaviors expected by both file clients and object clients.

1. A method for updating file objects based on modifications to file representations of data entities, said method comprising:
generating a file representation of a data entity in a storage system; generating a first object representation of the data entity in the storage system; generating a first object namespace redirector that includes a pointer to the first object representation; generating a file namespace redirector that includes a pointer to the file representation and a pointer to the first object namespace redirector; and if the file representation has been modified,
copying data content of the modified file representation to a second object representation;generating a second object namespace redirector that includes a pointer to the second object representation; andmodifying the first object namespace redirector pointer to point to the second object namespace redirector.
