Abstract

In a storage processor having a provider framework, one embodiment is directed to a method for providing an object. The method includes receiving, by a data access layer of the provider framework, an object request from a client device, the object request identifying at least one object. The method includes applying, by the data access layer, a mapping module to the object request to access object data associated with the object request. The method includes generating, by the data access layer, the at least one object identified in the object request. The method includes forwarding, by the data access layer, the at least one object to the client device.
