Abstract
A method for data storage includes, in a system that includes one or more storage controllers, one or more servers and one or more storage devices, defining one or more data structures that represent thinly-provisioned user volumes used by the servers in storing data on the storage devices. One or more of the data structures are shared among the storage controllers and the servers. One or more of the user volumes are accessed by the servers, using the shared data structures and without executing code on the storage controllers.
