-can be used to model storage:
+\subsubsection pf_sto_conc Storage - Main Concepts
+
+The storage facilities implemented in SimGrid help to model (and account for)
+storage devices, such as tapes, hard-drives, CD or DVD devices etc.
+A typical situation is depicted in the figure below:
+

+\image latex ./webcruft/storage_sample_scenario.png "storage_sample_scenario" width=\textwidth
+
+In this figure, two hosts called Bob and Alice are interconnected via a network
+and each host is physically attached to a disk; it is not only possible for each host to
+mount the disk they are attached to directly, but they can also mount disks
+that are in a remote location. In this example, Bob mounts Alice's disk remotely
+and accesses the storage via the network.
+
+SimGrid provides 3 different entities that can be used to model setups
+that include storage facilities:
