 Virtual Media feature supports multiple, simultaneous connections in both
 modes.
 
+### Asynchronicity
+
+Mounting and unmounting of remote device could be time consuming. Virtual
+Media shall support asynchronicity at the level of DBus and optionally Redfish
+API.
+
+Default timeouts for DBus (25 seconds) and for Redfish (60 seconds) may be
+insufficient to perform mounting and unmounting in some cases.
+
+Asynchronous responses will be described later on in appropriate sections.

 ### Network Block Device (NBD)
 
 Reader can notice that most connections on diagram are based on Network Block

 Depends on object path, object will expose different interface for mounting image.
 
+Mounting can be a time consuming task, so event driven mechanis has to be
+introduced. Mount and Unmount calls will trigger asynchronous action and will
+end immediately, giving appropriate signal containing status on task
+completion.
