摘要：A virtual volume module in a host system provides virtual volume view to user-level and system-level applications executing on the host system. The virtual volumemodule maps I/O from the applications which are directed to a virtual volume to a first
physical volume in a first storage system. When necessary, the virtual volume module canmap application I/O's to a second volume in a second storage system. The secondstorage system replicates data in the first storage system, so that when re-mappingoccurs it is transparent to the applications running on the host system.
