Abstract
A method for storing digital data in a virtualization storage system which includes the step of creating a virtual storage volume and communicating the location of the virtual storage volume to a storage subsystem. The storage subsystem identifies a mapping type between the virtual volume and at least one virtual volume-related physical device and then creates virtualization metadata describing the virtual volume, the mapping type, and the virtual volume-related physical device. The storage subsystem mediates the storing of at least a portion of the virtualization metadata on the virtual volume-related physical device as device stored metadata. A portion of the stored virtualization metadata is provided to then one or more using systems which utilize this metadata to update the virtual volume information contained therein. A virtualization storage system implements one or more steps of the methods of the invention.
