Patent abstract
A tiered storage system according to the present invention provides for the management of migration groups. When a migration group is defined, a reference tier position is determined and the relative tier position of each constituent logical device is determined. Movement of a migration group involves migrating data in its constituent logical devices to target logical devices. The migration group is then defined by the target devices. A virtualization system makes the transition transparent to host devices.
