METHOD AND APPARATUS FOR TRANSFERRING DATA BETWEEN A PRIMARY STORAGE SYSTEM AND A SECONDARY STORAGE SYSTEM USING A BRIDGE VOLUME

摘要

A method and apparatus for transferring data from a first storage system (500) to a second storage system (512) in which the first storage system includes a first plurality of storage devices (502-506) and the second storage system includes a second plurality of storage devices (514-518). Data is transferred using a pair of devices selected for transferring data for all of the storage devices. Data to be transferred from source storage devices (502-506) within the first plurality of storage devices is placed or queued on a selected primary storage device (508) within the first plurality of storage devices. The data is sent to a selected secondary storage device (520) within the plurality of storage devices. The data is relocated from the selected secondary storage device to target storage devices (514-518) within the second plurality of storage devices.
