METHODS AND APPARATUS FOR DISTRIBUTING DATA WITHIN A STORAGE AREA NETWORK

摘要

Methods and apparatus are provided for moving data between storage devices when a source storage device is becoming a bottleneck. One or more blocks of data are identified as blocks to be moved or replicated from the source storage device to one or more other storage devices. The one or more other storage devices are selected and copy services are used to move the blocks from the source storage device to the one or more other storage devices. A metadata store is updated with locations of the blocks that have been moved.
