Abstract
Data protection operations based on direct storage access. Data protection operations that involve large data transfers are optimized or improved by transferring the data using a communication path that includes direct access to disks of a storage array. This avoids latencies associated with transferring data through the layers of the storage array. The locations of the data to be transferred are identified and provided to an appliance. The appliance can then read and transfer the data over a communication path that includes direct disk access.
Claims1
A method for performing a data protection operation, comprising:
- accessing, by a source appliance, metadata associated with data stored in a source storage array, wherein the metadata identifies data to be transferred to a target storage array;
- transferring the metadata to a target appliance using a first communication path;
- transferring the data identified in the metadata to the target storage array using a second communication path that is different from the first communication path, wherein the second communication path includes directly accessing a disk array of the source storage array without using a front end of the source storage array.
