Patent attributes
Techniques are described for performing a copy operation. A first request is received to perform a copy operation to copy source data from a source area to a target area. The first request is partitioned into a plurality of other requests. Each of the plurality of other requests being a request to copy a portion of source data located in the source area to a corresponding location in the target area. A first number of the other requests is issued. Responsive to the issued requests, a copy operation is performed to copy a portion of the source data from the source area to the target area. Completion of a second number of the issued other requests is detected. The second number corresponds to a fraction of the first number such that the second number is greater than one and less than the first number. Upon detecting completion of the second number, a third number of the other requests is issued to copy another portion of the source data from the source area to the target area. The third number corresponding to the second number of the issued other requests detected as complete.
