FlashCopy® is faster than traditional methods of data movement, especially for moving large amounts of data. DFSMSdss can use the FlashCopy feature of the Enterprise Storage Server® (ESS) to quickly move the data from the source location to the target location. The source devices and the target devices must be in the same ESS, and the data to be moved must not need manipulation.
